益母草对绿壳蛋鸡血液生化指标及激素的影响

将280只50周龄健康、生产性能相近的黑羽绿壳蛋鸡随机均分为4组,每组设5个重复,每个重复14只。对照组饲喂基础日粮,试验组在基础日粮中分别添加0.5%、1.0%、1.5%益母草粉,观察其对黑羽绿壳蛋鸡血清生化指标、血液激素及卵巢的影响。结果表明,与对照组相比,在绿壳蛋鸡日粮中添加1.0%和1.5%益母草粉可显著降低血清中总胆固醇(TC)、甘油三酯(TG)和低密度脂蛋白(LDL)含量,提高高密度脂蛋白(HDL)、雌二醇(E₂)和促卵泡激素(FSH)含量,增加卵巢相对重量。益母草可以影响脂肪代谢,具有降低血脂的作用,考虑到生产成本问题,最适添加量为1.0%。

Effects of Leonurus heterophyllus Sweet on Biochemical Parameters and Hormone in Green-eggshell Chickens

Two hundred and eighty 50-weeks Green-eggshell chickens were randomly allotted to 4 treatments, each group was assigned 5 replications and 14 layers per replication. The control group was provided with corn-soybean meal basal diet, the trial groups were respectively fed the basal diet supplemented with 0.5%, 1.0% and 1.5% Leonurus heterophyllus Sweet, in order to observe the influence to biochemical parameters, hormone and ovary in Green-eggshell chickens. The results were showed as follows: compared with the control group, 1.0% and 1.5% Leonurus heterophyllus Sweet added to Green-eggshell chickens could significantly decrease TC,TG and LDL,apparently increase HDL,E₂,FSH and ovarian relative weight. Leonurus heterophyllus Sweet could affect fat metabolism, reduce the content of blood lipid. For saving cost,the most appropriate volume was 1.0%.
