dc.description.abstract [EN] Objective: This study aimed to estimate the genetic parameters and genetic correlations for related feed efficiency, growth, and carcass traits in Hanwoo cattle. Methods: Phenotypic data from 15,279 animals born between 1989 and 2015 were con & shy; sidered. The related feed efficiency traits considered were Kleiber ratio (KR) and relative growth rate (RGR). Carcass traits analyzed were backfat thickness (BT), carcass weight, eye muscle area, and marbling score. Growth traits were assessed by the average daily gain (ADG), metabolic body weight (MBW) at mid & shy;test age from 6 to 24 months, and yearling weight (YW). Variance and covariance components were estimated using res & shy; tricted maximum likelihood using nine multi & shy;trait animal models. Results: The heritability estimates for related feed efficiency (0.28 +/- 0.04 for KR and RGR) and growth traits (0.26 +/- 0.02 to 0.33 +/- 0.04) were moderate, but the carcass traits tended to be higher (0.38 +/- 0.04 to 0.61 +/- 0.06). The related feed efficiency traits were positively gene & shy; tically correlated with all the carcass traits (0.37 +/- 0.09 to 0.47 +/- 0.07 for KR, and 0.14 +/- 0.09 to 0.37 +/- 0.09 for RGR), except for BT, which showed null to weak correlation. Conversely, the genetic correlations of RGR with MBW (-0.36 +/- 0.08) and YW (-0.30 +/- 0.08) were negative, and those of KR with MBW and YW were close to zero, whereas the genetic correlations of ADG with RGR (0.40 +/- 0.08) and KR (0.70 +/- 0.05) were positive and relatively moderate to high. The genetic (0.92 +/- 0.02) correlations between KR and RGR were very high. Conclusion: Sufficient genetic variability and heritability were observed for traits of interest. Moreover, the inclusion of KR and/or RGR in Hanwoo cattle breeding programs could improve the feed efficiency without producing any unfavorable effects on the carcass traits. es_ES
