Estimation peculiarities of immunobiological responsiveness of cattle and pig organism

As a result of our investigations it was established, that cattle had an authentically low concentration of a whole protein and its fractions, mucin, T-lymphocytes, alkaline phosphatase activity, myelopiroxidase, lysosomal-cationic proteins and on the contrary authentically high characteristics of an acid phosphatase, B-lymphocytes, bactericidal and lysozymic activity of blood serum with regard to clinically healthy pigs. An oxygendepending nonenzyme system (myelopiroxidase) and an oxygenindepending nonenzyme system (lysosomal- cationic proteins) of pigs take more active part in phagocytosis process than those of cattle. A given circumstance indicated the different nature of blood serum defenses depending on animal species.
