采用单因素试验方法,研究了不同饲养方式及密度对产蛋期绿壳蛋鸡行为学的影响.试验选择生长发育正常的产蛋期绿壳蛋鸡7 500只,随机分成笼养高密度组、笼养低密度组和散养组.结果表明,散养组蛋鸡的啄羽现象、攻击行为、刻板行为都明显低于笼养低密度组和高密度组,而这些行为在高密度组非常严重;散养组蛋鸡的觅食行为、修饰行为都明显多于笼养低密度组和高密度组.结果显示:不同饲养方式及密度对于蛋鸡不同的行为参数有明显影响,过高密度的饲养会严重影响绿壳蛋鸡的行为表现.

Based on the single factor experiment method, it is studied the effects of different rearing patterns and densities on animal behaviors in laying hens. In this study, 7 500 green-shell laying hens were randomly assigned into a free range group and 2 caged groups with low-density or high-density housing. The results show that the dispersion phenomenon, aggressive behavior and stereotyped behavior of laying hens in free range group were significantly lower than low-density group and high-density group, and the high-density group was more serious, and the foraging behavior, behavior modification of laying hens in free range group were significantly higher than low-density group and high-density group. These results indicate that different rearing patterns and densities have obvious influences on the behavioral parameters, and the increase of rearing density will seriously affect the animal behavior in laying hens.
