A Truly 'laboring' Labor Day weekend!
My fall calving got started this past few days, and because one of the calves born was so very small I decided to try out a set of old bathroom scales that have a big platform and an elevated dial with big numbers for viewing weight results. This little heifer calf was a surprise finding on August 30th when the Animal Compassion Foundation was having another visit with my herd. Anne was thinking on her feet and volunteered her belt to use to measure the newborn and a pen to mark the spot. She was obviously a very little girl, and I ventured the guess that she couldn't weight more than 45 pounds.
We got back to the house and measured Anne's belt and found that she had measured 24 1/2 inches around, and it was a good snug belt measure around her heart girth, the little heifer was totally interested and cooperative. I figured the belt measure probably, because it was a thick leather belt, added some length to the measurement, and later on that evening I went out and measured her again with my tape, and I measured her at 24 inches. While 24 inches got her closer to the mark when you use the tape conversion chart in the Breeder's Guide, I still wasn't convinced that her actual weight was 51 pounds, which is what you get when you use the 4.5 pound increments to back into an off the chart 24 inch heart girth.
The following day I decided to try out my old scales on this little heifer. I found a light weight section of that stick on the floor tile type stuff in the barn, and decided that would work fine. It was nice and sturdy, yet was very manageable. I put the section of floor tile down on the ground, put the scales on my new weighing platform, and weighed her and myself twice for good measure. She was an exact 40 pound little heifer. The difference of 11 pounds is very significant, that is over a 25% error in birth weight estimation.
I decided to go through this same process with each of my newborns. Besides this little heifer, I had four other calves born August 30th through Sept. 2nd. Of those three of them were cooperative, the 27 1/2 inch bull calf born on August 30 to Hill's Dana already found it too much grand fun to scamper about for me pick him and get an actual weight.
August 31st a heifer calf was born to MsRae. She measured 26 inches, and per the tape conversion chart should have weighed 60 pounds, but in fact she weighed more! She had an actual weight of 65 pounds. I also had Mike confirm these same results himself, and it was an accurate weight of 65 pounds -- and she is pictured here.
September 1st a bull calf was born to Madonna (and I actually happened to be out at pasture hanging around in the Ranger and she calved about 40 feet away from me!). This bull calf measured 26 1/4 inches, and had an actual weight of 60 pounds. So in this instance the tape conversion to weight was quite acceptably accurate, and again I had Mike duplicate the weighing process for confirmation.
Then on the afternoon of September 2nd, Polly (pictured here to the right)decided it was time to calve. This calving went on for a bit too long for my comfort, I even called to try to reach a vet just in case I had a problem on my hands. But in between rushing to the house and calling the vet and leaving a message of impending problems, she had delivered a healthy bull calf. (So of course I rushed back to the house and left another message for the vet that all was well!) I tape measured this newborn at a whopping 27 1/2 inches, and had Mike confirm the tape measurement as well this time. We both weighed the little guy and he weighed all of 60 pounds. But, per the tape conversion he should have weighed about 67 pounds -- a greater than 10% error, which in this business is a highly material error.
So what does all this mean to the breeder who relies on tape measure conversion to estimate weight? It means you probably ought to be getting some actual weights as well until, or if, you feel comfortable visually estimating weight and understanding how the tape should perhaps be adjusted for what your eyes tell you.
As well, it could be that I don't handle the tape measure properly. With that in mind, if I haven't been pulling the tape snugly enough around the heart girth then I have a whole lot of historical birth weights that are over-estimated. However, the results from the little study shown here indicate the tape can create error both on the high and low side. I am going to continue to both use a tape measure for weight and get an actual weight with the remainder of my fall calves to get a sense of the average error rate as well as try to understand why.
Earlier I mentioned that Polly (who is also a first calf heifer) was having a more lengthy birth than I like to see. She actually was effectively yelling with her efforts, so I was even more alarmed. It's very unusual for any of my cattle to get vocal over calving. Polly's bull calf measured 27 1/2 inches, yet it only weighed 60 pounds. So, what was structurally different in Polly's bull versus Madonna's (also a first calf heifer) bull that would create an error using a tape measure? To my eye he has wider shoulders and is thicker through the heart girth, a deeper little guy -- yet at a glance looks about the same size/stature as Madonna's 26 1/4 inch bull. So obviously the confirmation of the newborn has a great impact on using a tape measure for an accurate birth weight.
