摘要
饲粮中微量元素的含量及其配比不仅影响着蛋鸡早期的生长、发育 ,还影响到产蛋期的生产性能 ,间接地影响到禽蛋的品质 ,进而影响到消费者的利益。本研究从蛋鸡生产的三个阶段饲粮中微量元素 Fe、Cu、Zn、Mn、Se和 I的最佳供应量及其配比进行研究 ,明显地改善鸡群的健康 ,产蛋率提高了 2 .4 2 % ,产蛋高峰期后延 2 3d。
The quantity and proportion of micromineral in diet affect both the growth of chicken and performance of layer, as well as quality of egg and consumershealth.this experiment was conducted to study the optimum requirement of trace element containing Fe,Cu,Zn,Mn,Se and I on layers during three periods.The result showed that egg productivity was increased 2.42% and the times of egg production peak was prolonged 23d.the health of brids were significantly improved by using the additive.
