The results showed that the lamb meat of Dazu black goats was dch in nutrients, fresh, tender, palatable and fine in texture as well as non-hazardous in quality. Thus, the meat of Dazu black goat is a kind of healthy and nutritious food with rich nutrients, and it has better prospects of exploitation and utilization in the food industry.展开更多

A campaign for construction of eco county has been developed all over China since the 1990s. It is aimed to enhance sustainable development capacity of the county by establishing ecologically sound production system and management mechanism through eco engineering, eco planning and eco management. It is a complicated systems engineering and a combination of multi disciplinary and needs the most extensive participation of decision makers, technicians, and farmers. Construction of eco county consists of many important works such as survey, systems diagnosis, planning, demonstration, implementation and assessment. In this paper, we will try to summarize the current status, main models in different regions, procedure of construction, and introduce the eco agriculture county construction in detail by taking Dazu County of Sichuan Province as an example.展开更多
