Abstract |
The experiment was undertaken to study the effect of subclinical mastitis on the biochemical parameters of milk in crossbred (Sahiwal횞Jersey) cows. Subclincial mastitis was judged using California Mastitis Test and graded on a scale of 0 to 2. Twenty six milk samples of each grade were subjected to somatic cell count. Separated milk whey was analysed for total protein, immunoglobulin and trace mineral content. Results indicate linear increases in somatic cell count, total protein and immunoglobulin concentrations in milk with increase in grade of subclinical mastitis. However, copper, zinc, manganese and iron concentration in milk was not affected by grade of mastitis. |
