摘　　要：试验探讨非淀粉多糖酶对饲喂小麦-棕榈粕型日粮的广西三黄鸡生长性能、养分表观消化率及肠道健康的影响。选取360羽(公、母各半)9周龄广西三黄鸡随机分3组,每组3个重复,每个重复40羽鸡。对照组三黄鸡饲喂基础日粮,试验Ⅰ组、Ⅱ组分别在基础日粮中添加0.01%木聚糖酶、0.01%木聚糖酶+0.01%β-甘露聚糖酶。结果显示:与对照组相比,小麦-棕榈粕型日粮中添加木聚糖酶、β-甘露聚糖酶均可显著提高广西三黄鸡的平均日增重、平均日采食量(P<0.05),显著降低料重比(P<0.05);能够显著提高日粮能量、粗蛋白、无氮浸出物、干物质、粗脂肪的表观消化率(P<0.05);显著降低全肠食糜黏度以及盲肠中大肠杆菌含量(P<0.05),显著提高乳酸杆菌含量(P<0.05)。研究表明,小麦-棕榈粕型日粮中添加0.01%木聚糖酶或0.01%木聚糖酶+0.01%β-甘露聚糖酶,可提高三黄鸡日粮养分表观消化率,改善三黄鸡的生长性能,保障肠道健康。The experiment was conducted to investigate the effect of non-starch polysaccharide enzymes on growth performance, apparent nutrient digestibility and intestinal health of Guangxi Sanhuang chickens that fed a wheat-palm meal diet. A total of 360 nine-week-old Guangxi Sanhuang chickens(half in male and famale) were selected and randomly divided into three groups, with three replicates in each group and 40 chickens in each replicate. Chickens in control group were fed with a basal diet, and chickens in experimental group Ⅰ and group Ⅱ were fed with basal diet supplemented with 0.01% xylanase, 0.01% xylanase + 0.01% β-mannanase, respectively. The results showed that compare with control group, adding xylanase and β-mannanase in wheat-palm meal type diet significantly increased daily gain and daily feed intake(P<0.05), significantly decreased feed to gain ratio(P<0.05), significantly increased the apparent digestibility of dietary energy, crude protein, nitrogen free extract, dry matter and ether extract(P<0.05), significantly decreased the viscosity of chyme in the whole intestine and the content of Escherichia coli in cecum(P<0.05), and significantly increased the content of Lactobacillus(P<0.05). The study indicates that adding 0.01% xylanase or 0.01%xylanase + 0.01% β-mannanase in wheat-palm meal diet of Guangxi Sanhuang chickens can improve nutrient apparent digestibility, growth performance and intestinal health.
