Features of behavior, dynamics of live weight and indices of the blood of import heifers in the course of their adaptation in the Amur region

The features of import heifers of the Australian cattle Hereford breeds’ adaptation to conditions of the Amur region and the influence on easing of adaptable stress of experimental fodder additives were investigated. Import heifers’ reaction on the introduction of two experimental fodder additives into a diet are studied: aluminous vitamin-mineral and enzymatic probiotic, developed by the authors, as means of adaptable qualities of animal strengthening. The use of experimental fodder additives was positively reflected in behavior, daily average growth of live weight, indices of the blood of animals and process of their adaptation to local conditions.
