AMIDOSTOMOSIS OF GEESE IN FARM CONDITIONS USING EXTENSIVE GROWING TECHNOLOGIES

Abstract

The article provides data on the study of the spread of amidostomosis invasion of geese in farms using extensive cultivation technologies. Waterfowl helminthiasis is a common contagious disease. The economic losses from invasion increase with the associated course of helminthiasis. Amidostomosis is one of the topical nematodes of geese. The aim of our work was to study the spread of amidostomosis invasion of geese in the farms of the Chernihiv region, where extensive technologies of poultry rearing are used, to establish the extensiveness and intensity of invasion, the seasonal and age dynamics of the manifestation of amidostomosis invasion among the poultry. The studies to achieve the goal, coproovoscopic of goose feces were carried out and the species characteristics of invasive elements isolated from the droppings were determined. The studies, the spread of amidostomosis invasion of geese using extensive technologies of their breeding was established, a clear seasonal and age-related dynamics of its manifestation was noted. Amidostomosis invasion was recorded in farms where young poultry were in contact with parental poultry literally from the first weeks of life. In these farms, from poultry droppings, eggs with amidostome began to be found from 1.5 months. age, with an extensiveness of invasion of 0.2-2.5%. In the following age groups of geese, the extent of invasion was: 2.5-3.5 months. - 10.5-22.3%; 4-5 months - 26.1-50.4%; 6-7 months - 32.0-82.1%; 8-9 months - 23-49.2%; 10-12 months - 15.0-21.6%. The peak of amidostomous invasion was recorded in the fall, intensity of amidostomosis invasion of 3.25 ± 0.12 specimens / drop of flotation fluid. The intensity of amidostomosis invasion gradually decreased in winter and reached its minimum values in March - 0.74 ± 0.16 specimens / drop of flotation fluid. The livestock of geese in farms where free-range keeping of young animals was not practiced in the spring-autumn period was favorable for amidostomosis and other nematodes of the alimentary canal. We recommend using anthelmintic drugs containing several active ingredients to effectively overcome amidostomosis invasion in geese, in dysfunctional farms.
