Results of research of establish the species composition of pathogens in gastrofileza Fedorovskoye area LLP "Nuray" are shown in Table 1.

Species composition of gastrointestinal gadfly in Fedorovskoye area LLP "Nuray" for 3 years (2011-2013).

№	Types of gasterofilyus	Number of copies	II, %
1	G. intestinalis	1800	59
2	G.haemorrhoidalis	1037	23,4
3	G.veterinus	849	17,6
	Total	3686	100

With the help of results of parasitological analysis of autopsies in three years (gastrofilez was detected in 24 of the total number of horses slaughtered horses) horses found that fauna gastrointestinal gadfly horses Fedorovsk district is represented by three species. As follows from the data in Table 1, the dominant species is G. intestinalis (large gastric gadfly) - 59%, subdominiruyuschim - (usokley) G.haemorrhoidalis - 23,4%, G.veterinus (dvenadtsatiperstnik) - 17.6%.
