Under most practical feeding situat

Under most practical feeding situations, the energy level of the diet is the major factor influencing feed intake. Within the regulatory mechanisms described in the previous section is an inherent system that very precisely controls the bird’s ‘daily’ energy intake. As energy concentration of the diet increases, a bird eats less feed, while a reduction in diet energy level prompts an increase in intake. This mechanism applies to all types and ages of chicken and is very precise and accurate.
