Regulation of beef heifer productivity by dietary energy and prepubertal administration of bovine somatotropin

Weanling heifer calves (n = 452) grazed tall fescue pastures and were fed a high (H) or low (L) amount of corn supplement during a postweaning treatment period of 136 d. Postweaning gain of heifers receiving L and H was.43 and.62 kg/d, respectively. Heifers receiving H were heavier, and had more fat thickness at yearling. More H heifers were pubertal before the breeding season. Mean milk production was greater for H heifers and resulted in heavier calves.
