Abstract

The great problem of rabbits breeding today is coccidiosis. An agent of the disease spreads not only through ill animals and is preserved well in the external environment. Oocysts of coccidia live in cells for a long time, so even temporal vacation of an accommodation between placing of rabbits doesn’t prevent infection. It was experimentally proved, that there is a very limited spectrum of means that are coccidiostatics. For preventing and controlling rabbits’ eimeriosis, coccidiostatic means were tested. It is very difficult to annihilate coccidia in vivo and in vitro because of peculiarities of their construction. The aim of the first experiment was to determine the influence of an acidifier Cronocyde L and its components on oocysts of coccidia that allows to determine an optimal composition and concentration of the preparation. At conducting the research, there was used the flotation method of Fulleborn and McMaster one for calculating oocysts. The aim of the second experiment was to determine the influence of the acidifier Cronocyde L standard and Cronocyde L concentrate (1 ml/1l of water) on the intensity of the living mass increment in rabbits. For that there were used clinical, hematological, zootechnical and microscopic methods. Optimal results in the experiment were obtained at using Cronocyde L concentrate and Cronocyde L standard in concentration 0,1 %: maximal growth and health status of rabbits, biochemical indices of blood serum were within the physiological norm. It testifies to the effectiveness of this preparation at eimeriosis of rabbits and to harmlessness for them. The studies, realized under laboratory conditions, prove the effectiveness of the offered means.

Highlights

Coccidioses are spread in all countries of the world and cause essential losses to animal husbandry
The research results demonstrated that oocysts of coccidia were influenced by all presented preparations: Cronocyde L standard and Cronocyde L concentrate and acids
The obtained results of annihilating coccidia at pH of the preparation within 3.5–4.5 in vitro under laboratory conditions gives a possibility to use this composition as a coccidiostatic for rabbits

Summary

Introduction

Coccidioses are spread in all countries of the world and cause essential losses to animal husbandry. It occurs in animals not depending on their age or race. Ill animals excrete oocysts that are a source of invasion with excrements, and transmission factors are forages, water, bedding, equipment of animal husbandry accommodations, servicing subjects and so on, polluted by them. Inflammation by coccidia is realized by the alimentary way as a result of swallowing oocysts with water or forage [1, 2]. The high vitality of cysts and oocysts of potozoa, eggs and larva of helminthes, ticks and insects and their ability to survive after the contact with chemical substances in concentrations and expositions, destructive for pathogenic microorganisms, is a serious problem in the fight against invasive diseases of animals and humans. The stableness degree of oocysts of eimeria of pigs, ruminants, rabbits and poultry relates to the group of high-stable agents of parasitosis [3, 4]