MsRae's heifer is an example of the error to the light side using a tape measure. She weighed a full five pounds more than the tape measured estimate. Why? Perhaps because she has good balance all over, her dam certainly does. How does the tape measure consider a deep evenly made newborn that extends on through to the hind quarters? I don't think it can.
Regardless, I'll continue this small study of tape versus actual weight and see what the final results tell me about my own errors in tape measuring as well as errors due to the actual structure of the calf, and periodically update those results here on my blog.
British White Cattle are performing with excellence in Southeast Texas and around the world. They are genetically docile and uniquely beautiful, as well as being superior beef cattle to have at pasture and on your plate.

Environmental and Nutritional Effects on Beef Tenderness, Marbling, & Overall Palatibility
Beef calves fed on 100% high concentrate grain from weaning to finish in a feedlot environment results in the least desirable beef eating experience for the American consumer, and the least desirable muscle to bone ratio in the final carcass, which directly impacts the end revenues of the beef industry. Conventional high concentrate grain feeding, from the zero pasture stocker phase on through to the continued high concentrate feedlot and finish of beef calves, is often perceived or touted as the only course of feeding that will result in tender, well-marbled beef in an animal genetically predisposed to marble well. The result of a 2002 study funded by Beef Checkoff dollars and conducted with the oversight of the Texas Beef Council suggests that is not the reality.
With the current corn ethanol craze and subsequent corn production targeted to fuel the new corn ethanol market, many cow/calf operations are re-evaluating the cost/benefit of their programs. The majority of cow/calf operations in the United States that provide beef to the American consumer are small shops bringing fifty or fewer beef calves to the local market annually. Browsing through this Texas Beef Council study conducted by Texas A&M one realizes that corn, or any grain, can be largely side-stepped for the majority of the beef calves life when there is ample grass and legume pasture available.
While this study has a bit of age on it, it remains the only study sponsored by the Texas Beef Council with the goal of evaluating various backgrounding scenarios and their impact on Tenderness, Marbling, Palatability, and other sensory factors involved in the enjoyment of a beef steak. The eight study groups were located in three distinct geographical areas of Texas in the interest of evaluating the impact of environment on the final carcass attributes. The East Texas studies conducted in Overton, Texas out-performed the other groups in many key areas: finish weight, ribeye area, and backfat thickness.
This 2002 Texas A&M conducted study evaluated eight different pasturing and feeding regimens to try and understand nutritional and environmental factors that impact variability in Texas beef. While the stated focus was primarily carcass tenderness, the results provided insight into all the desirable primary attributes of beef. Of the eight study groups, the "McGregor-Calf Fed" (MCF) group receiving high concentrated grain rations from weaning to harvest scored the poorest in many key areas -- but perhaps most surprising was the detrimental impact on ribeye area, backfat, and finish weight. All of these attributes were noticeably deficient in the MCF group in comparison to the Overton/East Texas and Uvalde/South Texas study groups which were backgrounded on pasture and finished the final approximately 4 months on high grain concentrate -- with the East Texas study groups providing significantly superior results overall.
There are two major factors in a consumers enjoyment of beef -- Tenderness and Marbling. The primary stated focus of this Texas Beef Council study was carcass Tenderness. While all study groups were within an immaterial range of one another for initial Tenderness scoring, the MCF high concentrate (post-weaning to finish)group had the actual least tender carcass upon initial harvest than any of the other study groups.
After 14 days of aging the Tenderness scores were comparable across all study groups. What is significantly missing from this reported study is the sire parentage of the many groups. We are told that Half-blood Bos indicus (Brahman)-influenced steers raised at the Agricultural Research Center, Texas Agriculture Experiment Station in McGregor, Texas were used in this study to understand the impact of environment (south, east and central Texas) and nutrition (low versus high grain supplementation) immediately post-weaning and prior to feedlot feeding on the growth, composition and eating characteristics of beef, but we are not told if the steers in all study groups were half-siblings, sired by the same bull. This is critical information, inexplicably withheld, for purposes of evaluation of the final, very comparable, results across the board for Tenderness and Marbling.
