Coarse and fine with: roughage, especially straw and oyster shell, less net energy content, larger volume, is the basic feed for growth, fattening, labor, milk production of livestock. However, feeding only these feeds can not meet the nutritional needs of livestock, must feed a certain amount of fine materials, such as cornmeal, cake feed and bran, etc., can be conducive to the growth of livestock. Coarse and rough: If you use roughage to feed livestock, also pay attention to the use of the transfer, do not use a single forage to feed livestock. Long-term feeding of livestock with wheat straw can result in rumen-delayed disease in cattle and sheep and indigestion in horses. If fed together, it can not only meet nutritional needs, but also promote gastrointestinal motility, prevent disease, help digestion, and strengthen the spleen and stomach. Green and coarse: In general, the content of carotene in the roughage is low, and the content of phosphorus is also very low. The content of carotene in the juicy green feed and germinating feed is higher, and the content of calcium and phosphorus in the bone meal is higher. Therefore, when feeding animals in winter and spring season, appropriate amounts of bone meal and green and blue succulent feeds, such as cabbage leaves, radish sprouts, carrots, and sprouted feed, should be supplemented to meet the nutritional needs of livestock. Chopped and chopped and roasted: The coarse part of the lower part of the straw should be cut to make fuel. The top part of the straw can be cut and grown to about 3 cm for feeding the cows; cut about 1.5 cm to feed the horses and sheep and so on. 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 cool diarrhea of ​​the livestock after cooling, and improve the fattening effect of livestock. Fermentation and ammoniation: At present, physiochemical biological methods, such as fermentation, alkalization, ammoniation, and spraying of salt water, are used in the production to treat grass crops such as crop straws and wheat straw, which can effectively improve the digestibility of livestock. If you mix a suitable amount of fresh hawthorn and carrot at the same time, the digestion effect of livestock will be further improved.
