摘要
研究采用单因子试验,选取日龄相同、体重无差异的350 d产蛋鸭625只,随机分为5个处理组,每个处理5个重复,每个重复25只。处理1组为对照组,2组添加膨化油菜籽1.5%、3组添加膨化油菜籽3.5%、4组添加膨化油菜籽5.5%、5组添加膨化油菜籽7.5%,以蛋鸭的产蛋性能和鸭蛋蛋黄品质为参考,探讨膨化油菜籽在蛋鸭日粮中的适宜添加水平。结果表明,蛋鸭日粮中添加3.5%~5.5%的膨化油菜籽能有较好的产蛋性能,添加5.5%的膨化油菜籽能极显著增加蛋黄色泽。
The 625 laying ducks of 350 d with the same age and no difference in weight were used to be selected and randomly divided into 5 treatment groups with 5 repeats and 25 each repeat. The 1 group was treated as control group, and the 2 group was added expanded rapeseed in 1.5%, and the 3 group was added compound rapeseed 3.5%, and the 4 group was added expanded rapeseed 5.5%, and the 5 groups was added expanded rapeseed 7.5%. Refering to the laying performance and egg yolk quality, the suitable addition level of expanded rapeseed in egg duck diet was discussed. The results showed that the diet of laying ducks with 3.5%-5.5% expanded rapeseed could produce better egg lay- ing performanee, and the 5.5% of expanded rapeseed could significantly increase yolk color.
