One of the main factors hindering the growth of milk productivity and deteriorating the sanitary quality of farm produced milk is mastitis. Mastitis can occur during lactation, drying off and interlactation periods but more often during the lactation period, when the mammary gland is under enormous exertion. The aim of the research was to study the features of mastitis manifestation in dairy cows under the Amur region conditions. Samplings were carried out in September-October. Milk was analysed using the Masttest rapid diagnosticum. Studies showed that mastitis was not diagnosed in 39.1 % of cows, in 20.3 % of cows it was dubious (lesion of the posterior udder lobes). In 40.6 % of cows the mastitis was diagnosed in the form of lesion of the posterior udder lobes, whereas the anterior udder lobes showed dubious result. The mastitis positive diagnosis in cows in at least one lobe of the udder may indirectly indicate the presence of subclinical mastitis in the remaining udder lobes or the transformation of the subclinical form of mastitis into clinical one under the influence of unfavourable external factors and in the absence of therapy. |
