Abstract: According to the very large population and less cultivated land per capita in China, the developpment of pig raising environmental engineering in our Country should not follow the foreign experiences but take her own way. Author believes that high input and high energy consumption with completely confined and highly densed pig raising model is not fit the Chinese condition. To stress the self-support of pig meat for big cities is provided with potential dangers. The only way of the development of pig raising industry in China is to take the combination road of agriculture and animal husbandry to fully utilize the instinct of the ease of adapting the enviromental conditions of pigs. The targets to measure the pig production are as follows: the benefits of production, pigging rate, survival rate of piglets, daily body weight gain, the ratio of feed to body weight gain, rate of diseased pigs, and rate of dead pigs. It should not use the level of mechanization or the productivity as the targets to measure the development of a pig raising industry.
