The aim of the present study is to characterize the productive capability of Utrerana and to compare the relationships among parameters determining the internal and external quality of the egg, through canonical correlation analysis. A flock of 68 Utrerana hens and a control group of Leghorn hens (n = 17) were housed individually to allow individual identification of eggs and for the assessment of egg quality characteristics. Almost all variables showed differences when both breeds were compared, except for white height, yolk diameter, yolkL* and yolk pH (p > 0.05). Only minor diameter, white height, yolkL*, yolka*, and shell weight reported significant differences between laying age groups. White height, yolk color, and almost all yolk color coordinates were significantly different (p < 0.05) for period and month. Egg and white weight reached highest significantly different levels for the fourth and fifth time that the hens laid an egg. External quality-related traits are better predictors of internal quality-related traits than vice versa, enabling the implementation of an effective noninvasive method for internal quality determination and egg classification aimed at suiting the needs of consumers.

The present study determined, assessed and quantified the exogenous phytase on egg production and egg quality of spent hens. Ninety laying hens (ISA- Brown) received iso-energetic and iso-nitrogenous diet supplemented with 0, 0.05, 0.1, 0.15 and 0.2 % phytase and reared in cages. Each layer was fed 120g feed/day from 90 to 100 weeks of age. At the inception of the study the spent hen at the age of 90 weeks had an average egg production 65.21 %. Phytase addition in diet increased (p<0.05) egg production  (7.67, 12.17, 12.04 and 15.87 % higher than control group), egg mass output (5.5, 9.34, 7.65 and 12.72 % higher than that of control) and feed conversion, but it did not alter shell weight, shell thickness, shape index, albumen index, Haugh unit, per cent yolk and yolk color. It was concluded that reduced egg production of spent hen at older ages to some extent might have a relationship to decreased availability of phosphorus. The decreased egg production in hens at older ages could be corrected by adding appropriate phytase level in the diet. Thus, it may be possible to extend and prolonged productive life of spent hens by supplying exogenous phytase in diet. However, the effect of availability of phosphorus on egg production using larger population for a longer period may be performed to confirm the findings of the current study.

Effect Of Age

The aim was to assess the internal and external quality of consumer eggs of egg‑laying hens of two selected genotypes depending on their age. All of these hens were kept in enriched cages. There were compared eggs from Hy‑Line Brown and ISA Brown hens at the age from 36 to 64 weeks. In total, 3840 eggs from 300 hens were evaluated. Quality of eggs was determined by their technological value. Statistically significant interactions (P = 0.001) between age and genotype were found in all evaluated parameters except for the yolk colour (P = 0.044), whereas there was not found interaction (P = 0.072) between age and genotype in eggshell strength. The significant effect of hens’ age was found in all evaluated parameters, with the only exception of the yolk colour. The results showed that the average weight of eggs, eggshell, albumen and yolk increased with the age. Also the eggshell proportion, its colour and yolk index values ​​increased, whereas the egg shape index, eggshell thickness and strength, albumen proportion, Haugh units, the albumen and the yolk index decreased. Statistically significant effect of the genotype was found in all evaluated parameters except for the yolk index. When comparing both genotypes, the eggs from ISA Brown hens had a better quality. The trend of deteriorating egg quality with age was confirmed.

The developmental and behavioral disabilities remain high in children and in adults who were born preterm. In this case assessment of quality of life and development of preterm infants can be very informative and interesting. This is a prospective longitudinal (at 3, 6, 9 and 12 months) study of preterm birth and term control infants selected from pediatric polyclinics of Yerevan. The quality of life (QL) measures were done with QUALIN questionnaire and the developmental measures with Battelle Developmental Inventory. A total of 71 preterm and 105 term control infants underwent study. Among 71 preterm birth infants, who selected on the study at 3 months, 40 infant's score on the BDI was <–1 SD and 1 infants' score on the BDI was <–2 SD. However, at the age of 12 months 32 of these same children showed a BDI score >85. Parents and pediatricians reported worse QL for of preterm infants compared with control group. At same time parents of preterm infants reported better QL for their children compared with pediatricians. The lowest QL and developmental scores among preterm children were detected at 3 months. Improvement of QL and developmental score was observed in the next age groups.

Internal Quality Assurance

Academic quality is defined as the equivalent to academic standards related to student learning outcomes, which consist of specific levels of knowledge, skills, and abilities achieved by students participating in a program. The achievement of academic standards is accommodated by implementing both internal and external quality assurance practices. Internal quality assurance refers to policies and practices used by the higher education institutions to monitor and improve the quality of their education, while external quality assurance refers to policies and practices set up by external parties to assure the quality of higher education institutions and programs. Petra Christian University has built and implemented its internal quality assurance since 2009 based on its unique quality culture. After its ten-year journey and the achievements that Petra Christian University has reached in 2019, the Industrial Revolution 4.0 and Society 5.0 are challenges ahead that Petra Christian University has to face.

SUMMARY This study was performed to evaluate the effect of the inclusion of paprika and marigold extracts in sorghum-based rations on the productivity and egg quality of laying hens. One hundred sixty laying hens were distributed in a completely randomized design in five treatments and in a factorial arrangement (2 × 2 + 1), one control ration based on corn, two levels of paprika extract (0 and 6 g/kg diet), and two levels of marigold extract (0 and 1 g/kg diet) in sorghum-based rations. There was no effect (P > 0.05) of the treatments on the weight, specific weight, and Haugh unit of the eggs and productive performance, but the inclusion of paprika extract resulted in eggs with lower egg pH. The interaction between the control group and the factorial was significant (P < 0.05) to the laying rate, egg mass, and yolk color, whose values were lower with sorghum-based diets with no pigment compared to control treatment. The interaction between the paprika and marigold extracts was significant increasing the height (P < 0.03) and color (P < 0.0001) of the yolk when paprika extract was used, with or without marigold extract. Marigold extract inclusion reduced the percentage (P < 0.02) and thickness (P < 0.01) of the eggshell. As conclusion, the inclusion of paprika extract in sorghum-based diets for laying hens is viable for improving the egg quality.

The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color, in which the interaction effect between treatments was significant (p < 0.05). The effect of storage time was significant (p < 0.05) for albumen weight, albumen percentage, yolk color, albumen height, specific gravity, and Haugh unit, with reduction of these parameters over the evaluation period. The use of paprika and marigold flower extract in the diets of Black Avifran laying hens does not influence egg quality.

The layer poultry is an important activity for food production with high biological value. Measuring egg quality has great relevance to ensure safety and quality products for consumers. Thus, the objective was to evaluate the egg physical quality of four laying hen’s strains. Were used 864 eggs from four laying hens’ lines (Hisex Brown®, Hy-Line Brown®, Isa Label®, and Lohmann Brown®). The experimental design was completely randomized composed of four treatments (strains) with nine replications with four eggs each. Egg weight, egg diameter, egg length, specific gravity, yolk, albumen and shell weight and percentage, Haugh units, and shell thickness were evaluated. There was a significant difference for all parameters evaluated. The Hisex Brown® strain showed the best results for egg diameter, egg length, specific weight, albumen height, Haugh units, yolk weight, albumen%, shell weight, shell%, and shell thickness, while the Hy-Line Brown® produced bigger and heavier eggs, and Isa Label® presented the highest yolk%. The Hisex Brown® strain showed the better physical quality of eggs when compared to the other studied lines, the strain being indicated when the objective is to produce eggs with better internal and external quality.