At the time of this 2002 study the calcium dependent protease inhibitor, calpistatin, had been identified as a key component present in a live animal that greatly increases that animals genetic potential to express Tenderness in the final carcass product. Today, a cattle rancher can pull a few tail hairs and send them off for genetic testing to determine whether his prize bull or cow has the genetics to potentially produce a tender as well as an optimal marbled carcass in their offspring. This genetic testing has become an invaluable tool for seedstock producers seeking to create key bulls and cows that will produce offspring that will excel in the commercial beef market for Tenderness and Marbling.
However, despite this stated fore-knowledge of the impact of Calpistatin, one of two key genetic attributes for Tenderness known today in the year 2007, the results of this study cloud the impact of Calpistatin on the study results. One is left with the sense that the genetic comparability of the steers evaluated, which is a stated parameter of the test, is the driving reason for the comparability of carcass Tenderness scores. While the study addresses and theoretically evaluates the Calpistatin in the resulting beef carcasses, it mysteriously couches the tested Calpistatin results in non-layman gibberish and declines to even address its existence or significance in the final narrative summation of results -- it is found only in the summation charting. As all carcasses resulting from this study had comparable Tenderness scores via Warner Bratzler Shear Force measures, it may be that the presence or absence of the identified Calpistatin gene had no material impact on actual carcass Tenderness.
Perhaps of even greater interest are the Marbling scores of the study groups. Despite backgrounding via rotational or continuous grazing in either North, South, or East Texas -- or no grazing as is the case with the high grain concentrate from weaning to finish MCF group -- marbling scores in all study groups were not materially different. However, the MCF group had significantly higher percentage carcass fat scores over all other groups, which is undesirable in today’s market and had no additive impact on actual Marbling scores of the final beef product compared to the others, and thus no positive impact on the final value of the beef carcass -- the excess fat is waste.
Of major importance to the beef cattle producer would be the expense of the constant level of "high concentrate" grain feed from weaning to finish of the McGregor-Calf Fed (MCF) group -- which had the lightest finish weight, and as well the highest fat percentage of the harvested carcass weights. While the MCF group had comparable marbling to the other groups, the higher fat level/percentage to accomplish this feat is essentially money down the drain for packing shops such as Cargill or Smith & Company, as well as for the feeder and cow/calf producer who so costly and conscientiously kept that supplemental "high concentrate" grain at the ready in their post weaning/backgrounding phase of production that they perceive should result in their highest profit at the local auction barn or via a direct order buyer..
Today, beef cattle producers are faced with increasing costs of corn. If the corn ethanol craze continues unabated in the coming years, the ease and value of shoveling corn at a growing calf will be re-evaluated for the ultimate financial gain to the beef producer, stocker, and finisher. The use of genetic testing for inherent ability to produce a Tender and well Marbled carcass will become one of increasing importance as reflected in the results of this Texas Beef Council sponsored study.
The day is likely well in hand when the small beef producer, the primary entity that grows our beef in America, must evaluate the financial pros and cons of raising their calves on expensive corn or other sundry grain mixes, or the less costly raising of their calves on pasture grasses and pasture legumes that provide both the major beef packing houses and the American consumer with an end product that has less fat and comparable to greater muscle, marbling, and tenderness on a higher nutritional plane than that of 100% grain fed and finished beef.
The small shop beef producer who raises a high end, healthy product has only one primary venue for realizing the value that should be derived from their superior beef product, and that is the direct marketing of wholes, halves, splits, or pre-packaged cuts of their beef. While this is measurably a quite profitable venue, their remains the fact that many beef consumers have neither the time, the space, or perhaps the funds to purchase healthy, clean beef in bulk in this manner. It will be the small shop grocery markets that will on the front end provide a venue for the sale on a larger scale of this superior healthy beef product.
