Аннотация
В исследовании приведены результаты по определению типа стрессоустойчивости молочных коров по уровню кортизола в крови в состоянии «условного покоя». Также изучено влияние перегруппировки животных на концентрацию гормона кортизола в крови. Выявлено, что перегруппировка животных способствует увеличению концентрации кортизола в крови. Установлено, что высокий уровень кортизола в крови молочных пород крупного рогатого скота влияет на снижение уровня молочной продуктивности
