Show Mastitis Spreading According to recognized authorities, authori-ties, 52 per cent of all the cows in Germany have mastitis, about 40 per cent of Great Britain's cows are infected, and 48 per cent, or nearly one out of every two cows in America, Amer-ica, are infected with this disease. Dairymen no longer consider mastitis, masti-tis, or garget, a necessary evil, but are learning to diagnose the disease and are taking every precaution to prevent its spread. The organism which causes garget destroys the milk-producing tissue of the udder and lowers the average butterfat and milk production about 22 per cent. Considering that every other cow in the average dairy herd has garget, that 22 per cent loss in production pro-duction from each infected cow means an 11 per cent loss on the herd as a whole. |
