Abstract

The effect of ruminal and duodenal infusion of maize starch and casein on plasma growth hormone (GH) concentrations was studied in sheep. Plasma GH concentrations were decreased after feeding. Maize starch and casein infusion into the rumen prolonged the decrease after feeding whereas duodenal infusion of maize starch did not affect the decrease. Duodenal infusion of casein inhibited the decrease in GH after feeding. These data suggest that maize starch and casein are degraded by microbial fermentation and increased VFA production in the rumen may be involved in the prolonged decrease in GH secretion after feeding.
