Abstract

This study was conducted to compare the phenotypic performance and genetic merits in terms of weight at 12 months, carcass weight, eye muscle area, backfat thickness, marbling score and selection index of Hanwoo young bulls and proven bulls from the year 2004 to 2006. The data of 208 bulls used in this study were taken from the Nnational Hanwoo genetic evaluation coordinated by National Institute of Animal Science. Hanwoo young bulls were superior in the phenotypic performance of weight at 12 months, carcass weight, and eye muscle area showing significant differences from Hanwoo proven bulls in most comparisons. The backfat thickness of Hanwoo young bulls was significantly thicker higher than Hanwoo proven bulls in all comparisons (p < 0.05). Also, Hanwoo young bulls were not significantly different from Hanwoo proven bulls in the genetic merits of weight at 12 months, carcass weight, eye muscle area, backfat thickness, marbling score, and total genetic merits. Performance of Hanwoo young bulls were not significantly different from 1st class of Hanwoo proven bulls in all the traits studied except in eye muscle area.
