This study aims to evaluate the performance and estimate the heritability values of body weight and size in F2 offspring resulting from the cross of Merawang chickens and Kampung Unggul Balitbangtan chickens during the grower phase. The study was conducted in Semanu, Gunungkidul, Yogyakarta from November 2023 to January 2024. The study utilized a total of 224 F2 crossbred chickens from the Merawang Sembawa and KUB Jatinom breeds (A), 219 F2 crossbred chickens from the Merawang Bangka and KUB Jatinom breeds (B), 66 F2 crossbred chickens from the Merawang Sembawa and KUB Bogor breeds (C), and 155 F2 crossbred chickens from the Merawang Bangka and KUB Bogor breeds (D). The acquired data encompasses performance of body weight and size, including chest width, shank length, chest circumference, and wing length. The performance data acquired were examined using a one-way ANOVA and the Duncan test. The heritability value is estimated using the method of half-sibling correlation and examined using a one-way ANOVA. The analytical results demonstrate that the performance of body weight and size is superior in crossbreeding pattern D when compared to patterns A, B, and C. The estimated heritability values of body weight and size in the crossbreeding patterns A, B, C, and D range from 0,12 to 0,98. According to the research, it can be concluded that body weight and size can be used to selection criteria due to the heritability of those criterias was moderate to high.
