How to raise sheep in captivity

The sheep raised in captivity have the advantages of fast growth, early fencing, good fat condition, high meat yield and good economic benefits. So how to raise sheep in captivity?

(I) Construction of sheep sheds

The sheep house is built with a single slope open shed or a fully enclosed type. The height of the rear wall of single slope open shed is 1.8 meters, and the inclination of the roof is 15 °. The fully enclosed wall is 2.3 to 2.5 meters high and the door is 1.5 to 2 meters wide. The floor of the sheep house is 20cm to 30cm above the ground outside the house and is paved with a slope to facilitate drainage. Generally speaking, each adult sheep accounts for about 1.5 square meters, while pregnant ewes, lactating sheep and breeding rams account for a slightly larger area. The house should be kept dry and ventilated, warm in winter and cool in summer as far as possible, with a sports ground outside the house, with an area of about 2 times the area of the sheep house.

(2) production of roughage

Cut down the harvested corn straw and dry it for a day, turning it to 0.5.

1. Straw silage ~ 2 cm post-node silage.

two。 Microbial fermentation spray wet mixing crushed crop straw or agricultural by-products such as wheat straw, corn straw, peanut seedlings, peanut shells, corncobs, etc. are packed in vats, barrels or plastic bags, and then eaten after anaerobic fermentation.

3. The feeding method is feeding, feeding twice a day, the water in the sink can not be cut off, pay attention to the change of water every day. At the same time, concentrate was properly supplemented according to different growth stages of sheep. In general, the ratio of straw forage to concentrate of fattening sheep was 4 ∶ 1, that of pregnant sheep was 5 ∶ 1, and that of breeding ram was 4 ∶ 1.

According to the composition of wool fiber, wool can be divided into fine wool, semi-fine wool and coarse wool. Fine wool, from the appearance, shorter than other kinds of fiber, bending more and more obvious, textile value is the highest, used in the production of high-grade worsted and coarse textiles. Semi-fine wool, the appearance of bending is less and larger, the fiber is also longer, textile value is also higher, mainly used for combing, knitting and industrial use. Coarse wool, from the appearance, the bending is not obvious, the hair is longer, the textile performance is poor, mainly used for weaving carpets and felt.
