The roughage has been processed to improve its feed value. The sheep's commonly used roughage processing methods are described below:
hay
In the flourishing days of green grass, using fine weather, weeds (grass or wild grass) are harvested and dried on the same day or the next day. Hay requires moisture content below 14%, does not contain impurities such as sediment, to maintain the green and green grass aroma. If the moisture is too high, the forage will mold, coke, and deteriorate, and sometimes it will cause a fire due to internal combustion.
Silage
Fresh forage crops, pastures, weeds, and leaves are stored in an anaerobic environment, which produces an acidic environment through microbial fermentation and inhibits harmful microbial activity. The method of preserving the feed is called silage. Silage made from silage is silage. After the silage is made of silage, the feed nutrients can be preserved for a long period of time to maintain the succulence of the feed, and the fermented acid and aroma can be used to improve the palatability of the feed. At the same time, there is less nutrient loss in the process of modulation and the storage site is not large.
The key to the success of silage is that the environment must be confined, containing enough sugar and suitable moisture. To ensure airtightness, it is advisable for farmers to prepare a silo for kiln, which can be used not only to modulate silage but also to modulate ammoniated straw. Silage kiln can be made of cement, stones, and volume according to the number of sheep. In general, each sheep needs 300 kg of silage for winter and spring, and 750-800 kg of feed for every cubic meter of silage.
Silage raw materials should be cut short, generally cut into 3-5 cm long, in order to step on. The raw materials in the kiln should be compacted until there is a flow of juice. Finally, the plastic film is used to cover the stone and press the stones. After a month or so, the kiln can be eaten and it can be stored for a long time. If the amount of brewing is not large, use plastic bags for silage, but prevent the plastic bag from breaking. The moisture content of fresh crops is generally more than 80% (such as fresh ryegrass, milk cloud, the water content of up to 90%), should be used to dry the air or mixed with dry straw and other methods to adjust the moisture to 65-75%. The moisture content of the silage raw material can be judged by experience: After the silage material is chopped, it is kneaded in the hand for 1 minute. If the juice can be squeezed out, the moisture content is generally greater than 75%; if the grass ball can keep the shape and no The sap is 70-75%; the grass ball is elastic and spreads slowly, with a moisture content of 55-65%.
To increase the nutritional value of silage, a certain amount of nutrients can be added to silage materials, such as 0.5% urea in corn stover and sweet potato vine, and 5-10% rice bran in milk vetch, which can increase silage Quality; adding 1% salt can improve feed palatability.
Feed the sheep from silage to more, so that the sheep gradually adapt to, and feed with hay, fine feed, feed no more than 2 kg a day. Late feeding of hens in the late pregnancy can cause miscarriage. Silage in the process of access must be taken now feed, can not take a lot at once, or it will soon deteriorate, rot, pick up after the timely sealing.
