随着养猪业集约化、工厂化的发展,为了方便管理和降低成本,实际生产中常常扩大饲养密度,导致猪生存空间和食物等不足,诱发猪心理和行为方式等的改变。此外,高饲养密度加大了猪舍内环境负担,使舍内有害气体含量增多,增加了呼吸道和消化道疾病发生的概率,严重影响着猪群的健康并制约猪生长性能的发挥。本文就饲养密度对猪群健康和猪舍环境的影响做一论述。

With factory and intensive development of swine industry, in order to convenient management and cost reduction, the feeding craft with high stocking density has been often used, which leads to a shortage of living space and food, inducing many changes in behavior and psychology of pigs at same time. On the other hand, the high stocking density can increase the environmental burden, such as the contents of noxious gases and the occurrence of respiratory and digestive tract diseases. All the problems have impacted on health and restricted the growth performance of pigs. The present paper reviewed the effects of the stocking density on piggery＇s health and environment in the pig house.
