Anadolu-T ve Cobb500 Etlik Piliçlerinde Genotip ve Cinsiyetin Refah ve Dalgalı Asimetri Üzerine Etkileri

Öz

Bu çalışma, yerli broiler genotipi Anadolu-T ile ticari genotip Cobb 500’ün refah parametrelerini karşılaştırmak amacıyla yürütülmüştür. Araştırma, Kahramanmaraş Sütçü İmam Üniversitesi’nin tam kontrollü Ar-Ge kümesinde, toplam 240 civciv (her genotipten 120) kullanılarak gerçekleştirilmiştir. Deneme süresince, gelişimsel stabiliteyi belirlemek amacıyla vücut ağırlıkları (BW), rektal sıcaklıklar (RT), tonik immobilite (TI) süreleri ve bilateral vücut ölçümleri ölçülmüştür. 3 haftalık yaşta rektal sıcaklık (RT) genotipten önemli ölçüde etkilenmiş olup, Anadolu-T tavukları Cobb 500’e göre daha yüksek RT değerleri göstermiştir. 6 haftalık yaşta RT, hem genotip hem de cinsiyetten önemli ölçüde etkilenmiştir. Anadolu-T tavukları Cobb 500’e kıyasla yüksek RT değerlerini korurken, dişiler erkeklere göre daha yüksek RT göstermiştir. Tonik immobilite süreleri genotipler arasında istatistiksel olarak anlamlı farklılık göstermemiştir; bu durum her iki grubun da deneysel koşullar altında benzer korku düzeyleri yaşadığını düşündürmektedir. Ayrıca, bilateral ölçümlerden hesaplanan dalgalı asimetri değerleri, her iki genotipin çevre faktörleri ve gelişimsel stabilite açısından benzer performans sergilediğini göstermiştir. Sonuç olarak, yerli Anadolu-T genotipi büyüme hızı açısından ticari eşine göre geride kalmasına rağmen, refah parametreleri açısından Cobb 500 ile karşılaştırılabilir bulunmuş ve sağlıklı bir gelişimsel profil sergilediği belirlenmiştir.

Assessment of the Effects of Genotype and Sex on Welfare and Fluctuating Asymmetry in Anadolu-T and Cobb500 Broilers

Abstract

This study was conducted to compare the welfare parameters of the local broiler genotype, Anadolu-T, with the commercial genotype, Cobb 500. The research was carried out at the fully controlled R&D poultry house of Kahramanmaraş Sütçü İmam University, using a total of 240 chicks (120 from each genotype). During the experiment, body weights (BW), rectal temperatures (RT), tonic immobility (TI) durations, and bilateral body measurements were measured to determine developmental stability. Rectal temperature (RT) at 3 weeks of age was significantly affected by genotype, with Anadolu–T chickens exhibiting higher RT values than Cobb 500. At 6 weeks, RT was significantly influenced by both genotype and sex. Anadolu–T chickens continued to maintain higher RT values than Cobb500, while females showed higher RT than males. Tonic immobility durations revealed no statistically significant differences between the genotypes, suggesting that both groups experienced similar fear levels under the experimental conditions. Furthermore, the fluctuating asymmetry values calculated from bilateral measurements showed that both genotypes exhibited similar performance regarding environmental factors and developmental stability. In conclusion, while the local Anadolu-T genotype lags behind its commercial counterpart in terms of growth rate, it was determined to be comparable to Cobb 500 regarding welfare parameters, demonstrating a healthy developmental pattern.
