Abstract
The aim of this study was evaluate the effects of dietary vitamin E on growth factors, survival, reproductive performance and sex ratio in guppy. Guppies were divided into 5 treatments with triplicate groups and fed with one of 5 diets for 20 weeks. The experimental vitamin E diets were formulated to contain 100, 300, 500 and 1000 mg kg-1 vitamin (treatment 1, 2, 3 and 4 respectively) with 1 control group (Treatment 5). The data obtained from the trial were subjected to one-way analysis of variance (ANOVA) to test for effects of dietary treatments. In vitamin E treatments the body weight increase (BWI), percent body weight increase (PBWI), specific growth rate (SGR), daily growth rate (DGR) and reproductive performance of guppies were increased significantly with increasing the amounts of vitamin E (P<0.05) and highest BWI, PBWI, SGR and DGR were observed in treatment 4. There were no significant differences observed in survival rate and sex ratio between the treatments. This study indicates that BWI, PBWI, SGR and DGR and reproductive performance can be improved by dietary vitamin E supplementations and also may be concluded that the vitamin E requirement of guppies fish for optimum growth and reproductive performance is 1000 mg kg-1 of dry diet.
