“…The values of the eggshell quality parameters (Table 1) found for eggs of both species remained within the standards found in the literature for shell of good quality, based on specific gravity analyses in hen eggs (SILVA, 2004). ) and of quails (MUNIZ et al, 2015); eggshell thickness in hen eggs (STADELMAN and COTTERILL, 1995) and of quails (BARRETO et al, 2007;SILVA et al, 2010;LEMOS et al, 2012) breaking resistance and percentage of egg shell in hens (OLIVEIRA et al, 2014) and percentage of shell in quail eggs (LEMOS et al, 2017) and breaking strength in quail eggs (VIEIRA FILHO et al, 2016).…”

Sixty fresh hen eggs and 60 quail eggs were used in an experiment conducted at UFRRJ in order to survey the correlation between the eggshell quality measurements by average of the following parameters: specific gravity, breaking strength, percentage and thickness of the shell. For hen eggs, specific gravity demonstrated a higher correlation (p <0.05) with shell thickness as compared to other methodologies; the breaking strength correlated with the shell percentage and shell thickness. In quail eggs, there was no correlation (p> 0.05) between specific gravity with the other shell quality analyses. There was a correspondence between breaking strength with the percentage and the thickness of the shell, this ratio was higher for the percentage of shell. For hen eggs, the measurement of the specific gravity method used in commercial poultry farms was adequate to indicate good shell quality in accordance with great correlation with shell thickness. However, the evaluation of shell quality through the specific gravity for quail eggs needs adaptation in the methodology for egg morphology for this species. The parameters of shell quality surveyed: specific gravity, breaking resistance, percentage of shell and thickness of shell in hen eggs showed a positive correlation to a moderate degree (0.54). For quail eggs, the shell percentage shows moderate match (0.60) only with breaking strength and shell thickness.

“…Among the difficulties found in the production of quails, we can mention the quality of eggs, most notably the quality of shells, which is affected by bird age, bird nutrition, and heat stress (SILVA et al, 2018). It is possible to evaluate this parameter in the field, where shell thickness, shell percentage and shell weight are measured (LEMOS et al, 2017). The shell quality is also directly related to storage in the case of unrefrigerated eggs kept at room temperature because of the porosity of the shell.…”

The aim of this study is to evaluate the influence of including levels of calcareous seaweed flour in replacement for calcite limestone on the diet under egg conservation at different storage periods. 140 Japanese quails were used in a completely randomized experiment consisting of a 4x4 factorial design. The factorial design was four inclusions of calcareous seaweed (0%, 10%, 20%, and 30%) and four storage periods (zero, seven, 14, and 21 days) with ten replications of three eggs each. The egg quality variables were evaluated. Data were subjected to analysis of variance using Tukey test and polynomial regression at a 5% significance level. There was no interaction effect between the factor's storage time and inclusion of calcareous seaweed (p>0.05). There was an increasing linear effect on shell weight and thickness in relation to inclusion levels of calcareous seaweed. There was an individual effect of egg storage time (p>0.05) on egg weight, yolk color, albumen and yolk height, yolk weight and percentage, albumen, yolk index, yolk diameter, specific gravity, and Haugh unit. The inclusion of up to 30% of calcareous seaweed in replacement for calcite limestone in the diet of Japanese quails improves the weight and thickness of eggshells but does not influence the conservation of the eggs up to 21 days of storage.

This study aimed to evaluate the influence of homeopathic products in diets of quails in the egg quality when submitted to different storage periods. In the trial we used 200 Japanese quails in a completely randomized design with 4 diets: reference diet, vehicle used in homeopathic products and 2 homeopathic products - Fertsigo® and Ovosigo® with ten replicates of three eggs in each. Egg quality parameters were evaluated during 3 storage periods. Data were evaluated as repeated measures in time, the effects of the interactions between treatments and time as well as their isolated effects were verified. There was the interaction between homeopathic products and storage time in the parameters of albumen and yolk height, Haugh unit, and yolk index, in which a reduction was obtained over time. For egg weight, yolk, albumen and shell, percentage of albumen, and percentage of eggshell there was a significant effect only for homeopathy. The inclusion of homeopathic additives increased egg weight. It is indicated the addition of the product with homeopathic basis Ovosigo® and FertSigo® in diets of Japanese quails in the laying phase resulting in better egg and components but did not influence the quality maintenance of eggs of Japanese quails in the periods evaluated.
