Recombinant bovine somatotropin improves growth performance in finishing beef steers.
The objectives of this study were to determine the efficacy of various doses of rbST on ADG and feed efficiency (FE) and to describe carcass composition changes in finishing beef steers. In Exp. 1, 96 crossbred beef steers (393 kg) received daily i.m. injections of buffer or 33, 100, or 300 micrograms/kg of BW of rbST (0ST, 33ST, 100ST, 300ST). In Exp. 2, 200 crossbred beef steers (417 kg) rece...

15 صفحه اولPerformance, clinical chemistry, and carcass responses of finishing lambs to formulated sometribove (methionyl bovine somatotropin).
Formulated zinc methionyl bST (sometribove, 50, 100, or 150 mg) was administered as a single treatment once every 2 wk or as two equal treatments once/week to evaluate the efficacy of prolonged release delivery of bovine somatotropin (bST) in finishing lambs. Feed conversion during the 6-wk treatment period was improved 9 and 19% in lambs that received treatments once and twice/2 wk, respective...
متن کاملEffect of Lysine to Digestible Energy Ratio on Growth Performance and Carcass Characteristics in Finishing Pigs
This experiment was performed to investigate the effects of lysine (Lys) to DE ratio on growth performance, and carcass characterics in finishing barrows. Ninety six cross-bred finishing barrows ((Landrace×Yorkshire) ×Duroc, average BW 58.25±0.48 kg) were assigned as a randomized complete block design by 2 energy levels and 4 Lys:DE ratios on the basis of BW to one of 8 treatments with 3 replic...
