Popis: A study was conducted to determine the effect of feeding with diets containing kefir on growth performance and fatty acid profile of rainbow trout (Oncorhynchus mykiss). Four isonitrogenous (450 g protein kg(-1)) and isocaloric (4325kcalkg(-1)) diets were prepared in trout feed to contain 0 (control), 20, 50 and 100 g kg(-1) kefir. Fish, initial weight of 46g, were randomly distributed into triplicate 520-L fibreglass tanks in freshwater flow-through system. Fish were fed at 4% of the body weight thrice a day for 12weeks. The results indicated that survival rate ranged from 97.14 to 100% without significant difference among treatments (p>.05). Whole-body moisture and lipid composition were significantly affected by diets containing different levels of kefir (p
