Knowing how energy intake is partitioned between maintenance, growth and egg production (EP) of birds makes it possible to structure models and recommend energy intakes based on differences in the BW, weight gain (WG) and EP on commercial quail farms. This research was a dose-response study to re-evaluate the energy partition for Japanese quails in the EP phase, based on the dilution technique to modify the retained energy (RE) of the birds. A total of 300 VICAMI® Japanese quail, housed in climatic chambers, were used from 16 weeks of age, with averages for BW of 185 g and EP of 78%, for 10 weeks. To modify the RE in the bird’s body, a qualitative dilution of dietary energy was used. Ten treatments (metabolisable energy levels) were distributed in completely randomised units, with six replicates of five quails per experimental unit. Metabolisable energy intake (MEI), egg mass (EM) and RE were expressed in kJ/kg0.67. The utilisation efficiency (kt) was estimated from the relationship between RE and MEI. The metabolisable energy for maintenance was given by RE = 0. The net energy requirement for WG was obtained from the relationship between RE in the BW as a function of the BW. The utilisation efficiency for EP (ko) was obtained from the relationship between EM and RE corrected MEI for maintenance and WG. Based on these efficiencies, the requirements for WG and EM were calculated. The energy intake by Japanese quails was partitioned according to the model: MEI = 569.8 × BW0.67 + 22 × WG + 13 × EM. The current study provides procedures and methods designed for quails as well as a simple and flexible model that can be quickly adopted by technicians and poultry companies.

了解家禽的能量摄入如何在养护，生长和产蛋（EP）之间进行分配，可以构建模型并根据商业鹌鹑养殖场的体重，体重增加（WG）和EP的差异推荐能量摄入。这项研究是一项剂量反应研究，基于稀释技术修改了禽类的保留能量（RE），从而重新评估了日本鹌鹑在EP期的能量分配。共有300 VICAMI的®从16周龄开始使用日本鹌鹑，它们存放在气候室中，平均体重为185 g，EP为78％，持续10周。为了改变鸟类体内的稀土元素，使用了定性稀释的饮食能量。十种治疗（可代谢的能级）以完全随机的单位分配，每个实验单位有五个鹌鹑的六次重复。代谢能摄入量（MEI），鸡蛋质量（EM）和RE以kJ / kg 0.67表示。利用率（k t）是根据RE和MEI之间的关系估算的。维持的可代谢能量由RE = 0给出。WG的净能量需求是通过BW中RE与BW之间的关系得出的。EP（k o）的利用效率是从EM和经RE校正的维护保养维护工程师（EI）和工作组（WG）之间的关系得出的。基于这些效率，计算出WG和EM的要求。日本鹌鹑的能量摄入根据模型进行了划分：MEI = 569.8×BW 0.67 + 22×​​WG + 13×EM。当前的研究提供了为鹌鹑设计的程序和方法，以及可以被技术人员和家禽公司迅速采用的简单灵活的模型。
