摘 要：
通过在基础日粮中分别添加 2种不同寡聚糖和抗生素比较其对仔猪的生长性能、腹泻率及料重比的影响。选用 9窝 72头平均日龄为 41d的长白×皮特兰×枫泾三元杂交断奶仔猪进行试验。试验分 3组 ,每组 2个重复。对照组 (Ⅰ )为抗生素组 ,试验组Ⅱ为甘露寡糖组 ,试验组Ⅲ为低聚果糖组。 2 8d的饲养试验表明 :Ⅱ、Ⅲ组在试验 1～ 4周全程体增重分别为 (6 2 5± 1 81 )kg和 (6 0 3± 2 59)kg ,日增重分别为 (2 2 3 0 7±64 54)g和 (2 1 5 33± 1 0 0 91 )g,均显著高于Ⅰ组体增重 (5 36± 2 0 6)kg和日增重 (1 91 37± 73 55)g(P <0 0 5) ;Ⅰ组的腹泻率为 (4 90±4 48) % ,低于Ⅱ组 (5 64± 4 40 ) %和Ⅲ组 (6 37± 5 33) % ,Ⅲ组腹泻较严重 ,但各组间差异不显著 (P >0 0 5) ;1～ 4周试验全程Ⅱ组和Ⅲ组的料重比分别为 (2 0 0± 0 2 5)和 (2 0 9± 0 0 8) ,均显著低于Ⅰ组 (2 41± 0 1 3) (P <0 0 5)。结果表明 :Ⅱ、Ⅲ组低聚寡糖的使用效果明显优于Ⅰ组抗生素。寡聚糖在一定程度上可替代抗生素 ,且不同低聚寡糖的饲喂效果存在差异。

摘 要：
Two different kinds of oligosaccharides and antibiotic were supplemented respectively to the same basic dietary to investigate the effects on growth performance,diarrhea frequence and feed gain ratio in the piglet. A total of 72 L×P×F crossbred weaned piglets were assigned to three groups with two replicates in each group. Group Ⅰ (control) was added with antibiotic, group Ⅱ contained mannan-oligosaccharide and group Ⅲ fructooligosaccharide. The experiment lasted 28 days. The results showed that the average body weight gains (AWG) in group Ⅱ and Ⅲ were (6.25±1.81) kg and (6.03±2.59) kg, and the average daily weight gains (ADWG) in group Ⅱ and Ⅲ were (223.07±64.54) g and (215.33±100.91) g, respectively, both significantly higher than AWG (5.36±2.06) kg and ADWG (191.37±73.55) g in group Ⅰ(P<0.05). There were no significant difference in diarrhea frequency among group Ⅰ (4.90±4.48)%,Ⅱ(5.64±4.40)% and Ⅲ(6.37±5.33)%. The feed conversion ratios in group Ⅱ and Ⅲ were (2.00±0.25) and (2.09±0.08), higher than that (2.41±0.13) in group Ⅰ(P<0.05). Compared to the treatment groups, the control group showed poor performance. The results indicated that the oligosaccharides could replace the antibiotic in some degree, and there was some differences in the growth performance between different kinds of oligosaccharides.
