The right amount of rice bran in the pig diet can reduce the cost of feeding. The amount of pregnant sows in the early stage is 20%~30%, the middle period is 30%-70%, and the late 30%-50%; before the 30-60 day old pigs to 30kg, it should be 5%-15%. If the dosage is too much, Piglets do not like to eat, and will cause squatting; 30-70kg shelf pigs, dosage 10% -20%; 70kg or more finishing pigs, the dosage should be 20%-25%. Within 25% of the dosage, the feed value is equivalent to corn. When the dosage is more than 30%, the feeding value is lowered, the pigs start picky eating, the appetite is lowered, the skin is slack, and the meat quality of the fat pig is lowered.
