![]() ![]() One major limitation to a BSE is it is only valid for the test on the day of the test for the semen collection evaluated. The test has been proven to be very efficient for measuring bull fertility in the field. Failure to meet specific benchmarks for any of the factors results in a BSE failure. ![]() This process combines most of the components that contribute to fertility (scrotal size, sperm concentration, sperm morphology, and a physical exam of the reproductive organs) are all evaluated to develop final a score for a bull. The only objective method for measuring bull fertility is with a breeding soundness examination (BSE). Fertility in young bulls is a function of age, genetics, nutrition, and environment just to list a few factors.

To stack the odds in your favor you should select a bull with a breed average or lower birth weight and good calving ease. The first step in the selection of a bull is having one that will help the cow produce a live calf. The sale of market cows that did not get bred or lost a calf and the sale of market bulls will generate revenue but it also reduces the capital in the enterprise. When you consider the long term impact of the bull, you can never buy a bull that is too good.įor the beef cow-calf enterprise the sale of a live calf is the only true source of income. Following 3 generations of retained heifers, 87.5% of the genetic make-up of the females you return to the herd is the result of the last 3 bulls you purchased. If you maintain a closed herd, the genes entering the cow herd will come completely from the bulls you select. They often purchase feed, minerals, equipment, and other supplies that many times are promised to be the "best investment for the farm."
