Preventing shipping stress in imported heifers with the use of immunocorrection

Abstract

Dependence of selective mobilization of sympathoadrenal, serotonin-and histaminergic body systems, morphological and biochemical profiles of blood, activity of transamination enzymes and factors of nonspecific resistivity on the background of using biopreparations aimed at preventing shipping stress and commercialization of the bioresource potential of imported heifers on the pressing environmental and technological stress factors has been disclosed. On the background of using biological products, improvement of the reproductive qualities of heifers was noted, the age of fruitful insemination, age at first calving, insemination index, and service period decreased, and fertility during first heat increased.
