Abstract

This study was conducted to investigate the effects of heat conditioning and dietary ascorbic acid supplementation on growth performance, carcass and meat quality characteristics in heat-stressed broilers. A total of 320 male broilers were randomly assigned to 4 treatment groups as positive control (PC), heat stress (HS), heat conditioning (HC) and ascorbic acid supplementation (AA). Broilers in PC group were housed in thermoneutral conditions (24oC) and fed with the basal diet throughout experimental period. Heat stress group was exposed to 35oC for 6 h daily between 4 and 6 weeks and fed with basal diet throughout experimental period. Heat conditioned group was exposed to 36oC at 5 d of age for 24 h, fed on the basal diet throughout experimental period and was exposed to 35oC for 6 h daily between 4 and 6 weeks. Ascorbic acid supplemented group was fed a diet supplemented with 500 mg/kg L-ascorbic acid and was exposed to 35oC for 6 h daily between 4 and 6 weeks. Heat stress significantly decreased final body weight, weight gain (P

Özet

Bu araştırma, sıcak stresi altındaki broylerlerde erken dönem sıcağa alıştırma ve rasyona askorbik asit ilavesinin büyüme performansı, karkas ve et kalite özellikleri üzerine etkilerini araştırmak için yapılmıştır. Toplam 320 adet erkek broyler pozitif kontrol (PC), sıcak stresi (HS), erken dönem sıcağa alıştırma (HC) ve askorbik asit ilave edilen rasyonla besleme (AA) olmak üzere dört gruba ayrılmıştır. PC grubundaki broylerler deneme süresince termonötral koşullarda (24oC) yetiştirilmiş ve bazal rasyonla beslenmiştir. HC grubu, 5 günlük yaşta 24 saat 36oCye maruz bırakılmış, deneme süresince bazal rasyonla beslenmiş ve 4-6. haftalar arasında günde 6 saat 35oC sıcaklığa maruz bırakılmıştır. AA grup, 500 mg/kg L-askorbik asit ilave edilen rasyonla beslenmiş ve 4-6. haftalar arasında günde 6 saat 35 oC sıcaklığa maruz bırakılmıştır. HS grubundaki broilerler, 4-6. haftalar arasında günde 6 saat 35oC sıcaklığa maruz bırakılmış ve deneme süresince bazal rasyonla beslenmiştir. Sıcak stresinin final canlı ağırlık, ağırlık kazancı (P
