Abstract
Part I of this two-part presentation discussed fertility assessment an d the economics of using yearling bulls to breed beef cows. This part discusses genetic selection and the management of yearling bulls in th e breeding pasture. Use of yearling bulls can accelerate genetic impro vement. In particular, bulls can be selected to promote calving ease. Well-grown, 14- to 15-month-old bulls can each successfully settle at least 25 cows during a confined breeding period. Young bulls with high libido can withstand considerably higher mating loads. Bulls in multi ple-sire pastures tend to mount a larger percentage of estrous females . Also, multiple sires provide some protection against production loss in the event of illness, lameness, or penile injury.
