Abstract:With the further advancement of grassland vegetation and ecological environment protection, and the implementation of returning grazing land to grassland and returning farmland to forestry, traditional sheep farming has gradually transformed from freerange nomadic herding to housing breeding. In recent years, Guazhou County has relied on the advantages of abundant crop straws and agricultural and sideline products, and has actively promoted regional production layout and improved varieties in accordance with the development idea of "building gardens to expand the scale of farms, synchronously developing largescale retail farms, and raising the level of standard breeding". Integrated population breeding, comprehensive forage utilization, and industrialized production and operation have established a production pattern of "expanding the breeding scale in the southeastern townships and focusing on forage fattening in the western townships." We promote standardized production, utilization of straw as feed, and allinone breeding model. At present, the number of sheep raised in the county has reached 1.1527 million, and the income from breeding industry has reached 342.5 million yuan. The per capita net income of farmers from raising sheep is 1,420yuan, accounting for 13.5% of the per capita net income of farmers. This has increased farmers' income, played an important role in the sustainable development of agricultural and rural economic and social development, and achieved good social and economic benefits. Due to the change in feeding methods, the cost of breeding will inevitably increase. Only by mastering the key points of scientific fattening techniques for fattening lambs. Only in this way can the quality of mutton be guaranteed and the maximum economic benefits can be achieved.
