A trial was conducted to evaluate quality of quail eggs from two companies (A and B) at two storage times (5 and 15 days after packing). A total of 480 eggs were kept at room temperature and distributed in a completely randomized design in 2x2factorial arrangement (companies and storage time). The results indicated that trays from company B presented higher weight, as well as mean egg weight. However, the eggs in trays from company A showed greater uniformity. Evaluating the external quality, we found that above 90% of eggshell were considered with total integrity, and no difference for this characteristic between companies was found. The eggs from company A presented lower average weight in comparison to those from company B, regarding storage time. No differences were observed between eggs from companies A and B for Haugh unit value. Storage time of 15 days after packing promoted reduction in Haugh unit value in comparison to those stored for 5 days. Quail eggs from company A presented lower variation in weight, although heavier eggs are produced by company B. Internal quality of quail eggs from both companies was similar. Storage time affected eggs 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.

ABSTRACT: This study aimed to evaluate the effect of using lycopene and organic minerals in diets for laying hens on the egg quality and stability of eggs stored for 30 days under different storage environments. An entirely randomized design was adopted in 2x3x3 factorial scheme (mineral sources x lycopene levels x storage periods) with six replicates of eight hens per experimental unit. The experimental diets were: feed containing inorganic minerals (IM) without added lycopene; IM with added lycopene (400mg kg-1); IM with added lycopene (800mg kg-1); organic minerals (OM) without added lycopene; OM with added lycopene (400mg kg-1); OM with added lycopene (800mg kg-1). After 112 days of feeding experimental diets, it was selected 60 eggs treatment-1, which were later labeled, stored in room and refrigerated temperature, and subjected to different storage periods (0, 15 and 30 days). Variables analyzed were: Haugh unit, yolk index, yolk color, albumen and yolk pH, and lipid oxidation (TBARS). Stability of eggs is not altered as a function of mineral sources and levels of lycopene studied. However, increasing storage time affects the quality of the eggs of laying hens at both storage conditions.

This study aimed at evaluating the internal and external quality of brown-shelled eggs commercialized in the municipality of Parintins-AM. A total of 540 eggs were evaluated and distributed in a completely randomized design, which consisted of three treatments and six replications of 30 eggs each. The treatments were: eggs sold in supermarkets; in grocery stores; and eggs sold directly at the farm. The age of the eggs from supermarkets and grocery stores was unknown, however, the eggs bought at the farm were marketed as being from the day of laying. The collected data were submitted to analysis of variance and Tukey test at 5% probability. There were no differences (p > 0.05) of treatments in the percentage of dirty eggs, however, grocery and farm eggs presented higher (p < 0.05) crack percentage. The eggs at the farm presented higher incidence (p < 0.05) of internal stains of blood. The weight of the egg and albumen presented no differences (p > 0.05). However, the albumen percentage of the farm eggs was higher than the other treatments (p < 0.05). The percentages for yolk and eggshell weight from the farm eggs were lower than the supermarket and grocery eggs (p < 0.05). For the variables albumen height, Haugh unit, albumen index, yolk and albumen pH, the best results were observed for the farm eggs, however, regarding these variables, eggs sold in supermarkets and grocery stores did not differ from each other.  The brown shell eggs sold in the city of Parintins/AM have high rates of external defects, and the eggs bought directly from the farm presented better internal quality, when compared to eggs sold in different establishments.

Abstract: The objective of this work was to evaluate the influence of the inclusion of soybean (Glycine max) gum in the diet of laying hens on egg production, egg external and internal quality, and economic viability, as well as of temperature and storage time on the oxidative stability of eggs. One hundred and eighty 40-week-old Lohmann-LSL layers were fed 0, 1, 2, 3, 4, and 5% soybean gum in the diet. In the economic analysis, the average productive performance of the layers and the cost of feed were considered. In order to evaluate oxidative stability, eggs were stored at room temperature (~30oC) or refrigerated (5oC) for 0, 7, and 21 days. The inclusion of soybean gum in the diet increased feed intake and also egg production, average weight, and mass. Soybean gum improved external and internal egg quality parameters, but reduced the Haugh unit. Oxidative stability was higher in eggs from hens fed 4% gum, at 5oC, for 21 days; however, the largest economic return was with 1% gum. The inclusion of soybean gum promotes improvements in the production, external and internal quality, and oxidative stability of eggs from commercial laying hens.
