Работа  посвящена изучению особенностей формирования иммунитета у новорожденных телят. Объектом исследований служили коровы бестужевской, черно-пестрой, голштинской, айрширской пород и их потомство, разводимые в природно-климатической зоне Среднего Поволжья и Южного Урала. Установлено, что за последний месяц перед отелом в сыворотке крови коров происходит снижение содержания иммуноглобулинов, у бестужевской породы на 19,3%, черно-пестрой — на 15,8%, голштинской — на 13,4%, айрширской — на 15,0%. Это обусловлено тем, что иммуноглобулины интенсивно перемещаются в клетки секреторного эпителия альвеолярной ткани вымени. В молозиве первого удоя содержится от 57,86 г/л (голштинская порода) до 106,78 г/л (бестужевская порода) иммуноглобулинов. В молозиве второго удоя содержание иммуноглобулинов снижается у бестужевской породы на 18,9%, черно-пестрой — на 25,1%, голштинской — на 29,3%, айрширской — на 21,7%, а при четвертом доении, соответственно, на 45,4; 51,6; 52,4; 49,2%. Через 6 ч после первого выпаивания молозивом, содержание иммуноглобулинов в сыворотке крови телят всех пород, за исключением голштинской, было выше 10 мг/мл, что считается физиологической нормой. Исследования показали, что в каждой породе есть телята, не воспринимающие иммуноглобулины из молозива матери, доля которых составляет, соответственно 20; 16; 30; 10%. Наиболее опасными для здоровья теленка являются первые 5 дней жизни. В этот период в бестужевской породе заболело 6% телят, черно-пестрой — 24, голштинской — 42, айрширской — 14%. Всего за первый месяц жизни заболеваемость телят в группах составила, соответственно, 16; 48; 76; 26%.The article presents the study of peculiarities of immune development in newborn calves. The objects of interest were Bestuzhev, Black-and-White, Holstein and Ayrshire cows and their progeny raised in the environmental and climatic zone of Middle Volga and Southern Ural. The study has shown that during the last month prior to calving there was a decrease of immunoglobulin content in the cows’ blood serum: in Bestuzhev cows by 19.3%, in Black-and-White cows by 15.8%, in Holstein cows by 13.4% and in Ayrshire cows by 15.0%. This is due to the fact that immunoglobulins massively migrate to secretory epithelium cells of the udder alveolar tissue. Immunoglobulin concentration in the first milking colostrum was from 57.86 g/l (Holstein cows) up to 106.78 g/l (Bestuzhev cows). In the second milking colostrum the content of immunoglobulins was decreased by 18.9% in Bestuzhev cows, by 25.1% in Black-and-White cows, by 29.3% in Holstein cows and by 21.7% in Ayrshire cows, in the forth milking colostrum the decrease was respectively by 45.4; 51.6; 52.4 and 49.2%. 6 hours after the first colostrum feeding immunoglobulin content in blood serum of calves of all breeds except for Holstein one exceeded 10 mg/ml, what was within the physiological norm. The study has shown that there were calves in every breed who did not accept immunoglobulins from the mother’s colostrum, their percentage was respectively 20; 16; 30 and 10%. The first five days of life were the most dangerous for the health of calves. During the period 6% Bestuzhev calves, 24% Black-and-White calves, 42 Holstein calves and 14% Ayrshire calves fell ill. During the fist month of life the morbidity rate of calves was respectively 16; 48; 76 and 26%.

The Impact

Dairy calves are unable to mount an effective immune response during their first weeks of life, which contributes to increased disease susceptibility during this period. Oxidative stress (OS) diminishes the immune cell capabilities of humans and adult cows, and dairy calves also experience OS during their first month of life. However, the impact that OS may have on neonatal calf immunity remains unexplored. Thus, we aimed to evaluate the impact of OS on newborn calf lymphocyte functions. For this, we conducted two experiments. First, we assessed the association of OS status throughout the first month of age and the circulating concentrations of the cytokines interferon-gamma (IFN-γ) and interleukin (IL) 4, as well as the expression of cytokine-encoding genes IFNG, IL2, IL4, and IL10 in peripheral mononuclear blood cells (PBMCs) of 12 calves. Subsequently, we isolated PBMCs from another 6 neonatal calves to investigate in vitro the effect of OS on immune responses in terms of activation of lymphocytes, cytokine expression, and antibody production following stimulation with phorbol 12-myristate 13-acetate or bovine herpesvirus-1. The results were compared statistically through mixed models. Calves exposed to high OS status in their first month of age showed higher concentrations of IL-4 and expression of IL4 and IL10 and lower concentrations of IFN-γ and expression of IFNG and IL2 than calves exposed to lower OS. In vitro, OS reduced lymphocyte activation, production of antibodies, and protein and gene expression of key cytokines. Collectively, our results demonstrate that OS can compromise some immune responses of newborn calves. Hence, further studies are needed to explore the mechanisms of how OS affects the different lymphocyte subsets and the potential of ameliorating OS in newborn calves as a strategy to augment the functional capacity of calf immune cells, as well as enhance calves’ resistance to infections.
