Abstract
Распространение кишечных паразитических простейших у молодняка индеек на птицефабриках центральной России
Highlights
At the commercial poultry farms young growth turkeys of different age is infected by intestinal parasitic protozoa: Eimeria spp. on 5–20% in the case of low infection intensity, by Cryptosporidiumbaileyi on 10%
Изучение распространения кишечных паразитических простейших у молодняка индеек на птицефабриках Пензенской, Рязанской и Тульской областей показало наличие всех звеньев эпизоотической цепи: источник инвазии – зараженная птица; факторы передачи – контаминация объектов внешней среды инвазионными элементами и восприимчивый к инвазии выращиваемый в хозяйстве молодняк
Summary
The studies had been conducted at three specialized turkey-grower units of Central part of Russia in 2018-2019. Birds of different age were opened up, excrement aliquots and scrapes from the floor were studied for determination of the degree of infection of young growth turkeys by intestinal parasitic protozoa. In the case of cryptosporidiosis the excrements of ill young growth turkeys were studied according to direct smear Fullebourn's and Darling's method. In the case of eimeriosis excrements of different aged young growth turkeys were studied according to Darling's method. Carcases of different aged turkeys were studied to confirm histomonosis, cryptosporidiosis and eimeriosis according to above mentioned methods. In each of mentioned farms turkey at the age from 10 days had been examined once every 20 days by studying not less than 20 fresh excrements specimens and until full completion of technological cycle (150-155 days). The intensity of eimeriosis infection was measured by calculation the amount of oocysts per 1 g of poults’ excrements using McMaster's chamber under the microscope MBE
