Optimum beef cow size for production resources in north Arkansas


, : Optimum beef cow size for production resources in north Arkansas. Special Report Agricutural Experiment Station, Division of Agriculture, University of Arkansas ( 151): 43-47

Brody's growth model was fitted to body weight data on 284 American Angus and 254 Hereford cows. Lifetime productivity of cows was measured as number of yr in the herd, number of calves born, av. birth weight of calves, number of calves weaned, weaning weight of calves, total weaning weight per yr, total amount of beef produced, and lifetime food conversion efficiency.
