Improvement of dietary N-acetylcysteine on growth inhibition and intestinal damage induced by β-conglycinin in juvenile Chinese mitten crabs (Eriocheir sinensis)

β-conglycinin is a major component of feed allergens that can cause inflammation and dysfunction of intestinal digestion and absorption in fish, but little is known in crab. This study investigated the mitigative effects of N-acetylcysteine (NAC) on growth inhibition and intestinal damage induced by β-conglycinin in juvenile Chinese mitten crabs (Eriocheir sinensis). All three experimental diets contained 70 g/kg β-conglycinin, but with three...
