Bu çalışma treonine özgü yem seçiminin dişi etlik civciv ve piliçlerin performans ölçütleri ile karkas parametreleri üzerine etkilerini saptamak amacıyla düzenlenmiştir. Denemede 1 günlük 30 adet Ross 308 dişi civciv bireysel olarak 2 muamele grubuna dağıtılmıştır. Sonuçlar yem seçiminin canlı ağırlık kazancı, yem tüketimi ve yemden yararlanma oranını etkilemediğini göstermiştir. Ayrıca karkas parametreleri de deneme gruplarından istatistikî olarak etkilenmemiştir. Kanatlı yetiştiriciliğinde lizin ve metioninden sonraki üçüncü sınırlayıcı amino asit olan treonin (Ayaşan, 2005; Baylan ve ark., 2006; Ayaşan ve ark., 2009), renksiz veya açık sarı kristaller biçiminde görünüşü, hafif kendine has doğal bir kokusu olan bir amino asittir. Yem hammaddelerinde her zaman yeterli miktarlarda bulunmayan treonin özellikle düşük protein içerikli, tahıl ağırlıklı karma yemlerde hayvanların performansını artırmak amacıyla kullanılmaktadır (Ayaşan, 2004).

The Effect of Choice Feeding Based on Threonine on Performance Characteristics and Carcass Parameters of Female Broiler Chicks

Öz

The aim of this study was to evaluate the effect of choice feeding based on threonine on performance characteristics and carcass parameters of female broiler chicks. Day old, thirty Ross 308 female chicks were divided into two dietary treatment groups. Results showed that choice feeding did not affect on body weight gain, feed intake and feed conversion ratio. Also carcass parameters were not significantly affected by experimental treatments.
