Rice bran is a by-product of processing rice using rice and is the most common feed for pigs. However, the use of rice bran to feed pigs should pay attention to the following four questions: First, limited feeding. In pig diets, the amount of rice bran should be between 25% and 30%, not exceeding the 30% limit. If it exceeds the quality of pork, it will produce low-quality soft fat meat, and it will cause dermatitis and embolism; it will make the body condition of pigs too fat, reduce reproductive performance; will cause piglets diarrhea, unfavorable growth and development and so on. Second, do not store for a long time. In high-quality rice bran, the oil content is high. If it is stored for a long time, it will gradually deteriorate and deteriorate, making the nutritional value and palatability lower. Therefore, it is advisable to feed pigs with new rice bran and not store them for a long time. In particular, do not feed piglets with Chen Mihao who has been storing for too long. Third, soak softening. The rice bran is soaked in warm water before it is fed to soften it, improving the digestive capacity of the pig. Soak the water with rice bran. Soaking time is 3 hours in summer and autumn and 4 to 5 hours in winter and spring. Fourth, pay attention to calcium and phosphorus. To use rice bran to feed pigs, in addition to reasonable matching with other fine, coarse, and green fodder to meet the needs of pigs for various nutrients, calcium and phosphorus should also be added properly. This is because the content of calcium in rice bran is low and it cannot meet the requirements of pigs. Although there are many phosphorus contents, it is mainly phosphorus phytate and cannot be fully absorbed by pigs. Therefore, to use rice bran to feed pigs, it is necessary to add 1.5% to 20% of bone meal in the pig diet to supplement calcium and phosphorus in the diet. At the same time, let the pigs get more sun and promote the absorption of calcium and phosphorus.
