Abstract
Bu çalışmada, farklı yetiştirme sistemleri ve genotipleri, yumurtacı hibritlerin, davranış, refah, performans ve yumurta kalitesi özellikleri üzerindeki etkisi araştırılmıştır. Araştırmanın hayvan metaryali Lohmann ISL Classic (W) ve Lohmann Sandy (S), Yetiştirme sistemleri ise altlıklı yer sistemi (DL) ve serbest mera sistemidir. Mera sisteminde Mentha piperita (MP), Petroselinum crispum (PC) ve Medicago sativa (MS)'da bitkileri kullanılmıştır. Araştırmada mera alanı kullanımı genotipler arasında ve bitki türleri arasında farklılık göstermiştir (P<0.01). Yetiştirme sistemi ve genotip, toplam tüy skorunu, bazı davranışları, ilk yumurtlama ve %50 yumurta verim yaşını, tavuk-gün yumurta verimini, toplam yumurta ağırlığını ve yumurta büyüklüğü dağılımını etkilemiştir (P<0.01; P<0.05). Yetiştirme sisteminin, yüz uzunluğunun oransal asimetri, yumurtlama döneminde yem tüketimi, yemden yararlanma oranı, yumurta yüzey alanı ve kabuk kalite özelliklerini önemli ölçüde etkilediği belirlenmiştir (P<0.01; P<0.05). Genotip, tavukların ibik yüzey ve rektal sıcaklıkları, yem tüketimi, yumurta şekil indeksini, kabuk kalınlığını, ak ve sari özelliklerini önemli ölçüde etkilemiştir (P<0.01; P<0.05). Sonuç olarak, bitki türleri, yetiştirme sistemi ve genotipi, tavuklarda bazı refah özelliklerini, davranışları, performansı ve yumurta kalitesi özelliklerini modüle etmektedir.
This study investigated the effect of different production systems and laying hen genotypes on welfare, behavior, performance, and egg quality characteristics. Lohmann LSL Classic (W) and Lohmann Sandy (S) genotypes were evaluated in the deep litter system (DL), and free access to outdoor Mentha piperita (MP), Petroselinum crispum (PC), and Medicago sativa (MS). Range use varied between genotypes and among plant species (P<0.01). Both the production system and genotype influenced the total feather score and the proportion of hens expressing some behaviors, age at first egg and 50% egg production, hen-day egg production, overall egg weight, and egg size distribution (P<0.01; P<0.05). It was determined that the production system significantly influenced the fluctuating asymmetry of face length, feed intake during the egg-laying period, feed conversion ratio, egg surface area, and shell quality traits (P<0.01; P<0.05). Hen genotype significantly impacted comb and rectal temperatures, feed intake, shape index, shell thickness, and albumen and yolk traits (P<0.01; P<0.05). In conclusion, the plant species, production system, and hen genotype modulate some welfare traits, behaviors, performance, and egg quality characteristics in hens.
