Clinical and morphological features and diagnostics of avian eimeriosis

Research objective - studying of features of kliniko-morphological manifestation, diagnostics and treatment of an eymerioz at broilers of cross-country of Ross 308. Research was conducted on the poultry farm which is engaged in cultivation of broilers of cross-country of Ross 308 in Krasnoyarsk Krai. Eymerioz on poultry farm proceeded mainly subklinichesk, at some chickens noted a clinical current which was characterized by loss of appetite, a polidipsiya, fluidifying of a dung and deterioration of indicators of cultivation. The diagnosis on eymerioz was established by means of OPG monitoring, pathoanatomical opening and histologic researches. Invazirovaniye of a mucous membrane of a rectum of E. brunetti was followed by flabbiness of a wall of a foul place, an atrophy of a muscular layer, protrusion of a foul place, a prolapse and foul place rasklev. At an invasion of E.acervulina the duodenum was surprised, at E. maxima - all thin department of intestines, and at an invasion E. tenella - blind shoots of intestines. In thin department of intestines observed catarrhal enteritis and deformation of fibers of a mucous membrane. In thick department of intestines noted the catarrhal deskvamativny tiflokolit. Pleated intestines, a gleam of crypts and epiteliotsita of crypts found numerous merozoita. Application to chickens at the age of 19-20 days of 2,5 % of water solution of a toltrazuril in a dose of 1 ml / 1000 led l of water to reduction of quantity an ootsist on 350 thousand in 1 g of a dung that made about 50 thousand an ootsist in 1 g of a dung, was followed by improvement of kliniko-morphological indicators and increase of safety of chickens.
