Calf Birth Weight - Actual versus Tape Measure

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.

Organic Consumers Really Ought to Keep Reading Those Labels!

***What's interesting here is that the 'booted' USDA organic ingredients. . . are not organic.

What's really incomprehensible is the concluding statement below that the ". . . USDA is revising its National List to include the 38 (nonorganic!) ingredients. If all goes as planned, processors would be able to use them when an organic counterpart wasn't available commercially."

Legal/Regulatory News
USDA gives the boot to certain organic ingredients

By John Gregerson on 6/18/2007 for Meatingplace.com


As a result of a new USDA rule, organic products containing certain non-organic minor ingredients are in non-compliance with organic certification — at least for now.

The National Organic Program regulation clarifies that only ingredients appearing in the USDA's National List of Allowed and Prohibited Substances are suitable for organic product — bad news for 38 non-organic ingredients, including colors, starches and oils, routinely used in organic foods as a result of misinterpretation of National List regulations.

The ban may be temporary. USDA is revising its National List to include the 38 ingredients. If all goes as planned, processors would be able to use them when an organic counterpart wasn't available commercially.

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.
Pictured here is a British White grassfed yearling bull, grassfed from conception onwards.


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.

British White Cattle - Let's Keep "Chasing" Pursuit of Hard Data to Present to the Beef Industry


As British White breeders we daily face lack of acceptance in the mainstream Beef Industry as our cattle are white hided and haven't been the subject of University studies (any breeder or patron out there that might be interested in donating cattle or semen for MARC studies or University studies, please do contact the British White Cattle Association of America at 903-965-7718). We are likely perceived by some in the beef industry as "chasing" a goal that is unwanted or unnecessary as there are some closed-minded industry perceptions about what works and what doesn't when it comes to established beef breeds and beef production, and know-it-alls such as described in the article excerpt below, think they. . . know it all.

As British White breeders we know we have cattle with excellent maternal traits, fertility, hardiness in wide ranging climates, calving life longevity upwards of twenty years, well set udders that withstand the rigors of years of suckling calves without "falling down", excellent carcass quality, genectically gentle dispositions, and more. But, we do need to pursue or "chase" documenting those outstanding qualities through some or all of the following -- Conscientious recording of growth trait data such as weaning weights and yearling weights; establishing Ultrasound Guidelines for the breed and pursuing the capture of yearling bull and heifer carcass ultrasound data by certified technicians; adding to the growing pool of DNA data for the currently identified markers for Marbling and Tenderness; establishing an annual Feedlot test for crossbred and purebred feeder steers and heifers; seeking out Bull Performance tests in our local areas for our bull candidates.

The following is an excerpt from "CAB Cattle Update: The “C” word". Click the Title link above for the text of the whole article.

". . . It’s usually better to lead than chase cattle, but one calorie-counting authority estimates a moderate walk in non-strenuous cattle chasing burns 238 calories per hour for a 150-pound person. At that rate, it would take more than three hours to walk off a Big Mac.

You may be thinking of another idiom: cut to the chase, or get to the point.

Some beef industry pundits proclaim ideal pathways for all logical producers. Dissenters are deluded and must be “chasing” something.

You can sense the judgment and condemnation in the cliché warning, “don’t chase single-trait selection.” It’s such an obvious no-no that the only surprise is that we keep seeing the warning. There is usually an agenda, such as to imply that if you so much as include some popular trait, you are off on a rabbit trail. If you know the phrase at all, you know it’s like saying, “don’t chase your tail.”

Some intense cattlemen lash out with the “c” word. They may include their goals and aspirations, which never include so much as a stray glance at what they own as a senseless pursuit. However, those who see things differently are condescendingly lamented as chasing an illusive and impractical dream.

The most chased-after end seems to be genetic selection that would add value to the beef we sell to consumers. One might as well chase ping-pong balls or a cure for cancer. Critics include the range of those who see any attention to post-weaning traits as silly, to those who see it as a noble, if impossible dream.

When the rhetoric starts flying, a critic may deplore “chasing” something or other. He will usually balance that by pointing out the further errors of “ignoring” and “sacrificing” other things. The implication is that those slighted pursuits are at least as worthy as that being chased after, but the chaser is too blind to see.

It all boils down to bias in the critic. Look at their cattle, their field of study, perhaps their life’s work. They may not realize their bias or the condescending nature of their chase to enlighten others. Or, they could be using loaded words in a calculated manner to sell something. . ."<

British White Cattle - Gentle, Grassfed Cattle Genetics in Southeast Texas



The British White Cattle Breed has much to offer the cattle producer in terms of both economics and genuine pleasure in the care-taking of this gentle, beautiful, ancient and immortalized breed. British White cattle embody all traits of economic importance to cattle producers -- excellent fertility, milkiness, hardiness to disease, calving ease, maternal instincts, and a long-lived calving life. Their white hides give them superior heat tolerance and their black hooves are sound and sturdy.

