The article presents the results of a study of the influence of adverse microclimate parameters on the morphological and immunological blood parameters of piglets in the neonatal period of development, and also evaluates the effectiveness of the use of the feed additive «Globigen Jump Start» to correct the identified violations. The study was conducted under production conditions with elevated air temperature and above-normal indoor ammonia concentration. It was established that deviations of microclimate parameters from reference values negatively affect the functional state of the piglets’ organism, which is manifested by changes in hematological and immunological blood parameters. The use of a feed additive containing egg immunoglobulins IgY, β-glucans and mannan-oligosaccharides increased the level of erythrocytes, hemoglobin and hematocrit (p<0.05–0.01), and also contributed to the normalization of the ratio of individual forms of blood leukocytes, in particular, an increase in the proportion of lymphocytes and a decrease in the number of neutrophils. The results obtained indicate a pronounced immunomodulatory and adaptogenic effect of the feed additive «Globigen Jump Start» and the feasibility of its use to increase the adaptive capacity and resistance of the piglet organism in the critical period of early postnatal development under the influence of environmental stress factors.
