Effect of selenium yeast and vitamin E supplementation on haematology, blood chemistry and thyroid hormones in male goats (Capra hircus)

Effects of selenium yeast and vitamin E supplementation on hematology, blood biochemistry and hormones in goats was studied. 24 male kids (2–3 months age, 6.80±0.20 kg average body weight) were randomly grouped into four groups. Group I (Control) was fed a basal diet (concentrate mixture and oat straw), group II and group III were additionally supplemented with 0.3 mg selenium kg⁻¹DM as Se-yeast, 100 mg of vitamin E as DL-á-tocopheryl acetate, respectively and group IV was supplemented with both for 180 days. Non-significant changes were observed in the hematological and blood biochemical parameters except the activity CK (creatinine kinase), which was decreased (P<0.05) in vitamin E supplemented groups. T₃ was increased (P<0.05) where as concentration of T₄ and T₄: T₃ ratio were significantly (P<0.05) decreased in all treatment groups. It may be concluded that supplementation of selenium yeast and vitamin E increased serum level of T₃ and decreased the CK activity without affecting the blood biochemical parameters in goats.
