| Abstract: | N-carbamylglutamate(NCG) is a new feed additive, which had been used to improve reproductive performance in sow. Recent researches have revealed that NCG also has positive effect on the regulation of birth weight in piglet. This paper reviewed the advance of several nutrients and their effects on birth weight and its variation regulation, mainly focused on the effect of NCG on the regulation of birth weight in piglet and its potential molecular mechanism. This review will supply a theoretical and practical basis to control birth weight of piglet. |
