Free-range chickens represent the most widely preferred poultry species among the Indonesian population, irrespective of age groups. In this study, 100 native chickens in the grower phase at 10 weeks of age were used. The experiment lasted for eight weeks and consisted of five dietary treatments, each with five replications, and each group contained four birds. The treatments were R0: 100% basal diet + 0% avocado seed flour, R1: 95% basal diet + 5% avocado seed flour, R2: 90% basal diet + 10% avocado seed flour, R3: 85% basal diet + 15% avocado seed flour, and R4: 80% basal diet + 20% avocado seed flour. During the study, data were collected on feed consumption, weight gain, feed conversion ratio, live weight, and carcass characteristics including breast percentage, thigh percentage, back percentage, and wing percentage. Data were analyzed by one-way variance (ANOVA). The results of the study showed no difference in all treatments compared to the R0 treatment (control). The conclusion is that avocado seed flour can be used as an alternative material for native chickens in the grower phase to replace commercial feed at a usage level of up to 20% without causing negative effects on meat quality.
