The Effects of Adding Oxygen in Incubator at High Altitude (1700 M) and Different Genotypes on Hatching Results and Subsequent Performance
Abstract
Bu çalışmanın amacı yüksek rakımda (1700m ) kuluçka makinesine oksijen eklenmesinin ve farklı genotiplerin kuluçka sonuçlarına ve daha sonraki performansa etkilerini araştırmaktır. 42-44 haftalık yaştaki iki farklı ebeveynden elde edilen 984 adetyumurta tesadüfi olarak iki makineye yüklenmiştir. Kuluçkanın 18-21. günler arası makinelerden birine oksijen eklenerek makine içi oksijen düzeyi % 24.5 ± 0.5 olacak şekilde düzenlenmiştir. Diğer makine kontrol grubu olarak tanımlanmış olup oksijen ilave edilmemiştir. Kuluçkanın 21. günü çıkan civciv sayısı tespit edilmiştir.Kuluçkanın 21. gününde çıkış olmayan tüm yumurtalar açılmış, makroskopik olarak incelenmiş ve döllülük ve embriyonik ölümler tespit edilmiştir. Çıkan civcivler ZiraatFakültesinin Tavukçuluk Araştırma Ünitesine transfer edilmiştir.Çalışma sonucunda oksijen eklenmesinin İP (%), ÇG (%), DP (%), EDÖ (%) veGDÖ (%) üzerine etkisi önemli olmuştur (P<0.01). Genotipin İP (%), ÇG (%), EDÖ(%), GDÖ (%) ve civciv çıkış ağırlığı üzerine etkisi önemli olmuştur (P<0.01). EDÖ(%) ve YAK (%) özellikleri üzerinde Genotip ve oksijen eklenmesinin interaksiyon etkisi önemli olmuştur. 42. gün canlı ağırlık ve YYO üzerine genotip ve oksijen eklenmesinin etkisi de önemli olarak saptanmıştır.Sonuç olarak, yüksek rakımda kuluçka makinesine oksijen eklenmesi işlemi kuluçka randımanını optimize etmek ve daha sonraki etlik piliçlerin performanslarınıgeliştirmek için göz önünde bulundurulmalıdır.
The purpose of this study was to examine the effects of adding oxygen in incubator at high altitude (1700 m) and different genotypes on hatching results and subsequent performance. All eggs (984 number) from two genotypes eggs which was produced by breeders of 42 or 44 wk of age were distributed randomly into two hatching cabinets which were operated. The first cabinet was oxygenated at 25 %whereas no oxygen added to the second cabinet between days 18 and 21 incubation and called control group. The number of chicks hatching was recorded day 21. At day 21 of incubation, all unhatched eggs were opened and examined macroscopically for true fertility or the time of embryonic death. At hatch the chicks were transferred to the broiler rearing facilities at the research Chicken coop farm of Agricultural Faculty.In the result of the study, IP (%), FH (%), EP(%) EPM (%) and LPM (%) was significantly affected by Oxygen Supplement (P<0.01). IP (%), FH (%), EPM (%),LPM (%) and initial weight was significantly affected by genotype (P<0.01). There are interaction between genotype and Oxygen Supplement of EPM (%) and EWL (%).Body weight of day 42 and FCR (Feed Conversion Ratio) was affected by oxygen Supplement and genotype.In Conclusion, it is concluded that extra O2 supplementation at high altitudes hasto be considered in order to optimize hatchability and improve subsequent performance of broiler.
