Abstract

The purpose of the present study was to determine the effects of dietary green tea powder on growth performance and some blood metabolites of broiler chicks. Day-old male broiler chicks (Ross 308) were divided 4 treatments groups with similar live weight mean (42.49±0.32 g/bird), containing 20 birds each. The birds were fed a basal diet (control group) or a 2, 4, and 8 g/kg green tea powder-supplemented diet for 5 weeks. Feed and water are given ad libitum. Data were collected on growth performance, carcass characteristics, and blood metabolites [total antioxidant status (TAS), total oxidant status (TOS), alanine aminotransferase (ALT), and aspartate aminotransferase (AST)] in the experiment. The results showed that performance and carcass slaughter characteristics were not affected by dietary supplementation with green tea powder compared with the control group. Serum oxidative stress index and ALT activities were increased by green tea powder supplementation (from 2 g/kg to 8 g/kg). These results suggest that the present doses of green tea powder supplementation in broiler diets do not improve performance or oxidative capacity, and additional studies are warranted to better identify the optimal inclusion levels.

Özet

Bu çalışmanın amacı, broyler civcivlerin rasyonlarına ilave edilen yeşil çay tozunun büyüme performansı ve bazı kan metabolitleri üzerindeki etkilerini belirlemektir. Araştırmada, günlük yaşta erkek Ross 308 broyler civcivler, benzer başlangıç canlı ağırlığına sahip olacak şekilde (42,49±0.32 g/civciv) her birinde 20 hayvan bulunan dört deneme grubuna ayrılmıştır. Hayvanlar, 5 hafta boyunca ya bazal rasyonla (kontrol grubu) ya da sırasıyla 2, 4 ve 8 g/kg düzeylerinde yeşil çay tozu ilave edilmiş rasyonlarla beslenmiştir. Yem ve su ad libitum olarak verilmiştir. Denemede büyüme performansı, karkas özellikleri ve kan metabolitlerine [toplam antioksidan durumu (TAS), toplam oksidan durumu (TOS), alanin aminotransferaz (ALT) ve aspartat aminotransferaz (AST)] ilişkin veriler toplanmıştır. Sonuçlar, yeşil çay tozu ilavesinin kontrol grubuna kıyasla broylerlerde performans ve karkas kesim özelliklerini etkilemediğini göstermiştir. Buna karşın, yeşil çay tozu takviyesi (2 g/kg'dan 8 g/kg'a kadar) serum oksidatif stres indeksi ve ALT aktivitelerini artırmıştır. Bu bulgular, broyler rasyonlarına mevcut dozlarda yeşil çay tozu ilavesinin performansı veya oksidatif kapasiteyi iyileştirmediğini göstermekte olup, en uygun kullanım düzeylerinin belirlenebilmesi için ilave çalışmalara ihtiyaç duyulduğunu ortaya koymaktadır.
