摘要 文章旨在研究纳米硒和甘草提取物对初产母猪繁殖性能以及后代宫内发育迟缓(IUGR)哺乳仔猪生长性能的影响,选取妊娠90日龄二杂母猪(长×大,1胎)40头,按照体况一致原则随机分为两组,每组20个重复,每个重复1头母猪。对照组饲喂基础饲粮,试验组添加0.3 mg/kg纳米硒+500 mg/kg甘草提取物(以营养包方式添加)。每头母猪每天100 g,每日1次。试验期46 d(妊娠90日龄至哺乳期21 d)。结果显示,2个处理组母猪繁殖性能无显著差异(P>0.05);纳米硒+甘草提取物组仔猪哺乳期窝增重比对照组高5.49 kg(P<0.05);IUGR仔猪哺乳期增重比对照组高0.22 kg(P<0.05)。综合来看,妊娠后期母猪饲粮添加纳米硒和甘草提取物对母猪繁殖性能无影响,但能改善后代IUGR仔猪哺乳期长势。
