【摘要】：本试验旨在探讨日粮中添加紫苏籽提取物对罗曼粉蛋种鸡产蛋高峰后期生产性能、激素水平、繁殖性能的影响。试验选用1 080只49周龄健康罗曼粉父母代蛋种鸡随机分为4个处理,每个处理分5个重复,每个重复54只。对照组饲喂基础日粮,试验组分别在基础日粮中添加紫苏籽提取物100、200、300 mg/kg,试验期为40 d。结果表明:与对照组相比,在日粮中添加300 mg/kg紫苏籽提取物能极显著提高蛋种鸡产蛋率和日均产蛋量(P0.01);与对照组相比,添加100、200、300 mg/kg紫苏籽提取物均能极显著提高蛋种鸡血清中孕酮(第20天)和雌二醇(第20、40天)的含量(P0.01),添加300 mg/kg紫苏籽提取物能极显著降低蛋鸡血清中睾酮含量(P0.01);与对照组相比,添加300 mg/kg紫苏籽提取物能显著提高蛋种鸡种蛋合格率、种蛋受精率和孵化率,降低死淘率(P0.05)。由此可知,在蛋种鸡产蛋高峰后期日粮中添加300 mg/kg紫苏籽提取物效果较好,能够提高蛋种鸡生产性能和繁殖性能。
[Abstract]:The aim of this study was to investigate the effects of perilla seed extract on the performance, hormone level and reproductive performance of Rohmann egg broiler at the late stage of egg production. A total of 1 080 49-week-old healthy Rohmann fowls were randomly divided into 4 treatments, each of which was divided into 5 replicates and 54 replicates. The control group was fed with basal diet and the experimental group was fed with 100200300 mg / kg perilla seed extract in the basal diet for 40 days. The results showed that the addition of 300 mg/kg perilla seed extract to the diet could significantly increase the laying rate and the average daily egg production (P0.01), compared with the control group. Addition of 100200300 mg/kg perilla seed extract significantly increased the levels of progesterone (20 days) and estradiol (20 ~ 40 days) in the serum of laying hens (P0. 01), and significantly decreased the serum testosterone content of laying hens (P0. 01) by adding 300 mg/kg perilla seed extract (P0. 01). The addition of 300 mg/kg perilla seed extract could significantly improve the egg qualification rate, fertilizing rate and hatching rate, and decrease the death rate of Amoy (P0.05). It can be seen that the effect of adding 300 mg/kg perilla seed extract to the diet of egg breeding chicken at the late stage of egg production peak can improve the performance and reproduction performance of egg breeding chicken.
