Serbest Gezinmeli Sistemde Yem Formu ve Ot Varlığının Etlik Piliçlerde Performans Üzerine Etkileri

Year 2017, Volume: 14 Issue: 1, 34 - 40, 01.05.2017

Abstract

Bu çalışma yem formunun (toz, pelet) ve bitki örtüsü mevcudiyetinin (var, yok) serbest gezinmeli sistemde yetiştirilen yavaş gelişen etlik piliçlerin büyüme performansı, bazı iç organ ağırlıkları ile karkas özellikleri üzerine etkilerini incelemek amacıyla 2x2 faktöriyel düzeninde planlanmıştır. Günlük yaşta toplam 800 adet (Isa-Hubbard Red-JA 87) yavaş gelişen etlik civciv her birinde 50 adet civciv bulunan 4 tekerrürlü 4 gruba ayrılmıştır. Çalışmada canlı ağırlık kazancı ve yemden yararlanma oranı üzerine yem formunun etkisi yeşil ot tüketimine göre daha etkili olmuştur. Denemenin 25-48 ve 49-72 günleri arasında pelet yem verilen etlik piliçler toz yem tüketenlere kıyasla daha fazla canlı ağırlık kazanarak daha iyi yemden yararlanma değeri sergilemişlerdir. Yemin pelet formda hazırlanması 25-48 günler arasında toz forma kıyasla yem tüketimini azaltırken, sonraki dönemlerde bu etkinin ortadan kalkmış ve gruplar arasında yem tüketimi açısından önemli bir farklılık bulunmamıştır. Pelet yem toz yeme kıyasla ve gezinme alanında bitki örtüsünün olup olmamasına kıyasla (1630 ve 1930saatlerinde yapılan gözlemlerde) etlik piliçlerin gezinme alanına çıkış sayılarını arttırmıştır. Toplam 72 gün süreli besinin sonunda kesilen yavaş gelişen etlik piliçlerin karkas randımanı yem formu ve gezinme alanındaki yeşil ot tüketiminden etkilenmemiştir

The Effect of Feed Form and Green Grass Available on Performance of Broiler in Free Range System

Year 2017, Volume: 14 Issue: 1, 34 - 40, 01.05.2017

Abstract

This study was designed to investigate the effect of feed form (ground or pellet) and vegetation cover (available or unavailable) on the growth performance, some organ weights and carcass characteristics of slow growing broiler chickens grown in the free range system in a 2x2 factorial design. A total of 800, day-old slow-growing broiler chickens (Hubbard Isa Red-JA 87) were randomly allotted into 4 dietary treatments, each with 4 replicates of 50 birds. The effect of feed form was much more pronounced than forage intake in terms of body weight gain and feed conversion ratio with significant improvements in favour of pellet feeding regimen. Throughout the experimental periods of 25 to 48 and 49 to 72, chicks fed on pelleted diet gained more body weight which accompanied to lower feed conversion ratio compared to those receiving ground feed. Pelleted diet decreased feed consumption in birds between 25 to 48 days as compared to birds on ground feed. However, this tendency disappeared thereafter and no significant difference was found between treatments all through the experimental periods. Carcass yield of broiler chicks slaughtered at 72 days of age was not significantly affected by either feed form or green grass intake during the outdoor access.
