Rice bran, commonly known as barley, is a mixture of peel, seed coat, and embryo removed during the processing of brown rice, which also contains a small amount of rice hulls, broken rice, and so on. Rice bran contains crude protein 11.5%-14.5%, oil 10%-18%, and rich in vitamin B and manganese, potassium, magnesium, silicon and other minerals, but vitamin A, vitamin C, vitamin D content is less. Rice bran is a good feed for farmers to raise pigs, but the traditional usage is not reasonable and should be improved. 1, right amount. Excessive feeding of rice bran will result in overweight of the pig's body, which will reduce breeding performance of the breeding pig. In addition, because the higher content of phytate and trypsin inhibitors in rice bran is not conducive to the decomposition of crude protein, pigs consuming too many rice bran will diarrhea, so the amount of rice bran should not exceed 30% of the pig diet , and should be reasonable with other fine, coarse, green feed. 2, fresh. Rice bran has a high content of oils and is easily acidified and deteriorated by high temperature, humidity, light, and air during the storage process, which reduces the nutritional value and palatability of the diet and may cause diarrhea in piglets. Therefore, Chen Mihao, who has been stored for too long, should not be used to feed piglets. 3, add calcium and phosphorus. Rice bran contains less calcium and can not meet the nutritional needs of pigs. Although there are many phosphorus, but mainly phytate phosphorus, can not be fully absorbed and utilized by pigs. Therefore, the pig diet added with rice bran should be added 1.5% -2% of bone meal, while letting the pig more sun, in order to promote the body's absorption of calcium and phosphorus.
