Abstract

Bulls vary greatly in their reproductive capabilities. This variation can have a marked effect on overall pregnancy rates as well as on the time period required for pregnancies to be achieved. This, in turn, affects weaning weights. Apart from disease, injury, or physical obstacles in the breeding pasture, this variation is due to one or more of three factors: a) semen quality and/or quantity; b) sex-drive (libido) and mating ability; and c) social interactions between animals.
