Metabolic Effects of Growth Hormone and Diethylstilbestrol in Lambs. II. Effects of Daily Ovine Growth Hormone Injections on Plasma Metabolites and Nitrogen-Retention in Fed Lambs3

Abstract

Studies were conducted to evaluate the effects of daily injections of ovine GH in fed sheep on plasma levels of NEFA, glucose, insulin, PUN and FAA-N. The effects of treatment on nitrogen balance were also observed. It was noted that GH treatment resuited in increased levels of plasma NEFA, glucose and insulin and a decrease in PUN. No detectable effect was noted on plasma FAA-N. Nitrogen-retention was almost doubled during GH treatment. These effects of GH treatment are in agreement with results reported by others in both ruminant and nonruminant species.
