In the beginning of spring, there was a lack of green and green fodder, and the countryside generally used hay and crop straw to feed livestock. In order to increase the use value of feed, attention should be paid when using hay processing and feeding livestock: 1. The blades are more important. In various types of hay and straw, the leaves contain more nutrients than stems. For example, the content of digestible protein in the leaves of Takimoza is 3 times higher than that in the stem, 2.5 times higher in crude fat and calcium, and 0.5 times higher in phosphorus. Carotene also mainly exists in the leaf part, but the crude fiber content in the leaves is only in the stem. 1/3. Therefore, care should be taken when handling the preparation to avoid losing or discarding the leaves. 2. Coarse material with good. Roughage, especially straw and oyster shell, has small net energy content and large volume. As the basic feed for growing, fattening, labor, milk production and other livestock, it should be matched with small, high-energy concentrates. However, roughage is still indispensable as a feed for the maintenance of horses and cattle during leisure periods. 3. Do not feed single roughage. Single grasses, such as straw, wheat straw, etc., contain crude protein, calcium, phosphorus, etc., which are unable to meet the nutritional requirements of livestock. They should be fed with protein and calcium containing more legume stalks in order to increase feed intake. Utilization rate. In particular, do not feed the livestock with a single wheat straw for a long period of time. A single wheat straw can make the ruminant livestock have a rumen-relief disease, and the monogastric livestock can suffer chronic indigestion and other diseases. Roughage generally also lacks phosphorus and carotene. Therefore, the amount of bone meal, stone meal, shell powder and green feed should be added when feeding. 4. Straw should be chopped and fed. Before the feeding, the rough part of the lower part of the straw should be cut off. The upper part of the straw can be cut into 3 cm long sections to feed the cows; cut into 1.5 cm long to feed the horses, quail, donkeys and sheep; the feeding pigs must be crushed.
