Abstract

The microbial community of cattle rumen (archaea) are the key players in methane emissions. Methane pollutes the atmosphere and leads to the loss of feed energy. The aim of this study was to comparatively investigate the cattle microbiota, with a particular focus on archaea, in relation to the type of housing: pasture versus stall. A 16S metabarcoding analysis of the intestinal contents of cattle was carried out. Аlpha - diversity of grazing animals showed to be higher compared to animals in the stall period (p=0.002). Beta - diversity confirmed a difference in methanogens and microbiota between animals kept on pasture and those in a stall. Differential abundance analysis showed that the relative abundance of the Methanobacteriacea family in animals in the pasture period was significantly higher compared to animals in the stall period (FDR p = 0.00122). In conclusion, this study demonstrates that the concentration of methanogens in the fecal contents of animals during pasture period was higher than that in animals during the stall period. We recommend feeding grazing animals with concentrates in the evening in order to mitigate methane emissions.

哈萨克牛牧场和棚舍相关甲烷微生物群的比较分析

牛瘤胃中的微生物群落（古细菌）是甲烷排放的主要参与者。甲烷污染大气并导致饲料能量损失。本研究的目的是对牛的微生物群进行比较研究，重点是与饲养类型（牧场和牛棚）相关的古细菌。对牛的肠道内容物进行了 16S 代谢编码分析。结果表明，放牧动物的 α - 多样性高于圈养动物（p=0.002）。Beta - 多样性证实，放牧与圈养动物的甲烷菌和微生物群存在差异。丰度差异分析表明，在牧场饲养的动物中，甲烷杆菌科的相对丰度明显高于在畜栏饲养的动物（FDR p = 0.00122）。总之，本研究表明，放牧期动物粪便内容物中甲烷菌的浓度高于滞育期动物。我们建议在傍晚用精料饲喂放牧动物，以减少甲烷排放。

期刊介绍： The journal was created as the Croce Azzurra in 1950. A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy. The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
