This invention discloses the application of β,β-dimethylacrylshikonin in the prevention and control of nonbacterial enteritis in carnivorous fish. Through experiments, the applicant discovered that, under the condition of replacing 50% of fishmeal protein in the feed with soybean meal protein, the addition of shikonin compounds, shikonin alcohol extract, or shikonin ultrafine powder can effectively improve the symptoms of enteritis in pearl grouper, increase the average weight gain rate of pearl grouper, improve the antioxidant capacity of pearl grouper, improve intestinal tissue structure, reduce the transcription levels of pro-inflammatory factors IL1β and IL8 in the intestine, and simultaneously upregulate the transcription level of anti-inflammatory factor IL10. Therefore, shikonin compounds, shikonin alcohol extract, or shikonin ultrafine powder have significant effects on soybean meal-induced enteritis in fish and can be used to prepare drugs or feed additives for the treatment or prevention of soybean meal-induced enteritis in fish.
