Following last week’s discussion on slaughter cow prices, a question was asked concerning the different classes of slaughter cows. Slaughter cow grades are based on fat cover. A breaking utility cow is in a body condition score (BCS) of 7-9 which means she is fat/obese. A boning utility cow is in a BCS of 4-6. Most producers will want their breeding herd in a 5-6 BCS. Lean/light are in a BCS of 1-3, which means they are extremely thin.
This is a very generalized explanation of slaughter cow grades, and there are more specifics that determine the final price. For instance, if an animal is expected to produce more lean beef than another animal relative to their total weight then it will receive a higher price. Some things to look for include looking at the fat over the ribs, hooks and pins. If the ribs are well covered then it is good to look at the fat cover on the hooks and pins to get an idea of the quality of animal.
In today’s market, there is a strong demand for lean grinding beef, which is what is supporting slaughter cow prices.
