Abstract:
The paper goal is providing fact finding data arguing the need to conduct selection of deer as per their type of reactivity
to stress. The latter was determined through the use of the modified adrenaline test initially elaborated by Ahmadiev
G.M.(1990) that allows deer livestock selective breeding of the animals with a high resistance to infestation with
diverse parasites, an increased potencial of treatment efficacy, prophylactics of parasitoses and applying the
antiparasitic treatment depending on their type of stress reactivity. The innovative procedure of animals selection
depending on their stress reactivity was elaborated and applied into the practice that correspondingly allowed the
selection and setting the deer population with high resistance to the parasitic infestation and with increased efficiency of
anti-parasitic therapy. As related to establishement of the efficacy of the antitapasitic remedies the recommemdations
included the necessity to consider not only the specifics and level of infestation of deers, but also their type of reactivity
to stress, and those stres-reactive animals require repetative anti-parasitic treatment to allow the desired anti-parasitic
effect. The paper includes data on the impact of the mono- and poliparasitic invasions as well as the effect of
antiparasitic therapy on some morphological and functional indices in deers with different types of reactivity to stress.
