Calving date affects cost and timing of production events. Because of the polyestrous nature of beef females, producers can choose a calving date that fits their production system and geographic region. Any time an entire production system is conside

Reproductive performance of heifers offered ad libitum or restricted access to feed for a one hundred forty-day period after weaning1

Autor: Thomas W. Geary, Michael D. MacNeil, R. C. Waterman, E. E. Grings, Andrew J. Roberts

Publikováno v: Journal of Animal Science. 87:3043-3052

Reproductive performance was evaluated in composite heifers born over a 3-yr period that were randomly assigned to control (fed to appetite; n = 205) or restricted (fed at 80% of that consumed by controls adjusted to a common BW basis; n = 192) feedi
