摘要

过去的研究只研究了遗传面板评分和饲养场性能。本研究结合了遗传小组得分对小牛养殖的影响和先前估计的饲养场影响，以评估牛肉产业中不一致的经济激励的可能性。在大理石纹和柔嫩这两种胴体性状上遗传得分较高的犊牛，断奶体重较低，净收益较低。遗传性状与奶牛体型的相关性较小，且基本不显著。面板得分高一个单位对饲养场和小牛部门的影响总和为每头牛每年-2.83美元的大理石纹和-4.93美元的嫩度。

What is the Cow-Calf Economics of Genetic Panel Scores for Feedlot Traits?

Abstract Past research has only studied genetic panel scores and feedlot performance. This research combines impacts of genetic panel scores on a cow-calf operation with previously estimated feedlot impacts to evaluate the potential for misaligned economic incentives in the beef industry. Calves that were higher genetic scores for two carcass traits, marbling and tenderness, had lower weaning weights and lower net returns. Correlations between genetic traits and cow size were small and mostly insignificant. The sum of the effects on feedlot and cow-calf sectors of a one-unit higher panel score totaled $-2.83 per cow year for marbling and $-4.93 per cow year for tenderness.
