Abstract: The most common reason to assess the trace mineral status of ruminants is because performance is below expectation. Accordingly, the assessment is done to determine the presence or prevalence of nutrient deficiencies (or toxicities) within a population. Assessment also is done to evaluate efficacy of dietary supplementation or to compare available supplements. The aim of this study was to assessment of serum values of copper in cross-breed cows in east Azerbaijan province of Iran. In this study, 316 blood serums were obtained from cows growing in the pasture conditions were used as a material in 4 season of a year. The sera were extracted from the blood taken, and kept in the deep freeze in -20°C, until they are analyzed. The copper analyses in the serum were made with spectrophotometric method by Randox kit. The values found were evaluated by “t test”. According to the table 1 and 2, mean value of copper and ceruloplasmin was 0.21±0.85 ppm and 0.91±3.74 mg/dl in understudying animals respectively. So, based on ANOVA comparative test, there was significant difference in serum values of copper and ceruloplasmin in term of seasons. According to the tables 3 and 4, the serum value of copper in pregnant and non-pregnant cows was 0.21±0.84 and 0.21±0.87, respectively. Also, the serum value of ceruloplasmin in pregnant and non-pregnant cows was 0.87±3.68 and 0.94±3.81, respectively. So, based on ANOVA comparative test, there was no significant difference in serum values of copper and ceruloplasmin in term of pregnancy. It has been thought that this study will fulfill an important gap, because of not to be present the normal value of serum copper belonging to the sanjabian races. It is known that the excess and insufficiency of trace elements cause some disorders and decrease in production. So in order to search the effects of these substances, the normal values should be known.
