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