Rice bran is a by-product of processed rice. It is also a common feed for farmers and some pig farms. The proportion in feed is generally 10% to 30%. However, some pig farmers are arbitrarily increasing their consumption in order to reduce costs. However, this is not only a waste of feed resources but also many adverse effects.
First, the nutrients cannot be completely absorbed. The crude fiber of rice bran is about 9.4%, which is 5.7 times that of corn. Because of the high crude fiber content, pigs can't digest and use the feed of high crude fiber. According to relevant information, there are too many rice bran in pig feed (more than 40%). It will inevitably consume more digestive juice and cause waste of digestive juice. In addition, it will also affect the absorption of other substances. For example, some digested foods are easily absorbed by excess rice bran and the intestinal mucosa cannot be absorbed. At the same time, the rice bran is covered on the surface of the mucous membrane to affect the absorption of other substances, which will not only make the excess rice bran. Can not be completely absorbed, but also caused waste of other feed resources.
Second, excessive addition of rice bran will result in low nutrient content of the feed, reduced feed digestibility, and delayed pig slaughter, resulting in reduced utilization of the pens.
The third is to cause constipation in pigs. Because the rice bran fiber is too high, the enamel is dry, difficult to digest, and absorbs too much water in the intestine. If the feed is too much, and the lack of drinking water and poor management, it is easy to cause constipation in pigs.
