Abstract

Pig production plays an important role in farming systems worldwide, especially in subtropical areas. The past few decades have seen significant changes in swine production in such regions. However, there are regional differences in pig production, and some of these are associated with serious problems which impact production systems, the environment and human health. This review introduces the pig breeds, crops and challenge of pig production that faces subtropical areas. A detailed analysis focuses on the control of production problems that are affected by limitations in management and nutritional strategies. Then, factors that drive the major changes in the pig industry in this area are examined in detail, and some insight into pig production directions is provided.
