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。
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.
