摘要

本试验旨在研究小麦替代玉米饲粮添加木聚糖酶对生长猪生长性能、结肠菌群和氮排放的影响。试验选用126头体重约为45 kg的“杜×长×大”三元杂交生长猪，分为7组，每组3个重复，每个重复6头猪。具体分组是：对照组（CON组）饲喂玉米-豆粕型基础饲粮，W20组饲喂20%小麦基础饲粮，W20X组饲喂20%小麦基础饲粮+200 U/kg木聚糖酶，W40组饲喂40%小麦基础饲粮，W40X组饲喂40%小麦基础饲粮+200 U/kg木聚糖酶，W60组饲喂60%小麦基础饲粮，W60X组饲喂60%小麦基础饲粮+200 U/kg木聚糖酶。试验期50 d。结果表明：与对照组相比，W60组平均日增重显著降低（P<0.05），料重比显著提高（P<0.05），结肠梭菌、大肠杆菌数量显著增加（P<0.05），粪氮排放量显著增加（P<0.05）；W20X和W40X组间平均日增重、料重比差异不显著（P>0.05）；W40X组结肠乳酸杆菌数量显著增加（P<0.05），大肠杆菌、梭菌数量显著降低（P<0.05），粪样pH、脲酶活性显著降低（P<0.05）。综上所述，木聚糖酶有明显的益生作用，能刺激肠道有益菌增殖并抑制有害菌增殖，减少氮排放。本试验条件下，添加200 U/kg木聚糖酶的小麦饲粮中，小麦最适替代量为40%。

Abstract

This experiment was conducted to investigate the effects of xylanase supplementation in diets with corn replaced by wheat on growth performance, intestinal microbiota and nitrogen emissions of growing pigs. A total of 126 growing pigs (Duroc×Landrace×Yorkshire) with an average body weight of 45 kg were allotted to 7 groups with 3 replicates in each group and 6 pigs in each replicate. The groups were control group (CON group, corn-soybean meal-based diet), W20 group (20% wheat-based diet), W20X group (20% wheat-based diet+200 U/kg xylanase), W40 group (40% wheat-based diet), W40X group (40% wheat-based diet+200 U/kg xylanase), W60 group (60% wheat-based diet), and W60X group (60% wheat-based diet+200 U/kg xylanase), respectively. The experiment lasted for 50 d. The results showed as follows: compared with the control group, the average daily gain was significantly reduced (P<0.05), and feed to gain ratio was significantly increased (P<0.05), and the number of Clostridium and Escherichia coli in colonic and fecal nitrogen emission were significantly increased in W60 group (P<0.05); the average daily gain and feed to gain ratio were not significantly different between W20X group and W40X group (P>0.05); the number of Lactobacillus was significantly increased (P<0.05), the number of Clostridium and Escherichia coli was significantly decreased (P<0.05), and fecal pH and urease activity were significantly decreased in W40X group (P<0.05). In conclusion, the supplementation of xylanase in wheat-based diet can stimulate the proliferation of intestinal beneficial bacterium, and decrease nitrogen excretion. Results also indicate that the optimal replacement level of wheat is 40% in 200 U/kg xylanase diets for growing pigs.
