Bangladeş Feni İlçesinde Farklı Yaş Gruplarındaki Ticari Yumurtacı Tavuklarda Bulaşıcı Olan ve Bulaşıcı Olmayan Hastalıkların Prevalansı

Bangladeş Feni İlçesinde Farklı Yaş Gruplarındaki Ticari Yumurtacı Tavuklarda Bulaşıcı Olan ve Bulaşıcı Olmayan Hastalıkların PrevalansıBangladeşin Feni ilçesinde bulunan ticari yumurtacı işletmelerinde nekropsi ve diğer teşhis yöntemleriyle kanatlı hastalıklarının dağılımı araştırıldı. Bu amaçla 2009 yılının Haziran-Aralık ayları arasında ölmüş ve canlı olarak toplam 135 kanatlı örneği incelendi. Çalışmada sırasıyla salmonellosis (%22.79), kanatlı kolerası (%15.44), kolibasillozis (%10.29), nekrotik enteritis (%8.82), gumboro (%8.82), Newcastle (%8.08), koksidiyozis (%9.62), Lenfoid lökoz (%2.20), yumurta peritoniti (%5.15), kanibalismus (%2.94), E vitamini eksikliği (%1.47) ve sıcak çarpması (%2.20) vakaları tespit edildi. Araştırmada incelenen kanatlıların tüm yaş gruplarının çeşitli hastalıklara karşı duyarlı olmaları yanında salmonellozis, kolibasillozis, katlı kolerası, gumboro, Newcastle hastalığı ve nekrotik enteritisten kaynaklanan ölümlerin en savunmasız dönem olarak tespit edilen yumurtlama periyodunda olması dikkati çekti. Elde edilen bulgulara göre Bangladeş ticari yumurtacı işletmelerinin gelişimi açısından bulaşıcı hastalıklar önemli bir engel olarak görünmektedir. Bu sektörün ilerleyebilmesi için söz konusu hastalıkların önlenmesinin ve kontrolünün en acil eylem planı olması gerektiği kanaatine varıldı

Prevalence of Infectious and Non-Infectious Diseases in Different Age Groups of Commercial Layer Chicken in Feni District, Bangladesh

The pattern of occurrences of poultry diseases in commercial layer farms was studied based on post mortem and other examination of 135 cases either dead or live birds during the period of June to December, 2009 in the district of Feni. In the study highest number of cases of diseases found Salmonellosis (22.79%), Fowl cholera (15.44%), Colibacillosis (10.29%), Necrotic enteritis (08.82%), IBD (08.82%), ND (8.08%), Coccidiosis (9.62%), Lymphoid leucosis (2.20%), Egg Peritonitis (5.15%), Cannibalism (2.94%), Vitamin E deficiency (1.47%) and heat stroke (2.20%). It was very obvious from conducted study that all age groups of birds are susceptible to various diseases but the laying period is most vulnerable, and most mortality of chickens are caused by Salmonellosis, Colibacillosis, Fowl cholera, Infectious bursal disease, Newcastle disease and Necrotic enteritis. The findings indicated that infectious diseases appear to be a major constraint for development of commercial layer farms in Bangladesh which demands immediate attention for prevention and control for assuring the most progressive industry
