Rice bran is a by-product processing of rice, farmers and some commonly used Feed, pig farms in the ratio of the Feed is commonly 10% ~ 30%. But some farmers in order to reduce costs and increase dosage of its random, but this will not only waste the Feed resources bring many adverse effects.

One is the nutrients can be fully absorbed. Rice bran crude fibre is approximately 9.4%, 5.7 times that of corn, because the crude fibre content is high, and the pig can't digest, the use of high crude fiber Feed, according to the relevant information, when the pig Feed too in rice bran (over 40%), and will consume more digestive juices, the waste caused by digestive juices. Also can affect the absorption of other substances, as some have been digested food is easy to be redundant rice bran adsorption and make the intestinal mucosa to absorb, rice bran and coating in the mucosal surface at the same time so as to affect the absorption of other material, it not only can make extra rice bran could not be fully absorbed, also caused other Feed the waste of resources.

Second, excessive add rice bran can cause low Feed nutrition, Feed digestibility, pigs are delayed, resulting in the housing lower utilization.

Three is pig constipation. Due to excessive coarse fiber from rice bran chaff and dry, hard to digest, excessive moisture within the intestinal absorption, if there is excessive feeding plus water insufficient and poor management, easy to cause constipation.
