The layer’s peak energy needs are most likely met at around 35 – 40 weeks of age, when daily egg mass output is maximized. However, the layer quite precisely adjusts its intake according to needs for energy, and so variable energy needs are accommodated by change in feed intake.
Most Leghorn strains will now commence egg production with feed intakes as low as 80 – 85 g per day, and it is difficult to formulate diets for such a small appetite. For brown-egg strains, initial feed intake will be around 92 – 95 g per day, so formulation is more easily accommodated. For all diets, maintaining the balance of all nutrients to energy is the most important consideration during formulation.

Diet formulation and feeding management are now critical aspects of growing pullets to the onset of sexual maturity. Age at maturity is advancing by around one day per year, and this is especially true for many strains of brown egg pullets. The traditional concern with early maturity has been too many small eggs. There seems little doubt that bodyweight and perhaps body composition at this time are the major factors influencing egg size both at maturity and throughout the remainder of the laying period. Bodyweight is the main factor controlling early egg size.
One of the most important concepts today in pullet feeding is to schedule diets according to bodyweight and condition of the flock rather than according to age. For example, traditional systems involve feeding starter diets for about six weeks, followed by grower and then developer diets.
