Broiler Civciv Kalitesi ve Skorlama Yöntemleri

Öz

Etlik civcivlerde bir günlük yaştaki civciv kalitesi hem kuluçkahaneler hem de broiler yetiştiricileri açısından büyük önem taşımaktadır. Civciv kalitesi kuluçkahanelerin başarı göstergesi ve broiler yetiştiriciliğinde verimliliğin ön koşuludur. Civciv kalitesi, döllenme anından başlayarak civcivlerin kümeslere yerleştirilme anına kadar birçok faktörden etkilenmektedir. Genel olarak, bu faktörler kuluçka öncesi faktörler ve kuluçka koşulları olarak gruplandırılmaktadır. Bu faktörler embriyo gelişimi, civciv kalitesi ve dolayısıyla çıkış sonrası broiler performansını etkilemektedir. Civciv kalitesi, renk, canlılık, göbek kalitesi, sarı kesesi emilimi, bacak konformasyonu, gaga şekli, civciv çıkış ağırlığı, sarı kesesiz civciv ağırlığı, civciv uzunluğu gibi bazı parametrelerin dikkate alınmasıyla değerlendirilmektedir. Bu parametrelerden bazıları civcivlerin kalitatif, bazıları ise kantitatif özelliklerdir. Bu yüzden, civciv kalitesinin ölçülmesi için görsel skorlama, Tona yada Pasgar skoru, civciv çıkış ağırlığının değerlendirilmesi, sarı kesesiz civciv ağırlığının belirlenmesi, civciv uzunluğunun ölçülmesi gibi bazı skorlama yöntemleri geliştirilmiştir. Bu derlemede, civciv kalitesinin tanımı, civciv kalitesini etkileyen faktörler ve kullanılan skorlama yöntemleri açıklanmıştır
