Abstract

A series of 4 trials were conducted over 2 years, using suckled beef cows and virgin heifers, to compare the effectiveness of an estrus synchronization program with fixed time AI, utilizing a progesterone releasing intravaginal device (CIDR-B®, InterAg, New Zealand), with other controlled breeding strategies.
