Perfitable animal husbandery and avoid milk production losses need more recognition of metabolic diseases. Among metabolic diseases, disorders related to Ca and P deficiencies in animals especially in sheeps are important. In this relation, it can be referred to diseases such as rickets, reproduction disorders, attenuation of immune drficty. In this investigation, blood samples from 100 apparently healthy sheeps were obtained with venoject tubes in Tabriz, then their ages were determined. Serum of the blood samples were prepared and the serum level of Ca, P, alkaline phosphatase were measured by Biochemistry firmʹs kit in spectrophotomtry method. Study of the mean serum level of Ca and P in different seasons indicates significant reduction in winter. For other seasons, following means of ALP of serums were obtained respectively; 7.05 0.05mg/100 and 4.01 0.03mg/100 (P<0.01), it leads to significant increase in alkaline phosphatase serum level in this season relative to other seasons (P<0.01). It is the result of unavailability of greenland and decrease in sunshine, closed system in winter. In this study, significant reduction in serum level of Ca and P and meaningful increase in sheep more than 3 years (P<0.01). There is a of meaningful correlation between reduction in serum level means of Ca and P and increase in serum, levels of mean of alkaline phosphatase by increasing age (P<0.01).
