Features of natural resistance and physiological-biochemical status in calves with diarrhea signs

The aim of the study is to establish correlation links between the indices of natural resistance, morpho-biochemical and coagulation blood composition in calves.

Black-and-white calves up to 30 days old have been divided into 2 groups: healthy calves and calves with dyspepsia. Hematological and statistical methods of investigation are used in the work.

The influence of cortisol on some immunological parameters of carps

This paper presents an assessment of changes in some indicators of the immune system in the control and experimental group of carp under the influence of endogenous cortisol. It was found that when the level of cortisol increases the activity of cellular immunity in fish created by leukocytes increases as well. Other indicators of the immunological status decrease with the increase of this hormone.
