“…According to Guo et al. [ 25 ], the rumen microbiota of calves showed significant similarity to that of cows during the first 2 weeks of life. Specifically, the majority of the microbiota found in the rumen of calves was derived from that of mother cows.…”

Recent studies have reported that some rumen microbes are “heritable” (those have significant narrow sense heritability) and can significantly contribute to host phenotype variations. However, it is unknown if these heritable rumen bacteria can be passed to the next generation. In this study, the rumen bacteria from mother cows (sampled in 2016) and their offspring (sampled in 2019) were assessed to determine if vertical transmission occurred between the two generations. The analysis of relationship between host genotypes and heritable bacterial abundances showed that potential of five host genotypes can affect the relative abundances of two unclassified species level heritable bacteria (Pseudoscardovia, and p-251-o5). The G allele of BTB-01532239 and A allele of ARS-BFGL-NGS-8960 were associated with a higher relative abundance of p-251-o5. The A allele of BTB-00740910 and BovineHD1300021786, and G allele of BovineHD1900005868 were associated with a higher relative abundance of Pseudoscardovia. The mother-offspring comparison revealed that the heritable rumen bacteria had higher compositional similarity than nonheritable bacteria between two generations, and the predicted heritable microbial functions had higher stability than those from non-heritable bacteria. These findings suggest that a high stability exists in heritable rumen bacteria, which could be passed to the next generation in dairy cows.

“…This genus is unique in a way that it produces CH 4 through the reduction of methanol and methylamines, rather than H 2 and CO 2 [50]. Methanomassiliicoccus has been suggested as a potential target for inhibiting ruminal CH 4 emissions due to its ability to outcompete hydrogenotrophic methanogens [53]. Also, Methanospirillum, classified within the order Methanomicrobiales and the phylum Euryarchaeota, has been found in the rumen and feces of cattle and sheep [54].…”

“…Guo and colleagues characterized the archaeal community shared between the maternal rumen and milk in grazing yak calves. They identified two archaeal phyla and 11 different common archaeal genera [53]. The primary archaeal phyla found on the skin of the teat were Euryarchaeota (76.8%) and Thaumarchaeota (23.1%) with the dominant genera being Methanobrevibacter (61.7%) and Candidatus nitrocosmicus (12.5%).…”

Despite the extensive research conducted on ruminal methanogens and anti-methanogenic intervention strategies over the last 50 years, most of the currently researched enteric methane (CH4) abatement approaches have shown limited efficacy. This is largely because of the complex nature of animal production and the ruminal environment, host genetic variability of CH4 production, and an incomplete understanding of the role of the ruminal microbiome in enteric CH4 emissions. Recent sequencing-based studies suggest the presence of methanogenic archaea in extra-gastrointestinal tract tissues, including respiratory and reproductive tracts of cattle. While these sequencing data require further verification via culture-dependent methods, the consistent identification of methanogens with relatively greater frequency in the airway and urogenital tract of cattle, as well as increasing appreciation of the microbiome–gut–organ axis together highlight the potential interactions between ruminal and extra-gastrointestinal methanogenic communities. Thus, a traditional singular focus on ruminal methanogens may not be sufficient, and a holistic approach which takes into consideration of the transfer of methanogens between ruminal, extra-gastrointestinal, and environmental microbial communities is of necessity to develop more efficient and long-term ruminal CH4 mitigation strategies. In the present review, we provide a holistic survey of the methanogenic archaea present in different anatomical sites of cattle and discuss potential seeding sources of the ruminal methanogens.

Microbiota from mothers is an essential source of microbes in early-life rumen microbiota, but the contribution of microbiota from different maternal sites to the rumen microbiota establishment in neonates needs more data. To fill this gap, we collected samples from the mouth, teat skin, and rumen of lactating yaks and from the rumen of sucking calves concomitantly on seven occasions between days 7 and 180 after birth under grazing conditions. We observed that the eukaryotic communities clustered based on sample sites, except for the protozoal community in the teat skin, with negative correlations between fungal and protozoal diversities in the rumen of calves. Furthermore, fungi in the dam’s mouth, which is the greatest source of the calf’s rumen fungi, accounted for only 0.1%, and the contribution of the dam’s rumen to the calf’s rumen fungi decreased with age and even disappeared after day 60. In contrast, the average contribution of the dam’s rumen protozoa to the calf’s rumen protozoa was 3.7%, and the contributions from the dam’s teat skin (from 0.7 to 2.7%) and mouth (from 0.4 to 3.3%) increased with age. Thus, the divergence in dam-to-calf transmissibility between fungi and protozoa indicates that the foundation of these eukaryotic communities is shaped by different rules. This study provides the first measurements of the maternal contribution to the fungal and protozoal establishment in the rumen of sucking and grazing yak calves in early life, which could be beneficial for future microbiota manipulation in neonatal ruminants. Key points • Dam to calf transfer of rumen eukaryotes occurs from multiple body sites. • A minor proportion of rumen fungi in calves originated from maternal sites. • The inter-generation transmission between rumen fungi and protozoa differs.
