This study aims to determine the effect of using cricket flour (Gryllus sp) in the diet on the number, duration, and frequency of crowing crowning of balenggek cocks for 12-24 weeks. This study used 48 male balenggek crowing cocks which were given additional cricket flour diets. The completely randomized design (CRD), with 4 treatments, was used as the experimental design in this research. The treatments were: PO (no cricket flour), Pl (used cricket flour 2%), P2 (used cricket flour 4%), and P3 (used cricket flour 6%). Each treatment was repeated 4 times and each replication consisted of 3 male kokok balenggek cocks. The variables measured in this study were the number of crowings, duration, and frequency of crowing of kokok balenggek cocks at 12-24 weeks of age. The results showed that the addition of cricket flour in the ration had a significantly different effect (P<0.05) on the number of crows and the duration of crowing, and a very significant effect (P<0.01) on the crowing frequency of balenggek cocks at the age of 12- 24 weeks with the best number of crowings, duration, and frequency of crowing was in P3 (was used of 6% cricket flour)
