The effect of dietary supplementation of zinc at toxic level on the performance and the zinc concentrations of some tissues in broilers

Özet: Araştırmada, yumurtadan çıkmadan itibaren dört hafta süreyle diyetlerine toksik düzeyde çinko katılan broyler civcivlerinin performansı ile kan, karaciğer, böbrek, göğüs eti ve kemikte çinko birikimine etkileri incelenmiştir.Denemede 60 adet günlük et tipi Avian hibrit civcivler her birinde 30 adet civciv bulunan biri kontrol, diğeri çinko sülfat (2500 mg/kg yem) ilaveli yemle beslenen grup olmak üzere 2 gruba ayrılarak civ-civ bölmelerine yerleştirilmiştir. Denemenin sonunda, kontrol grubundaki broylerlerin canlı ağırlığının yemlerine çinko sülfat katılan broyler grubundan %282.2 daha yüksek olması istatistiksel yönden önemli bulunmuştur (p

Broyler yemine toksik düzeyde katılan çinko sülfatın performansa ve bazı doku çinko konsantrasyonlarına etkisi

Summary: The aim of this study was to investigate the accumulation of the toxic doses of zinc in several tissues taken with diet and their effects on performance of broiler chicks. For this purpose, 60 one day-old chicks were used and they were evenly divided into two groups consisting controls and experimental broilers. Chicks in group were fed with normal ration, while the experimental group were fed with diets containing 2500 ppm zinc.At the end of the fourth week, the chicks were slaughtered. The average live weight of the control chicks were 282.2 % higher than the experimental group and the difference was statistically significant (p
