β-glucan mitigated trinitrobenzene sulfonic acid-induced enteritis in the rainbow trout (Oncorhynchus mykiss)

Enteritis is a common disease in fish which can be induced by a variety of factors. To study the effects of β-glucan on enteritis of rainbow trout (Oncorhynchus mykiss), fish were administrated different β-glucan levels (0, 0.1%, and 0.2%) for 30 days. Then individuals in all groups had enteritis induced with Trinitrobenzene Sulfonic Acid (TNBS) (75 mg per kg of body weight) and were sampled on 3, 6, and 9 days post inflammation (dpi). The growth data showed that 0.2% β-glucan significantly improved the weight gain, specific growth rate, and feed efficiency (p
