Determination of Haptoglobin in Blood and Milk from Cows with Clinical and Subcilical Mastitis

The aim of our research was to determine level of acute phase proteins in cattle-haptoglobines in blood serum and milk and to investigate connection between haptoglobine and hematological parameters in blood and diagnostical value in determination of subclinical mastitis. We used 75 cows of symmental breed we divided in three groups. First group consisted of 30 cows with clinical mastitis, second consisted of 30 cows with subclinical mastitis and third group was control group of 15 healthy cows. All cows were clinically examined (generally and udder health control). We collected blood for hemogram and determination of haptoglobines in serum. Milk samples were used for bacteriological analysis, somatic cell count (SCC) and haptoglobine level. Comparison of SCC in milk had shown significant difference between all groups (p<0, 05). Middle values for hemogram in all groups were inside physiological range. Comparison of haptoglobine level in sera samples and milk has shown statistically significant difference between the groups (p<0, 05). Comparison of correlations of haptoglobine level in blood and serum and somatic cell count had shown real significant correlations. We concluded that determination of haptoglobine level in milk and sera samples could be used as significant diagnostic tool for subclinical mastiti sin symmental cows.
