Tofu residue is the residue obtained when making tofu with soybeans as raw materials. The water content of fresh bean curd residue is as high as 78% ~ 90%; The contents of protein and crude fiber in dry matter are relatively high, which are 265,438 0.7% and 22.7% respectively, and most vitamins are transferred to soybean milk. Bean curd residue also contains trypsin inhibitor, which needs to be cooked before use. Fresh bean curd residue can be used as compound feed raw material after drying, but the processing cost is high, and it is often fed directly with fresh bean curd residue.

Bean curd residue is a cheap protein feed and roughage resource, which is worth developing in resource-rich places. It is best to use it after artificial dehydration and high temperature detoxification, so that the dosage can be increased to more than 30%.
