蟛蜞菊组成日粮对合浦鹅养分利用和生产性能的影响

【目的】探讨蟛蜞菊作为日粮主要成分对鹅生长性能和养分利用率的影响。【方法】将96羽21日龄体重相近的合浦鹅随机分为4组,每组3个重复,每个重复8羽（4公4母）;分别喂4种不同日粮：日粮1为基础精料＋鲜象草;日粮2为基础精料＋蟛蜞菊鲜草;日粮3为基础精料＋10%蟛蜞菊干草粉＋蟛蜞菊鲜草;日粮4为基础精料＋22%蟛蜞菊干草粉＋蟛蜞菊鲜草。试鹅全舍饲,预饲7d后开始进行42d的饲养,期间进行消化代谢跟踪,测定日粮养分的消化代谢率。试验结束后测定试鹅血液生化指标和屠宰性能。【结果】日粮组4的试鹅干物质和能量表观消化率明显低于日粮组1、2和3（P〈0.05）;但日粮组2、3和4的纤维物质（酸性洗涤纤维、中性洗涤纤维和半纤维素）消化率明显高于日粮组1（P〈0.05）;4组日粮间的养分消化率无显著差异（P〉0.05）;日粮组2试鹅的日均增重明显高于日粮组1和3（P〈0.05）以及日粮组4（P〈0.01）;但日粮组1和3之间没有显著差异（P〉0.05）。4组试鹅之间的血液生化指标和主要屠宰性能也没有显著差异（P〉0.05）。【结论】只要利用的形式和比例恰当,蟛蜞菊可作为饲养鹅的良好饲料。

Effect of diets supplemented with Wedelia Chinensis plants on nutrient digestibility and growth performance of Hepu geese

Objective]The studies were conducted to evaluate the effect of diets supplemented with Wedelia chinensis on nutrients digestion and growth performance of goose.Method]Ninety-six 21 d Hepu geese with similar body weight were randomly selected in 4 groups and given 4 treatments of diets:concentrate + fresh elephant grass(diet 1);concentrate + fresh W.chinensis(diet 2);concentrate +10% W.chinensis powder + fresh W.chinensis(diet 3);concentrate + 22% W.chinensis powder + fresh W.chinensis(diet 4) .Each group ...
