The aim of this study was to compare between the crossbred and local chicken population based on its egg production performance. The animals used was 104 crossbred hen (F1 offspring of Merawang rooster x KUB hen) and 57 KUB hen (D = 33 hen, E = 24 hen). The F1 crossbred differentiated into four types: BS1, BS2, BS3, and BS4. Egg production indicator such as egg number, production rate, and egg weight were observed for 12 weeks (20 - 32 weeks old). The hen kept in individual battery cage and given the similar environment. The data were then analyzed using one-way ANOVA. As a result, there were a different egg performance between the crossbred (BS1, BS2, BS3, and BS4) and purebred (KUB D and KUB E). The crossbred had lower egg number, production rate, and egg weight than the KUB's. The KUB E had the highest production rate (47,22 ± 2,59%) and egg number (39,67 ± 2,17 egg/hen). Meanwhile, the KUB D had the highest egg weight (48.69 ± 2.72 g). In the crossbred group, the BS4 had the lowest number of eggs (20.62 ± 4.25 egg/hen), production rate (24.54 ± 5.06%), and egg weight (41.33 ± 0.86 g). The egg weight of BS5 (43,96 ± 0,44 g) was higher than the KUB E (43,14 ± 0,44 g). Among the crossbred there were no significant different performance (p < 0.05). These findings can be used as a reference for the selection of crossbred chicken variants to be developed.
