Late May and early June are prime bull turnout times in the beef business, so the final check needs to be done now to make sure every bull is ready to go.
The beef business depends on buying fertile, productive bulls that pass on the desired genetics to their offspring and meet the consumers' demand for beef.
This spring, many producers have purchased a bull that is in the $3,000 to $5,000 range. It's a good investment, but good investments need to be cared for and maintained properly. One of the keys to a successful breeding season is a bull that breeds cows. That seems like such a logical thought, but it is not.
There are three major considerations when evaluating bulls as the breeding season approaches. The first and the simplest is the breeding soundness exam.
The exam tends to get the most publicity, and constant reminders are given to have the bulls fertility tested. These tests need to be done six to eight weeks prior to bull turnout because the bulls are expected to be producing viable sperm in advance of the breeding season.
If for some reason a bull fails the breeding soundness exam, the bull should be re-evaluated now. If he fails again, the bull needs to be culled. Keep in mind that many yearling bulls are fertility tested prior to selling and are screened adequately at sale time. However, if the opportunity presents itself, re- evaluating the new bulls when the older bulls are evaluated certainly does not compromise management.
Now the second point of consideration: Although often part of the breeding soundness exam, general bull thriftiness and structure need to be evaluated. A bull often may cover up a weakness when being worked with other bulls, so unsoundness may be overlooked. The back legs and hips are the working machines that allow a bull to breed. Any defect needs to be evaluated very critically.
Once out on the pasture, the opportunity to evaluate adequately, along with the added difficulty of gathering the bulls, makes second decisions very difficult.
Bulls that have lost condition prior to bull turnout certainly are candidates for poor fertility. As with the cows, a condition score of 5 or 6 means the bull is in good breeding shape. However, losing condition prior to breeding is not advisable. Much like breeding soundness exams, bull nutrition needs to be correct two months before bull turnout because making changes prior to breeding is ill-advised.
The third important criterion is bull behavior, or aggressiveness and breeding desire. Some bulls may be too aggressive and even place the producer and ranch hands in the pecking order as they work to dominate all living things. Although certainly ready to be turned out, these bulls should be noted and politely excused when an opportunity comes to sell them.
