摘要

该分析的数据表明,同时选择平均日增重和剩余采食量(RFI)可以识别出在不影响生长和母体epd的情况下提高生育力和寿命的肉牛。随着牛肉行业继续关注可持续性,从而提高效率,确定适合这种模式的商业种畜将势在必行。

Effects of Concurrent Selection for Residual Feed Intake and Average Daily Gain on Fertility and Longevity in Black Angus Beef Females
Data from this analysis suggest that concurrent selection for both average daily gain and residual feed intake (RFI) may identify beef heifers that have improved fertility and longevity without impacting growth and maternal EPDs. As the beef industry continues to focus on sustainability, and thus efficiency, identification of commercial breeding stock that fit this mold will be imperative.
