Kıl Yiyen Manda Yavrularında Oksidatif Stresin Değerlendirilmesi

Pika yem niteliğinde olmayan tahta parçaları, toprak, kemik ve kıl gibi maddelerin yenilmesi olarak tanımlanmaktadır. Kıl yeme hastalığı olan hayvanlar kendi vücutlarındaki veya diğer hayvanların vücutlarındaki kılları ısırıp kopararak deride alopecia ve yaralanmalara neden olabilirler. Bu araştırmada birbirlerinin kıllarını yiyen manda yavrularında total antiokidan durum (TAS), total oksidan durum (TOS) ve oksidatif stres indeksi (OSI) düzeylerinin araştırılması amaçlandı. Çalışmanın materyalini 110 başlık manda sürüsünde bulunan, 1-6 aylık yaşlarda, kıl yeme semptomu gösteren 22 manda yavrusu (Grup 1) ile kıl yeme semptomu olmayan ve herhangi bir hastalık belirtisi göstermeyen 6 manda yavrusu (Grup 2) olmak üzere toplam 28 hayvan oluşturdu. TAS, TOS ve OSI seviyelerini ölçmek için hayvanların vena jugularislerinden kan örnekleri alındı. Hasta hayvanların serum ortalama TOS ve OSI seviyelerinin kontrol grubuna göre önemli düzeyde yüksek olduğu tespit edildi. Sonuç olarak, kıl yeme semptomlu manda yavrularında oksidatif/antioksidatif dengenin oksidatif yöne kaydığı tespit edilmiştir.

Assessment of Oxidative Stress in Hair-Eating Buffalo Calves

Pica is defined as the appetite of the animals for non-feed substances, such as wood pieces, soil, bone, or hair. Animals with hair-eating disorders can bite and pluck hair from their bodies or other animals, causing alopecia and skin injuries. In the present study, it was aimed to investigate the total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) levels in buffalo calves that ate each other’s hair. The study included 28 calves from a buffalo herd of 110 animals, including 22 buffalo calves with hair-eating symptoms (Group 1) and 6 calves without any hair-eating symptoms or signs of any disease (Group 2), aged 1–6 months. Blood samples were collected from the animals’ jugular veins to measure the TAS, TOS and OSI levels. Serum mean TOS and OSI levels of Group 1 were significantly higher than Group 2. In conclusion, the oxidative/antioxidative balance in the buffalo calves with hair-eating symptoms shifted in the direction of oxidation.
