چکیده

quality semen can be produced ulls of any age, but recovery in 3-6 months was found in nearly half of such bulls that could be retested. Semen samples were obtained from 460 bulls 15-24 months of age, from 53 bulls 3 6 years of age, and from 12 bulls 2-6 years of age, used for breeding. The test on the first two groups is recorded in the table in the first and second columns. Of the 460 young bulls, 37-about 8'i/c-produced semen that would indiroductive efficiency of 30% or
