I had a discussion last week concerning selling older cows and replacing them with bred heifers. This is an important decision for most cow-calf producers including myself as I have bred heifers for sale and I have some older cows whose useful life in the breeding herd is extremely short. Thus, there are multiple questions to answer.
The first is if and when a mature female should be marketed. The second is if she should be replaced with a younger breeding female now or at some later date.
From the market price perspective, it is extremely important to compare the value of the mature female with the value of replacing her. As an example, boning utility cows in Tennessee had an average price of $143.50 per hundredweight last week and had an average weight of 1,210 pounds, which results in a value of $1,736 per head.
The decision at this point is to develop and breed a female or to purchase a bred female. Bred females are guaranteed bred and will generate revenue more quickly which makes them more valuable than one to be developed and bred.
