The effect of supplementation of feed with exogenous enzymes on the growth of common carp (Cyprinus carpio)
Supplementary feed exogenous enzymes have improved the growth rates of various food animals. In thisresearch, the effect of Endofeed W, a multienzyme feed supplement, was investigated on the growth of carp.Accordingly, 134 fish (33.1 ± 0.8 g) were randomly allocated to 4 experimental groups. During the first stageof the experiment (10 days), groups 1-3 received 1, 2 and 3 g Endofeed W per kg di...
متن کاملAcute toxicity effect of glyphosate on survival rate of common carp, Cyprinus carpio
Background: Herbicides are usually used to control weeds and some of them like glyphosate are nonsele ctive herbicides. Aquatic environments are usually the last destinations of agricultural pesticides, which disrupt the metabolic processes of organisms. Thus, the aim of this study was to evaluate acute toxicity of glyphosate on the survival rate of common carp, Cyprinus carpio. Methods: A to...
