The aim of this project is to explore options for implementing a new approach to assess feed conversion efficiency (FCE) in UK beef cattle. The longer-term aim is to use the new approach to breed for cattle with high FCE. It is important to maximize FCE because feed is the largest production cost in beef production and breeding for high FCE is a good long-term strategy that has worked well in the pig and poultry industries. The traditional approach to breed for FCE has been to measure feed intake and weight gain over long periods of time, but this is expensive for beef cattle and so has only been implemented for a few breeds in other countries. The project is based on testing for a novel biomarker and we will explore the practicalities of implementing this method alongside other on-farm testing of beef cattle and use the results to define options for future sampling and testing protocols.

该项目的目的是探索实施一种新的方法来评估英国肉牛的饲料转化效率（FCE）的选择。长期目标是使用新方法培育高FCE的牛。最大化FCE非常重要，因为饲料是牛肉生产中最大的生产成本，而高FCE育种是一项良好的长期战略，在猪和家禽行业中效果良好。传统的FCE育种方法是在很长一段时间内测量采食量和体重增加，但这对肉牛来说很昂贵，因此在其他国家只对少数品种实施。该项目基于对一种新型生物标志物的测试，我们将探索实施这种方法以及其他肉牛农场测试的可行性，并使用结果来确定未来采样和测试方案的选择。