Of perhaps even greater difficulty to the small shop grassfed beef producer, at least in this part of Southeast Texas, is finding an abattoir that is either State or USDA licensed. They are as few and far between as a cow having triplets. So a rancher producing healthy grassfed beef for the local Southeast Texas market has no retail venue to market that beef -- they are forced to sell it on the basis of hanging weight at a less than desirable slaughterhouse to their customers. Many times it matters not how much the need for aging, whether grain finished or grass finished, is important to the optimal result for the ranchers' customers. If the person in charge in the local butcher shop doesn't wish to age a carcass, or doesn't think/understand that it serves a purpose anyway, the customer gets the news when they arrive to pick up their beef --- and worse, the beef producer ultimately hears from an unhappy customer.
Maybe it is time for apartment architects, home architects, to begin to consider in their designs the presence of a large deep freeze as an integral part of home design. With this in place, more consumers who desire a healthier beef product will have the space readily at hand to store for a season the beef they wish for themselves and their family to consume as a staple in their diet.

Ethanol Refineries - Fair or Foul?
by Jimmie L. West
The Environmental Protection Agency, just a few short weeks ago, revised downward the pollution control standards for ethanol producing plants. It wasn't exactly major news for the networks -- but it should have been. This action by the EPA no doubt is a result of strong lobbying efforts from major corn and ethanol producers. Prior to this revision, the threshold of toxic emissions allowed before an ethanol producing site must install the latest pollution controls was 100 tons annually; the EPA's April revision more than doubles that threshold to 250 annual tons of toxic emissions. In addition, the EPA agreed to allow so-called 'fugitive' emissions from small vents or pipes to be excluded from computation in reaching the new 250 ton pollution emission threshold for ethanol plants.
While many U.S. farmers and rural communities are eagerly on board for raising more corn and building ethanol plants in their communities -- many are not. The concerns abound regarding the permanent loss of quality of air and life and many are fighting to stop the building of ethanol plants in their rural communities. The EPA's willingness to relax pollution control standards for ethanol production facilities certainly strengthens the argument and position of those farming communities fighting to keep the fumes of ethanol production out of their air space.
One of the primary arguments for the use of ethanol, or ethanol mixed with gasoline, is that it reduces carbon monoxide emissions, which sounds just grand on the surface. However, what is largely absent from all ethanol rhetoric is that ethanol emissions contain "nitrogen oxides, acetaldehyde, and peroxy-acetyl nitrate". (Patzek, 2004) And that's just to name a few of the toxic by-products of cooling off the earth by pumping some ethanol into your tank.
What a joke. And the jokes on us. Do you really want to be an Ethanol Patriot and pump bio-fuel into your car? You see, ethanol is pretty volatile, it will break down while you are pumping it into your car. Take a deep breath, pull those carcinogens into your lungs - could that be the new American way to save the earth?
The State of Minnesota has embraced on a fairly large scale the construction and operation of ethanol plants, having some 16 ethanol plants in operation, and several more are under construction today. The following is an excerpt from the Minnesota Pollution Control Agency (MPCA) web site -- and it surely must be scary for a state or region to feel like a virtual guinea pig or lab rat as the emissions from ethanol plants are studied after the fact to determine just what is coming out of an ethanol smoke stack.
"Consent decrees negotiated with the plant owners revealed underreported emissions and required pollution control equipment to be installed in an effort to accurately quantify and reduce air emissions. Most facilities consistently reported similar constituents including detectable levels of acetaldehyde, acetic acid, formaldehyde, ethanol and methanol, although there was considerable variation in quantities of analytes among facilities and among different processes at a facility. Although the data set is small, it is the most extensive available. Further systematic testing is necessary to thoroughly characterize the complex gas stream from various stages of the ethanol production process. Until additional data are obtained and analyzed, we cannot say with complete certainty whether data gaps have implications for risk analysis." Any state, any community, considering building a 'biorefinery' to produce ethanol should visit the MPCA web site -- it is pretty darn scary, and it looks like it's a money pit from an administrative and regulatory viewpoint as well.
