The effect of feed additives Permamik and Calcefit-5 on the clinical and physiological parameters of boars was studied. An assessment of the dynamics of growth, hematological and andrological parameters of experimental animals is given, depending on the simulated conditions. It was found that the used feed additives do not have a negative effect on growth processes and hematological parameters, while contributing to the improvement of sperm parameters during puberty of animals.
