Selenium supplementation to broiler diets

The present study was conducted to determine the effect of selenium supplementation on performance of broiler chicks. 300 broiler chicks (Lohmann) were divided into three groups of equal weight and numbers. Group (A) fed on broiler diet, group (B) fed on broilers diet + 3% vegetable oil and group (C) fed on broiler diet + 3% vegetable oil + 0.12S ppm Selenium. Feed intake, body weight, weight gain, feed conversion ratio, respiratory rate, body temperature and some carcass characteristics were examined for the significance of effect of diet treatment using one way analysis of variance. Feed intake was not affected by dietary treatments, however, body weight was Significantly (P<0.05) increased in group Band C, compared to group A. Carcasses analysis showed no significant variations among dry matter, ether extract and ash for the three dietary groups. For CP, group C was significantly (P<0.05) higher compared to group A and B. Group (B) had Significantly (P
