During the winter season, the four main points of straw feeding cattle

Straw is a good feed for cattle in winter. However, if the feed is fed improperly, the body will be thin and even die. Scientific use of straw to feed cattle, must grasp the following four points: (A) the selection of high-quality rice straw straw nutrients contained in the leaves, followed by petiole, stems. Therefore, when feeding cattle, try to use straw with more leaves, yellow-green, and soft texture. Straw species must not contain foreign matter such as sediment, plastics, feathers, and metals. Use of straw that has been contaminated with pesticides and mildew should be prohibited to avoid cow poisoning. (2) The reasonable processing of straw-fed cows can be cut into short sections of 3 to 4 cm. It is better to feed the straw after alkalizing, ammoniating, or salinization under certain conditions. Alkalization method: The rice straw is placed in an aquarium or a concrete pond, and immersed in 1% quicklime water or 3% cooked lime water, and then taken out after 24 hours. Amination method: 3% ammonia soaked straw, after 7-10 days, remove the straw to dry, cut short and feed the cattle. Salinization method: add 0.6-1 kg of salt per 100 kg of straw, 150-160 kg of warm water, stir it well, and put it into the cement pool. The beef will be taken out after one day of fermentation. (C) Do not feed straw alone The nutritional content of rice straw is not high. Even if the cattle are allowed to reach the maximum feed intake, they cannot fully meet their nutritional needs. Therefore, a certain amount of green material should be fed or supplemented with some protein-containing fine material. Leguminosae feeding more calcium, can make up for the shortage of calcium in rice straw. Concentrate should be bean cake, corn, sorghum, etc., do not feed too much bran, especially wheat bran contains more phosphorus, long-term feeding is easy to damage the body's calcium and phosphorus balance, resulting in decalcification of bone softening, serious Can cause embarrassment. (4) Reasonable feeding method Feeding cows with straw should pay attention to regular ration, less feeding, proper mixing of straw and sufficient supply of drinking water. If you don't eat, add it to your meal several times. Add fresh grass every time after the cow is finished, until you are full. When supplementing concentrates, the concentrate should be mixed with chopped straw. For this reason, after feeding the forage to the cattle, the cattle must be allowed to drink clean and warm water, and the water temperature should be 15-25°C.
