摘要 研究主要考察大米浓缩蛋白部分或全部替代鱼粉对断奶仔猪生长性能、养分消化率和肠道发育的影响。选择108头25日龄DLY断奶仔猪,按照单因素试验设计,分别饲喂对照日粮(含鱼粉5%),大米浓缩蛋白粉替代50%或100%鱼粉的日粮,试验期21 d。结果发现,大米浓缩蛋白替代50%鱼粉对断奶仔猪生长性能和养分表观消化率没有显著影响(P>0.05)。大米浓缩蛋白全部替代鱼粉显著降低日采食量和日增质量(P<0.05),显著提高料重比(P<0.05),同时显著降低能量、干物质和粗蛋白表观消化率(P<0.05)。各处理组对肠道绒毛高度、隐窝深度和绒毛高度/隐窝深度比值没有显著影响(P>0.05)。总结以上数据,大米浓缩蛋白可部分替代断奶仔猪日粮中鱼粉而不影响生长性能。
