Özet
Bu çalışmada gelişme geriliği problemleri olan düvelerde Zn, Cu ve tiroid hormon konsantrasyonlarının rolünü araştırmak amaçlandı. Çalışmada Yüzüncü Yıl Üniversitesi Veteriner Fakültesi İç Hastalıkları kiliniğine getirilen 6-12 aylık yaşlarda 35-50 kg canlı ağırlığında 11 adet (Test Grubu) ve normal canlı ağırlığında (80-100 kg) 6 adet (Kontrol Grubu) Doğu Anadolu Kırmızısı düve materyal olarak kullanıldı. Klinik olarak enfeksiyon ve paraziter enfestasyon teşhis edilemedi. Bu nedenle, büyüme çağındaki düvelerde gelişme geriliğine neden olduğu bilinen iz element ve troid hormon durumları araştırıldı. Kontrol grubundan elde edilen değerlerle karşılaştırıldığında test grubunda Zn, Cu, T3, FT3, T4 ve FT4 değerlerinin daha düşük olmasına rağmen, sadece Zn (p<0.05), T4 ve FT4 (p<0.01) değerlerindeki farklılıklar istatistiksel olarak önemli bulundu. Bu nedenle, özellikle Zn ve Cu içeriğinden yetersiz ve dengesiz beslenmenin, test grubunda absorbsiyon bozukluklarına yol açarak growth hormonunun stimülatörü olan tiroid hormon konsantrasyonları ve gıda değerlendirilmesindeki azalmaya bağlı olarak gelişme geriliğine neden olduğu sonucuna varıldı.
In the present study the role of Zn, Cu and thyroid hormone concentrations in the heifers having retardation of the growth problem were aimed to investigate. In this study, 11 Eastern Anatolian Red heifers weighing 35-50 kg body weight (test group) and 6 Eastern Anatolian Red heifers in normal body weight (80-100 kg) (control group) aged between 6-12 months brought to the University of Yuzuncu Yil, Faculty of Veterinary Medicine, Department of Internal Diseases were used as materials. Clinically, infection and parasiter infestation could not be diagnosed. Therefore, trace elements and thyroid hormone status that are known to cause retardation of growth in the growing heifers were investigated. Although Zn, Cu, T3, FT3, T4 and FT4 values were lower in the test group compared to the values obtained from control group, the differences were statistically important only in Zn (p<0.05), T4 and FT4 (p<0.01) values. Therefore, it was concluded that inadequate and unbalanced feeding, specifically in Zn and Cu content, caused retardation of growth in test group via causing absorption disorders, reduction in the feed efficiency and thyroid hormone concentrations, which are the stimulator of growth hormone.
