Trichostrongylosis in cattle from South Marmara region of Turkey: assessment of various factors related to faecal egg counts

Bu çalışma Güney Marmara bölgesindeki sığırlarda hayvanların yaşı, ırkı, yönetim şekli ve çiftlik tipi ile dışkıdaki Trichostrongylidae yumurta sayısı arasındaki ilişkinin belirlenmesi amacıyla gerçekleştirilmiştir. 513 sığırdan rektal yolla alınan dışkılar modifiye McMaster yöntemi ile incelenerek gram dışkıdaki yumurta sayıları belirlenmiştir. Genel olarak, ortalama yumurta sayısı düşük düzeyde olmuş ve 81.4±6.8 olarak saptanmıştır. Dışkıdaki Trichostrongylidae yumurta sayısı yaşlı hayvanlarda gençlere göre daha yüksek bulunmakla birlikte yaş grupları arasında istatistiki olarak bir fark bulunmamıştır. Ortalama yumurta sayısı Boz ırkta Holstein ve Karacabey esmeri sığırlara göre daha yüksek olmakla birlikte ırklar arasında istatistiki olarak önemli bir fark belirlenememiştir. Yönetim şekli Trichostrongylidae yumurta sayıları üzerinde etkili bir faktör olup yarı ekstansif sistemdeki hayvanlarda entansif yönetim sistemindeki hayvanlara göre daha fazla yumurta saptanmıştır. Devlet işletmelerindeki hayvanların, küçük çaplı özel işletmelerdeki hayvanlardan daha az etkilendikleri belirlenmiştir.

Türkiye’de Güney Marmara bölgesindeki sığırlarda trichostrongylosis: dışkı yumurta sayısı ile ilişkili olarak değişik faktörlerin değerlendirilmesi

A cross-sectional study was carried out to determine faecal egg density in trichostrongyle infections in relation to animal age, animal breed, management system and farm type in cattle in South Marmara region of Turkey. Rectal faecal samples were collected from 513 cattle and coprological examination were conducted by a modified McMaster technique to determine faecal egg counts (FEC) per gram of faeces. Overall egg density was 81.4±6.8 EPG and it remained generally low. The mean faecal egg counts for adults was higher than those for the youngs. However, no statistically significant difference was found between the age groups for faecal egg counts. Although mean FEC were higher in Turkish Grey than in Holstein and Karacabey Bown, no statistically significant difference could be determined among the animal breeds. Management system was the factor that influenced number of trichostrongyle eggs and animals under semi-extensive system had more egg counts than those kept under intensive management system. Animals in the governmental farm have been found less affected with significant difference than their counterparts at small scale private farms.
