1饲料中添加蛋白酶对肉鸡性能、养分利用率、肠道形态和胴体品质的影响显示文摘试验在饲喂玉米、高粱为主的肉鸡日粮中补充大豆,并添加蛋白酶,研究蛋白酶对肉鸡性能、养分消化率、肠道形态和胴体品质的影响。试验选取1日龄AA肉仔鸡(43.8±1.31 g)256只,均为公鸡,随机分配到2×2试验设计方阵中,方阵包括正常组(玉米组和高粱组)和蛋白酶组(空白组和添加蛋白酶150 mg·kg^(-1)的试验组)。试验1~21 d为第一阶段,22~42 d为第二阶段。试验结果表明,第二阶段中,日粮中添加蛋白酶极显著提高肉鸡的平均日增重(ADG,P<0.01),在整个试验过程中显著提高(P<0.05)。在各个时期,正常组对肉鸡生产性能均无显著影响(P>0.05)。19~21 d时,添加蛋白酶可显著提高肉鸡的表观代谢能(AME),干物质(DM)、总能量(GE)和养分消化率(P<0.05)。此外,日粮以高粱为主时,AME、GE消化率有降低趋势(P=0.05),氮沉积率也有降低趋势(P=0.08)。40~42 d时,日粮中添加蛋白酶可显著提高AME,DM、GE和氮沉积率(P<0.05)。21 d时,日粮中添加蛋白酶极显著增加肠绒毛高度、肠绒毛与隐窝深度比值,极显著降低十二指肠、空肠、回肠的隐窝深度(P<0.01)。42 d时,日粮中添加蛋白酶显著增加空肠肠绒毛高度、绒毛高度与隐窝深度比值,显著降低隐窝深度(P<0.05)。日粮中添加蛋白酶显著增加胸肌重、24 h p H,显著降低胸肌的滴水损失(P<0.05)。试验结果表明,饲养阶段日粮中添加复合蛋白酶可提高肉鸡ADG;在第一阶段可改善AME、DM、GE和氮沉积率和肠道形态。补充蛋白酶可提高出栏重、胸肌重和24 h pH,降低胸肌的滴水损失。低单宁高粱日粮与玉米日粮相比,对肉鸡性能的影响相近。Xu X Wang H L Pan L Ma X K Tian Q Y Xu Y T Long S F Zhang Z H Piao X S 2017饲料博览2017,0,1:2
