Kuluçkalık Bıldırcın Yumurtalarına Çinko-Glisin Enjeksiyonunun Civciv Performansına ve Bazı Dokularda Mineral Birikimine Etkisi

Bu çalışma kuluçkalık bıldırcın yumurtalarına farklı seviyelerde çinko enjeksiyonunun performansa, serum, karaciğer ve kemik mineral kompozisyonuna etkisini belirlemek için yürütülmüştür. Çalışmada 400 adet kuluçkalık bıldırcın yumurtası; NK enjeksiyon yapılmayan kontrol, PK 0.2 ml seyreltici enjeksiyon yapılan kontrol, 20Zn 20 µg/yumurta çinko seviyesinde çinko-glisin + 0.2 ml seyreltici enjekte yapılan ve 40Zn 40 µg/yumurta çinko seviyesinde çinko-glisin + 0.2 ml seyreltici enjekte yapılan grup olacak şekilde dört muamele grubuna dağıtılmıştır. Her muamele grubunda her birinde 25 yumurta bulunan 4 tekerrür bulunmaktadır. Her muamele grubundan 60 adet civciv performans parametrelerini belirlemek amacıyla büyütme kafeslerine konulmuştur. Büyütme periyodunda bütün muamele gruplarına standart bıldırcın büyütme rasyonu verilmiştir. Muamelelerin karkas randımanı, bazı organ ağırlıkları, canlı ağırlık artışı, yem tüketimi, yemden yararlanma oranı, ölüm oranı, serum çinko, kalsiyum ve fosfor seviyeleri, karaciğer fosfor seviyesi, kalsiyum hariç kemik mineral seviyelerine önemli bir etkisi olmamıştır. Serum magnezyum seviyesi, karaciğer çinko, kalsiyum ve manganez seviyeleri ve 5. hafta kemik kalsiyum seviyesi muamele gruplarından önemli derecede etkilenmiştir. Kontrol grubuyla karşılaştırıldığında 20 µg/yumurta çinko enjekte edilmesi ile karaciğer çinko ve manganez seviyesi önemli derecede artmıştır. Bu sonuçlar bıldırcın yumurtalarına 20 µg/yumurta seviyesinde çinko enjeksiyonunun dokularda mineral birikimini olumlu etkilediğini göstermektedir.

The Effect of Injection of Zinc-Glysine on Chick Performance and Mineral Accumulation in Some Tissues in Quail Hatching Eggs

This study was conducted to determine the effect of injection on different levels of zinc to the quail hatching eggs on, performance, serum, liver and bone minerals composition. In the study a total 400 quail hatching eggs were distributed four experimental groups: NK as control non-injected, PK as sham control received 0.2 ml diluents-injected, 20Zn was injected with zinc-glysine at 20 µg zinc per egg, and 40Zn was injected with zinc-glysine at 40 µg zinc per egg. In each experiment group there were four replicates, and in each replicates there were twenty five eggs. Sixty chicks from each treatment were placed in growing cages for the purpose of determining its performance parameters. During the growing period all treatment groups received quail basal diet. The effect of treatment on carcass yield, some organ weights, body weight gain, feed intake, feed conversion ratio, mortality, serum zinc, calcium and phosphorus levels, liver phosphorus level and concentration of bone minerals except calcium level were not significant. The serum magnesium level, liver zinc, calcium and manganese levels, and bone calcium level in fifty week were important in the treatments. The liver zinc and manganese concentrations were significantly increased by 20 μg/egg zinc injection group, in comparison to non-injected group. These results demonstrate that zinc injection at 20 µg/egg level to quail eggs positively affects mineral accumulation in tissues.
