Biochemical and molecular study on Selenium

The experimental work was planned to evaluate the effect of overdose of selenium on performance of growing New-Zealand White female rabbits. The study estimated daily feed intake and weight gain and feed efficiency and conversion; some parameters indicatiA total number of forty eight weaned New-Zealand White Female rabbits of 30 days of age were used in this study.Animals were healthy and clinically free of external and internal parasites.
