The activity of the immunocompetent cells in correlation of the immune status at the newborn calves in dependence of age

Abstract

The investigations reflected in this scientific research were performed with the main purpose to study the dynamics of the immunocompetent cells indices T and B at the newborn calves at the age of 5; 10; 20 and 30 days. There was determined in dynamics the number of the leukocyte, lymphocyte indices of the T and B cells. These data indicate the principal effector role in the activity of the immune system, as a efector of the immune reactions mediated cellular and humoral, capable of ynthesizing some limfokine etc. Simultaneously increasing the concentration of the B lymphocytes justify early onset of humoral specific resistance of the immune status and receiving via colostrum antibodies in the neonatal period, as a result of the colostral immunity installation. The study results demonstrated that the newborn calves are born with an cell well formed lymphocytic immune system, represented by the organism’s immune homeostasis correction.
