Abstract

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<0.001). Bones from the cooled perch group were found heavier (19.58 g-109.48 mm) and longer than the no-cooled (18.29 g-105.55 mm) group (P<0.001). As to ultimate force (Fmax), the greatest force (264.2 N) was required for bones in a group with 7.5 cm perch height (P<0.05). There were also similar significant differences in perch cooling and sex parameters while both perch application and perch cooling do not affect bone strength and elastic modulus.

Özet

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. C ivcivler 1 0 a yrı b ölmeye h er b ir grupta 1 5 c ivciv o lacak ş ekilde 3 x2x2 d eneme d üzeni çerçevesinde yerleştirilmiştir. Tünek sıcaklığı 10oC’ye ayarlanmış olup, tünekler tabandan 7.5 ve 15 cm yüksekte olacak şekilde konumlandırılmıştır. Soğutulmuş tünek ve yükseklik gruplarının tamamında tünekler hayvanların yem ve su gibi ihtiyaçlarını gidermek için üzerlerinden geçecekleri şekilde yerleştirilmiştir. Tibia ağırlığı hem 7.5 cm (19.39 g) hem 15 cm (19.01 g) tünek yüksekliklerinde tünek olmayan (17.24 g) gruptan daha yüksek çıkmıştır (P<0.001). Soğutmalı grup (19.58 g- 109.48 mm) tibiaları soğutmasız (18.29 g-105.55 mm) olanlara göre hem daha ağır hem daha uzun olarak bulunmuştur (P<0,001). Kemiklerin kırılması için gereken güce gelince (Fmax); en yüksek güç değeri 264.2 N ile 7.5 cm tünek yüksekliği olan grupta gözlenmiştir (P<0.05). Benzeri önemlilik durumu tünek soğutma ve cinsiyet parametrelerinde bulunamamıştır. Aksine, hem tünek kullanımı hem tünek soğutmasının kemik dayanıklılığı ve dayanıklılık katsayısı üzerine herhangi bir etkisi olmadığı tespit edilmiştir.
