A science was conducted to determine the enterosorbent influence on morphological and biochemical parameters of the breeding boars blood, which took place within the State Enterprise on Breeding and Pig Crossbreeding ”Moldsuinhibrid” since March 18. 2014 till August 06.2014.   To conduct the science clinically healthy breeding boars Yorkshire, Landrace, Duroc and Pietrain were chosen and formed into groups by the analogy method (n = 3). In the first period of study, the research showed that the boars had approximately equal proportion of albumin and globulin and vary from 0,78  to 0,97. In the second and third periods of science the protein globulin fraction of the animals was increased (p>0,05).
