Administration of porcine somatotropin by sustained-release implant: growth, carcass, and sensory responses in crossbred white and genetically lean and obese boars and gilts.

Abstract excerpt

Previous studies have documented the efficacy of porcine somatotropin administered by sustained-release implant (pST-SR) in promoting rate and efficiency of lean growth in genetically lean and obese barrows and gilts. Herein, those studies have been extended to include contemporary crossbred boars and gilts. The study consisted of 18 treatment groups in an arrangement of three lines, two sexes, and three doses of...
