Use of integral leukocyte indices in assessing the eff ect of stress factors on goat homeostasis

The principle of a quantitative-qualitative approach, which reflects the activity of the organism while distinguishing its specific and non-specific adaptive responses, includes the requirement for quantitative assessment of specific changes in the body. To achieve the research objective, the resources of integral leukocyte indices (ILI) were used to assess the homeostasis of goats during castration, weaning from dams and transfer from pasture to stabling. After percutaneous castration, the index data vary significantly in a day, and in the month following the operation they slowly return to the level of the initial values. The surgical method of castration of goats acts as an unusual extreme stimulus, as it has a damaging effect on the body for a longer period of time. Changes in the blood of kids after weaning from dams were characterised by an increase in leukocytes by 36.84±2.71%, a change in the status of neutrophils, as they increased by 6.85±0.39%. The number of band immature neutrophils increased, but the presence of eosinophils decreased by 1.75±0.19 times, which is one of the indicators of the presence of a moderate stress factor. The transfer of goats to stabling leads to a sharp decrease in impulses from the skeletal muscles, which weakens the activating effect of the reticular formation of the brain on the cerebral cortex. The goat’s body is exposed to extreme stimuli, beyond the limits of everyday influences, and reacts specifically according to the nature of the activeagent. The most pronounced reaction is to open surgical castration, less so to percutaneous castration and then, in descending order: weaning of goats from dams and transfer from pasturing.
