Adult shelf donkeys refer to male and female donkeys that are older than three or four years old and are eliminated. After the donkey has been fattened, its meat quality is lower than that of young donkeys. The feed reward and economic benefits are also poorer than those of young donkeys. However, after fattening, economic value and food value can still be greatly improved. The fast fattening of adult shelf donkeys is divided into two phases, and the time is 65-80 days. Mature fattening period is 45-60 days. This period is a crucial period for donkey fattening. To limit its movement, increase the concentrate (crude protein content is higher), increase the number of feedings, and promote the growth of maggots. The strength of fattening period is generally about 20 days. The purpose is to improve the quality of the donkey meat by increasing the amount of fat deposits between the muscle fibers so that it forms a marbled lean meat. During this period, the dietary concentration can be appropriately increased to try to increase the feed intake of the donkey. Defenders of adult shelf donkeys must strengthen feeding and management. The male donkey must be castrated. The donkey for fattening should be dewormed, fed with high-quality fodder for forage, reduce the movement, and pay attention to the hygiene of shacks and donkeys. If a donkey is newly purchased from the market, it will take 15 days to adjust to reduce stress. The newly purchased donkey should drink more water, give more grass and less feed, and then start feeding a small amount of concentrate three days later.
