1. It is important to select crossbred sheep for crossing with good meat breed sheep and local breeds, and to use the heterosis of the hybrid offspring to improve the economic benefits of the finishing sheep. According to the production experience in different parts of the country, the cross between the Charolais sheep and the Dorset sheep and the local breed sheep of our country were crossed. The growth rate of the lambs was accelerated and the meat quality was enhanced. Zhang et al. (1995) reported that the Dorset lambs and local goats were fattened using different methods of fattening (fattening, grazing, supplemental fattening, and grazing). The growth rate and economic benefits of the hybrid sheep were higher than that of the local sheep. . After a 90-day fattening period, the average weight of the hybrid lambs in the house-feeding group was 15.7 kg more than that of the local lambs, and the average economic income of each hybrid lamb was increased by 17.07 yuan; the average weight of the hybrid lambs in the grazing-plus-replenishment group was 13.3 kg more than that of the local lambs. The increase in the profit of each hybrid was 27.56 yuan; the weight of the hybrid lambs in the grazing group increased by an average of 1.6 kg compared with the local lambs, and the average economic value of each hybrid lamb increased by 8.32 yuan. The slaughter test showed that the meat performance of the hybrid lambs in the finishing groups was higher than that of the local lambs. 2. The use of early lamb weaning, early fattening, proper slaughter due to the lamb's early growth and development faster, fattening effect is better, and choose the best fattening period, improve the economic benefits of fattening. Li Yuge (1994) reported that the small-tailed lambs were weaned for 2.5 months, and they were fattened to 5 months of age under moderate nutrient levels. The highest daily gains were obtained, with the highest feed remuneration and a feed-to-weight ratio of 2.9:1. 3. A reasonable mix of feeds in accordance with the nutritional requirements of the sheep during the fattening period meets the diet, and the fine or coarse material in the diet should be diversified to increase palatability. 4. The application of feed additives and embedding weighting agents can improve the fattening effect. China Agricultural Network Editor
