Rice bran refers to a mixture of fruit peels, seed coats, and germs that have been refined after the rice shell has been dehulled. According to the precision of the processing, the quality varies, and some contain a small amount of chaff and broken rice. Due to the factors in the processing of rice, the moisture content is high. If it is not dehydrated, it is not resistant to storage.

Rice bran is a very good feed for pigs. At 87% dry matter, the crude protein content is about 13%. The energy value is also higher in the woodcutters because the oil content in rice bran is higher than 10%, and some of them reach 18%. %. Most of the fats in rice bran are unsaturated fatty acids, which are easier for animals to absorb and use. The disadvantage is that this unsaturated fatty acid is easily decomposed and deteriorated, so the fresher the better the use of rice bran.

Because rice bran contains higher phytate and trypsin inhibitors that can affect the absorption and growth of crude protein in pigs, it is important to use a good amount of pig feed. Adding too much piglets has diarrhea; it is better to use fewer points when starting to use, and gradually increase the amount of pigs after they are adapted. In the production practice, the maximum amount of fattening pigs is added to 35%. Although the growth is not obviously hindered, it will affect the quality of the meat. It is said that wet heat treatment can destroy trypsin inhibitors and decompose phytic acid, so it can be properly treated. Adding appropriate amount of phytase in compound feed can also neutralize phytic acid in rice bran.

Due to the instability of a large amount of unsaturated fatty acids in rice bran, it is easily decomposed and deteriorated. Therefore, the storage time of rice bran should not be too long, it is best not to exceed two weeks, the more water can not be put for a long time, it is best to buy now is now with the feed, in order to extend the storage period, degreasing treatment can be taken. There are now leaching and pressing methods. Treated oyster cakes can be stored for much longer.

Due to different local appellations, there are about 20% of the total weight of rice shells, rice bran only accounts for 10%, and the rice output rate is about 70%. Therefore, the nutritional content of bran is less than 1/1 of rice bran. 3, in the intensive pig farm is not suitable to use quail, only pregnant sows can be added in small quantities. There are crushed hull processed into a unified wolfberry, this kind of wolfberry can not do pig feed, not only no nutrition, but also Take away some of the nutrients and increase digestion energy.
