摘要
Abstract
This experiment was conducted to investigate the effects of glucose oxidase (GOD) on digestibility of main nutrients and cecum microorganism in laying hens. One hundred and eighty 26-week-old Hyline layers were randomly divided into 5 groups. Laying hens in group Ⅰ,Ⅱ,Ⅲ,Ⅳ and Ⅴ were fed basal diets with addition of 0, 0.1%, 0.2%, 0.3% and 0.4% GOD. The results showed that the apparent digestibility of nutrients in laying hens fed with GOD increased. Compared with those of the control group, the apparent digestibility of crude protein (CP) in experimental groups increased by 15.25% (P<0.05), 28.40% (P<0.01), 23.32% (P<0.01) and 26.10% (P<0.01) respectively; the apparent digestibility of cal-cium increased by 3.37% (P>0.05), 4.71% (P>0.05), 8.01% (P<0.01) and 7.30% (P<0.05) respectively; the ap-parent digestibility of total phosphorus increased by 17.74% (P>0.05), 16.30% (P>0.05), 24.58% (P<0.01) and 27.32% (P<0.01) respectively. The number of the Lactobacillus increased significantly and that of E.coli decreased in cecal of laying hens fed diets with addition of 0.2%～0.4% GOD. In conclusion, GOD could regulate the balance of cecum microorganism and improve the digestibility of nutrients.关键词
