The roughage is processed to increase its feed value. The processing methods of common roughage for sheep are introduced as follows:
Hay
In the lush grassland, use fine weather, cut grass (grass or wild grass), and dry it on the same day or the next day, and then collect it into hay. Hay requires a moisture content of less than 14%, does not contain impurities such as sediment, and maintains the aroma of green and grass. If the moisture is too high, the forage will be mildewed, coked and deteriorated, and sometimes it will cause a fire due to internal combustion.
Silage
Fresh feed crops, pastures, weeds and leaves are stored in an anaerobic environment, and an acidic environment is produced by microbial fermentation to inhibit the activity of harmful microorganisms, so that the method of preserving the feed is called silage. Silage made from silage is silage. After the silage is made into silage, the feed nutrients can be preserved for a long time, the feed is juicy, and the acidity and fragrance after fermentation can improve the palatability of the feed. At the same time, the nutrient loss during the preparation process is less, and the storage place is not large.
The key to the success of silage is that the environment must be sealed, contain enough sugar and suitable moisture. In order to ensure the tightness, the farmer is better able to prepare a silo kiln, which can be used not only to prepare silage, but also to modulate ammoniated straw. Silage kiln can be made of cement and stone, and the volume depends on the number of sheep. Generally, each sheep needs 300 kilograms of silage in winter and spring, and 750-800 kilograms of feed per cubic meter of silo kiln.
Silage raw materials should be cut short, usually cut into 3-5 cm long, in order to step on. The raw materials in the kiln should be layered until the juice flows out. Finally, the plastic film is used to cover the stone and the stone is pressed up. After a month or so, the kiln can be opened for consumption and can be stored for a long time. If the amount of modulation is not large, the plastic bag can be used for silage, but the plastic bag should be prevented from breaking. The moisture content of fresh crops is generally more than 80% (such as fresh ryegrass, the water content of Chinese milk vetch is as high as 90%), and the water should be adjusted to 65-75% by drying or blending dry straw. The moisture content of the silage material can be judged by experience: after the silage material is cut short, it is kneaded in the hand for 1 minute. If the juice is squeezed out, the water content is generally greater than 75%; if the grass ball in the hand can maintain the shape and no The juice is 70-75%; the grass ball is elastic and slowly spreads, and the water content is 55-65%.
In order to improve the nutritional value of silage, a certain amount of nutrients can be added to the silage raw materials, such as adding 0.5% urea to corn stalk and sweet potato vine, adding 5-10% rice bran to Chinese milk vetch, which can improve silage Quality; adding 1% salt can improve the palatability of the feed.
Silage feed sheep should be from less to more, let the sheep gradually adapt, and feed with hay and concentrate, do not feed more than 2 kg per day. Overfeeding of the ewe's silage in late pregnancy can cause miscarriage. Silage feed must be taken in the process of taking it, not a lot of it at once, otherwise it will quickly deteriorate and rot, and should be sealed in time after taking the material.
Solar road light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery, gel battery) to store electrical energy, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps.
