INFLUENCE OF THE DURATION OF KEEPING CALVES IN INDIVIDUAL HOUSES ON THEIR NATURAL RESISTANCE AND STATE OF HEALTH

The preservation of young animals and their resistance enhancement in the early postnatal period is a significant reserve for increasing the production of livestock products. The article presents the results of studies of the influence of the duration of 
keeping calves in individual houses on their natural resistance and state of health. It has been established that during the initial postnatal period, newborn calves retain the state of hyporesponsiveness, which gradually forms with age. Therefore, it is most appropriate to transfer calves from individual houses to group sections after stabilization of the formation of the body’s natural defenses, that is, not earlier than 30 days of age. With the duration of keeping young animals in individual houses for more than 30 days, there were fewer sick calves by 20-40% compared with counterparts who were transferred to group housing at the age of 20 days.
