改善产蛋后期鸡蛋蛋壳质量研究进展

蛋壳质量是评价蛋品质的重要指标,和鸡蛋的运输和保存过程中的破损率相关,且直接与种蛋的合格率、孵化率和鸡苗的健康密切相关,是影响蛋鸡生产效益的要素之一.蛋鸡老龄化是导致产蛋后期蛋壳质量下降的主要因素.特别是近年来,商品蛋鸡的产蛋周期大大延长,蛋鸡老龄化程度更高,这导致产蛋后期面临的蛋壳质量下降的问题更为严峻.本文对蛋壳的...

Research Progress on Improving Eggshell Quality in Late Laying Period

Eggshell quality is an important indicator for evaluating egg quality.It is related to the breakage rate during the transportation and storage of eggs,and is directly related to the pass rate of breeding eggs,hatching rate and the health of chicks.It is one of the important factors affecting the production efficiency of laying hens.The aging of laying hens is the main factor leading to the decline of eggshell quality in the later stages of laying.Especially in recent years,the laying cycle of commercial laying hens has been greatly prolonged,and the aging degree of laying hens has been higher,resulting in a more serious problem of the decline of eggshell quality in the later stage of laying.This article summarized the reasons for the decline of eggshell quality in the late laying period from the eggshell formation process and calcium metabolism process,and summarized and prospected the solutions to improve the eggshell quality in the late laying period.
