Heteracidosis in pheasants

Abstract

Diseases of parasite etiology present a great part of the pheasant game pathology in both natural domiciles and artificial breeding. Based on the research conducted in our country and abroad, we have come to the conclusion that heteracidosis, along with coccidiosis, syngamosis, and ascaridiosis present one of the most significant parasite diseases in these birds. Heteracidosis in pheasants is caused by Heterakis isolonche and H. gallinarum. According to our findings H. isolonche is detect in 26,1 % of pheasants aged from 4 to 14 weeks, and 14,4 % of adult pheasants in organized maintenance conditions, and in 18,1 % of pheasants in nautural domiciles. Hetarkis gallinarum is found in 25,1 % of pheasants aged from 4 to 14 weeks and 4,3 % of adult pheasants in pheasant farms, and 15,3 % pheasants in natural domiciles. For these reasons, in this paper we present the carriers, pathological changes and clinical picture of the disease, as well as prevention and control methods.

Oboljenja parazitske etiologije zauzimaju značajan udeo u patologiji fazanske divljači u prirodnim staništima i veštačkom odgoju. Istraživanja sprovedena u svetu i kod nas pokazala su da heterakidoza, uz kokcidiozu, singamozu i askaridiozu predstavlja jednu od najznačajnijih parazitskih bolesti ovih ptica. Po našim nalazima Heterakis isolonche je ustanovljen u 26,13 posto fazana u uzrastu 4 do 14 nedelja i 14,40 posto fazana starijih od 14 nedelja odgajanih u veštačkom sistemu držanja, a kod 18,13 posto fazana u prirodnim staništima. Heterakis gallinarum je nađen kod 24,88 posto fazana u uzrastu od 4 do14 nedelja i 4,40 posto odraslih fazana u fazanerijama, a u 15,33 posto fazana iz prirodnih staništa. Iz ovih razloga ovde dajemo nalaz uzročnika, kliničku sliku i patološke promene, kao i mere preventive i suzbijanja heterakidoze.
