紫花苕草粉替代部分精料对织金白鹅生长性能的影响

Effect of Vetch Meal Replace Part Concentrated Feed on Growth Performance of Zhijin Geese

试验选用5周龄织金白鹅100只，随机分成5组（Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ组），每组20只。Ⅰ组饲喂对照日粮，对照日粮精料不添加紫花苕草粉，Ⅱ、Ⅲ、Ⅳ、Ⅴ组分别饲喂用紫花苕草粉替代10％、20％、30％、40％原精料的试验日粮，进行为期28d饲养对比试验。结果表明，饲喂不同日粮对Ⅰ、Ⅱ、Ⅲ、Ⅳ、Ⅴ组各组之间织金白鹅平均日增重、白鹅的死淘率均差异不显著（P〉0．05）。平均日采食量及料重比Ⅳ和Ⅴ组显著高于Ⅰ组（P〈0．05），Ⅲ组与Ⅰ组差异不显著（P〉0．05）。第Ⅲ组的经济效益最高，利润为10．32元／只，比第1组高8．63％。综上所述，在生长期（5～9周龄）织金白鹅饲粮精料中紫花苕草粉替代量为20％的试验组效果最好，因此，建议在（5～9周龄）织金白鹅饲粮精料中紫花苕草粉替代量为20％比较适宜。

One hundred 5-week-age Zhijin geese were randomly divided into five groups with 20 geese in each group. Group I was fed the control diet and without adding vetch meal. Group Ⅱ, Ⅲ, Ⅳ, Ⅴ fed the concentrated feed was replaced by vetch meal for 10%,20%, 30% and 40% diet respectively. The experiment lasted 28 days. The results showed that different diet had no significant impact on the average daily gain, death rate of eliminate among five group （P〉0.05）. Average daily feed intake and feed/gain of group Ⅳ and Ⅴ were significantly higher than group Ⅰ （P〈0.05）,and group Ⅲ and i had no significant difference （P〉0.05）. Group Ⅲ obtained the highest economic benefit of all groups. In this group one goose profited average 10.32 yuan and 8.63 percent higher than group Ⅰ. In total,when the vetch meal replaced 20% concentrated feed in the growing Zhijin geese diet, the best effect could be obtained. Therefore, it is recommended that 20% concentrated feed was replaced by vetch meal in the growing Zhijin geese diet.
