Özdemir Journal of Animal and Plant Sciences JAPS 20132013/06/01 23 3 821-827 1018-7081 NA <p>The present study investigated the effects of vitamin A and E supplementation in diets of juvenile rainbow trout subjected to two different flow rates with or without flow stress (0.9 and 2.1 l/min, respectively) on growth performance, vitamin A and E concentrations in serum, malondialdehyde (MDA) level in serum as well as plasma SOD (superoxide dismutase) activity. Fish fed with the three experimental diets (30E+A, 60E+A, &ndash;E+A ) during 12 weeks. In the unstressed groups, WG (weigth gain) of fish did not differ among the diets groups (p&gt;0.05). Lower WG was observed in fish fed the vitamin E-free diet in stressed groups (p0.05). In the unstressed and stressed groups, serum vitamin E concentration was lowest in fish fed with A-E diets (p&lt;0.05). In the unstressed and stressed groups, serum MDA (malondialdehyde) level was highest in fish fed the A-E diet (p&lt;0.05). In the unstressed group, SOD activity were similarly affected by 30 and 0 mg/kg vitamin E supplemented diet groups and in both stress conditions plasma SOD (superoxide dismutase) enzyme activity increased in A+60E diet group.</p> rainbow trout, stress, growth performance, antioxidan status Pakistan Agricultural Scientists Forum https://thejaps.org.pk/AbstractView.aspx?mid=2013-JAPS-323
