Farklı Zemin Renklerine Sahip Bıldırcın Yumurtası Kabuklarının Çatlak-Kırık Alanlarının Görüntülenmesi

Öz

Yumurta kabuk bütünlüğü, gıda güvenilirliğini, embriyonik gelişimi ve bıldırcın üretiminin ekonomik sürdürülebilirliğini etkileyen kritik bir faktördür. Çatlak ve kırık gibi kabuk kusurları, önemli finansal kayıplara yol açmaktadır. Bu çalışmada, bıldırcın yumurtalarındaki kabuk kusurlarının kabuk zemin rengine (kahverengi-grimsi-beyaz) bağlı olarak görselleştirilmesi ve karakterize edilmesi amaçlanmıştır. Ayrıca, kusurlu yumurtaların ağırlığa dayalı kalite özelliklerinin karşılaştırılması hedeflenmiştir. Çalışma, yumurtlama döneminin altıncı haftasından itibaren toplam 63 gün süreyle yürütülmüştür. Kusurlu yumurtalar günlük olarak toplanmış ve görsel muayene ile kahverengi zeminli (n=40) ve grimsi-beyaz zeminli (n=30) olarak sınıflandırılmıştır. Yumurta ağırlıkları ölçülmüş; bu ağırlık verileri kullanılarak kabuk ağırlığı, kabuk kalınlığı, kabuk oranı, yumurta yüzey alanı ve şekil indeksi gibi temel kalite özellikleri ilgili denklemler aracılığıyla hesaplanmıştır. Kusurlu bölgeler, fotoğrafları çekilerek kaydedilmiştir. İstatistiksel analiz (t-testi), iki renk grubu arasında hesaplanan ağırlığa dayalı kalite özellikleri bakımından anlamlı bir farklılık (P>0.05) olmadığını ortaya koymuştur. Bununla birlikte, kusur görülme sıklığının kahverengi zeminli yumurtalarda, grimsi-beyaz zeminli yumurtalara göre daha yüksek olduğu tespit edilmiştir. Görüntülerin makroskopik analizi, kusur bölgelerinde farklılıklar olduğunu göstermiştir; kahverengi zeminli yumurtaların sivri uç ve ekvator bölgelerinde büyük ve derin kırıklar yaygın olarak gözlenirken, grimsi-beyaz zeminli yumurtalarda ciddi kusurların çoğunlukla ekvator bölgesinde yer aldığı belirlenmiştir. Bu çalışma, bıldırcın yumurtası kabuk kusurları üzerine sınırlı literatüre katkı sağlamayı amaçlayan bir ön çalışma niteliğindedir ve kabuk kırık-çatlak alanlarına ait görsellerin belirlenmesine ve paylaşılmasına olanak tanımaktadır. Bıldırcın yumurtası kabuk kusurlarını detaylandırmak amacıyla, bu çalışmanın bir üretim periyodunu kapsayacak şekilde genişletilmesi için yeni çalışmalar yürütülecektir.

IMAGING OF CRACKED-BROKEN AREAS OF QUAIL EGGSHELLS WITH DIFFERENT GROUND COLORS

Öz

Eggshell integrity is a critical factor influencing food safety, embryonic development, and the economic viability of quail production. Shell defects, such as cracks and breakages, lead to significant financial losses. This study aimed to visualize and characterize shell defects in quail eggs relative to their shell background color (brown-grayish-white) and to compare the weight-based quality characteristics of these defective eggs. The study was conducted over 63 days, beginning from the sixth week of the laying period. Defective eggs were collected daily and visually classified as brown-ground (n=40) or grayish-white-ground (n=30). Egg weight was measured, and key quality traits—including shell weight, shell thickness, shell ratio, egg surface area, and shape index—were calculated using formulas based on egg weight. Defect locations were documented photographically. Statistical analysis (t-test) revealed no significant differences (P>0.05) in the calculated weight-based quality characteristics between the two color groups. However, the incidence of defects was higher in the brown-ground eggs than in the grayish-white-ground eggs. Morphological analysis of the images indicated differences in defect location; large and deep fractures were commonly observed in the pointed end and equatorial regions of brown-ground eggs, whereas in grayish-white-ground eggs, severe defects were most prevalent in the equatorial region. This is a preliminary study to contribute to the scarce literature on quail shell defects, allowing the determination and sharing of visuals of shell fracture-crack areas. Further studies will be carried out to extend this study to cover a production period to detail quail egg shell defects.
