Özet
Araştırmada 20 adet hormonal ovo bursektomili ve 20 adet sağlıklı döllenmiş yumurta kullanıldı. Her gruptaki hayvanlardan yaşlarının 1., 5., 10. ve 15. haftalarında kan alındı. Araştırmada alyuvar, akyuvar ve trombosit sayıları ile hemoglobin ve hematokrit değer açısından gruplar arası farklılık yoktu. Çalışmanın 1. ve 5. haftalarında bursektomili grupta ienfosit yüzdesi kontrol grubununkinden önemli oranda düşük bulundu (P 0.05). Aynı örnekleme zamanlarında eozinofil yüzdesi bursektomili grupta (% 7.80, 6.60) kontrol grubununkinden (% 3.80, 4.20) önemli oranda yüksek bulunurken, relatif bir heterofili belirlendi. Diğer örnekleme zamanlarında ise bursektomili hayvanlarda lenfosit oranı düşük, eozinofil ve heterofil oranı kontrol grubundakinden yüksek seyretmesine rağmen istatistiksel önemin ortadan kalktığı dikkati çekti. Sonuç olarak hormonal ovo bursektorni; şirurjikal bursektomide olduğu gibi eozinofil sayısında artışa yol açarken eozinofil sayısının normal sınırlarda korunabilmesi için B lenfositlerin de gerekli olduğunu ortaya koymaktadır.
in the study, 20 hormonally bursectomized and 20 intact (control) eggs from native hibrit lines were used. Haernatoiogical examinations were performed in these birds at 1., 5., 10. and 15 th weeks of their ages. It was not obtained any differences between the groups in respect of erythrocyte, leucocyte and thrombocyte counts, ha-emoglobine and haemotocrit levels at any time period. Percentages of lymphocyte in the bursectomized group were significantly lower than in the control animals at 1 and 5 th weeks of their ages (P<0.05). In the same sampling times eosinophil percentages (7.80, 6.60 %, respectively) in the bursektomized group were observed to be significantly higher than those in the control group (3.80, 4.20 %, respectively). On the other hand in the bursectomized group he-terophil counts were determined relatively higher due to the decrease in lymphocyte counts as compared with the control group. The differences between the groups in respect of the percentages of lymphocyte, heterophil and eosinopnil were disappared after 5 th week although eosinophil and heterophil counts were still higher in the bursectomized group. In conclusion, hormonal in ovo bursectomy like surgical bursectomy resulted in higher eosinophil count and both B and T lymphocytes are necessary to maintain eosinophil count in normal range.
