| Popis: | Milk and blood serum from clinically mastitis infected, subclinically mastitis infected and healthy Friesian cows (15 samples from each of 3 groups) were evaluated for macrominerals (sodium, potassium, calcium, magnesium and phosphorus). The milk from cows infected with subclinical mastitis revealed a significant decrease in potassium (P 0.001) and a significant increase in sodium and phosphorus content (P 0.01). Similarly, the milk from cows with the clinical form of the disease showed a significant increase in sodium (P 0.001) and a significant decrease in potassium, magnesium (P 0.001) and calcium (P 0.01). Comparison of healthy cow's milk with that from cows with subclinical mastitis revealed a highly significant increase in sodium (P 0.001). Comparison of healthy cow's milk with that of clinically mastitic milk showed a highly significant decrease in levels of calcium, magnesium (P 0.001) and potassium (P 0.01). However, sodium increased highly significantly (P 0.001). Comparison of macro-minerals in milk from cows with subclinical and clinical mastitis revealed a significant decrease in potassium contents (P 0.05) compared with that of healthy cows. Potassium levels were found to decrease significantly (P 0.05) in subclinically infected cow's blood serum. However, calcium and phosphorus showed a significant decrease (P 0.01) in blood serum samples from the clinically infected cows. |
