摘要

In the U.S.,live beef production is segmented into cow‐calf,stocker/backgrounder,and feedlot phases.Efficiency in beef production systems depends on proper relationships between each of these segments.Since milk yield accounts for over 50% of the variation in calf weaning weight,cow‐calf producers depend on higher milk production in their cow herds to produce calves that are heavier at weaning.Unfortunately,higher levels of milk yield in the cow and the corresponding greater milk consumption by calves during the preweaning phase may be associated with lower growth performance in the stocker/ backgrounder production phase.The objective of this research was to evaluate the effects of preweaning milk yield of the cow, postweaning management of the calf,and sire breed of the calf on postweaning ADG during the stocker/backgrounding phase.
