Особливості клінічного прояву післяродових маститів у високопродуктивних корів в умовах приватного підприємства «Агро-Союз» Синельниківського району Дніпропетровської області

Abstract

Встановлено, що основними чинниками маститу у корів в післяродовому періоді є набряки і рани вим’я, грубе порушення режиму машинного доїння, наявність протягів та низька температура в приміщеннях. Найчастіше мастити виникали у корів з 4-ю та 6-ю лактацією у післяродовому періоді, і в більшості випадків проявлялись у серозній та катаральній, менше у фібринозній й катарально-гнійній формах запалення. Установлено, что основными причинами мастита у коров в послеродовом периоде есть набряки и раны вымени, грубое нарушение режима машинного доения, наличие сквозняков и низкая температура в помещениях. Чаще маститы возникали у коров с 4-й и 6-й лактацией в послеродовом периоде и чаще проявлялись в серозной и катаральной, редко в фибринозной и катарально-гнойной формах воспаления. The results of our studies established that the main factors of mastitis in cows in postnatal period is swelling and wounds of the udder, blatant violations of the milking technologies (not milking fully), the presents of drafts and low temperature in the keeping areas. Mastitis in cows often arose with 4th and 6th lactation in postnatal period, and in most cases manifested in a serous - (8.4%) and catarrhal (5.6%) less fibrinous - (2.1% ) and catarrhal-purulent (1.9%) forms of inflammation. Serous mastitis accompanied by increasing of affected parts and redness of the skin of the udder; in catarrhal mastitis in teat and on the lower third of the affected part were detected fluctuating limited areas, distinguished by the augmentation of affected quarters and slight pain. Catarrhal mastitis manifested in slight deterioration of general condition, redness of the affected quarter, affected part is painful. In gland tissues were determined fluctuating limited areas and cords. The secretion of milk was reduced, milk was watery, in some cows at the beginning of the milking milk was with impurities of casein flakes and clots. Catarrhal-purulent mastitis are accompanied by a general despondency of animals, increase the temperature to 41⁰C, an increase in the volume of affected particles, their hyperemia and induration of the tissue. Hemorrhagic mastitis had an acute course with fever 40-41⁰C and with accelerated pulse and breathing; affected parts thus been increased in volume, painful, hot, dense with red spots on the skin, teats swollen, dark red color. Fibrinous mastitis accompanied by depression, stress, pain, redness of the affected particles of the udder and enlarged lymph nodes. In the analysis of the udder secretion from the animals with clinical forms of mastitis established that in the early stages of serous mastitis milk had no visible change, and subsequently became watery with flakes of casein. In cows with catarrhal mastitis from the affected parts of the udder excreted secret had a casein clots. From cows with catarrhal-purulent mastitis were milking few drops of serum with impurities of casein clots, solid yellow crumbs and flakes. Often the secret revealed admixture of pus. In udder with fibrinous mastitis secret revealed a large number of grains of fibrin.
