In tropical and subtropical climate regions, heat stress is one of the main causes of production losses in laying quails, aggravated by the antinutritional effects of the phytate in diet ingredients, which negatively affect the bioavailability of minerals, especially calcium and phosphorus. This situation results in a reduction in production and the quality of eggs from commercial laying quails. Several nutritional strategies are utilized to reduce the adverse effects of high temperatures and antinutritional factors such as phytate. Among these strategies, the use of exogenous enzymes, such as phytase, stands out as a viable alternative. Phytase breaks down phytate molecules, optimizing the absorption of essential minerals and improving productive performance and egg quality under unfavorable conditions. Specifically, it is recommended to use 1500 FTU of phytase, as it not only reduces the effects of thermal stress but also enhances eggshell thickness and calcium absorption. In this context, this bibliographic review sought to produce a document demonstrating the beneficial effects of the phytase enzyme on the hydrolysis of the phytate molecule, the availability of calcium for Japanese quails (), and its implications in thermal stress due to heat.
在热带和亚热带气候地区，热应激是蛋鹌鹑生产损失的主要原因之一，日粮成分中植酸盐的抗营养作用会加剧这种情况，植酸盐会对矿物质尤其是钙和磷的生物利用率产生负面影响。这种情况导致商业蛋鹌鹑的产蛋量和蛋品质下降。人们采用了多种营养策略来减少高温和植酸盐等抗营养因子的不利影响。在这些策略中，使用外源酶如植酸酶是一种可行的选择。植酸酶分解植酸分子，在不利条件下优化必需矿物质的吸收，提高生产性能和蛋品质。具体而言，建议使用1500 FTU的植酸酶，因为它不仅能降低热应激的影响，还能增加蛋壳厚度和钙的吸收。在此背景下，本文献综述旨在撰写一份文件，证明植酸酶对植酸分子水解、日本鹌鹑钙的可利用性以及热应激影响的有益作用。
