Dynamics of some immunobiological indices in cattle dependent on age

Abstract

The immune activity of the animal organism is the activity of some immunobiological indices, which constitute the essence of immune investigations regarding the behavior of cellular immunity in animals. Immunity is the body`s ability to defend itself against pathogens - viruses, bacteria, parasites and toxins. The immune system is a complex system of cells and molecules (antibodies) whose role is to provide protection against aggressors. The objective of this research is to present an analysis and assessment of some immunobiological indices in cattle depending on age. The research results offer the possibility to interpret the role of immune cells in the installation of the immune response in the animal body.
