| 摘 要： | 选取192头体重相近(平均体重为5.27kg)的(21±2)日龄PIC断奶仔猪,按胎次、公母分4个处理组,每组3个重复,每个重复16头。试验分两个阶段:21～35日龄、35～49日龄,研究谷氨酰胺、壳聚糖单独和复合添加对断奶仔猪生产性能和血液生化指标的影响。结果表明:①日粮中单独添加1%谷氨酰胺或0.04%壳聚糖有提高断奶仔猪日增重、降低料重比的趋势。②谷氨酰胺与壳聚糖复合添加使用在一些指标上优于单独添加,体现出一定的协同作用。

| Abstract: | 192 weanling pigs(5.27 kg;21±2 d;PIC) were blocked by initial weight and alloted to 4 treatments,each group included three replicates of 16 weanling pigs.The study was divited into two phases(21～35 d and 35～49 d) and was conducted to determine the effects of GLN,and CS,separately or in combination,on the growth and blood biochemical indexes.The results showed:①The adding(1%) GLN or(0.4%) CS in ratin can improve ADG,GLN reduced G/F significantly in each trail period.②The GLN combined with CS adding in ration is better than separately adding on some index. |
