Broiler chickens were fed diets varying in their energy-to-protein (E:P) ratio, and then slaughtered at diflerent ages. From one to jive weeks of age, the chickens were fed a starter diet, which rangedfrom 120 to I70 Kcal per % protein, and thereafier thejnisher diets rangedfrom 140 to 190 Kcalper % protein, respectively.l'he highest relative taste preference of the meat from males was found when the starter dietary E:P ratio was approximately 136, and decreased sharply when it was 150 or more. l'his preference was independent of the age at slaughter. l'he highest relative taste preference of the meat from females was found when the age at slaughter was approximately 7.3 weeks. The dietary E:P ratio was of lesser significance, but with some preference toward the higher levels of the experimental range.
