摘要： Studies on the rumen microbiota for cattle production and greenhouse gases mitigation are fragmented, and protozoa have been overlooked when evaluating the contribution of microorganisms to cattle sustainability. The present study meta-analyzed the contribution of three rumen microbial group (protozoa, bacteria and archaea) to body weight gain, milk yield and to the reduction of methane and ammonia productions. Rumen protozoa, bacteria and archaea were assigned to 69 treatments collected from 4394 papers screened to retain 27 articles. Entodinium, the most predominant rumen protozoa, increased by 24 % at lower (<663 kg) cattle body weight and were maintained at higher body weight (>= 663 kg). Their abundance increased by 63 % at lower milk yield (<30 kg/d) and decreased by 36 % in higher milk producing cattle (>= 30 kg/d); this suggests that higher Entodinium abundance increased their predation on feed-degrading bacteria, substantially decreasing nutrient bioavailability for higher cattle performance. Entodinium abundance decreased by 74 % when CH4 decreased from 400-650 to 200-400 g/d, associated with high (>= 100 mg/L) NH3 production. Prevotella was a core bacterial group linked to methane reduction while also playing a key role in nutrient metabolism. Among the archaeal groups, Methanosphaera abundances decreased with increasing CH4 content. Entodinium is the main rumen protozoa genera that could effectively serve as biomarker for reduction of methane production whilst increasing cattle body weight and milk yield. This study shed light on the rumen microbial drivers of sustainable and climate-smart cattle production.
