Method of feeding chicken with rice bran
Rice bran is the main by-product of rice processing, which is generally used as feed for poultry and livestock, so what is the method of feeding rice bran to chickens?
What is rice bran?
Rice bran is the rolled product in the process of rice whitening. at present, rice bran is mainly made from pericarp, seed coat, endosperm, aleurone layer and embryo. Rice bran is rich in various nutrients and physiologically active substances, which can be used as feed or further processed into edible rice bran.
Medical research shows that rice bran oil has the functions of clearing cholesterol in blood, reducing blood lipids, promoting human growth and development, and has certain medicinal value, and is recognized as nutritional and healthy oil at home and abroad. Rice bran oil is easy to absorb and the absorption rate is more than 90% after eating.
Second, the method of feeding chicken with rice bran
Rice bran can be mixed with feed and water to feed chickens. When feeding chickens, we should also pay attention to the amount of rice bran. In general, in the diet of adult chickens, the amount of rice bran is less than 10%, while in the diet of chicks, the amount of rice bran is about 5%.
Generally speaking, the rice bran used in animal husbandry mainly includes full-fat rice bran and defatted rice bran. Defatted rice bran refers to the extraction of fat from rice bran, that is, rice bran oil, generally in order to reduce the rancidity of rice bran fat and prolong the storage life. Rice bran is rich in nutrition, is a better energy feed, and the price is lower than corn and wheat bran.
The study showed that for 21Mel 49-day-old broilers, the feed intake was not significantly affected when the amount of rice bran used in the diet was less than 20%, while other experiments found that for 10-49-day-old broilers, the feed conversion rate did not change significantly in the range of 0-53.9%, but the growth rate slowed down significantly.
When the amount of rice bran reaches 38.5%. Compared with 18.5% rice bran diet group, although the crude protein level was the same and the energy was slightly higher, the egg production and egg weight of laying hens decreased significantly.
Therefore, we must pay attention to the amount of rice bran to feed chickens.
