The Importance of L-Arginine on Gestating Sows

Main Article Content

Wariya Kosoom


L-Arginine is an essential amino acid or some textbooks are classified as semi-essential amino acid in swine. This article, research compiled “The importance of L-Arginine on gestating sows”. The data showed that L-Arginine supplementation is an important part in protein production and helps in the synthesis of hormones involved in vascular formation and growth of the placenta and embryo. L-arginine supplementation can be supplemented at the lowest level of 0.25% to the maximum level of 1% to increase sow production performance in terms of numbers and weight of piglets at birth and at weaning, reduce dead piglets and also IUGR%. However, the amount of L-arginine supplementation in swine feed have to consider the value and appropriateness of the price on feed formulation. Meanwhile, L-Arginine plays a significant role in the nutrition of gestating sows.
