Effect of Restricted Feed Intake on LH Levels in Female Rats

Abstract

Adult female rats were maintained for 20 days on 100% or 50% of ad libitum feed intake or 50% ad libitum feed intake plus powdered glucose ad libitum. Body, pituitary and ovarian weights were reduced in animals on restricted feed intake while the same treatment plus glucose supplementation resulted in body and organ weights similar to full-fed animals (feed treatment, P<.01). The mean plasma LH concentration in rats on restricted feed intake was lower (P<.01) than that of full-fed rats or rats on restricted feed plus supplemental glucose. Restricted feeding with glucose supplementation resulted in a mean plasma LH concentration similar to that of full-fed controls. Anterior pituitary LH concentration was not significantly affected by feed level. Copyright © 1972. American Society of Animal Science . Copyright 1972 by American Society of Animal Science.
