Influence of season and breed on serum mineral levels in sheep

The main objective of this study was to assess the concentration various minerals (Ca, P, Mg, Cu, Zn, Fe) in blood sheep, followed by biochemical analysis order reveal possible associations season and breed. conducted sampling four herds: Suffolk (n=20), Merino Lithuanian blackhead (n=20) Charolaise (n=7). first collection April last one performed February. highest level Ca estimated ewes, lowest (12.61%) breed; Mg content found breed, (5.26%) Charolaise; P determined Merino, (24.18%) breed (p⟨0.05). Evalua-tion parameters during different seasons showed a environmental effect on health animals. difference among Ca, Fe autumn, - summer, Cu Zn winter. differences between were observed (1.24-4.03% from total average all seasons) (0.59-8.18%), (2.52-18.36 %) (4.33-24.33%) significance work is use data prevention metabolic production diseases.
