Abstract
The improvement and long term sustainability of local cattle genetics in Indonesia are essential to support national beef productivity. This study aimed to identify superior Ongole Crossbred (OC) bulls through an integrated evaluation of genetic potential, semen quality, and the reproductive performance of their male offspring. A total of 82 heads consisted of 38 OC bulls and their 44 male offspring were evaluated for morphometric traits (body weight and withers height) and semen quality parameters (motility, concentration, and viability). Genetic evaluation was performed using phenotypic selection combined with Most Probable Producing Ability (MPPA) analysis to predict the consistency of inherited traits. The results showed that two of four selected bulls exhibited the most favorable combination of growth traits and reproductive parameters. Both bulls produced semen with motility and viability exceeding breeding standards (>70%), with body weights above population average. Heritability (h²) values for semen traits ranged between 0.19 and 0.29, and repeatability (r) values were high (>0.49), indicating substantial genetic influence and stability of trait expression across ejaculate records. Among the 11 progeny that were selected, high performance of bulls had sperm motility, ranging from 45.0-87.3%; sperm concentration (899.1-2066.0 million/mL); viability (57.0-94.2 %). Repeatability (r), heritability (h²) and MPPA values of selected offspring for semen traits; motility (0.49; 0.20; 69.12); consentration (0.49; 0.29; 1101.16); viability (0.51; 0.19; 79.92); and body weight (0.50; 0.14; 509.10). Overall, bull A.219/1 showed the most optimal combination of genetic and reproductive characteristics, followed successively by bulls 12.12.34, 13.12.26, and 14.2.2.
