…several years ago I started using 1,200 pounds as a weight when balancing rations for the average cow. That weight may need to be increased now…
Yep, the last time I heard anything about it, the BLM and uSFS are considering going to a 1,400 lb AU. — jtl, 419
“In the last few years it is because the cow herd owners all-of-a-sudden realized they had some cows that weighed 1,600 to 2,000 pounds when they sold them. That began a trend toward moderating cow size,” Cole said.
There was a time, according to Cole, when southwest Missouri had a lot of small frame cows that weighed under 1,000 pounds. Those were ultimately eliminated through genetic selection. Frame size was stressed, along with heavier 365-day weight and mature cow size went up to 1,200-1,400 pounds.
“When discussing cow size in this area we do not know exactly how big the average cow is. I did know several years ago I started using 1,200 pounds as a weight when balancing rations for the average cow. That weight may need to be increased now,” Cole said.
“During the tours, invariably someone would ask the rancher what their average cow weighed. The lowest reply was 1,300 pounds. Most were in the 1,400- to 1,500-pound range, and one Charolais breeder said 1,600 to 1,800 pounds,” Cole said.
The 70-head beef cow herd at the Southwest Research Center near Mt. Vernon was recently scored by Cole and some other MU Extension specialists. Weights were caught on all of the cows that will begin calving in early September.
According to Cole, the average weight of the high-percentage Angus x Simmental cows was 1,386 pounds. Their ages varied form three years to one 14-year-old. Weights ranged from 1,760 down to 1,050 pounds. The oldest cows, nine years plus, averaged 1,553 pounds, the next age group with a 1,493-pound average were the 7-year-olds.
“The downsizing of beef cow weights and frame is viewed as a way to improve cow efficiency. However, some feed studies using the Grow Safe system raise questions,” Cole said. “The bottom line seems that there are very efficient large cows and some inefficient small cows. Researchers will continue to study that important trait and incorporate it into genetic predictions via genomics and expected progeny differences.”
Cow size has been equated to the desired steer market weight at slaughter. If the packer did not discount and seemed to want an 875-pound carcass (which would be a 1,400-pound live animal), then producers would try to have a mature cow weighing around 1,400 pounds.
“Optimum cow size has been and will continue to be an elusive target. Each geographical region will vary in what size is favored. Each cattle raiser needs to do some record keeping to determine what optimum for their operation is,” Cole said.
Cole advises producers to keep an eye on local feeder cattle markets, slaughter cattle price trends, breed association sire summaries and the cows in their herd. All of these can help decide what is the right cow size for an individual’s farm or ranch.

Murray N. Rothbard was the father of what some call Radical Libertarianism or Anarcho-Capitalism which Hans-Hermann Hoppe described as “Rothbard’s unique contribution to the rediscovery of property and property rights as the common foundation of both economics and political philosophy, and the systematic reconstruction and conceptual integration of modern, marginalist economics and natural-law political philosophy into a unified moral science: libertarianism.”
This book applies the principles of this “unified moral science” to environmental and natural resource management issues.
The book started out life as an assigned reading list for a university level course entitled Environmental and Natural Resource Economics: The Austrian View.
As I began to prepare to teach the course, I quickly saw that there was a plethora of textbooks suitable for universal level courses dealing with environmental and natural resource economics. The only problem was that they were all based in mainstream neo-classical (or Keynesian) theory. I could find no single collection of material comprising a comprehensive treatment of environmental and natural resource economics based on Austrian Economic Theory.
However, I was able to find a large number of essays, monographs, papers delivered at professional meetings and published from a multitude of sources. This book is the result. It is composed of a collection of research reports and essays by reputable scientists, economists, and legal experts as well as private property and free market activists.
The book is organized into seven parts: I. Environmentalism: The New State Religion; II. The New State Religion Debunked; III. Introduction to Environmental and Natural Resource Economics; IV. Interventionism: Law and Regulation; V. Pollution and Recycling; VI. Property Rights: Planning, Zoning and Eminent Domain; and VII. Free Market Conservation. It also includes an elaborate Bibliography, References and Recommended Reading section including an extensive Annotated Bibliography of related and works on the subject.
The intellectual level of the individual works ranges from quite scholarly to informed editorial opinion.
