Genus is providing targeted genetic solutions for farmers to create more value for the beef supply chain. Internal trials have demonstrated the superiority of targeted genetics for increasing supply chain profitability relative to traditional practices. Beef calves that are more efficient will reduce carbon footprint are increasingly demanded by supply chain stakeholders to achieve UK carbon reduction targets. Genus and SRUC have carried out ground-breaking research on beef cattle showing the potential of ruminal microbiome-driven breeding to mitigate methane emissions with an expected reduction of up to 17% per generation (Martínez-Álvaro et al., 2022) and improvement of feed conversion ratio by up to 15% per generation. A conservatively estimated 10% reduction in GHG emissions in Genus-influenced animals alone, for example, is a 337,000 metric tons reduction per year in the UK, which is permanent and increasing with ongoing genetic improvement.

Genus正在为农民提供有针对性的遗传解决方案，为牛肉供应链创造更多价值。内部试验已经证明，与传统做法相比，靶向遗传学在提高供应链盈利能力方面具有优势。供应链利益相关者越来越多地要求更高效的小牛犊减少碳足迹，以实现英国的碳减排目标。Genus和SRUC对肉牛进行了开创性的研究，显示了瘤胃微生物驱动的育种在减少甲烷排放方面的潜力，预计每代减少17%(Martínez-álvaro等人，2022年)，每代饲料转化率提高多达15%。例如，保守估计，仅受属影响的动物的温室气体排放量就减少了10%，在英国每年就减少了33.7万吨，这是永久性的，并且随着不断的遗传改进而增加。
