两种木聚糖酶对黄羽肉鸡生长性能和养分代谢率的影响
Effects of Two Xylanases on Growth Performance and Nutrient Metabolizability of Yellow-feather Broilers
摘要
Abstract
The experiment was aimed to investigate the effects of xylanases from different sources on growth performance and nutrition metabolizability of Yellow-feather broilers.540 of healthy 1-day-old Yellow-feather broilers were randomly divided into three groups with 6 replicates per group and 30 broilers per replicate,and the trial period was 42 d.The control group was fed a wheat-corn-soybean meal diet,and groups A and B fed the basal diet supplemented with 200 g/t Trichoderma xylanase (30 000 IU/g)and bacterial xylanase (30 000 IU/g),respectively.The re-sults showed that,compared with the control group,the average daily gain,apparent metaboliz-ability of crude fat,crude fiber,calcium and phosphorus,and apparent metabolizable energy were significantly higher (P<0.05),the F/G were significantly decreased (P<0.05)in both groups A and B,their apparent metabolizabilities of crude protein increased by 5.90% (P<0.05)and 3.54%(P>0.05),respectively.There were no significant differences for all the determined indexes between groups A and B (P>0.05).The supplementation of Trichoderma xylanase or bacterial xylanase at 200 g/t could improve nutrient metabolizability,thus improve growth performance of broilers,while the effects of Trichoderma xylanase were better than that of bacterial xylanase.关键词
