Okara is a by-product of the processing of soy products from soybeans. According to the measurement, fresh bean dregs contain 4.7% crude protein, dry bean dregs contain 27.7% crude protein, and crude fiber content is about 6%. It is an ideal feed for pigs in rural areas. However, feeding pigs with bean dregs should not be directly fed. This is because the okara contains anti-trypsin, which can inhibit the decomposition of legume protein in pigs and affect the growth of pigs. Heating the bean dregs for 15 minutes before feeding the pigs can destroy the antitrypsin, so that the protein in the feed can be fully utilized. Conditional pig farmers can also ferment the bean dregs and feed the pigs. scE China Feed Industry Information Network - based on feed, serving animal husbandry

The proportion of bean dregs in the diet of pigs should not be too high, because the crude protein content in the bean dregs is low, the quality is poor, and the vitamins are lacking. The mineral content is also very small. It must be combined with other feeds to meet the nutritional needs of pigs. . The suitable amount of bean dregs in the pig diet is: the ratio of fresh bean dregs is controlled at 25%-30%, and the proportion of dried bean dregs is controlled below 10%, otherwise it may cause indigestion in pigs. scE China Feed Industry Information Network - based on feed, serving animal husbandry

In addition, fresh bean dregs contain more than 80% water content. After being placed for a long time, it is easy to spoil and deteriorate. After feeding pigs, it will cause pigs to be diarrhea and even poisoned. Therefore, it should be kept fresh as much as possible. If there is mild sourness, add 50g of lime powder or baking soda to each kilogram of bean dregs to mix evenly to neutralize the organic acid and improve the appetite of the pig. Seriously rancid and deteriorated bean dregs are prohibited from feeding pigs. If the bean dregs can not be fed for a while, you can add a small amount of salt to preserve the antisepsis, or you can dry it. scE China Feed Industry Information Network - based on feed, serving animal husbandry
