Abstract

Managing variation in carcass weight and composition is an enormous challenge for the pig producer. A means of improving growth performance and reducing back fat is porcine exogenous somatotropin (pST) treatment. It is possible that this technology may also reduce variation in these important growth and carcass parameters. This study was conducted to provide data on the effect of sex and pST on variation in growth and carcass characteristics. Sixteen on-farm studies involving 1495 pigs were conducted in various states within Australia. On each farm, groups of pigs were randomly assigned within sex to one of 2 management regimes (control or pST regime). The control regime consisted of feeding..
