After 10 weeks of age, pullets correctly regulate their energy intake according to the energy level of
the diet in both hot and temperate climates. Under consumption during that period is often the result
of a poor grit size. The objective is to develop the pullet's ability to eat feed, so that it can increase its
consumption by approximately 40% in the first few weeks of lay.
During the period 10 - 17 weeks, it is important to develop the digestive system by using diets with an
energy concentration less than or equal to that of the layer's diet.
