Cottonseed,as a high-quality protein source,has the advantages of wide availability,rich nutrition and low price,and its application in China's livestock and poultry production is becoming more and more widespread. However,if cottonseed （meal） is not used properly in the diet,it is easy to cause gossypol poisoning in animals.For dairy cows,the migration of gossypol into milk not only involves the metabolism of gossypol by ruminants but also the quality and safety of dairy products,thus it should be given due attention.Based on this,the paper conducted a safety assessment of gossypol residues in raw milk by adding cottonseed to the diet on raw milk. The amount of free gossypol ingested by the human body through drinking milk was 0.002 3 mg/kg·d,which is far below the limit value of 0.086 mg/kg·d for free gossypol intake through vegetable oil in the GB 2716-2018 National Food Safety Standard for Vegetable Oils.
