The treatments were conducted to evaluate the effect of dietary CP (17.5, 19, and 20.5%) and energy (2850-2950 kcal ME/kg) on slow-growing chickens using an ideal protein concept at a high altitude (3200 m). We used a total of 144 slow-growing chickens. The experiment lasted for eight weeks, a total of six treatments with three replicates each and eight chickens per replicate were used. Body Weight Gain (BWG) showed differences only in the growing chickens, for CP and the energy × CP interaction, the lowest BWG was at 17.5% CP (2850 kcal ME/kg) and 19.0% at 2950 kcal ME/kg (p}, journal = {American Journal of Animal and Veterinary Sciences}, publisher = {Science Publications} }
