Most carcass and meat quality traits are moderate to highly heritable, indicating that they can be improved through selection. Genetic evaluation for these types of is performed using performance data obtained from commercial progeny testing evaluation. The farms available in large volume, however, some drawbacks have been observed. drawback the mainly due sorting animals based on live weight prior slaughter, this could lead bias genetic later measured such as traits. current study has two components address data. first component aimed estimate parameters Korean Hanwoo cattle a sample size industry-based records (n = 469,002). second describe impact into different contemporary groups an early trait then examine effect subsequently To demonstrate our objectives, we used real simulated was assess results showed slaughterhouses potential source useful improve beef performance. However, observed harvesting which leads This selection animal their body before arrival slaughterhouse. Overall, non-random allocation group biased estimated breeding value evaluation, severity increases when correlated.