The more than 200 U.S. ethanol plants in operation or under construction emit thousands of tons of pollutants a year, including nitrogen oxides, a key element of smog and damage to the ozone layer. As the EPA has apparently little concern for the air pollution of rural areas from ethanol production, other States are hopefully investigating ethanol plant emissions and implementing their own regulatory standards to ensure the cleanest air possible for those who must now live with an industrial smoke stack next door.
The Renewable Fuels Association (RFA), which bills itself as the national trade association for the U.S. ethanol industry, has a very lame response on their web site to the results of a very recent Stanford University study that concluded there were risks from ethanol emissions. Per the RFA, "this study by Professor Jacobson does show that most of the air quality “problems” he identified stem from acetaldehyde that is either emitted directly or results from excessive ethanol emissions. If these problems were found to be serious enough, then regulations could quickly be put into place that would require vehicles . . . meet more stringent ethanol and acetaldehyde emissions standards before they could be certified for sale." Excuse me? Why are we subsidizing the creation of a bio-fuel before we've even fully explored it's new and singular impact on the air we breath? How does this fella know we can find a way to lessen acetaldehyde emissions? He doesn't; he just has to be hopeful and positive, that's his job. By the way, acetaldehyde is a known carcinogen.
Within the EPA's April decision to relax the pollution standards for ethanol refineries, there is an exception made that both undermines the basis for relaxing the standards and clearly shows a lack of concern for the clean air in rural communities: The newly revised EPA standards do not apply to ethanol plants in urban areas where air pollution is already a problem. So, just what does that tell you? Tells me there is known 'bad stuff' coming out of those smoke stacks, and allowing 250 tons to be emitted into good clean country air is a cop out on the part of the EPA.
U.S. ethanol production has jumped more than 300% since the year 2000. Per the RFA in early April, there are currently 114 ethanol biorefineries (RFA's earth friendly term for their ethanol plants) nationwide with the capacity to produce more than 5.6 billion gallons annually. There are 80 ethanol refineries and 7 expansions under construction with a combined annual capacity of more than 6 billion gallons.
The National Corn Growers Association says U.S. corn growers hold the potential to produce 15 billion bushels by 2015 - a third of which could be used to produce some 15 billion gallons of ethanol. But, corn based ethanol producers and farmers don't have a corner on the ethanol market. What happens when the subsidies and tax incentives dry up? or when there is a major long term drought? The Global Warming fanatics might be right. Where does that leave corn based ethanol? Nowhere really. Can that new corn based ethanol plant in Littletown, Kansas be converted to the latest and greatest? If so, at what cost? Or will it eventually become nothing more than a massive incinerator for the worst industrial waste money can produce in the world? I'll leave that possibility for another day -- but it is quite real.
How is it that we as a country have gotten in such a rush to subsidize ethanol production when we have not fully explored all the alternative sources and arrived at the most economic and healthy approach to producing ethanol in the USA? If this were a drug, it would still be under testing.
There are many alternatives to creating ethanol other than from corn that are being explored globally. The one I find most intriguing was recently announced by LanzaTech, a New Zealand based company. They are using bacterial fermentation to convert carbon monoxide into ethanol. Per LanzaTech, this technology could produce 50 billion gallons of ethanol from the world's steel mills alone, turning the liability of carbon emissions into valuable fuels worth over $50 billion per year at very low costs and adding substantial value to the steel industry. There would be some poetic beauty to that alternative, and one that would economically and environmentally have a positive impact on industrialized areas in the USA and around the world -- including Southeast Texas.
Research is underway as well to produce ethanol from other plants, including wheat, oats and barley. Sugar cane is already a viable source of ethanol -- while it is a water needy crop, it can withstand a wide range of drought and freeze conditions, and it's a perennial crop. Others are looking at genetically engineering microbes to produce enzymes that will convert cellulose in crop waste, wood chips and other plants into ethanol. The Energy Department is investing $385 million in six new cellulosic ethanol plants around the country. More than half the ethanol made in Kansas already comes from sorghum, which requires less water than corn.
