Effects of Free-Range and Deep Litter Housing System on Growth Performance and Production Economics of Slow and Fast-Growing Broiler

Abstract

This study aimed to evaluate the effects of free-range housing system on growth performance and production economics of slow and fast-growing broiler. In the study, slow-growing and fast-growing broilers with slatted floor and deep litter were used, so there were four main groups (2x2), and each main group was consisted of 5 replicates. Each replicates was consisted of 10 male day-old ages chicks so 200 birds were used in total. The experiment lasted in 56 days. In the study, live weight gain, feed consumption, and death of birds were recorded throughout the experiment. Variable costs of each group and their percentages within total costs were calculated, gross profit and profitability were calculated to analyze economic performance. As expected, the body weight and feed conversion ratio of fast-growing broiler was found to be better than slower growings (P<0.001, P<0.006), and the effect of the housing system on live body weight and feed conversion ratio was found to be significantly important (P<0.009, P<0.01). In general, the growth and economic performance of both slow and fast-growing broilers in free-range housing were higher than those raised in conventional deep litter system. According to the results, the use of fast-growing broilers in free-range production and the use of slow-growing broilers in conventional production can be expected to become widespread.

Serbest Dolaşımlı (Free Range) ve Derin Altlık Barındırma Sisteminin Yavaş ve Hızlı Gelişen Etlik Piliçlerde Büyüme Performansı ve Ekonomik Verimlilik Üzerine Etkisi

Abstract

Bu çalışma, serbest dolaşımlı (free-range) barındırma sisteminin yavaş ve hızlı gelişen etlik piliçlerde büyüme performansı ve ekonomik verimlilik üzerine etkisini incelemek amacıyla yapılmıştır. Çalışmada yavaş ve hızlı gelişen iki ayrı etlik piliç genotipi ile serbest dolaşımlı (free range) ve geleneksel derin altlık zemin sistemi olmak üzere dört ana grup yer almış (2x2) ve her ana grup 5 tekrarlı gruptan oluşmuştur. Her tekrarlı grupta 10 adet civciv olmak üzere çalışmada toplamda 200 adet günlük yaşta erkek civciv kullanılmış, gruplarda canlı ağırlık, yem tüketimi ve ölenler kaydedilmiş, değişken giderler ve bu giderlerin toplam içindeki payları belirlenmiş, brüt kar ve karlılık oranı hesaplanmıştır. Araştırma sonu (56 günlük yaş) canlı ağırlık (P<0.009) ve yemden yararlanma oranı (P<0.01) bakımından barındırma sisteminin etkisi önemli bulunmuş, hızlı gelişen genotiplerin deneme sonu canlı ağırlık (P<0.001) ve yemden yararlanma yeteneği (P<0.006) yavaş gelişenlere göre daha yüksek bulunmuştur. Genel olarak, serbest dolaşımlı (free-range) barındırmada yavaş ve hızlı gelişen piliçlerin her ikisinin de büyüme ve ekonomik performansı derin altlık sistemde yetiştirilenlere göre daha yüksek bulunmuştur. Elde edilen sonuçlara göre, hızlı gelişen piliçlerin serbest dolaşımlı free-range piliç eti üretiminde, yavaş gelişen piliçlerin konvansiyonel piliç eti üretiminde kullanımının giderek yaygınlaşacağı beklenebilir.
