Nutrition formula for resisting gossypol-induced fish enteritis, use method, application and feed

The invention discloses a nutrition formula for resisting gossypol-induced fish enteritis, a use method, application and a feed. The nutrition formula for resisting gossypol-induced fish enteritis comprises the following ingredients (by weight): 0.0053-0.013 part of iron, 1.4-2.1 parts of valine and 0.0005-0.0009 part of riboflavin. A fish feed is prepared from the nutritional formula composed of the above ingredients according to the above ratio. When the fish feed is applied to cultured freshwater fishes, gossypol-induced fish enteritis can be effectively prevented, and vacuolation of intestine epithelia, exfoliation of epithelial cells at two sides of plica and flattening of plica top are reduced.
