“…Egg weights in this study did not affect the white index value. These results were similar to report of by Ukwu et al (2017), in which light egg weight, medium or heavy did not affect the white index value. Heavy egg weight after storage for 7 days decreased faster than at light or medium weights.…”

The objective of this study was to examine the effect of storage time and egg weight at room temperature on the interior quality of Magelang duck. The material used were 120 eggs of Magelang duck. The parameters observed were albumen index, egg yolk index and Haugh unit. The 4 x 3 factorial experiment with 2 factors was applied. In which the first factor (A) was the length of egg storage of: a1 = 1 day, a2 = 3 days, a3 = 5 days and a4 = 7 days and the second factor (B) was egg weight of b1 (low = 48,4g -63,1g) b2 (medium = 63,2g -73,6g) and b3 (high 73,7g -81g,). The data were analyzed by the General Linear Model (GLM) procedure of Statistical Analysis System (SAS). The result showed that there was no interaction between storage time and egg weight on quality interior. Storage time was significant different (P<0,05) on albumin index, egg yolk index and Haugh unit. Egg weight had no effect on index albumen, egg yolk index and Haugh unit. In conclusion, the quality of the interior began to decline after being saved 3 days and the optimal egg weight for hatching eggs is medium egg weight.

“…Light, medium, and heavy egg weights in this study did not affect the yolk index value. These results were the same as reported by Ukwu et al (2017) that light, medium and severe egg weight groups did not affect the yolk index value. However, the average weight of eggs was lower than the weight of light eggs.…”

“…Yolk diameter and Haugh units reported the best discriminating properties (fourth and fifth position in the rank) after weight-related traits (albumen, eggshell, and yolk weights). The relevance of these traits may be ascribed as suggested by Ukwu et al [ 63 ], who reported significant differences in yolk weight and albumen height among light (less than 49.99 g), medium (50–55 g), and heavy eggs (more than 55 g) of Isa Brown egg layer chickens in Nigeria. This has also been reported by Alkan et al [ 64 ], who addressed a parallel increase in yolk diameter as egg weight increases in partridge eggs.…”

This study aimed to develop a tool to validate multivariety breed egg quality classification depending on quality-related internal and external traits using a discriminant canonical analysis approach. A flock of 60 Utrerana hens (Franciscan, White, Black, and Partridge) and a control group of 10 Leghorn hens were placed in individual cages to follow the traceability of the eggs and perform an individual internal and external quality assessment. Egg groups were determined depending on their commercial size (S, M, L, and XL), laying hen breed, and variety. Egg weight, major diameter, minor diameter, shell b*, albumen height, and the presence or absence of visual defects in yolk and/or albumen showed multicollinearity problems (variance inflation factor (VIF) > 5) and were discarded. Albumen weight, eggshell weight, and yolk weight were the most responsible traits for the differences among egg quality categories (Wilks’ lambda: 0.335, 0.539, and 0.566 for albumen weight, eggshell weight, and yolk weight, respectively). The combination of traits in the first two dimensions explained 55.02% and 20.62% variability among groups, respectively. Shared properties between Partridge and Franciscan varieties may stem from their eggs presenting heavier yolks and slightly lower weights, while White Utrerana and Leghorn hens’ similarities may be ascribed to hybridization reminiscences.

“…The albumen depth, albumen width and albumen length (mm) were also measured with Vernier caliper while the albumen and yolk weights were taken using the Camry sensitive digital weighing scale which was after separating the albumen from the yolk and their ratio calculated. The Haugh unit, yolk index, albumen index and egg shape index were calculated using the equations (Haugh 1937;Ukwu et al, 2017). Haugh unit (HU) = 100 x log (H + 7.6 -0.37…”

The study was conducted to investigate the external and internal egg quality characteristics of two local strains of turkey during their early reproductive age. A total of 96 freshly laid eggs were sampled from two local turkey strains having black and white plumages. The turkeys were 33weeks of age with two months into lay. Data were collected weekly for three weeks on egg weight, egg length, egg diameter, shell thickness, shell weight, shell index, albumen weight, yolk weight, albumen: yolk ratio, albumen length, yolk length, albumen diameter, yolk diameter, albumen height, yolk height, yolk index and Haugh unit and analyzed using the statistical package of SAS. The results revealed that highly significant (p<0.01) differences in the external traits occurred in egg weight, egg length and shell weight with the white turkey strain been superior. Also, the internal traits recorded highly significant (p<0.01) differences in albumen weight, yolk weight, albumen: yolk ratio, albumen length, yolk length and yolk diameter with the white strain performing better than the black strain. Highly significant correlations (p>0.01) exits in most of the correlated traits with the except for Haugh unit that had no significantly (p<0.01) correlations. Thus, since significant variations exits between the two strains, selection activities are recommended to improve these economic traits in egg weight using it has an index in selection and in possible prediction of the quality of poults to be hatched. Also, economically, it may be used to know the consumers' preference on the quality of turkey eggs consumed. L'étude a été menée pour étudier les caractéristiques de qualité externe et interne des œufs de deux souches locales de dinde au début de leur âge de reproduction. Un total de 96 œufs fraîchement pondus ont été échantillonnés à partir de deux souches de dinde locales présentant des plumages noirs et blancs. Les dindes étaient âgées de 33 semaines avec deux mois de ponte. Des données ont été collectées chaque semaine pendant trois semaines sur le poids de l'œuf, la longueur de l'œuf, le diamètre de l'œuf, l'épaisseur de la coquille, le poids de la coquille, l'indice de la coquille, le poids de l'albumine, le poids du jaune, le rapport albumine: jaune, la longueur de l'albumen, la longueur du jaune, le diamètre de l'albumen, le diamètre du jaune, l'albumine hauteur, hauteur du jaune, indice de jaune et unité Haugh et analysés à l'aide du progiciel statistique de 'SAS'. Les résultats ont révélé que des différences très significatives (p = 0,01) dans les caractères externes se produisaient dans le poids des œufs, la longueur des œufs et le poids de la coquille avec la souche de dinde blanche supérieure. En outre, les traits internes ont enregistré des différences très significatives (p = 0,01) dans le poids de l'albumine, le poids du jaune, le rapport albumine : jaune, la longueur de l'albumine, la longueur du jaune et le diamètre du jaune, la souche blanche fonctionnant mieux que la souche noire. Des corrélations hautement significatives (p?0,01) existent dans la plupart des traits corrélés avec l'unité à l'exception de Haugh qui n'avait pas de corrélations significatives (p?0,01). Ainsi, étant donné que des variations importantes existent entre les deux souches, des activités de sélection sont recommandées pour améliorer ces caractères économiques en poids de l'œuf en utilisant un indice de sélection et de prédiction éventuelle de la qualité des dindonneaux à éclore. Aussi, économiquement, il peut être utilisé pour connaître la préférence des consommateurs sur la qualité des œufs de dinde consommés.
