| Abstract | ||
| This study aimed to measure the biochemical markers including alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transferase (GGT), alkaline phosphatase (ALP), creatine kinase (CK), total proteins, albumin, globulin, albumin / globulin (A/G) ratio, glucose, blood urea nitrogen (BUN), and total bilirubin in sera of dairy cows from the period of February-2016 to March-2018. For this purpose, 78 dairy cows of >3 years old reared at some areas of Baghdad province were subjected to blood sampling from the jugular vein. Study values (mean ± standard error) of ALT, AST, GGT, A/G ratio and total bilirubin markers were found outside the normal ranges of international reference values. Conversely, ALP, CK, total protein, albumin, globulin, glucose and BUN were found within the normal ranges of international reference values. To investigate changes that occur during late stage of pregnancy, study animals were dividedinto two groups (non-pregnant lactating and pregnant dairy cows). Statistically, significant decrease (P<0.05) was encountered in values (M ± SE) of ALT, AST, and GGT enzymes; and significant increase (P<0.05) in ALP and CK values of pregnant compared to non-pregnant dairy cows. Data concerning the serum proteins, results also indicated a significant increase (P<0.05) in values of total protein, whereas there no significant differences (P>0.05) were showed in values of albumin, globulin and A/G ratio. Pregnant dairy cows were showed a significant increase (P<0.05) in values of BUN and total bilirubin; however, glucose appeared without significant differences (P>0.05). It has been concluded that the lactation and gestation periods have a great impact on activity of biochemical indices in blood of dairy cows; therefore, there is a need for constant periodic monitoring for the described indices in this study to maintenance on animal’s health status. | ||
