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

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

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)。

Forty-eight pregnant gilts of the two way crossbreds were selected and randomized into four groups with one controlled group and three tested ones from October 10th 2009 to January 20th 2010 at Bangge Agricultural Group Co.Ltd.in Jianshui.Different ratios of EP-45 were added in the daily ration of the groups as 0,3%,5%,10% to investigate the effect of adding EP-45 to substitute part of soybean meal in the ration on the reproductive performance of sow.The result showed that there were significant difference of the back fat thickness of pregnant sows,the litter size and piglet birth weight among the control group,the 5% and 10% observed groups（P0.05）,there was significant difference of number born alive between the control group and 5% observed group（P0.05）.
