An experiment was designed to investigate and compare the effect of organic and standard inorganic selenium in a diet on daily weight gains and food utilization of growing pullets. Pullets, 9 weeks old, were divided into 2 groups of 80 chicks each with 4 replication of 20 chicks per replication. The first group fed diet mixture with standard inorganic form of selenium and was control for the second group whose diet contained organic form of selenium. Diets of the experimental groups were isonitrojenic and isocaloric and differences were only in the forms and content of selenium. The results from this study show that organic selenium, in the form of selenized yeast, was more effective than inorganic form.
