Relation between nutrition and fertility in pigs.

Abstract

A review of experiments on the effect of energy and protein intake on fertility in gilts suggested that a high energy intake shortly before oestrus (flushing) increased ovulation rate. Although high energy intake gave more ovulations than low energy intake, embryonic mortality was greater. The most suitable sequence during rearing, flushing and early pregnancy seemed to be low, high and low energy, respectively. (Abstract retrieved from CAB Abstracts by CABI’s permission)
