Exploring the effect of selenium forms on final body weight, slaughter characteristics and tissue selenium concentration in Aseel cockerels

A study to investigate the influence of selenium on final body weight and slaughter traits of Aseel was conducted. Three-weeks-old 120 cockerels from Lakha, Mushki, Peshaweri and Mianwali varieties of Aseel were randomly selected and distributed into four groups, 30 cockerels each, subdivided into 3 treatment groups A, B (experimental groups), and C (control group) with 10 cockerels in each treatment. Birds were assigned three experimental diets. The diet for the birds of group A incorporated 0.3 mg/kg Se-enriched yeast and group B included 0.3 mg/kg sodium selenite, while C was fed the diet without Se (control diet). Final body weight, dressed weight, dressing%, eviscerated weight, eviscerated%; chest, thigh and giblets weight; selenium content in chest and thigh in Se-yeast fed birds were significantly increased than those got sodium selenite or control diet. The study concluded that Se-enriched yeast is more effective in improving body weight and slaughtering characteristics of Aseel.
