普罗宝酶解蛋白粉替代部分豆粕对妊娠母猪生产性能的影响*

 于2009年10月8日至2010年1月20日，在云南邦格农业集团有限公司建水生猪养殖基地，选择48头初产长大二元杂种怀孕母猪，随机分为4组，第1组为对照组，2~4组为试验组，分别在日粮中添加0，3%，5%，10%的普罗宝酶解蛋白粉（EP - 45），研究EP - 45替代部分豆粕对妊娠母猪生产性能影响。结果表明：与对照组相比，5%与10%添加组的妊娠母猪背膘厚、产仔数和仔猪初生重均存在显著差异（P<0.05），且5%添加组的产活仔数也与对照组存在显著差异（P<0.05）。

The Effect of Adding EP-45 to Substitute Part of Soybean Meal in the Ration on the Reproductive Performance of Pregnant Sows
