Beef cattle producers, similar to other segments of the agriculture economy, are facing declining prices and much tighter profit margins.  In a recent OSU Extension Beef Cattle Letter,

Michelle Arnold, DVM, Ruminant Extension Veterinarian, at the University of Kentucky wrote a good article outlining sound culling decisions as part of financial management.  Here are excerpts from that article:

Every year, the cow-calf producer needs to critically evaluate each animal in the herd and decide if the cow is paying her upkeep.  Open cows (those that are not pregnant) at the end of breeding season obviously are the top of the cull list. With variable costs running $400-$500 per year per head and an additional $100-$300 in fixed costs, keeping open cows is a financial black hole.  Other variables such as structural soundness, body condition score; age, performance, and disposition are vital components in developing a culling order specifically for your farm.  To begin, it is best to think about which cow(s) in the herd has the least chance of being productive in the long term or is farthest away from being productive.  The following is a list of factors to consider when deciding who to cull this year.

  • Disposition – A cow’s attitude is an important consideration in any cattle operation. Bad behavior has both a genetic component and is also learned by calves at an early age. Mean cattle are dangerous to people, damage facilities, tear up fences and make gathering and working cattle a nightmare. Remember a good cow can be protective without being dangerous and destructive.
  • Pregnancy Status – A cow should produce a calf at least once a year and the sale of that calf needs to pay her way. Diagnosing a cow as “open” (not pregnant) is as simple as veterinarian palpating for pregnancy at least 40 days after breeding or removing the bull. A simple, inexpensive blood test can also be used 28 days post-breeding to determine pregnancy status. If many cows are found open at pregnancy check, work with your veterinarian to determine if reproductive disease, poor nutrition, bull infertility or inability was the cause.
  • Structural Soundness – Bad hooves or claws, lameness due to hip/knee injury, eye problems, and poor udder conformation are all examples of structural problems that adversely affect performance.  Good feet and legs are essential for weight maintenance, breeding, calving, self-defense, and raising a calf. The udder should be firmly attached with a level floor and high enough that newborn calves can easily find and latch onto teats. Cows with blind or light quarters, funnel or balloon shaped teats, or any history of mastitis are strong candidates for culling.
  • Cows with chronic conditions that will not improve such as progressive weight loss, early cases of cancer eye, repeated episodes of vaginal prolapse during pregnancy and extreme sensitivity to the effects of fescue toxicosis should be removed from the herd as soon as the calf is weaned. Cows with confirmed disease conditions such as Johnes disease, bovine lymphoma, or advanced cancer eye should not be returned to a commercial market.
  • Age – Cows are considered most productive between 4-9 years of age. Cows with badly worn or missing teeth will have a hard time maintaining body condition.
  • Poor Performance – Record keeping is an invaluable tool for evaluating performance. Readable visual tags on both the cow and calf allow you to match calf sale weights to the dams and identification of cows that did not produce a calf. Inferior genetics and poor milk production produce lightweight calves that do no grow well.
  • Phenotype – These are cows that do not “fit” the herd because of external features such as unusual breed, size, muscling and color. These challenges may be overcome to some degree by choice of sire to balance out the unwanted traits. Remember that buyers of commercial calves look for uniformity in color, weight, and frame in a set of calves.

Since 20% of gross receipts in a typical cow-calf operation come from the sale of cull animals, pay attention to price seasonality and body condition score before sending these animals to market. Prices are highest in spring and lowest in late fall/early winter when spring born calves are weaned & culls sent to market. Adding weight and body condition to culls is an opportunity to increase profitability but can be expensive. Work with a nutritionist to come up with realistic cost projections before feeding cull cattle for a long period of time.

Functionality leads to longevity and improved efficiency. By retaining more young cows in the herd, you can decrease the number of replacement heifers needed and cull cows that are only marginally profitable. Young cows also increase in value as they mature because the body weight of the cow and her calf’s weaning weight will continue to increase from 2-5 years of age. Longevity may also be improved through crossbreeding because hybrid vigor adds essentially 1.3 years of productivity or one more calf per cow.

In summary, a herd of easy-keeping, efficient cows is possible through rigorous culling and careful selection of replacements.  Match your genetics to your management and environment for maximum efficiency, longevity, and ultimately, maximum enjoyment of cattle production.
