“…Egg shape is influenced by genetic factors and individual traits, and is determined in the oviduct. The egg shape index ranges between 57 % and 92 %, but it is believed that values under and below 74 % are a cause for higher incidence of cracked and broken eggs (Narushin, 2005;Popova-Ralcheva et al, 2009). Values shown are mean ± SD (standard deviation); a -indicates statistical significant difference among breeds (P < 0.05) for the same characteristics As shown Table 2, albumen percentage of tested chickens breed was in interval from 58.29% (Oravka) to 59.41 % (New Hampshire).…”

The present study was conducted to evaluate some parameters of external and internal egg quality of some dual purpose chicken breeds. A total of 500 eggs (100 eggs from each breed) were collected to study for egg (weight, shape index), albumen (weight, percentage), yolk (weight, percentage) and shell (weight, percentage, thickness, strength) quality. The results showed that the egg weight and egg length of New Hampshire were significantly higher (P < 0.05) than that of Oravka whereas difference in egg shape index between these breeds was no significant (P > 0.05). Differences in albumen weight, albumen percentage, yolk weight and yolk percentage of tested dual purpose chicken breeds were statistically no significant (P > 0.05). Albumen height was significantly higher (P < 0.05) in New Hampshire compared with Plymouth Rock Buff and Sussex Light and Haugh unit score were significantly higher (P < 0.05) in New Hampshire compared with Oravka (Slovakian breed), Plymouth Rock Buff, Rhode Island and Sussex Light. The significantly (P < 0.05) higher values of yolk height and yolk index were detected in Oravka than New Hampshire, Plymouth Rock Buff, Rhode Island Red and Sussex Light. The shell weight and proportion were affected by the breed of hens (P < 0.05) but there were no significant differences (P > 0.05) in egg shell thickness and strength.

“…Finally eggshell samples were taken from sharp region, blunt region and equatorial parts of each egg were measured with micrometer with an accuracy of 0.01 mm, and the average eggshell thickness was obtained from the average values of these three parts [16] . The other quality traits were evaluated by methods described [17][18][19][20][21] . Data were subjected to analysis using SPSS 17.0 [22] .…”

Values of egg weight, egg length, egg width, eggshape index, eggshell weight, eggshell ratio, eggshell thickness, eggshell surface area, unit surface area and egg volume were determined as 40.14 g, 49.47 mm, 37.89 mm, 0.76%, 6.48 g, 16%, 0.54 mm, 65.69 cm 2 , 0.11 g/cm 2 and 38.21 cm 3 , respectively. In addition, values of yolk weight, yolk height, yolk width, yolk index, yolk ratio, albumen height, albumen width, albumen length, albumen weight, albumen index, yolk/albumen ratio and haugh unit were found as 13.58 g, 14.99 mm, 40.64 mm, 37%, 33%, 4.77 mm, 62.97 mm, 80.07 mm, 21.62 g, 6.7%, 68% and 74.97%, respectively. According to the results determined in this study, all most all external quality traits of the egg were changed at the significant levels depending on the change occurred in the egg weight. The results indicated that egg weight influences external egg quality traits of quinea fowl. The positive correlations obtained among the egg quality traits indicated that they can be improved phenotypically through selection.

Bu amaçla toplam 100 adet Beç tavuğu yumurtası kullanılmıştır. Araştırma Akdeniz Üniversitesi Ziraat Fakültesi Zootekni Bölümü Hayvancılık Birimi'inde yürütülmüştür. Yumurta ağırlığı, yumurta uzunluğu, yumurta eni, şekil indeksi, kabuk ağırlığı, kabuk oranı, kabuk kalınlığı, kabuk yüzey alanı, birim yüzey alanı ve yumurta hacmi sırasıyla 40.14 g, 49.47 mm, 37.89 mm, %0.76, 6.48 g, %16, 0.54 mm, 65.69 cm 2 , 0.11 g/cm 2 ve 38.21 cm 3 olarak bulunmuştur. Ayrıca, sarı ağırlığı, sarı yüksekliği, sarı genişliği, sarı indeksi, sarı oranı, ak yüksekliği, ak genişliği, ak uzunluğu, ak ağırlığı, ak indeksi, sarı/ak oranı ve haugh birimi de sırasıyla 13.58 g, 14.99 mm, 40.64 mm, %37, %33, 4.77 mm, 62.97 mm, 80.07 mm, 21.62 g, %6.7, %68 ve %74.97 olarak hesaplanmıştır. Yumurta ağırlığındaki değişmeye bağlı olarak yumurtanın dış kalite özellikleri önemli derecede değişmiş ve yumurta ağırlığı dış kalite özelliklerini etkilemiştir. Yumurta kalite özellikleri arasında ortaya çıkan önemli korelasyonlar bu özelliklerin fenotipik olarak seleksiyonla iyileştirilebileceğini göstermiştir.

“…Finally, eggshell samples were taken from the sharp region, the blunt region and the equatorial parts of each egg were measured with micrometre to an accuracy of 0.01 mm, and the average eggshell thickness was obtained from the average values of these parts (Tyler 1961;Alkan et al 2013). The other quality traits were evaluated according to the following equations (Yannakopoulos & Tserveni-Gousi 1986;Narushin 2005;Alkan et al 2013):…”

In this study, the aim was to determine the internal and external quality traits of partridge (Alectoris chukar) eggs as well as the Pearson correlation coefficients among these traits. For use in this research, a total of 200 partridge eggs were collected over three sequential days. The partridges were housed at the Research Unit of Animal Science, Faculty of Agriculture, University of Akdeniz. The eggs were categorized according to weight and classified as ≤19.0 g, 19.1-20.0 g, 20.1-21.0 g and ≥21.1 g. Average eggshell thickness was highest in groups of 20.1-21.0 g and ≥21.1 g. In contrast, lowest eggshell weight was calculated in groups of ≤19.0 g and 19.1-20.0 g. In this study, egg shape index, yolk index, Haugh unit, albumen width and unit surface shell weight were not significantly affected by egg weight groups. Whereas egg length, egg width, shell weight, shell thickness, shell surface area, egg volume, yolk weight, yolk height, yolk width, yolk ratio, albumen height, albumen length, albumen weight, albumen index, albumen ratio and yolk/albumen ratio were significantly affected by egg weight groups. At the same time, there was found a significant relationship amongst the internal and external egg quality traits.
