This program focuses on optimizing the genetic and environmental influences on the broiler chicken production continuum from commercial pureline genotypes, through parent stock production, incubation, broiler growth and meat yield dynamics. The approach employed is to characterize commercial products in terms of reproductive fitness (egg production, egg quality, feed efficiency), incubation physiology (residual yolk utilization and chick quality), broiler chicken growth rate, feed efficiency, breast muscle yield, muscle biology, carcass composition) and ultimately link the biology of the bird to commercially valuable traits in the whole bird, and further processed. Commercial breeding companies benefit through our physiological approaches used to identify selection criteria, based on intensive individual bird characterization. The program directly aids the Canadian broiler chicken supply chain by providing decision support to the hatching egg, broiler, and meat processing industries.

该计划的重点是优化遗传和环境对肉鸡生产连续性的影响，从商业纯系基因型，通过亲本生产，孵化，肉鸡生长和产肉动态。所采用的方法是从生殖适应性（产蛋量、蛋质量、饲料效率）、孵化生理学（残留蛋黄利用率和雏鸡质量）、肉鸡生长速度、饲料效率、胸肌产量、肌肉生物学、胴体组成等方面对商业产品进行表征，并最终将禽类生物学与整只禽类的商业价值性状联系起来，并进行进一步加工。商业育种公司受益于我们的生理学方法，用于确定选择标准，基于密集的个别鸟类特征。 该计划通过为孵化鸡蛋，肉鸡和肉类加工行业提供决策支持，直接帮助加拿大肉鸡供应链。
