Abstract: 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 bod… Show more

“…The higher the serum calcium level, the higher the calcium level in the eggshell. The aim of this study was to investigate the effects of dietary supplementation with CaB4O7 (300 mg/kg) on the mineral content of egg and eggshell in layer quails [24,25].…”

“…Obtaining the desired eggshell quality is closely related to the calcium addition at optimum level to poultry diets (Al-Zahrani and Roberts, 2015). Adequate calcium rates depending on the breed used, the calcium/phosphorus ratio, vitamin D content, age and the productive phase (Attia et al ., 2020; Zhao et al ., 2020; Stanquevis et al ., 2021; Tufarelli et al ., 2021). Among those factors, the relationship between layers, age and the calcium content on quality egg have been extensively studied (Swiatkiewicz et al ., 2018; Kakhki et al ., 2019; Attia et al ., 2020; Wang et al ., 2021).…”

“…The minerals, which make up 5% of an animal's body, are among the most important nutrients. Among all minerals, calcium and phosphorus stand out due to their contribution to skeleton formation (80–85%) and their role in egg shells and muscle development, making them essential to animal functions (Stanquevis et al ., 2021).…”
