Abstract
Aim: This study was carried out in order to determine the effects of storage length on the hatchability of ostrich eggs obtained from private ostrich farms. Materials and Methods: The eggs, which were collected from ostriches in one season, lasting from March to September, were numbered, weighed, recorded with laying date and stored for 1-15 days. On the 14th day of incubation, infertile eggs were determined and removed from incubation. On the 38th day of incubation, eggs were weighed for the second time, and following weight losses measurement, the eggs were transferred to the hatching machine. The hatched chicks were weighed and hatchability of fertile egg, hatchability of egg set and chick weight results were determined. Results: Average incubation period was 43.58 days. In terms of incubation period, differences between groups that were classified according to storage periods (short, medium and long) were significant (P<0.05). Average egg weight loss of during incubation was 13.70%. Mean hatchabilities of egg set and fertile egg were 57.90% and 75.00%, respectively and differences between the groups of storage period were statistically significant (P<0.05). Conclusions: The storage period more than ten days has the potential to negatively affect the incubation results of ostrich eggs. So, it could be recommended that for storing ostrich eggs, 10 days of storage shouldn’t be exceeded.
Özet
Amaç: Çalışma, özel devekuşu işletmelerden elde edilen yumurtaların depolanma sürelerinin kuluçka performansı üzerine etkilerini belirlemek amacı ile yapılmıştır.Gereç ve Yöntem: Mart ve Eylül ayları arasını kapsayan bir üretim sezonunda elde edilen devekuşu yumurtaları, numaralandırılıp, tartılarak yumurtlama tarihleri ve 1-15 gün arası depolanma süreleri ile birlikte kayıt edildi. 14. günde dölsüzlüğü saptanan yumurtalar kuluçkadan çıkartıldı. İnkübasyonun 38. günündeki ikinci tartımları ile ağırlık kayıpları ölçülen yumurtalar, çıkım makinesine nakledildi. Çıkımı gerçekleşen civcivler de tartılmış, kuluçkaya konan yumurtalar ve döllü yumurtalar için kulakça randımanı belirlendi.Bulgular: Bu çalışmada ortalama kuluçka süresi 43.58 gün oldu. Depolanma süresine göre yapılan gruplar (Kısa, orta ve uzun depolama) için kuluçka süresi ortalamaları arası farklılıklar istatistikî olarak önemli (P
