Abstract

The effect of feeding complexed trace minerals to cows on postpartum resumption of ovarian activity was evaluated in nine trials. In these trials, cows fed complexed trace minerals had fewer days to postpartum ovarian activity as noted by fewer days to first estrus and luteal activity, reduced need for progesterone-secreting vaginal implants (CIDR) and increased percentage of cows bred by artificial insemination (AI) and exhibiting ovarian structures at 45 days postpartum.
