“…EW, PD and ED values were 75.54 ± 8.07 g, 5.25 ± 0.80 cm and 3.45 ± 0.81 cm, respectively. These data are different from those reported in local turkeys raised in regions of Nigerian (Adeyeye, 2009;Isidahomen et al, 2014;Popoola et al, 2015), Croatia (Galic et al, 2017), Bulgaria (Hristakieva et al., 2017) and India (Anna-Anandh et al, 2012). Previously, it has been described that, in this poultry species, the main factors that influence the variation of external egg traits, mainly in weight, are the genotype (Isidahomen et al, 2014), the phenotype (Juárez-Caratachea et al,2018) and the age of the birds (Ghane et al, 2015;Mróz et al, 2019).…”

This study aimed to evaluate external and internal quality traits and determine prediction equations for some of these traits in eggs of Mexican native turkey hens. A total of 72 eggs from native turkey hens in the laying stage raised in rural municipality of Villaflores, Chiapas were measured. The external traits evaluated were: egg weight (EW), polar diameter (PD), equatorial diameter (ED), egg shape index (SI), shell weight (SW), shell percentage (SP), egg surface area (ESA) and shell weight per unit surface area (SSA). The internal traits were: albumen height (AH), yolk height (YH), albumen weight (AW), yolk weight (YW), Haugh units (HU), albumen percentage (AP), yolk percentage (YP) and yolk color (YC). The data were analyzed with descriptive statistics and Pearson correlation coefficients (r) and linear regression using the SAS program, ver. 9.4. The values obtained for the external egg quality traits showed greater variability. Pearson's correlation coefficients between external and internal traits were positive and moderately significant (P <0.05), as well as highly significant (P <0.0001), and ranged from r = 0.31 (EW vs PD) to r = 0.99 (ED vs ESA). All linear regression equations to predict EW, SW, AW and YW were found to be significant (<.0001). The best predictors of EW were PD, SI, SW and ESA (R2 = 76%). SW and YW traits can be adequately predicted using the EW and SI values together (R2 = 59% and R2 = 74%, respectively), while the AW can be predicted from the EW (R2 = 33%). Based on the results obtained, it is suggested to implement selection programs to improve the quality parameters of the native turkey hen egg in Mexico.

“…Telur burung Gosong Filipina (Megapodius cumingii) Data karakteristik warna, bentuk dan tekstur telur burung filipina didukung oleh data pada spesies megapoda yang lain yaitu pada burung maleo dan burung mamoa. Sifat fisik, morfologi, dan mekanik telur memegang peranan penting dalam proses perkembangan embrio dan penetasan telur [18]. Selanjutnya dilaporkan juga bahwa parameter morfometrik telur seperti bobot telur, lebar telur, bobot albumen dan kuning telur sangat penting pada unggas karena faktor tersebut mempengaruhi kualitas dan penilaian telur serta perkembangan embrio [19].…”

This research was conducted to examine the physical characteristics, chemical composition of the eggs of the filipina gosong bird (Megapodius cumingii) obtained from nesting sites on the coast of Poat Island, Pagimana District, Banggai Regency, Central Sulawesi Province. Measurement of the physical characteristics of eggs (weight, diameter, length and egg index) were carried out at the Laboratory of Biology Study Program, Tadulako University. Besides, observation on egg color, shape and egg texture were also conducted. Measurements of water and fat content, protein, carbohydrates, ash, crude fiber and egg antioxidants (Proxymate analysis) were carried out at the Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Tadulako University. Amino acid analysis was carried out at the Integrated Laboratory of IPB by using HPLC (High Performance Liquid Chromatography). The results showed that the eggs of the Filipina charred bird had an oval shape with two shell colors, dark brown and light brown, and the texture was smooth. The average size of egg weight, length, diameter and egg index were 99.35 g, 7.31 cm, 5.5 cm and 72.43%, respectively. The results of the chemical analysis of filipino gosong eggs revealed that water and fat content, protein, carbohydrates, ash, crude fiber and egg antioxidants were 50.45%, 18.75%, 13.40%, 0.02%, 375.98% and 1.82% respectively. The result showed a higher protein content compared to fat content. The 17 types of amino acids included essential and non-essential amino acids. Glutamate was the highest concentration of 2.10%, while cysteine was the lowest concentration of 0.15%.

Özet: Çalışma kaz, ördek ve hindi kanatlı hayvan türlerinin yumurtalarına ait dış kalite özellik değerlerini belirlemek amacıyla yapılmıştır. Çalışmanın materyalini Konya ilinde halk elinde yetiştirilen kaz, ördek ve hindilerden temin edilen toplam 440 adet kaz (n=117), (n=260) ördek ve hindi (n=63) yumurtası oluşturmuştur. Her bir yumurta bireysel olarak tartılmış olup yumurta boyu ve eni saptanmıştır. Ölçümle belirlenen bu üç değer kullanılarak matematiksel denklemler yardımıyla yumurta dış kalite özellik değerleri tespit edilmiştir. Yumurtaların şeklini tanımlamada şekil indeksi ve elongasyon değerleri kullanılmıştır. Kaz, ördek ve hindi yumurta kabuk özellikleri olarak kabuk ağırlığı (11.32 ve 11.23 g; 5.69 ve 5.71 g; 5.31 ve 5.33 g), kabuk kalınlığı (0.45 ve 0.48 mm; 0.35 ve 0.35 mm; 0.32 ve 0.34 mm) ve kabuk yoğunluğu (2.08 g/cm 3 ; 2.06 g/cm 3 ; 2.06 g/cm 3) sırasıyla belirlenmiştir. Ayrıca yumurta kabuk yüzey alanı ve yumurta kütlesi saptanmıştır. Kaz, ördek ve hindi yumurtalarına ait şekil indeksi ve elongasyon değerleri sırasıyla %68,13±0.39 ve 1.47±0.01, %71,76±0.19 ve 1.40±0.00, %72,53±0.32 ve 1.38±0,01 olarak tespit edilmiştir. Bu çalışmada, yumurta ağırlığı, yumurta boyu ve eni baz alınarak bazı küçük beden yapısına sahip kanatlı hayvanların yumurta özellikleri için belirlenen matematiksel formüller yardımıyla kaz, ördek ve hindi kanatlı türlerinin yumurta dış kalite özellik değerleri hesaplanmıştır.
