摘要 选择配种后25 d的4~6胎的杜洛克母猪32头,按胎次基本相近的原则分成4个组,每组8头,研究含0%、20%、40%和60%的苜蓿草粉饲粮对母猪繁殖性能、血清生化指标的影响。结果表明:20%、40%苜蓿草粉组与对照组相比,产仔数和产活仔数均显著提高(P<0.05);初生个体重随苜蓿草粉添加水平的提高而降低,40%、60%苜蓿草粉组显著高于对照组(P<0.05)。但初生窝重以20%的苜蓿草粉组最高(P>0.05);断奶仔猪的成活率和断奶窝重以20%苜蓿草粉最高;20%和40%的苜蓿草粉并未降低母猪在妊娠期的增重,但60%的苜蓿草粉使妊娠期增重降低(P<0.05);随苜蓿草粉水平的提高,妊娠期背膘的增厚减少;20%和40%的苜蓿草粉显著提高了血清中T3和IGF-I量(P<0.05)。
