“…The effect seen on EW can be attributed to the ecological characteristics of the species ( Bowmaker and Gous, 1991 ) in preserving embryo competitiveness and maintaining a minimum EW to ensure posthatch survival ( Bowmaker and Gous, 1991 ; Silva et al., 2015a ; Lima et al., 2018 ), with the slightest variation was detected as significant by ANOVA ( Table 3 ). The EW reduction in broiler breeder hens is close to 10% ( Silva et al., 2015b ) and in commercial laying hens it is close to 20% ( Silva et al., 2015a ), whereas for Japanese quails in the present study, a value close to 30% was recorded ( Table 4 ), which was similar to that reported by Sarcinelli et al. (2020) .…”

“…When the dilution technique is used, it is necessary to prove the limitation of the amino acid studied ( Sarcinelli et al., 2020 ; Silva et al., 2019 ). Thus, it is expected that the birds will also respond to L-amino acid supplementation to confirm the limitation generated.…”

“…This was investigated due to reports of arginine having no effect on EP ( Maurício et al., 2016 ; Maurício et al., 2018 ; Tuesta et al., 2018 ). Other studies that also used the dilution technique did not use this amount of rigor to validate the limitation of the amino acid test ( Silva et al., 2019 ; Lima et al., 2020 ; Sarcinelli et al., 2020 ) due to the variability in the responses obtained with this degree of nutritional deficiency. For some categories, body reserve attenuates the additional response ( Silva et al., 2015a ; Lima et al., 2018 ); therefore, in previous studies only the numerical value of the biological response was considered as suitable to prove the dietary limitation of the amino acid test.…”

Were evaluated the effects of substituting limestone with quail eggshell powder on the zootechnical performance, egg quality, and economic efficiency of Japanese quails during peak egg production (11-20 weeks old). The experimental period was 63 days, divided into three 20-day periods. A completely randomized experimental design was used with five treatments (0, 25, 50, 75, and 100% substitution of limestone by eggshell powder), six repetitions, and seven birds per experimental unit, for a total of 210 quails. Feed intake, production of egg/bird/day, egg production per bird housed, marketable egg production, egg viability, feed conversion per egg mass, Seedor index, tibia calcium content, and percentage of calcium excreted were determined. The following variables for egg quality were analyzed: egg weight, specific weight, percentage of egg yolk, albumen and shell, and shell thickness. Economic efficiency was evaluated in fresh and industrialized eggs. Statistical analyses were performed using the SAS software, version 9.2 (2010). Substitution of limestone for eggshell powder had no significant effect on zootechnical performance, tibia calcium content, or egg quality. However, there were significant effects on the percentages of albumen and calcium excreted. The substitution of limestone by eggshell powder in quail feed resulted in higher economic efficiency indexes. These results indicate that the use of 100% eggshell powder in the feed of Japanese laying quails is viable.

A novel source of calcium: effects of calcium pidolate concentration on egg quality in aged laying quails (Coturnix coturnix Japonica)

Calcium content in the diet can affect egg quality and production in aged birds. Calcium pidolate is a new form of calcium supplementation in poultry diets, which favours the absorption of this mineral. The current study was conducted to evaluate the effect of dietary calcium pidolate concentration in the diets of aged laying Japanese quails. A total of 120 female quails (27 weeks old) were assigned to four treatment groups, each with six replicates of five quails per pen. In the 10-week trial, quail diets were supplemented with calcium pidolate at four concentrations (0, 0.25, 0.50 and 1.00 g/kg), providing 25.1, 25.4, 25.8 and 26.5 g/kg calcium, respectively. As a result of this study, body weight, feed intake and feed conversion ratio did not change with the concentration of calcium pidolate (P > 0.05). In contrast, albumen and yolk index decreased as calcium pidolate level increased (P < 0.05). Moreover, calcium pidolate at a concentration of 0.50 g/kg resulted in the greatest egg production, eggshell breaking strength and eggshell thickness (P < 0.05), while above these levels the factors studied were negatively affected. According to these results, the optimal concentration of calcium pidolate in the diets of aged laying quails was 0.50 g/kg.
