effects of diet formulation based on metabolizable energy (amen and tmen) total and digestible amino acid of feed and requirements on broiler breeder performance

a study was conducted to determine the effects of diet formulation on arian broiler breeder performance in their 50 to 64 wks of age. one hundred and sixty eight female and 24 male breeders were employed in 8 treatments of 3 replicates (7 females plus a male) in a completely randomized design (a factorial experience of 2 × 2 × 2). eight experimental diets were formulated based on three factors, the first factor including, two levels of apparent and true metabolisable energy corrected for nitrogen (amen and tmen), the second factor being:, two levels of total amino acids (taaf) and digestible (daaf) of feed, the third factor was included two levels of broiler breeder hens requirements as based on total amino acids (taar) and digestible ones (daar). the results indicated that egg weight was significant difference on the main effects of energy and the main effects of amino acids of feed and requirements no significant (p
