摘要
为了探讨啤酒酵母葡聚糖在断奶仔猪日粮中的适宜添加剂量及其对断奶仔猪细胞免疫功能的影响,本研究进行了2个试验。试验1选用100头(28±2)d断奶的二元杂交断奶仔猪,按单因子试验设计随机分为5个处理,分别饲喂含葡聚糖0、25、50、100mg/kg和200mg/kg的日粮。结果表明:随葡聚糖添加剂量的增加,平均日增重在14 ̄28 d及0 ̄28 d呈二次曲线变化(P<0.05)。试验2选用80头(28±2)d断奶的二元杂交断奶仔猪,随机分为2个处理,分别饲喂含葡聚糖0mg/kg和50mg/kg的日粮。在试验的第14天和第28天,每重复取1头仔猪前腔静脉采血,测定外周血淋巴细胞转化率。结果显示,在断奶仔猪日粮中添加50mg/kg葡聚糖提高了仔猪在14 ̄28d及0 ̄28d的日增重(P<0.05)。而且,也提高了仔猪在0 ̄14 d、0 ̄28 d及28 ̄35 d的平均日采食量(P<0.05)。但是对淋巴细胞转化率没有影响。结果表明:在断奶仔猪日粮中添加50mg/kg啤酒酵母葡聚糖,可以提高断奶仔猪的生产性能,而且没有性别差异。
