【摘要】 本试验选用 1日龄樱桃谷肉鸭 60 0只 ,随机分为 10个组 ( 9个试验组和 1个对照组 ) ,每组 2个重复 ,每个重复 30只肉仔鸭。试验组采用二因素、三个水平的完全随机设计 ,即在饲粮中添加 3%、6%和 9%的大豆油 ,每个比例分别添饲 1周、2周、3周 ,旨在研究日粮中添加大豆油的用量和时间对肉鸭生产性能的影响。结果表明 :各试验组之间以及各试验组与对照组之间肉鸭的死亡率无显著差异 (P >0 .0 5) ;各试验组与对照组之间肉鸭的饲料转化率有显著差异 (P <0 .0 5) ,各试验组之间肉鸭的饲料转化率无显著差异 (P >0 .0 5) ;添加大豆油的比例、时期及比例与添饲时期的互作对肉鸭的日增重均有极显著的影响 (P <0 .0 1) ,而以添加 6%的比例添饲两周的效果最好更多还原

【Abstract】 The trial was made to study on the effects of soybean oil on the performance of meat ducks. 600 cherry-vally meat ducks(0-day-old) were divided into 10 groups (9 experiment groups and 1 control group) with 2 subgroups in each. There were 30 meat ducks in each subgroup. The experiment was designed on two factors,three levels in each factor. Basal diet was added with 3%,6% and 9% soybean oil. Each ratio was fed for 1 week, 2 weeks and 3 weeks respectively. The results showed that the best effect was adding 6% soybean oil and feeding for 2 weeks.更多还原
