📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の畜産分野におけるGHG排出削減（メタン対策）に関連する基礎研究として参考になる。ただし、日本のGX政策や開示制度（SSBJ等）への直接的な関連は薄く、畜産農家向けの実践的知見として位置づけられる。
In the global GX context
This research contributes to the global understanding of livestock-related methane emissions, which is relevant to agricultural GHG reduction targets. However, its direct applicability to corporate disclosure frameworks like TCFD or ISSB is limited, though it may inform sector-specific mitigation strategies.
👥 読者別の含意
🔬研究者:Provides insights into breed-specific gut microbiota interactions with methanogens, useful for developing targeted emission reduction strategies in livestock.
🏢実務担当者:Livestock producers may use breed-specific feeding strategies to potentially reduce methane emissions, though further validation is needed.
🏛政策担当者:May inform agricultural GHG mitigation policies by highlighting breed-specific factors, but broader implications are limited.
📄 Abstract（原文）
In order to identify the pedigreed features of the intestinal microbiota of Dorper and Romanovskaya sheep, which determine the release of greenhouse gases and the metabolic profile of blood in the Moscow region in 2025, an experiment was conducted on adult sheep of the Dorper (n=10) and Romanovskaya (n=10) breeds. The animals received a diet containing 1.7 kg of CB, 14.47 MJ of OE and 220 g of crude protein per head per day (1.6 kg of grain and grass hay + concentrate OK-80 400 g). At the end of the preliminary study period (30 days). The release of methane and carbon dioxide in animals was determined in vivo in respiratory chambers, blood samples were taken for biochemical and hematological analysis, and the contents of the rectum were assessed by real-time PCR using the Colonoflor-16 (premium) kit. The total bacterial mass was 11.20–11.23 log10 DNA copies/ml, dominated by Bacteroides spp. (8.83–8.93) and Bifidobacterium spp. (8.22–8.43). The breed factor did not significantly affect the abundance of most taxa and gas formation (p>0.05). Breed differences in the interaction of bacteria with methanogens have been established: the Romanov breed has a competitive strategy (negative correlation of Bacteroides spp . with methane per 1 kg of live weight, r=-0.677; total bacterial mass with daily methane, r=-0.585), in dorpers – cooperative (positive correlation of Bifidobacterium spp. with methane per 1 kg of consumed dry matter, r=+0.589). In dorpers, Escherichia coli positively correlated with the daily release of CO ₂ (r=+0.667, p<0.05) and with CO ₂ per 1 kg of dry matter (r=+0.787, p<0.05). In the Romanov breed, Bifidobacterium spp . positively correlated with albumins (r=+0.79, p<0.05) and negatively with globulins (r=-0.77, p<0.05) and triglycerides (r=-0.68, p<0.05). The results can be used to develop breed-specific animal feeding strategies.
