Japon bıldırcınlarında (Coturnix coturnix japonica) hipertiroidizm ve hipotiroidizmin canlı ağırlık ile karkas değerleri üzerine etkileri

Sunulan araştırmada deneysel hipertiroidizm ve hipotiroidizmin canlı ağırlık ile karkas değer-leri üzerine etkileri araştırıldı.Materyal olarak 4 haftalık 45 adet dişi Japon bıldırcını kullanıldı. Hayvanlar herbiri 15 bıldırcından oluşan kontrol, hipertiroidi ve hipotiroidi olmak üzere 3 gruba ayrıldı.Yemlerine 5 hafta süreyle 0.4 mg/100 g levatiroksin-sodyum katılan bıldırcınlarda hipertiroidi, %0.2 propiltiyourasil (PTU) katılan hayvanlarda ise hipotiroidizm oluşturuldu. Kontrol grubuna ise 5 hafta süreyle katkısız ticari bıldırcın yemi verildi.Deneme sonrasında T4 düzeyi hipertiroidi grubunda istatistiksel önemde artarken (P

The effects of hyperthyroidism and hypothyroidism on body weight and carcass values in japanese quails (Coturnix coturnix japonica)

In this study, the effects of experimentally induced hyperthyroidism and hypothyroidism on body weight and carcass in Japanese quails were investigated.A total of 45 4-week old female Japanese quails were used. The quails were divided into 3 groups as control, hyperthyroid and hypothyroid group, with 15 quails in each.0.2% propylthiouracil (PTU) was added into the diet of hypothyroid group, and 0.4 mg /100 g levat-rocsyn- sodium was added into the diet of the hyperthyroid for 5 weeks. The birds in the control group were fed with unsupplemented commercial diet for 5 weeks.The mean plasma T4 level increased statistically (P
