Nonetheless, it is widely assumed that we can deduce something about the need for continuing or stopping VAS programs based on studies of the biochemical prevalence of vitam...
متن کاملEffect of Rearing at Different Densities and Dietary Supplementation with Vitamin E on Growth Indices, Survival and Carcass Composition in Fingerling Rainbow Trout (Oncorhynchus mykiss)
This study was conducted to investigate the effect of rearing at differing densities and dietary supplementation with vitamin E on growth indices, survival and carcass composition in fingerling rainbow trout in a 6-week trial. Rainbow trout juveniles with initial body weight of 9.6 ± 0. 69 g at two densities of 50 and 100 pieces per 50 liter were fed two diets with the same protein and fat cont...
