There is a relative lack of green and green feed in winter and spring. Most farmers generally use coarse crops such as crop stalks and hay to feed livestock. In order to increase the value of feed, the processing and feeding techniques are described as follows: chopped and roasted, no material and fat. As the saying goes: “The three blades of a straw are used, and there is no material.†The coarse part of the lower part of the straw should be cut to make fuel. The upper part of the straw can be cut into about 3 cm for feeding cows and cut into about 1.5 cm for feeding the horses. Animals and sheep. If it is used for feeding pigs, it should be crushed with a pulverizer. To feed livestock with a clam shell, the clam shell can be fried in a large pot until it turns yellow, and then crush it and feed it. Feeding large livestock can not be crushed, but not only can increase the palatability after the roasted and roasted, but also can prevent the livestock from getting cold after diarrhea and improve the fattening effect of livestock. Ammonia fermentation, to help digestion, at present, the production of more use of fermentation, alkalization, ammoniation, spraying salt water and other physical and chemical methods of crop straw and wheat straw and other gramineous forage processing, using the treated straw, forage and other feed Feeding animals can effectively improve the digestibility of livestock. If the amount of fresh sweet potatoes, carrots, etc. are mixed at the same time, the digestive effects of livestock will be further improved. The leaves are treasures, and the best livestock feed is most crop straws and all kinds of hay. The leaves contain more nutrients than straw, but the leaves can easily fall off and be discarded. The content of digestible protein in the leaves of alfalfa hay is more than 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, and the crude fiber content of the leaf is only 1/3 of the stem. Therefore, special care must be taken when processing and feeding, minimizing blade loss and discarding. Peanut vines, yellow bean leaves and sweet potato leaves are most likely to fall off. Attention should be paid to preservation, so that livestock can eat hay and straw with more leaves. Coarse and coarse collocation, effect plus, roughage, especially straw and oyster shell, less net energy content, larger volume, is the basic feed for growth, fattening, labor, milk production, but feeding these feeds can not meet the nutrition of livestock. Need to be fed a certain amount of concentrate, such as cornmeal, cake feed and bran, etc., can effectively improve the growth of livestock. Coarse and rough match, prevent disease and stomach, feed the animals for roughage, but also pay attention to the use of adjustment, do not use a single forage to feed livestock. In particular, single crop stalks, such as straw, wheat straw, and other crude proteins, calcium, and phosphorus, cannot meet the nutritional needs of livestock and should be fed with legume stalks containing more protein and calcium. Utilization of feed. Long-term feeding of livestock with wheat straw can cause cows and sheep to have rumen retardation disease and equine animal dyspepsia. If fed together, it can not only meet the nutritional needs, but also promote gastrointestinal motility, play a role in preventing disease, aid digestion, and make the spleen and stomach function. Green and coarse, with complete nutrition, general carotene content in the roughage is less, phosphorus content is also very low, while the content of green succulent feed and germinating feed is higher, calcium and phosphorus content in bone meal is higher. Therefore, when feeding animals in winter and spring season, appropriate amounts of bone powder, green and juicy feed such as cabbage leaves, radish sprouts, carrots, and sprouted feed should be supplemented to meet the nutritional needs of livestock and promote the healthy growth of livestock.
