Kuluçkaya Yatırılan Döllenmemiş Emu (Dromaius novaehollandiae) Yumurtalarının Bazı Özelliklerinin Belirlenmesi

Öz

Çalışma Emuların dölsüz yumurtalarında kuluçka öncesi ve sonrasında ağırlık, kabuk özellikleri, iç ortam özellikleri ve ağırlık kaybının belirlenmesi amacıyla yapılmıştır. Çalışmada 2022 yılında Hatay ili Antakya ilçesinde özel bir tesiste yetiştirilen 2 adet dişi Emudan toplanan yumurtalar kullanılmıştır. Kuluçka öncesi yumurta ağırlığı tartılarak belirlenmiş, bu ağırlık değeri kullanılarak yumurta boyu ve yumurta eni formül yardımıyla tespit edilmiştir. Kuluçka sonrasında civciv çıkışı olmayan dölsüz yumurtaların bütün yumurta ağırlığı, içerik ağırlığı ve iç yüzeyi temizlenmemiş kabuk ağırlığı tartılarak saptanmıştır. Kuluçka öncesi yumurta ağırlığı, kabuk ağırlığı, şekil indeksi ve por sayısı verilen sırayla 556,38 g, 59,57 g, %70,36 ve 25174,91-38767,41 adet olarak belirlenmiştir. Kuluçka sonrası yumurta ağırlığı azalmış ve bağıl yumurta ağırlık kaybı %14,90 olarak gerçekleşmiştir. Sonuç olarak, dölsüz Emu yumurtalarının kuluçka öncesi ve sonrası özellikleri belirlenmiş, az sayıdaki bilimsel çalışmaya katkı verilmiştir.

Determination of Some Characteristics of Incubated Unfertilized Emu (Dromaius novaehollandiae) Eggs

Abstract

The study was conducted to determine the weight, shell characteristics, internal characteristics, and weight loss of unfertilized emu eggs before and after incubation. Eggs collected from 2 female Emu raised in a private facility in the Antakya district of Hatay in 2022 were used in the study. Emu eggs were kept at 37.5 oC and 60% humidity and monitored for 56 days. Egg weight was determined before incubation, and using this weight value, egg height, and egg width were determined with the formula. In addition, shape index, elongation, pore count, pore density, shell weight, and egg shell index were determined. After incubation, the whole egg weight, content weight, and weight of the shell with uncleaned inner surface of the unfertilized eggs were determined. Absolute and relative weight loss was determined using pre-incubation and post-incubation egg weight. The mean shell thickness of unfertilized eggs was determined using the mathematical formula
