Are your cows pets or paychecks?

How tough are you on your cows? I have worked with people that are on both ends of the spectrum. Some people keep any cow that weans a calf, even if it only weighs about 300 pounds but I also have worked with people that say that if a cow's calf is killed on the road, the cow is culled for it was her fault for having the calf there to begin with. Now this one is an extreme. It comes at the cost of a higher replacement rate and requires a refined management and genetic program, a balanced feed resource, and an economically viable operation with dedicated and well-educated manager. This higher culling rate allows the beef herd to make genetic progress at a faster pace in the areas of convenience and economically important traits.

Genetic progress is realized when replacement rates account for cows with bad dispositions, poor mothering ability, marginal or inadequate bags, bad eyes, runt raisers, and those that don’t hold their flesh or are lacking in conformation. Professionals encourage a limited calving interval of 45-60 days as well as elevated feedlot and rail performance. This sets the bar unrealistically high especially for our environment and most certainly during drought years. If all the above mentioned criteria were included in a culling program, a replacement rate of 20% or higher would be required to maintain carrying capacity.

The best managed and most profitable cow/calf operations generally subscribe to selling all open and dry pregnant cows. If a cow weans one calf and has another one on the way, she herself becomes the paycheck. Generally a 10-15% replacement rate is required to maintain stocking rates when following this “three-in-one package” culling criteria.

All cows are not created equal, which is self-evident by high fallout rates. Consequently the quality of replacement heifers retained or purchased should be far superior to the market ready cows (culls) they are replacing. Improving efficiency of a cow herd through culling is effective to a point, however, only if prudent bull selection is used to sire replacements. It’s unrealistic to expect different results when continuing to follow the same failed management and genetic program. Management and/or available feed resources influence economically important and convenience traits. If a large percentage of cows often fall out of your program, consider a change in genetics and management or try adding additional resources to your ranch.

Higher replacement rates capitalize on the principle of the economic unit which maintains that it takes the same amount of annual inputs to feed a good one as it does a marginal or poor producing cow. The average annual cow carrying costs, including fixed as well as variable costs, range from between $500 to $700 per head per year. Each animal on your operation should be viewed as an economic unit including pet cows. Each fall, in spite of poor performance or a history of producing outlier calves, many pet cows avoid the trip to the sale barn. It makes no economic sense why these cows are given a free pass based on sentiment, color pattern or simply an experience the owners had with the pet when it was a calf. None of these reasons justify fixed and variable carrying costs knowing a quality replacement animal could supersede the pet cow.

Counter to this discussion is the replacement strategy of retaining a higher percentage of heifers during poor market years and a lower percentage during high market years. The theory to this strategy is heifers retained during low market years will be producing calves during the high market years resulting in a more profitable cow herd over time. This strategy certainly has validity and should be considered in the decision making process. Keep in mind reduced heifer retention, even for a few years, requires lowering the bar on your culling protocol. Soon you have a lower quality aged cow herd. A constant infusion of quality replacements is required to hold your cow herd to a higher standard of production.

If your resources will only allow you to run 50 momma cows, make them 50 good ones. Maintain a zero tolerance retention strategy. Replace those poor producing economic units with cows that produce with the herd. First and foremost, remove the free loaders. Replacement rates are going to vary from farm to farm and from year to year. They are largely dependent on resources, management, goals and objectives, and the short and long term financial stability of a ranch. One thing is for sure, if cows have been given an adequate environment (such as health, reproduction, and nutrition), a “three-in-one package” should be demanded every year. If you want a great cow herd, a stringent and unforgiving culling program is essential and will require a high replacement rate.

Well done. We did a study back 20 years & found the largest owners of cows were retired military and in the SE US. There were no jobs after WWII so they stayed in sent money back to Dad to buy the 80-160 next door and ran Sadie, Bessie, etc on that land. The cows calf/cupon bought a TV, refrigerator, etc. Then the $50. an acre land became worth sever hundred for timber housing and they all lived happily after. Now equasion changed land is so high that the cattleman of today must really extract everything for survival.
