• Nutritive framework shows vitamins, minerals, and novel nutritional factors shaping growth, reproduction, and skeletal health, with Vitamin G linked to reproduction [2], phosphorus and protein balance driving bone integrity and rickets/perosis [7][9], and broader nutrition research highlighting relative protein efficiency and nutrient interactions [16][19][3][5][10].

• Environmental and management conditions drive egg production and egg quality, spanning seasonal effects on growth and feed use in turkey production [1], temperature effects on egg size [8], egg shelf-life and deterioration in storage [12], and post-collection handling's impact on keeping quality [18], plus strategies to secure earlier production through stimulated egg production [20].

• Bone health and skeletal disorders in poultry cluster around mineral nutrition and vitamins; perosis and rickets risk with phosphate and Vitamin G interactions, with phosphorus requirements [7], ground phosphate rock effects on growth/egg production [9], vitamin G role in reproduction [4], and nutrition-focused studies on rickets and bone metabolism [3][10][5].

• Growth physiology and systemic biology frame poultry development via body composition and normal growth trajectories, underpinned by measurements of hen body fats [6], normal growth under standard conditions [15], and blood physiology insights [17].
