Effect of nutrient intake on pigs treated with porcine somatotropin

An experiment was conducted to develop a technique for hyperalimentation of growing swine and to evaluate the effect of hyperalimentation on feedlot performance and carcass criteria. To allow for infusion of feed into the stomach, a cannula was implanted. The implantation of a cannula into the greater curvature of the stomach was well tolerated by these animals. Hyperalimentation to 120% of the cannulated, ad libitum fed control animals depressed feed efficiency (gain:feed). Hyperalimentation did not affect protein growth of the carcass, but did tend to increase fat thickness measured at the 10th rib, last rib, last lumbar vertebrae, as well as the P2 site.
