Animal product quality and developmental strategies of animal husbandry in recovery region of Dongting Lake

The animal product quality in recovery region of Dongting Lake was analyzed. The results show that the contents of major trace elements and heavy metals are the highest in cattle liver and the cadmium content is the highest in pig kidney. Under the present feeding conditions, the quality of the major animal meat and egg products are in keeping with the state sanitation standard of non-public hazard on animal products, however the contents of heavy metals, i. e., chromium, cadmium, plumbum, in animal by-products are higher than those of the state sanitation standard of non-public hazard food on animal products. The key measurements of assuring the sustainable development of animal husbandry are to enhance the control and determination of feedstuffs, animal product quality and feeding environments, and encourage the development of non-public hazard, green and organic animal husbandry in the demonstrative region.
