Popis:	The experiment was conducted to evaluate the effect of breed, diet, and level of feed supplementation on growth performance, feed conversion ratio, and survivability of Sasso and Kuroiler chicken. The study was conducted in two separate phases, i.e., the starter phase (0-6 weeks of age) and grower phase (6-20 weeks of age). One thousand sixty-day-old Sasso and Kuroiler chicks were raised until 6 weeks under intensive management system with three dietary treatments. At the age of 6 weeks, a total of 960 birds (480 Sasso and 480 Kuroiler) were randomly selected from each treatment diet and assigned to four feed supplementation levels, i.e., 25%, 50%, 75%, and 100% with two replicates each having 20 birds. Beginning week 7, birds were allowed to semi-scavenge from 6:00 am in the morning to 6:00 pm in the evening with free access to open grass area of 1 bird/4 m
