Halka Boyunlu Sülünlerde (Phasianus colchicus) Nakil Kaynaklı Stresin Önlenmesinde C Vitamininin Etkinliğinin Araştırılması

Amaç: Bu çalışmada, halka boyunlu sülünlerde nakil kaynaklı stresin önlenmesi veya azaltılmasında C vitamininin etkinliği araştırıldı. Materyal ve Metot: Çalışmada 10’ar sülünden oluşan bir kontrol ve iki deneme grubu oluşturuldu. Deneme gruplarına canlı ağırlıkları bazında 200 (AA1) ve 400 (AA2) mg/kg dozda C vitamini günlük olarak içme suları içerisinde verildi. Bir haftalık uygulama sonrasında sülünler iki saat boyunca taşındı ve plazma kortikosteron (CS) düzeyleri ile heterofil/lenfosit oranları (HLR) taşıma öncesi ve sonrası olmak üzere belirlendi. Bulgular: Nakil öncesi ve sonrası elde edilen değerler karşılaştırtıldığında, kontrol grubunda her iki parametre için de nakil sonrası anlamlı artış belirlenirken, AA1 ve AA2 gruplarında sadece plazma CS düzeyinde anlamlı artış saptandı. Her üç grup için de bakılan parametreler bağlamında nakil öncesi tüm değerler benzerdi. Nakil sonrası ise plazma CS düzeyleri ve HLR deney gruplarında benzerdi, fakat deney gruplarına ait değerler kontrol grubundan anlamlı şekilde düşüktü. Sonuç: Sülünlere nakil öncesi 1 hafta süreyle oral C vitamini verilmesi, nakil kaynaklı stres yanıtında azalma sağlamaktadır.

Investigation of theEffect of Vitamin C In The Prevention of Transport-Induced Stress in Ring-Necked Pheasant (Phasianus colchicus)

Objective: In this study, the efficiency of vitamin C on the prevention or reduction of transport induced stress in ring-necked pheasants was investigated. Material and Method: Two experimental and a control group were formed in the study. Vitamin C was given to the experimental groups in the drinking water for one week at the levels of 200 (AA1) and 400 (AA2) mg/kg BW daily. After one week, the pheasants were transported and the plasma corticosterone levels and heterophil/lymphocyte ratio were determined before and after transport. Results: When the values obtained before and after transplantation were compared, a significant increase was found after transplantation for both parameters in the control group, while a significant increase was found only in plasma CS levels in the AA1 and AA2 groups. All parameters before and after transport were similar in all three groups. After transport, level of plasma corticosterone and heterophil/lymphocyte ratio were similar in the experimental groups, but these parameters were lower than the control group. Conclusion: Administration of oral vitamin C for one week before transportation decreases transport induced stress response.
