“…Ao ser formada a casca dos ovos no útero das codornas, esta precisa de um suprimento adequado de minerais, principalmente cálcio e fósforo; sendo assim, a qualidade da casca dos ovos é dependente da quantidade de minerais, que, em sua maioria são fornecidos pela alimentação. Caso ocorra uma deficiência dos minerais Ca e P, esta situação pode ser contornada pela mobilização destes minerais dos ossos, para o útero auxiliando na formação da casca (CARVALHO & FERNANDES, 2013;SOUZA et al, 2017).…”

“…Limited information on nutritional requirements can compromise food costs, in addition to underestimating or overestimating their needs, causing losses to the sector ( Souza et al., 2017 ). From the nutritional point of view, minerals are among the most important ingredients composing 5% of animal body.…”

Calcium and available phosphorus requirements of Japanese quails in early egg-laying stage

et al. 2021

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.

The aim of this study was to evaluate the effect of increasing levels of extruded soybean (0, 7.5, 15, 22.5 and 30%) in soybean meal replacement on the diet of Japanese laying quails on biometry of the tibia and femur bones. A total of 180 female quails of the species Coturnix coturnix japonica with approximately 150 days of life standardized by body weight, distributed in galvanized wire measuring 38 cm long × 40 cm wide × 23 cm height were used. The design was completely randomized (CAD), with five treatments and six replicates containing six birds per replicate. The experiment lasted for 84 days, with three cycles of production, with 28 days each cycle. There was no significant effect (p>0.05) of the inclusion of increasing levels of extruded soybean on the biometrics of the tibial and femur bones, nor was there any adverse effect on the Seedor index of these bones, which shows that they remained the same. with good resistance during all production cycles of these birds. It can be concluded that the use of extruded soybean up to 30% does not negatively influence the tibial or femur biometry of Japanese quails or the Seedor index of these bones, which shows that bone strength was not affected by inclusion of this food.
