摘　　要：国内外研究表明,妊娠母猪饲粮中添加L-精氨酸可提高其产仔数和出生窝重。调查我国养猪业使用精氨酸的情况表明,1/3的规模化猪场和饲料厂的妊娠母猪饲料中添加了精氨酸产品,精氨酸的价格较高是限制其在母猪饲料中使用的主要因素。推广饲料级精氨酸,可降低精氨酸价格,促进其普及应用,从而提高养猪利润。Dietary supplementation with L-arginine can improve reproductive performance in gestating gilts and sows.The Chinese swine industry is beset with a relatively small number of piglets weaned annually per sow. To ameliorate this problem, one third of large pig farms in China are using L-arginine and the feed-grade arginine product to enhance the litter size of sows. Currently, the high cost of L-arginine added to feed for pregnant sows is the major factor limiting the full adoption of the new arginine technology by the swine industry. When feed-grade L-arginine is available on a large scale to reduce its costs, L-arginine will be used widely in the world to improve profits of pig farms.
