Clinical, hematological and serological study of sub-clinical mastitis in local cows in Basrah Province

الملخص EN

The present study was conducted to investigate the effect of subclinical mastitis on biochemical, hematological and minerals profile in local cows.

For this reason, 91 cows milk and blood samples were collected from sub-clinically infected cattle, were aged from 3-7 years in Basra/Iraq(between January 2015 to July 2015).

All the cows selected in this study were healthy without any clinical signs.

The result of present study revealed that there is change in physical properties of subclinical mastitis milk such as color, odor, turbidity, consistency and increase in the pH of milk, ranged from 7.07± 0.02 to 7.9 ± 0.02.

The study showed a significant increase of serum aspartate aminotransferase (AST) 217.4 ± 1.8 l/l, alanine aminotransferase (ALT) 136.0 ± 0.2 mmol/l, alkaline phosphatase (ALP) 120.5± 0.9 mmol/l) and lactate dehydrogenase (LDH) 816.

0 ± 3.4.

and increase the zinc level compared with control 1.26± 0.03.

Also there was decrease in monocyte count 3.52 ± 0.3 and 5.9 ± 0.1 from control 11.4 ± 0.3, the basophile count reveal there was slight increase in stage 1 of subclinical mastitis 2.99 ± and stage 2 retained to normal 1.2 ±0.05.

The present concluded that cows were causes change in physical properties of subclinical mastitis milk, changes in the biochemical, minerals and leukocyte count
