棉籽粕、菜籽粕和葵花粕对1 ～2月龄肉仔鸡生长性能的影响

选择１ 月龄的艾维茵肉仔鸡２４７ 只， 随机分为１３ 组， 每组１９ 只， 进行３０ ｄ 的饲养试验。在不同处理组的日粮中分别添加不同剂量的棉籽粕、菜籽粕和葵花粕以替代部分豆粕。结果： 在１ ～２ 月龄肉仔鸡的日粮中， 葵花粕的添加量以４ ％ 为最佳， 其日增重比对照组提高１１ ％ （ Ｐ ＞００５） 。棉籽粕和菜籽粕添加量分别为１０ ％ ～１５ ％ 时， 肉鸡日增重和对照组无明显差异 （ Ｐ ＞ ００５） 。棉籽粕和菜籽粕同时添加时要优于单一添加，其日增重比对照组提高５ ％ （ Ｐ ＞ ００５） 。在开发和利用棉籽粕和菜籽粕时， 要注意日粮中赖氨酸、蛋氨酸和动植物油的添加， 其日粮中赖氨酸含量要比推荐量提高８ ％ 左右为宜。

The Effect of Cottonseed,Rapeseed and Sunflower Meals on Daily Gain of Broilers

Two hundred and forty seven one month old broilers were divided into 13 groups(19 broilers for each group).The period of experiment was 30 days.The results showed that the optimum contents of cottonseed,rapeseed,and sunflower meals in diets were 10%～15%,10%～15% and 4%,respectively,which could partially replace soybean meal when both cottonseed meal and rapeseed meal were added into one diet.Daily gain was not differen between the groups in the trials.(P>0 05).The study suggested that the content of digestible lysine be 8% above the recommended level when cottonseed,rapeseed or sunflower meals was added to the diet and the levels of methionine and soybean oil be also taken into account.
