Identifying non-pregnant cows and cows bred late in the season allows them to be removed from the herd to avoid winter feed costs. The remaining cows in the herd will be the most profitable. Pregnancy exams are usually given at weaning time when the cows are gathered and worked. At this time, examine condition of udder, feet, teeth, and eyes and abnormalities of the reproductive tract. Cows may also be given annual vaccinations and treated for lice.
Some producers sell cull cows immediately after weaning.
However, if cows are thin or young, a short feeding period on high energy feeds may be profitable. A marketing plan is advisable for the sale of cull cows since they contribute a significant portion to total gross income of a cow herd. Embryonic losses or abortions can occur at any stage of gestation. An attempt to accurately diagnose the cause of abortions should be made by a veterinarian working with the support of a Diagnostic Laboratory to help prevent further losses. A complete vaccination program should be designed with the help of the local veterinarian.
