Know the cull cow grades before you sell

Many Southwest United States cow herds have been culled as much as possible.   Some culling of beef cows occurs in most herds every year.  If feed resources are available, a few producers may wish to market the culls after the first of the year for tax purposes. 

The Beef Audits have generally shown that cull cows, bulls, and cull dairy cows make up about 20% of the beef available for consumption in the United States. About half of this group (or 10% of the beef supply) comes from cull beef cows.  In a drought-plagued year, the percentage of some herds that are being culled goes even higher than the survey estimates of 20% of each cow herd. Whether we are culling because of drought or to improve the productivity of the herd, it is important to understand the values placed on cull cows intended for slaughter. 

The USDA market news service reports on four classes of cull cows. The four classes are divided primarily on fatness. The highest conditioned cull cows are reported as "Breakers". They usually are quite fleshy and generally have excellent dressing percentages. Body condition score 7 and above are required to be "Breakers".

The next class is a more moderate conditioned group of cows called "Boners" or "Boning Utility". These cows usually would fall in the body condition score grades of 5 to 7. Many well-nourished commercial beef cows would be graded "Boners".

The last two groups of cows as reported by the market news service are the "Leans" and "Lites". These cows are very thin (Body condition scores 1 - 4). They are in general expected to be lower in dressing percentage than the fleshier cows and are more easily bruised while being transported than are cows in better body condition. "Lites" are thin cows that are very small and would have very low hot carcass weights.

Leans and Lites are nearly always lower in price per pound than are the Boners and the Breakers. "Lites" often bring the lowest price per pound because the amount of saleable product is small, even though the overhead costs of slaughtering and processing are about the same as larger, fleshier cows.

Producers that sell cull cows should pay close attention to the market news reports about the price differentials of the cows in these classes. Cull cows that can be fed enough to gain body condition to improve from the Lean class to Boner class can gain weight and gain in value per pound at the same time.  Seldom, if ever, does this situation exist elsewhere in the beef business.  Last week, in Oklahoma City, the difference in "Leans" versus "Boners" was about 7 dollars per hundredweight in favor of the Boner cows.  Therefore, market your cull cows while still in good enough condition to fall in the Boner grade.  If cows are being culled while very thin, consider short term dry lot feeding or putting them on wheat pasture to take them up in weight and up in grade. This usually can be done in about 50 to 70 days with excellent feed efficiency. Rarely does it pay to feed enough to move the cow to "Breaker" class. There is very little if any price advantage of Breakers over Boners and cows lose feed efficiency if fed to that degree of fatness.
