Вплив привязного і непривязного утримання на захворюванність нетелей і первісток на мастит
Abstract
Наведено результати досліджень щодо впливу технології утримання нетелей – прив’язної і безприв’язної – на їх захворюваність на мастит на 7–9-му місяці тільності й відразу після отелення. Нетелі на 41 % і чверті на 38 % менше хворіли на запалення молочної залози за безпри’вязної технології. Аналогічною була тенденція у разі захворювання на мастит первісток. На 24,9 % у тварин і 7,3 % чвертей це захворювання діагностували рідше за безприв’язної технології утримання. Велика рогата худоба, технологія утримання (прив’язна, безприв’язна), нетелі, первістки, мастит.
