四川丘陵地区农村养猪模式的研究

在四川西北部丘陵地区的三台县西平镇进行改进农村传统养猪模式的试验研究。通过连续3年的试验研究，经改进后的生态养猪模式“种—养—沼气生态型”、“种—养—加—沼气生态型”、“种粮—养蚕—养猪—沼气生态型”取得了明显的社会效益、经济效益和生态效益。节约了饲养成本8.85％，日增重提高10％。同时避免了农民大肆砍伐林木的现象，解决了农村生活用能，保护了农业生态环境平衡。

STUDY ON PIG-RAISING PATTERN IN THE HILLY REGIONS OF SICHUAN

Trials were conducted in Shantai County, a hilly area in northwestern Sichuan.to improve traditional pig-raising patterns. As a result of three years'experiments, the following patterns are recommended: crop-growing-pig-raising-methane-generating ecotype,crop-growing-pig-raising-processing-methane-generating ecotype and crop-growing-sericulture-pig-raising-methane-generating ecotype.The application of there improved patterns can save 8.85% of the cost,increase the daily weight gain of pigs by 10% and provide farmers'family with energy for daily life use without cutting wood, which means the ecological balance can be better preserved.
