“…It is an inevitable phenomenon aggravated by several factors such as the nutritional and sanitary status of the laying hen, egg storage time, and temperature and relative humidity during storage (HENRIQUES et al, 2018). Souza et al (2015) concluded in their study that the inclusion of increasing levels of calcium in the feed is efficient to maintain the internal quality of Japanese quail eggs after storage at room temperature for 14 days, which was not verified in the present study. Based on the results, the increase in shell thickness and weight with increasing inclusion of algae calcareae was not enough to improve the conservation of the internal quality of Japanese quail eggs.…”

“…They are a source of calcium and magnesium that acts as a substitute for calcite limestone (MELO et al, 2009). As Souza et al (2015) reported, calcite mineral supplementation improves eggshell thickness and consequently breakage resistance, suggesting that eggs may have a longer shelf life. The aim of this study is thus 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.…”

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.

“…According to Mello (2015) , approximately 30% of the calcium present in the egg shells comes from the bones, and this is owing to the fact that in the uterus, where the deposition of calcium carbonate in the egg occurs, there is no storage of calcium. Souza et al. (2015) , while using 5 levels of Ca (2.95, 3.25, 3.55, 3.85, and 4.15%) and a 14-day storage period, obtained better internal quality indexes as the levels of Ca increased.…”

An experiment was conducted to estimate the nutritional requirements of calcium ( Ca ) and available phosphorus ( aP ) for Japanese quails ( Coturnix coturnix japonica ) in the egg-laying stage (64–168 D). The experiment was an entirely randomized design, in a factorial scheme (Ca = 1.70, 2.40, 3.10, and 3.80% and aP = 0.15, 0.30, 0.45, and 0.60%), with 3 replicates and 10 quails per experimental unit. No interactions were found for quail body weight and daily feed intake ( DFI ) ( P > 0.05). However, body weight decreased linearly ( P < 0.05) as the levels of Ca increased, whereas DFI exhibited a quadratic effect ( P < 0.05) for both Ca and aP. The lowest values of DFI were estimated in 2.79 and 0.36% for Ca and aP, respectively. Egg production, egg mass, and feed conversion ratio per egg dozen presented significant interaction in which all of them had a quadratic effect ( P < 0.05), with estimations for maximum yield in feed containing 2.74, 2.71, 2.75, and 2.74% Ca and 0.40, 0.39, 0.39, and 0.40% aP. The concentration of Ca in the eggshell increased linearly as per the levels of Ca studied, having a quadratic effect for aP levels, with a maximum point of 0.44%. In relation to the bone parameters, there was a linear interaction for Ca and aP in bone density and bone resistance ( BR ) of the femur, with a quadratic effect in BD estimating 2.84 and 0.50% for Ca and aP, respectively. In BR, the estimation was 3.27% Ca, with linear increase for aP. The BR of the tibiotarso increased linearly as per the Ca levels, obtaining the same Ca concentration response in this bone. As conclusion, when considering the estimations obtained through overlapped contour plots, the best responses to the effects of Ca and aP on productive characteristics were estimated at 2.68% Ca and 0.38% aP to produce feed for egg-laying Japanese quails.
