低温环境和维生素E对康贝尔蛋雏鸭生产性能的影响
|
摘要
研究在低温环境下饲养和日粮添加维生素E对康贝尔蛋雏鸭生产性能的影响。试验采用2×3交叉重复试验的方法,将1日龄的康贝尔蛋雏鸭180只随机分为6组,每组5个重复,每个重复6只,设计两个温度水平,低环境温和适宜温度,适宜温度为鸭舍正常培育雏鸭的环境温度,低温环境的温度开始试验时与适宜温度环境保持一致,分别在5、9、25日龄比适温组调低4℃~5℃。试验适温和低温饲养雏鸭的饲料中添加的VE分别为20 IU/kg、200 IU/kg、400 IU/kg,试验期32 d。试验结果表明,低温组康贝尔蛋雏鸭各阶段的日增重和成活率显著低于适温组(P<0.05),而低温组康贝尔蛋雏鸭的平均采食量和平均料肉比都明显要比适温组高(P<0.05);当维生素E添加剂量为200 IU/kg时,低温和适温饲养康贝尔蛋雏鸭日增重显著提高(P<0.05);蛋雏鸭日粮添加200 IU/kg维生素E的饲喂效果较为理想。
This experiment aims at researching the effects of low temperature and the effects of vitamin E on production performance of ducklings. 2×3 cross repetition test was used to divide 180 young duck egg ducks at 1 days old randomly into 6 groups. Each group had 5 repetitions, each repeated 6, designed two temperature levels, low temperature and suitable temperature. The suitable temperature was the ambient temperature of ducklings in ducks. The temperature of the low temperature environment began to be tested and appropriate. The temperature environment remained the same, which was lowered by 4~5 C at 5, 9 and 25 days of age respectively.The VE added to feed for low temperature rearing ducks was 20 IU/kg, 200 IU/kg and 400 IU/kg respectively, and the test period was32 D. The test results showed that the daily weight gain and survival rate of the ducks at all stages of the low temperature group were significantly lower than that of the suitable temperature group(P<0.05), while the average feed intake and the meat ratio of the ducks in the low temperature group were higher than those of the suitable temperature group(P<0.05). When the vitamin E additive amount was200 IU/kg, the low temperature and suitable temperature reared the duck egg ducklings. The daily weight gain was significantly improved(P<0.05); the addition of 200 IU/kg vitamin E to the egg duckling diet was more effective.