And speaking of water, do you really find much coming out of Citizen Green's mouth about the massive amount of water required to produce ethanol from corn? How about the enormous fertilize, herbicide, and pesticide requirements for those annual crops of corn, and the post-production waste water the ethanol plant has to find a home for? How will all of this impact the biology of our water, our oceans? Do you know? I didn't think so. Have a chat with a long time resident of the Rio Grande Valley of Texas and see what they have to say about chemical run off from the cotton, grain, and corn fields that makes it's way to the Laguna Madre and impacts the ecosystem of that once pristine bay. Ask them if they willingly drink water out of the tap. Then magnify their response by multiples of......oh, say 100, let's think big, let's think long term ethanol production, long-term blinders. Ouch, it's just too scary. It needs to be curtailed now.
I think most of us would go back to riding a bicycle before we'd knowingly create a national dependency and drain on our water resources just to have ethanol to buzz over to Cousin Joe's for a beer, or Aunt Bet's for bowl of gumbo. We can strap a bottle of water to that bike and life goes on. Suddenly car-pooling wouldn't seem such an irritating idea, after all, we can't live without good clean water -- or air, or for that matter good old Southern cornbread. If this corn ethanol takes off, just how costly will a pound of corn meal be?
If we're going to create a whole new dynamic in America's food supply in order to mitigate our dependence on oil, let's pick something that would have a healthy impact on the American diet. After all, we are the most obese country in the world -- let's fix that problem and at the same time create an alternative bio-fuel. With those joint goals, sugar cane becomes the ultimate ethanol crop with enormous positive consequences for the health of America. No doubt with less sugar in our diet we could breathe a whole lot more of that fouled country air -- our immune systems would be much stronger without all that sugar, and we'd be a lot thinner and could more easily fit in little bitty cars that run on bio-fuel.

Or will it eventually become nothing more than a massive incinerator for the worst industrial waste money can produce in the world? I'll leave that possibility for another day -- but it is quite real.
How is it that we as a country have gotten in such a rush to subsidize ethanol production when we have not fully explored all the alternative sources and arrived at the most economic and healthy approach to producing ethanol in the USA? If this were a drug, it would still be under testing.
There are many alternatives to creating ethanol other than from corn that are being explored globally. The one I find most intriguing was recently announced by LanzaTech, a New Zealand based company. They are using bacterial fermentation to convert carbon monoxide into ethanol. Per LanzaTech, this technology could produce 50 billion gallons of ethanol from the world's steel mills alone, turning the liability of carbon emissions into valuable fuels worth over $50 billion per year at very low costs and adding substantial value to the steel industry. There would be some poetic beauty to that alternative, and one that would economically and environmentally have a positive impact on industrialized areas in the USA and around the world -- including Southeast Texas.
Research is underway as well to produce ethanol from other plants, including wheat, oats and barley. Sugar cane is already a viable source of ethanol -- while it is a water needy crop, it can withstand a wide range of drought and freeze conditions, and it's a perennial crop. Others are looking at genetically engineering microbes to produce enzymes that will convert cellulose in crop waste, wood chips and other plants into ethanol. The Energy Department is investing $385 million in six new cellulosic ethanol plants around the country. More than half the ethanol made in Kansas already comes from sorghum, which requires less water than corn.
And speaking of water, do you really find much coming out of Citizen Green's mouth about the massive amount of water required to produce ethanol from corn? How about the enormous fertilize, herbicide, and pesticide requirements for those annual crops of corn, and the post-production waste water the ethanol plant has to find a home for? How will all of this impact the biology of our water, our oceans? Do you know? I didn't think so. Have a chat with a long time resident of the Rio Grande Valley of Texas and see what they have to say about chemical run off from the cotton, grain, and corn fields that makes it's way to the Laguna Madre and impacts the ecosystem of that once pristine bay. Ask them if they willingly drink water out of the tap. Then magnify their response by multiples of......oh, say 100, let's think big, let's think long term ethanol production, long-term blinders. Ouch, it's just too scary. It needs to be curtailed now.
