Abstract

Keçilerde koksidiyal ookist OPG ve parazit yumurtası EPG yükü ırk, cinsiyet, mevsim, yetiştirme sistemi gibi etmenlere göre değişebilmektedir. Bu çalışmada Gökçeada, Malta ve Türk Saanen keçi genotiplerinde üç yıl süreyle OPG, EPG ve kan hematokrit değeri PCV takip edilmiştir. Malta genotipi iç parazit yumurtası bakımından diğer keçi genotiplerinden önemli derecede düşük düzeyde yüke sahip olmuştur P≤0.05 . Gökçeada keçilerinin ilk gözlemde Eimeria ve mide bağırsak kıl kurtları bakımından prevalansı % 100 olurken, Malta genotipinde Eimeria’da % 98, mide1. IntroductionParasite diseases are the leading cause of the losses in sheep husbandry. It was reported that 60% of the losses in sheep husbandry in USA are due to parasite diseases Charon 2004 . Thus, research on the parasites has been steadily increasing lately. The most common method of controlling parasites is the use of drugs. However, factors such as parasite resistance and risk of residues make these control methods questionable. Therefore, in the recent years, different approaches have been adopted to determine resistance or tolerance to parasites among breeds or individuals. There are reports of genetic variation of resistance on gastrointestinal parasites between and within goat breeds Chhabra & Pandey 1991; Pralomkarn et al 1997; Baker et al 1998; Baker et al 2001 . The studies in the last twenty years have shown that, by selection, it may be possible to get resistant or tolerant animals to parasite diseases Bishop & Stear 1997; Gauly & Erhardt 2002; Cardellino et al 2002 .Coccidiosis, caused by the protozoa of Eimeridae family, is a contagious disease that may OPG and EPG, and packed cell volume PCV .bağırsak kıl kurtları içinse % 78’lik bir prevalans tespit edilmiştir.

A Comparison of Natural Eimeria spp. and Gastrointestinal Nematode Infections of Goat Breeds

Abstract

The number of Eimeria oocysts per gram faeces OPG and number of gastrointestinal nematod GIN eggs per gram faeces EPG depend on some factors such as gender, season and production systems. In order to determine the Eimeria infection and some gastrointestinal nematode burdens in Maltese, Gökçeada and Turkish Saanen goats, OPG, EPG and packed cell volume PCV were investigated. Maltese breed tended to have lower parasite burden than other goat breeds P≤0.05 . In the first observation, the prevalence of Eimeria and nematodes was 100% in Gökçeada breed, while the prevalence of Eimeria and the prevalence of GIN infection were 98% and 78%, respectively, in Maltese. It was determined that OPG and EPG burdens were significantly affected by the age of goats and the sampling date P≤0.0193 . It was seen that OPG burden decreased as the goats get older P= 0.0157 , while EPG value varied by the age of a goat in an unsteady manner P
