Yaz Mevsiminde Yetiştirilen Etlik Piliçlerde Tünek Soğutma ve Tünek Yüksekliğinin Bazı Kemik Dayanıklılık Parametreleri Üzerine Etkisi

Bu çalışma, yaz koşullarında yetiştirilen etlik piliçlerde soğutulmuş tünek kullanımı ve tünek yüksekliğinin tibia kemiği fiziksel (ağırlık, uzunluk, çap, dayanıklılık ve ağırlık-uzunluk endeksi) ve dayanıklılık (dayanıklılık, katılık, esneme katsayısı ve kırılma gücü) özellikleri üzerine etkilerini incelemek üzere yapılmıştır. Bir günlük yaşta 450 Ross-308 civciv çalışmanın materyalini o luşturmuştur.

The Effect of Perch Cooling and Perch Height on Some Bone Strength Parameters in Broilers Reared in Summer

This study was carried out to investigate the effects of perch cooling and two different perch heights on physical (the weight, length, diameter, strength index, and weight-length index) and strength (strength, stiffness, elastic modulus, ultimate force) properties of tibiotarsus of broilers reared in summer conditions. A total of 450 one-d-old Ross-308 broiler chicks were used as the material. Chicks were allocated into 10 pens which has 15 chicks in each as to a 3x2x2 experimental design with three replication. Perch temperature was set to 10oC for cooled perches while perches were attached 7.5 and 15 cm off the floor. The position of both cooled and non-cooled perches were set to make animals pass over the perch for feeding and drinking. Results revealed that tibia weights in both 7.5 (19.39 g) and 15 cm (19.01 g) perch height groups were higher than the no-perch (17.24 g) group (P
