ETIOLOGY AND DISTRIBUTION OF MASTITIS IN SHEEP

Abstract

The role of microbial factor in the etiology of sheep›s mastitis has been installed by of bacteriological analysis secretions udder from 56 healthy ewes, 76 ewes with the subclinical mastitis, and 48 ewes with the clinically expressed mastitis. During conducted investigations it was established, that mastitis has a broad distribution among ewes and reaches 19.0% in some sheep-breeding farm. Received data testify, that vertical zone their content doesn’t exert influence on distribution and development of mastitis in sheep, the revealed fluctuations are not important. Subclinical mastitis in ewes was found in 3-4 times more often, than clinically expressed. The main etiological factors of mastitis in ewes, by our mind, it is the lowering resistance of mammary glands and organism as a whole and the raising activity of pathogenic and conditionally pathogenic microflora. Has been established, that one and the same microorganism can be picked out from the milk of clinically healthy ewes and secret of sick by subclinical and clinically expressed mastitis. Therefore, microorganism in dependence of state common and local (mammary gland) resistance can cause any form of inflammation. Received data correspond to the results of other investigators.
