Abstract

This study was designed to investigate the effects of non-ventilated incubator conditions during the first 10 and 14 days of incubation on fertile hatchability and 6 wk live performance of broiler chickens progenied from those treatments. Hatching eggs were obtained from broiler breeders (Ross 308) at 35 weeks of age. A total of 1152 eggs were used in the present study. All eggs were equally and randomly distributed into 3 incubators. The eggs of 3 groups were incubated under identical conditions at a set point 37.6 °C and a RH of 58% in setters for first 18 d of incubation. However, the ventilations procedures of the 3 groups were not identical. The first group were not ventilated from 0 to 10 d of incubation (NoV-10 d), whereas second group were not ventilated from 0 to 14 d of incubation (NoV-14 d). Thereafter, the NoV-10 d and NoV-14 d groups were incubated under standard conditions. The third group was designed as control and incubated under standard hatchery conditions during the whole incubation period. Newly hatched chicks were placed in floor pens and reared on common fed on , commercial feeds and reared under standard management conditions from 1 to 6 wk of age. There were found that hatchability was improved in eggs incubated under the non ventilated incubator conditions until day 10 and 14 compared to control eggs. The time of hatch in chicks incubated under No V-14 d conditions delayed. Throughout rearing, live body weights and FCR values were better in NoV-10 d than that of Nov-14 d and control groups. Data in the current study suggest that exposure of the embryos to the NoV environment during the first 10 d or 14 d of incubation resultedin positive effects on, fertile hatchability and some live performance parameters of progeny birds.

Özet

Bu çalışmada, broylerlerde kuluçkanın ilk 10 ve 14 günlük döneminde havalandırmasız kuluçka makine şartlarının kuluçka sonuçları ile aynı yumurtalardan çıkan civcivlerde çıkış sonrası 6 haftalık periyottaki performansa etkileri araştırılmıştır. Araştırma materyali olan 1152 adet kuluçkalık yumurtalar 35 haftalık yaştaki Ross 308 genotiplerden elde edilmiştir. Yumurtalar 3 adet gelişme kabinine eşit sayıda ve rasgele olarak dağıtılmışlardır. Makinelerde ilk 18 günlük kuluçka periyodu için sıcaklık 37,6 0C ve nem % 58 olarak ayarlanmıştır. 1. makinedeki yumurtalar ilk 10 gün havalandırmasız (NoV–10 d), 2. makinedekiler ise ilk 14 gün havalandırmasız ortamda (NoV–14 d) bırakılarak, tamamen kapatılmıştır. 3. makine ise kontrol grubu olarak planlanmış ve tüm kuluçka süresince standart kuluçka şartları uygulanmıştır. Çıkan civcivler kuluçkadaki orijinlerine göre planya talaşı serilen altlıklar üzerinde 6 haftalık yaşa kadar standart yetiştirme şartlarında büyütülmüşlerdir. Çıkış gücü (ÇG) bakımından 10 ve 14 günlük deneme gruplarında ortalamalar kontrol grub ortalamasına göre daha yüksek bulunmuştur. Çıkış zamanı bakımından 14 günlük grup, 10 günlük ve kontrol grup ortalamalarına göre daha geciken bir çıkış eğilimi izlemiştir. Büyütme döneminde, canlı ağırlık ve FCR değerleri bakımından NoV–10 d grup ortalaması NoV–14 d ve kontrol grup ortalamalarına göre daha yüksek bulunmuştur. Çalışma sonuçlarına göre kuluçkanın ilk 10 ve 14 günlük periyodu boyunca havalandırmaların kapatılması gerek kuluçka gerekse çıkış sonrası performans değerleri bakımından faydalı olacağı kanaatine varılmıştır.
