Influence of Nutrition on Ovulation Rate in the Ewe

Abstract

The effect of nutrition on ovulation rate in the ewe is reviewed with particular reference to the role of protein and energy and the time of effect during the cycle.Ovulation rate is increased by both protein and energy. In the case of protein this wasshown to be accompanied by increased plasma levels of FSH and androstenedione at about the time of luteolysis, while levels of LH were unaffected. Increased hepatic oxidativeenzyme activity is proposed as a mechanism by which nutrient intake may influence ovulation rate. © 1988 ASEG.