Perhaps the most distinguishing economic trait of the British White cattle breed is their unusually curious and docile nature, well represented by the girls pictured just below who had to have a look at what I was doing sitting on the ground in their space. Visitors to British White herds often comment that their calm demeanor is surely due to the "time we must spend with them". Senorita Lisa, Lucy Rae, and Donna DarlingBut, breeders of this very special, uniquely beautiful, ancient breed know different. Their gentleness begins before birth -- it is inherent in their genetic make-up. From almost the day of a calf's birth, breeders of British White cattle can many times judge the likely temperament of their calves, and the range is generally from at a minimum no flight zone to the maximum temperament of one so gentle and curious they come to you in the pasture.

How does a gentle nature translate into one of economic importance to a cattle producer? Every scientific research report that one comes upon studying the relationship between docile calves in the feedlot to carcass tenderness, results in the conclusion that the calmer the feeder calf the more tender the carcass as in the report found at this TAMU link . One day it will be realized that when a commercial cattleman puts a British White Bull on his herd his calves are calmer, their growth is superior, and their carcass brings to them a premium over Black Angus, a highly volatile breed by comparison. J. West's Polly, a registered Halfblood British White heiferPictured to the left is a half blood female who was sired by a British White bull and whose dam is a commercial black cow who won't let you approach at all. This heifer on the other hand, is much calmer with a flight zone of a foot or less, and will sometimes let you pat her on the head. An important point to be made here is that in contrast to their generally docile nature with humans, they will both singly and as a group make swift and effective attack on predators such as coyotes and buzzards that threaten their calves; or even your blind, geriatric dog if he picks his way across a cattle guard in search of you and instead walks straight into a calf newly born to a heifer. They seem to have the ability to better judge what is a threat to them and their youngsters above that of other breeds; and humans are pretty much not perceived as threatening. British White herds don't scatter on the approach of strange humans, most will even remain lying down and disinterested.

Of great economic importance to cattle producers is the actual carcass quality coming out of the Feedlot. Besides the established correlation between docility and carcass tenderness mentioned above -- today there is DNA testing readily available to help identify animals that will most likely produce calves with superior carcass traits for tenderness and marbling. The DNA testing accomplished to date on approximately 80% of the herd of J. West Cattle Co. reflects the following:
bullet 100% are carriers of the T1/Calpistatin gene for Carcass Tenderness, and of those . . .
*** 64% are Homozygous for T1 (have two copies of the T1 gene, and thus will always pass on at a minimum ONE copy of the gene to their calves)
*** 9% are Heterozygous for the T2 Tenderness gene.
*** 80% are carriers of the T3/Calpain gene for Carcass Tenderness, and of those . . .
*** 27% are Homozygous for the T3/Calpain Tenderness gene.
*** 45% of this British White herd carries at a minimum one copy of the Carcass Marbling gene identified as QG1 with GeneStar, and of those . . .
*** 8% are Homozygous for the QG1 Carcass Marbling gene,
*** 11% are Heterozygous for the QG3 Carcass Marbling gene,
*** 49% are carriers of the QG4 Carcass Marbling gene, and of those . . .
*** 41% are Heterozygous for the QG4, and 8% are Homozygous for the QG4 Marbling gene.

As DNA testing and planned breeding progresses over the next few years to intensify these genetic traits, the results are expected to continue to be superior and to further establish British White cattle as THE Beef Breed of the Future for genetic Tenderness combined with genetic Docility -- a combination no other breed can match -- and a combination that the Commercial Feedlot operator will not ignore and will demand from commercial cattleman.

Besides the important economic traits of the British White breed, there is another trait that is unmatched by any other breed -- their extraordinarily striking beauty, and of course I realize that is a matter of personal opinion. British White Cattle are predominantly white with black points. Often, there are scattered spots of black along their sides, and typically this is accompanied by very strong color points about the nose, eyes, ears, teats, and lower front legs, which are the basic black color points expected in the breed. Their unique beauty is always a source of comment by visitors, as is their calm demeanor -- both traits that most likely inspired and perpetuated ancient Celtic lore and legend that immortalized the British White 'milk white cow' and predate the written word. Much of the ancient lore and legend makes reference to the occurrence of the red-pointed calf that is born in otherwise black-pointed herds; this occurs in British White herds today as in ancient days and is always one of surprise and remark. As well, a small percentage of calves are born with a line-backed pattern, and this has occurred throughout both the horned and polled white park cattle's documented history. See Breed History for additional information on their ancient history in the British Isles.
