摘要
选用 1日龄樱桃谷肉鸭 900只，随机分为 9个组，每组 2个重复，每个重复 50只。试验组采用二因素、每个因素三个水平的完全随机设计，以研究光照制度对肉鸭生产性能和脂肪沉积的影响。结果表明：光照制度和公母分群方式分别对肉鸭日增重有显著影响和极显著影响；对肉鸭死亡率和饲料转化率均无显著影响；对肉鸭腹脂率和皮脂率均有极显著的影响。以间歇光照制结合公母分群饲养的效果最好。
The trial was conducted to analysed effects of lighting productivity and fat deposition in meat ducks.900 1－ day－ old cherryvally meat ducks were randomly divided into 9 groups(2 repeat each group,50 each repeat). Twofactors and three levels per factor were considered.The result indicated lighting system and sex had no remarkable effect on ducks'death rate and feed efficiency. but a significent influence on increase of bodyweight per day,the subcutaneous fat rate and abdominal fat rate.Lighting at intervals and the rearing way of sex seperation had the best effect.
