日粮中添加不同纤维分解菌对鹅生产性能的影响

Effect of Different Cellulolytic Bacteria in Daily Ration on the Production Performance of Geese

为研究日粮中添加不同纤维分解菌对鹅生产性能的影响,试验选用0日龄健康农安本地鹅64只,随机分成4组,每组16只。试验组从0日龄每3d饲喂一次纤维分解菌,喂菌量为109 CFU/mL,纤维分解菌分别为:从鹅肠道内分离扩增的芽孢纤维分解菌(A组);从白蚁肠道内分离扩增的芽孢纤维分解菌(B组);从牛粪中分离扩增的芽孢纤维分解菌(C组);对照组用等量的蒸馏水代替。测定鹅日增重、采食量、料重比。结果表明,A、B、C组提高了鹅的日增重、采食量,显著降低了料重比,B组作用效果较好、A组次之,C组较差。

To study effect of different Cellulolytic bacteria in daily ration on the production performance of geese,64 Nong＇an local geese with 0-day-old were selected.The experimental geese were divided into four groups,each group 16.From 0-day-old on the cellulose decomposing bacteria was fed to test group once every three days,feeding amount of 109 CFU/mL.Cellulolytic bacteria： isolated from goose tract Cellulolytic bacterium Bacillus amplification（A group）,isolated from termite gut Cellulolytic Bacterium Bacillus Amplification（B group）;isolated from cow dung fiber amplification of Bacillus Decomposing Bacteria（C group）.Control group was fed the same amount of distilled water instead.The results showed that A,B,C bacteria can increase goose daily gain,feed intake,feed conversion was significantly reduced.B bacteria was better,A bacteria followed,C bacteria was poor.
