Feeding management is grazing once a day in the morning and afternoon. Feed the bean straw-fresh grass-fine concentrate before grazing in the morning, and feed the formula concentrate at night, and drink freely. The fattening sheep are 12 to 14 months old rams, each of which covers 1 square meter. The house is cleaned twice a day and sleeps on the mattress. Each sheep of the feed is fed 2 kg of winter grazing 70 ryegrass per day, and the dried bean stalks are freely eaten, and the formula concentrate is 0.5 to 1 kg. The formula has 14.70% digestibility, 14.40% crude protein, 0.75% calcium and 0.42% phosphorus. Among them, corn 59%, wheat bran 20%, cottonseed cake 10%, bean cake 3%, dried amorpha leaf powder 5% and premix 3%. After 45 days of fattening, the fattening effect can be increased by more than 4.70~11.44 kg, the net meat rate can be increased by 4.05%~8.22%, and the fine material fee is only 7.02~34.06 yuan. In addition, in places where there is a shortage of concentrates, weeds can be planted in winter idle land or wasteland, and each day we can feed 2 kg of fresh grass, which can also achieve certain weight gain and economic benefits.
