Abstract
Способ оценки стрессоустойчивости коров, включающий воздействие на животных в процессе машинного доения стресс-фактора и изменение показателей молоковыведения, определение показателя стрессоустойчивости коров по среднему значению суммы оценочных показателей - отношение 1%-го молока, изменение интенсивности и полноты молоковыведения, отличающийся тем, что учитывается параметр проявления рефлекса молоковыведения - длительность второй фазы латентного периода по следующей формуле:где К - количество оценочных показателей;М, М, МДЖ, МДЖ, ИМВ, ИМВ- разовый удой (кг), массовая доля жира в молоке (%), интенсивность молоковыведения (кг/мин);ДВФЛП, ДВФЛП- длительность второй фазы латентного периода (с) в опытный и контрольный период;М, МДЖ- остаточное молоко (кг) и массовая доля жира (%) в нем в опытный период.A method for evaluating the stress tolerance of cows, including the impact of stress factor on animals during machine milking and changing the indicators of milk production, determining the stress resistance indicator of cows by the average value of the sum of the estimated indicators - the ratio of 1% milk, the change in the intensity and completeness of milk production, which is different the manifestation parameter of the lactation reflex is the duration of the second phase of the latent period according to the following formula: where K is the number of estimated indicators; M, M, MJ, MJ, I B, IMV - one-time milk yield (kg), mass fraction of fat in milk (%), intensity of milk excretion (kg / min); DVFLP, DVFLP - duration of the second phase of the latent period (s) in the experimental and control period; M, MJ - residual milk (kg) and mass fraction of fat (%) in it during the experimental period.
