Answer: It is not appropriate to feed raw tofu with an anti-trypsin, which can hinder the digestion and absorption of protein by trypsin in fish. Therefore, before boiling, the bean curd residue is heated and boiled for 15 minutes to destroy the antitrypsin, thereby making full use of the protein in the feed. It is not appropriate to feed too much suitable amount of feed: fresh slag in the diet is controlled at 25% to 30%, and dry residue is controlled at 10% or less. If too much, it will cause fish indigestion and other symptoms. The rubbish residue that is not suitable for feeding spoilage is seriously degenerated. The inclusion of toxic substances such as aflatoxin in fish poisoning is likely to cause death from fish poisoning and should be prohibited. 100% Cotton Polo Shirt,Cotton Polo Shirt,Black Polo Shirt,Man'S Polo T Shirts Xinhui Jielide Garment Factory , https://www.ntgfwear.com