I think most of us would go back to riding a bicycle before we'd knowingly create a national dependency and drain on our water resources just to have ethanol to buzz over to Cousin Joe's for a beer, or Aunt Bet's for bowl of gumbo. We can strap a bottle of water to that bike and life goes on. Suddenly car-pooling wouldn't seem such an irritating idea, after all, we can't live without good clean water -- or air, or for that matter good old Southern cornbread. If this corn ethanol takes off, just how costly will a pound of corn meal be?
If we're going to create a whole new dynamic in America's food supply in order to mitigate our dependence on oil, let's pick something that would have a healthy impact on the American diet. After all, we are the most obese country in the world -- let's fix that problem and at the same time create an alternative bio-fuel. With those joint goals, sugar cane becomes the ultimate ethanol crop with enormous positive consequences for the health of America. No doubt with less sugar in our diet we could breathe a whole lot more of that fouled country air -- our immune systems would be much stronger without all that sugar, and we'd be a lot thinner and could more easily fit in little bitty cars that run on bio-fuel.

Carbon Monoxide - Future Source of Ethanol?
If the new technology discussed below proves to be a viable approach to Ethanol production one day, it will surely improve the air quality of the USA due to captured and utilized carbon monoxide emissions, and perhaps take some pressure off the demand and thus price of corn. A continued increase in the price of corn effects not only the cost of gains in a feedlot and on the family farm, but also is having 'trickle down' ramifications throughout our economy that will become increasingly apparent to the American consumer.
An alternative for the family farm is to raise their cattle on grass and legumes, rather than depend on corn and it's byproducts, and that requires moderate-framed easy-fattening grass genetics.

New Zealand company converts carbon monoxide to ethanol
AUCKLAND, New Zealand, April 24 /PRNewswire/ ‒LanzaTech, the leader in technology using bacterial fermentation to convert carbon monoxide into ethanol, officially announced April 24 that it has secured US$3.5M in Series A funding, led by Khosla Ventures and supported by two existing New Zealand based investors.
This funding will support further technology development, establishing a pilot plant, engineering work to prepare for commercial-scale ethanol production and positions the company to raise significant capital in the near future. This technology could produce 50 billion gallons of ethanol from the world's steel mills alone, turning the liability of carbon emissions into valuable fuels worth over $50 billion per year at very low costs and adding substantial value to the steel industry.
The technology will also be a key contributor to the cellulosic biofuels business as it can convert syngas produced through gasification into ethanol.
"We have proven in our laboratories that the carbon monoxide in industrial waste gases such as those generated during steel manufacture can be processed by bacterial fermentation to produce ethanol. Garnering the financial and strategic support of Khosla Ventures is a significant validation of our approach, and we welcome Khosla Ventures Chief Scientific Officer, Dr. Doug Cameron, to our Board of Directors," said Dr. Sean Simpson, Chief Scientist and Founder of LanzaTech.
Vinod Khosla commented, "Technology to produce fuel ethanol from waste material, such as the carbon monoxide produced in steel manufacture and other industries, makes use of a low cost and plentiful point source carbon feedstock. The opportunity is a large one as carbon monoxide is a significant byproduct of steel manufacture. LanzaTech has developed technology and a process to cost-effectively convert carbon monoxide into ethanol -- this ground breaking technology provides the tools to address the challenge of reducing emissions and turns waste into a valuable product, while developing new businesses based on innovative science."
LanzaTech was co-founded in 2005 by Dr. Richard Forster and Dr. Sean Simpson, who both have many years of experience in biotechnology and biofuels. The company is aggressively pursuing the development of advanced gas to ethanol technologies based on work developed in its laboratories in Auckland, New Zealand. As part of its two-pronged strategy of technology development and deployment, LanzaTech has sought international patent protection for its ethanol production process and is forming partnerships to commercialize its technologies and processes.
Khosla Ventures offers venture assistance, strategic advice and capital to entrepreneurs. The firm helps entrepreneurs extend the potential of their ideas in both traditional venture areas like the Internet, computing, mobile, and silicon technology arenas but also supports breakthrough scientific work in clean technology areas such as bio-refineries for energy and bioplastics, solar, battery and other environmentally friendly technologies.

