Growth, development and nonspecific resistance of calves under hypothermia

The article reflects the problem of implementation in the production of adaptive technology of growing calves because of the lack of methods farmakoprofilaktiki temperature stress, and adjustment adaptogenesis immunogenesis. According to the research biostimulants PS-2 and FS-4 activate the calves growth and development, hematopoiesis and metabolism, production of cellular and humoral factors of nonspecific resistance in conditions of hypothermia adaptive technology.
