Abstract :

Abstract[1] Vitamin D associated with calcium and phosphorus metabolism and they affected on the uptake and deposition minerals in bone. Fish enabled to use only vitamin D3 and Cholecalciferol is added to the diet of fish. This study on 120 fry of rainbow trout with on average weight 3 gr at 8 weeks in 12 tank fiberglass with a density of 10 fish per tank for determined the effect of different levels of vitamin D in calcium metabolism was performed in 9 nutritional dietary treatments and control experiments. Results showed that the level of vitamin D3 in the diet increased phosphorus, calcium plasma, muscle calcium, calcium bony and alkaline phosphatase. In this study, it is going to follow the development of strong bones, reduce the incidence of skeletal malformations, growth performance and better nutrition and eventually producing so good food in human life. * Corresponding authors; [e-mail]
