Özet
Bu araştırma, sıcaklık stresinin etkilerini önlemek amacıyla ısı şoku uygulamasının etlik piliçlerde; dönemlere göre canlı ağırlık, canlı ağırlık artışı, civciv başına yem tüketimi, eklemeli yem tüketimi, yemden yararlanma, kesim ve karkas özellikleri, yaşama gücü ve verim indeksleri belirlemek üzere yapılmıştır. Araştırmada 144 adet ross erkek ve dişi broiler civciv kullanıldı. Araştırmada deneme ve kontrol grubu olarak iki grup ve her bir grupta 12 adet civciv olmak üzere 6 alt gruptan oluşturuldu. Sıcak stresi oluşturulan deneme grubuna 5 günlük yaştaki civcivlere 24 saat süre ile 41°C ısı şoku uygulandı. Çalışma sonunda dönemlere göre canlı ağırlık, canlı ağırlık artışı; kontrol ve deneme gruplarında sırası ile 2 007.04, 1 964.04; ve 1 995.95, 1 934.38 g olarak bulunmuş 1. (145.80,136.26 g), 2. (348.17, 321.20 g) ve 3. (703.55, 648.71 g) günlerde canlı ağırlık bakımından farklılık tespit edilmiştir (P<0.01). Civciv başına yem tüketimi ve yemden yararlanma; deneme ve kontrol gruplarında sırası ile 3 549.99, 1.80; 3 520.61, 1.82 olarak bulunmuştur. Karkas özelliklerinden kalp ağırlığı farklı bulunmuş (P<0.05), diğer karkas özellikleri bakımından farklılık tespit edilmemiştir. Çalışma sonunda yaşama gücü, kontrol ve deneme gruplarında sırası ile % 84.72 ve % 97.22 olarak deneme grubu lehine farklı bulunmuştur (P<0.05). Verim indeksleri deneme ve kontrol grubunda sırası ile 198.98 ve 220.28 olarak bulunmuş ve farklılık tespit edilmemiştir.
This study was carried out to determine the effects of heat shock application for preventing the effects of heat stress on live weight, live weight gain, feed consumption, additional feed consumption, feed conservation rate, slaughter and carcass characteristics, survival rate and yield indexes. 144 male and female ross chicks were used in this research. The chicks were divided into two groups as trial and control group. Both of two groups were divided into six subgroups including 12 chicks randomly. On triaL groups at day 5 heat shock was performed at 41 oC for 24 hours on the chicks which heat stress was exposed. At the end the study according to the stages the live weight gain, in the control and trial groups were found as 2007.04, 1964.04, 1995.95, 1934.38 g respectively. Statistical difference was found in the 1st, 2nd and 3rd days on the live weight (P<0.001). The feed consumption and feed conservation rate per chicks was found to be 3549.99, 1.80; 3520.61, 1.82 in the trial and control groups respectively. Heart weight which is in carcass characteristics found to be statistically different. None of other carcass characteristics was found to be different. At the end of the study survival rate was determined to be % 84.72 and % 97.22 in the control and trial groups respectively and showed statistically difference (P<0.05). Yield indexes were determined as 198.98 and 220.28 in the trial and control groups respectively and statistically difference was found.
