摘要
研究了淀粉酶、木聚糖酶和益生素的不同组合对朗德鹅产肝性能、免疫性能、血清生化指标的影响.结果表明,与基础日粮相比,在日粮中同时添加200 g.t-1淀粉酶和100 g.t-1木聚糖酶可使朗德鹅的肥肝重提高18.6%、料肝比降低7.8%(P>0.05);而同时添加100 g.t-1木聚糖酶和4 000 g.t-1益生素可使肥肝重提高15.5%、料肝比下降9.7%(P>0.05),肝体比极显著提高(P<0.01),机体免疫能力也显著提高(P<0.05).
This paper aims to study the effects of different combinations of amylase,xylanase and probiotics on fatty liver performance,immune performance and serum biochemical indices of landes geese.The results showed as follows： compared with the basal diet,the fatty liver weight of landes geese fed diet supplemented with 200 g·t-1 amylase＋100 g·t-1 xylanase increased by 18.6%（P0.05）,and the ratio of feed to liver weight decreased by 7.8%（P0.05）.However,the fatty liver weight of landes geese fed diet supplemented with 100 g·t-1 xylanase＋4 000 g·t-1 probiotics increased by 15.5%（P0.05）,the ratio of feed to liver weight decreased by 9.7%（P0.05）,the ratio of liver weight to body weight improved extremely significant（P0.01）,and their immune performance also increased significantly（P0.05）.
