High-quality rice bran contains crude protein 10%- 13%, crude fiber 13%, calcium 0. 1% and phosphorus 1.3%. Vitamin e and b are rich in content. The energy and digestibility are lower than that of grain feed, but its volume is large, which is beneficial to satisfy the satiety of pigs. Protein, minerals and vitamins are superior to grains, and they are high-quality feed for pigs. Its main disadvantages are high unsaturated fatty acid content, easy oxidation and deterioration, storage intolerance, less calcium and more phosphorus. ?

There are many kinds of rice bran with different nutritional values. ?

Big chaff refers to the rice husk removed from rice by husker, which has no feeding value and cannot be fed to pigs. ?

Jade bran and rice bran are by-products of brown rice hulling production, which belong to high-energy feed, and their digestibility is close to that of corn, and their dosage in compound feed for fattening pigs can reach 25%-30%. ?

Copper coin is a mixture of jade chaff and big chaff. ?

Panax notoginseng bran is a mixture of 30% jade bran and 70% big bran. ?

Baer bran is a mixture of 20% jade bran and 80% big bran. Its nutritional value is as low as that of Panax notoginseng bran, and it should not exceed 10% in fattening pig feed, so it can be used as roughage for sows in the second trimester of pregnancy. ?

In rural areas, rice husks are directly processed into rice by rice threshers, and at the same time, direct rice chaff is produced, including rice chaff powder, jade chaff and broken rice. 25-27 kg of straight bran can be obtained per 100 kg of rice, and the nutritional value is slightly lower than that of jade bran. It has been widely used in sow feed with good results. ?

Taking rice bran as an example, the proportion of rice bran in various pig compound feeds is briefly introduced as follows:

20%-30% for sows in early pregnancy; 30%-70% in the medium term; Late 50%-30%; Breastfeeding 30%. ?

Piglets aged 60 days to 30 kg should be around 1%-5%. If the dosage is too much, piglets don't like it, which will cause diarrhea. ?

30-70kg shelf pig, dosage 10%-20%. ?

20%-25% for fattening pigs weighing more than 70 kg. When the dosage is less than 25%, its feeding value is equivalent to that of corn; When the dosage exceeds 30%, its feeding value decreases. Pigs began to be picky eaters, their appetite decreased, their skin became slack, and their meat quality decreased.

Oil bran is the product of rice processing, not outer bran, not inner rice, nor the middle part of rice. It is said that the content of protein is very high, and it is called oil bran if it is not squeezed out. It has a very simple grain flavor and is a good raw material for raising poultry, livestock and fish. Oil bran is divided into rice bran oil (coarse rice bran oil) and bran meal (or bran cake) after being pressed. Crude rice bran oil is inedible and can be further refined into refined oil and by-products. Dandong Xiang Kun Oil Bran Rice Bran!
