Abstract

The stocking density is one of the environment conditions in intensive production models. In the factors that restrict the performance of pigs, the variety factors account for about 1/5, diet and daily management account for about 1/2, the growing environment account for about 1/3. Studies have shown stocking density as one of the environmental conditions, it has a certain influence on the growth performance of pigs. Research have shown that stocking density had a close correlation with performance, immunity stress, meat quality and economic benefits of pigs. In this paper, we discussed the effects of stocking density on behavior, growth performance and reproductive performance, meat quality and healthy of pigs, the growth performance and health of pigs affected by stocking density were discussed in detail from the above aspects.

Key words： pigs; stocking density; performance; stress; healthy
