摘　　要：为研究酵母水解物(AY)对母猪泌乳性能及仔猪生长发育的影响,本试验选取膘情、体重、胎次相近,妊娠108 d左右的健康PIC经产母猪20头,随机分成2组,每组10个重复,每个重复1头。对照组饲喂基础日粮,试验组在基础日粮中添加0.3%的酵母水解物,试验至仔猪21日龄断奶结束。结果表明,与对照组相比,试验组仔猪断奶时存活率、母猪日采食量和泌乳量分别提高7.49%(P<0.05)、3.8%(P<0.05)和14.9%(P<0.01);试验组母猪血清中尿氮含量增加61.6%(P<0.05),总蛋白、白蛋白的含量变化不显著(P>0.05);必需氨基酸中,蛋氨酸水平有增加的趋势(0.05<P<0.1),其他必需氨基酸水平变化不显著(P>0.05);非必需氨基酸中,试验组母猪血浆中谷氨酰胺比对照组显著提高50.75%(P<0.05),此外,血浆中脯氨酸、甘氨酸、天冬氨酸、羟脯氨酸、组氨酸和丙氨酸含量均有上升趋势(0.05<P<0.1)。由此可见,酵母水解物能够提高哺乳母猪泌乳性能,并能改善仔猪的生长状况。This experiment was conducted to study the effect of autolyzed yeast （AY）on lactation performance of sow and the growth of piglets.A total of 20 PIC sows were assigned into the two dietary treatments on weight and parity,includ- ing control diet （control group）and the control diet supplementation with autolyzed yeast （AY）3 g/kg （AY group）.The re- suits showed that.The supplementation of AY significantly increased lactation yield （P 〈 0.01 ）and ADFI （P 〈 0.05） of sows,and the survival rate of piglets also increase in AY group（P 〈 0.05 ）.Supplement of AY significantly increased blood urinary nitrogen content（P 〈 0.05）,but there was no difference in TP and ALB between groups（P 〉 0.05）.In EAA,sup- plement of AY had a tendency to increase plasma Met （0.05 〈 P 〈 0.1）in sows,while,other EAA such as Lys,Leu and Val had no difference from control group.In NEAA,Gln （P 〈 0.05）showed a significantly increase in AY group.Mean- while,plasma Pro, Gly,Asp,His and Ala（0.05 〈 P 〈 0.1 ）bad an increased tendency compared with control group.In con- clusion,supplementation of AY （3 g/kg）not only can improve lactation performance of sows and the growth of piglets but also can adjust the metabolism of amino acid.
