In total, 240 three-weeks-old sexed birds (191.06±6.01g), 120 + 120 from Lakha, Mushki, Peshaweri and Mianwali varieties of local Aseel were used to determine the influence of selenium forms on growth during three growth phases. Birds were divided into four equal groups, 60 birds/variety (30 + 30), further subdivided into A, B and C treatment groups, 10 bids/treatment. Each group was allocated starter, grower and finisher diets. Group A was offered the diet supplemented with 0.3 ppm Se-enriched yeast and the diet of group B included 0.3 ppm sodium selenite, while group C was fed with un-supplemented control diet. Birds were maintained individually for 18 weeks. Feed intake was decreased, while, body weight gain, feed conversion ratio (FCR) and body weight gain were improved in males and females of Lakha, while best results detected in males during all growth phases in Se-enriched yeast fed groups. In conclusion, Se-enriched yeast had the positive effect in improving growth parameters of native Aseel.
