Estimation of equations for predicting the nutritional energy requirements of broiler breeders and laying hens


, : Estimation of equations for predicting the nutritional energy requirements of broiler breeders and laying hens. Revista da Sociedade Brasileira de Zootecnia 22(5): 723-731

Equations for predicting apparent and true metabolizable energy (AME and TME) requirements of breeding and laying hens were determined by the factorial method. AME and TME requirements for egg production based on energy value of the egg (1.538 kcal/g) and conversion efficiency (80%) were 1.92 and 2.05 kcal/g egg, respectively. Requirements for weight gain (WG) were 3.84 and 4.11 kcal/g.
