不同纤维水平日粮对肉鹅生产性能的影响

Effects of Different Dietary Fiber Levels on Production Performance of Meat Geese

试验分为A、B、C、D4组,日粮中分别添加5.0%、12.6%、21.0%和28.0%的皇竹草草粉,各组饲料能量和蛋白质含量基本相同,纤维含量分别为5.03%、6.97%、8.98%、10.98%。试验结果表明:鹅日增重A、B组高于D组(P<0.05),与C组差异不显著;日采食量A、B组高于D组(P<0.01);料重比组间差异不显著;日粮不同纤维水平对屠宰性能的影响不大。综合分析得出,鹅日粮中添加12.6%的皇竹草草粉,纤维水平为6.97%的B组生产性能较好;皇竹草草粉的添加量达到28.0%,纤维水平为10.98%的D组较差。

The experiment was conducted to study the effects of dietary fiber levels on the production performance of meat goose. The trial was divided into A, B, C and D groups, which contain 5.0%, 12.6%, 21.0% and 28.0% pennisetum hydridum meals respectively, and the level of fiber of each group was 5.03%, 6.97%, 8.98% and 10.98% respectively. The levels of energy and protein of four groups were same. The experiment results showed that the average daily gain of groups A and B were higher than that of group D （P〈0.05）, the average daily feed intakes of groups A and B were significant higher than that of group D （P〈0.01）, the ratio of feed to gain and the slaughter performance of each group showed no obvious difference. In a word, the production performance of group B was the best, the group D was the worst among the four groups.