Spring and Newborn British White Calves in East Texas
Well, it is time I got back to blogging and sharing what's happening here at the ranch with my herd. (and to Taylor and Alana, all the photos can be clicked on and enlarged. . . and of course you both are so up on things, you no doubt realize that!) It's Springtime, and it is looking to be a beautiful Spring here in East Texas. We did have a quite odd Easter, with Easter morning requiring one to hide Easter eggs beneath a thick layer of sleet from the night before, we even had lots of snowflakes the evening before! Butt, Taylor's Mom, Catheryne, hid some candy filled eggs for Taylor and Alana in the house late morning and they had quite a hunt.
My niece, Taylor, and her friend, Alana, were thrilled with the change in the weather and the snow and sleet, having nothing on their minds but the uniqueness of the experience -- which we all should, how boring if the days and months of the seasons of the year were always the same. I realize it creates difficulties for many, these odd turns in the weather, but all the same it is our life, and without these seasonal changes and oddities . . . I don't know, I think I would miss them. I spent most of the winter indoors on essentially numbers and book work, and felt like I'd missed the winter;this last bit of winter suddenly appearing in the Spring made me happy, and certainly ready to let it go and get on with the Spring. Taylor and her good friend, Alana, really enjoyed the weekend 'joy-riding' as they termed it in my new Ranger, but judging from the quite apparent track through the center of my best back pasture that ends with a few berms that lead down to a ravine, (no doubt quite fun to roar through) they will not be having free reign with the Ranger in the coming seasons until they realize the damage they can do.
Besides buzzing around in the Ranger, the girls took turns trying to blow an old horn made from a cow's horn, or maybe a bull, who really knows! The photo above is of Alana giving it one last try on the Eve of Easter with the weather turning very windy and cold. The cows were coming up for a look and a listen, not accustomed to hearing the quite odd sounds Alana managed to make with the old horn. The next picture is of Taylor, suited up in my coveralls again (and yes, I'd dearly love to find some feminine coveralls from someone somewhere....clothing manufacturers please listen!) We newby cowgirls would like to have a more ....feminine and better fitting coverall for cold days working the cows! And even some very light weight ones for the summer....
Note how Taylor is able to approach this two day old calf without it's dam, who is just to the right in the photo, having not any problem with Taylor's approach and touching of the newborn, beyond being . . .watchful. That's what is so wonderful about this breed, their trusting and docile nature. This particular cow is actually a British White half blood, her dam was an excellent registered black Angus cow who would have done much more than appear to glare a bit at Taylor's approach or touching of her calf -- her Angus dam would have knocked you down.
My newborn calves weathered the cold sleet quite well and all were fine on Easter morning, with one cow, J.West's Madison, calving late that morning just in time for Taylor and Alana to see the newborn bull's birth before they left to spend the rest of that special day with their families. We didn't have the camera going, one of those moments when running back to the house seemed the wrong thing to do, we might all miss the big event, but the girls were able to watch from a close distance, and were quite enthralled to witness their first complete birthing of a calf, and Madison the cow was quite fine with her audience.
The following photo is of J.West's Wanda Mae, an outstanding heifer, who found herself a cozy spot in native clover and wasn't much interested in moving with the rest of the herd, including her mama, through this pasture to the next pasture this past week. I think the heavy native clover growth must surely be due to all the rain this area has had the past several months, and perhaps as well to my haying of the cattle on this once red muddy hilltop these past few years, adding much needed organic matter to the soil -- as well as scraping top soil from other areas and spreading it somewhat thinly across the surface a few years back. The combination of those efforts and this very wet Spring seems to have paid off.
If I could post a video or photo that allowed you to smell the sweet scent of this pasture of clover I would. It has been quite a beautiful early Spring pasture, buzzing with the hum of bees and smelling like Spring. It's all the more amazing to me knowing that it was nothing more than a barren red hill top a short 4 years ago. The prior owner had scraped this hilltop completely down deep into the clay soil that lies beneath the sandy layers of usually about 3 to 4 feet. It has taken much time to bring this pasture back to productivity, and this Spring has seen it at it's best for certain.
