发酵香椿叶对蛋鸡生产性能、蛋品质和血浆生化参数的影响

Effects of fermentted toona sinensis leaf on laying performance,egg quality and serum biochemical index of laying hens

为探讨发酵香椿叶对蛋鸡产蛋性能、蛋品质和血浆生化指标的影响,本研究选取300日龄京粉8号蛋鸡共320只,随机分成4组,每组设定8个重复,每个重复10只鸡。在试验期间,对照组饲喂基础饲粮,试验组在基础饲粮中分别添加1%、2%、3%三个不同梯度的发酵香椿叶。经过7天预试期和60天试验期,得出以下结论:在蛋鸡生产性能方面,饲粮添加发酵香椿叶可以提高产蛋率,显著增加平均蛋重(P<0.05);在蛋品质方面,添加发酵香椿叶可以增加蛋白高度,试验第60天,蛋黄色泽显著增加(P<0.05);在血浆生化指标方面,添加发酵香椿叶试验第60天,血浆中GLU含量显著降低(P<0.05),ALB和HDL含量显著提高(P<0.05),加入发酵香椿叶3%试验组的血浆中BUN含量显著下降(P<0.05),表明发酵香椿叶可以促进对蛋白质的消化和吸收,改善脂代谢水平。

This study aimed to study the effects of fermentted toona sinensis leaf on laying performance,egg quality and serum biochemical index of laying hens.A total of 320 No.8 Jingfen laying hens(300-day-old)were selected and randomly divid-ed into four groups with eight replicates in each group and ten hens in each replicate.The control group was fed the basal diet,and the experimental groups were supplemented respectively with 1%fermentted toona sinensis leaf,2%fermentted toona sinen-sis leaf,and 3%fermentted toona sinensis leaf.The pre-trial period was seven days,and the formal trial period was 60 days.The results showed that:in terms of the production performance,compared with that of the control group,the egg production rate of the trial group was increased,and the average egg weight was significantly increased(P<0.05);In terms of the egg quality,al-bumen height was increased,and on day 60 of experiment,the egg yolk color was significantly increased(P<0.05);On the se-rum biochemical indicators,on day 60 of experiment,the plasma contents of glucose(GLU)was significantly decreased(P<0.05),and the contents of plasma of albumin(ALB),high density lipoprotein(HDL)were significantly increased(P<0.05),the addition of 3%fermentted toona sinensis leaf could significantly reduce the blood urea nitrogen(BUN)(P<0.05).The fermentted toona sinensis leaf could improve the digestion and absorption of protein,and improve the level of lipid metabolism.
