📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の畜産分野では、メタン削減の遺伝的改良はまだ初期段階だが、Scope3排出削減やサステナビリティ報告の観点から、オーストラリアの取り組みは参考になる。特に、サプライチェーン排出量の削減要求が強まる中、畜産事業者にとって遺伝的改良は長期的な対策として注目される。
In the global GX context
This paper contributes to global discourse on agricultural GHG mitigation by detailing a pathway for genetic improvement in livestock. It offers insights for countries developing sustainability indexes and highlights the need for international collaboration in phenotyping, relevant to global efforts to reduce Scope 3 emissions in agriculture.

📄 Abstract（原文）
The Australian beef and sheep industries can play a small but important role in helping achieve global emissions targets. Genetic selection of cattle and sheep that emit less methane is an opportunity to make permanent and cumulative change and breeders are demonstrating growing interest for methane breeding values. However, the number and complexity of methane traits is causing confusion at the commercial level and needs clear communication guidelines. Clear guidance on which trait or traits should be adopted by industry is needed. The current selection index software (BreedObject and SheepObject) used by industry already has the functionality to select for methane predicted from other traits already included in the index, and once genomic breeding values for methane are available, they too can be included. For breeding values of measured methane to be published with a suitable prediction accuracy, large-scale phenotyping is required, and there are several ongoing projects within Australia that will help achieve that goal. This can be achieved sooner and with higher accuracies if phenotyping methods are improved for scalability for recording on commercial properties. International collaboration and alternative funding sources are likely to be the fastest path to achieving the rapid increase in phenotyping required to improve prediction accuracy and estimate currently unknown genetic correlations. This paper includes outcomes from a stakeholder workshop, detailing the philosophy for why methane should be selected for and the different methods that could be envisaged to reduce methane by genetic selection, the industry demands, the various methane trait definitions, a review of the fundamental research already completed, the tools already developed for implementing methane in selection indexes, ongoing Australian projects for large scale methane phenotyping, and the recommendations for the path forward to sustainability indexes in Australian beef and sheep.
