Effects of dietary forage and calf starter on ruminal pH and transcriptomic adaptation of the rumen epithelium in Holstein calves during the weaning transition

Project description:We assessed the transcriptomic adaptation of the calf rumen epithelium to changes in ruminal pH caused by feeding calf starter with and without forage during weaning transition. The calves were divided into a gorage provision group (HAY group, n = 3) and forage non-provision group (CON group, n = 4) 3 weeks after weaning.

Systematic microRNAome profiling reveals the roles of microRNAs in milk protein metabolism and quality: insights on low-quality forage utilization

Project description:In this study, we investigated the molecular regulatory mechanisms of milk protein production in dairy cows by studying the miRNAomes of five key metabolic tissues involved in protein synthesis and metabolism from dairy cows fed high- and low-quality diets. In total, 340, 338, 337, 330, and 328 miRNAs were expressed in the rumen, duodenum, jejunum, liver, and mammary gland tissues, respectively. Some miRNAs were highly correlated with feed and nitrogen efficiency, with target genes involved in transportation and phosphorylation of amino acid (AA). Additionally, low-quality forage diets (corn stover and rice straw) influenced the expression of feed and nitrogen efficiency-associated miRNAs such as miR-99b in rumen, miR-2336 in duodenum, miR-652 in jejunum, miR-1 in liver, and miR-181a in mammary gland. Ruminal miR-21-3p and liver miR-2285f were predicted to regulate AA transportation by targeting ATP1A2 and SLC7A8, respectively. Furthermore, bovine-specific miRNAs regulated the proliferation and morphology of rumen epithelium, as well as the metabolism of liver lipids and branched-chain AAs, revealing bovine-specific mechanisms. Our results suggest that miRNAs expressed in these five tissues play roles in regulating transportation of AA for downstream milk production, which is an important mechanism that may be associated with low milk protein under lowquality forage feed.

The effects of a probiotic yeast on the bacterial diversity and population structure in the rumen of cattle.

Project description:SARST-V1 method was used to asses the effect of live yeast on the microbial population of the rumen of cows fed an acidogenic diet 3 cows were used in 3 by 3 latin-square design with 3 periods. In each period animals received either 0.5g/d of yeast, 5g/d of yeast or none. Rumen microbiota was analysed using the SARST-V1 method for each period.

The metabolic influence of the core ciliate Entodinium caudatum within the rumen microbiome

Project description:Protozoa comprise a major fraction of the microbial biomass in the rumen microbiome, of which the genera Entodinium has been consistently observed to be dominant across a diverse genetic and geographical range of ruminant hosts. Despite the apparent core role that species such as Entodinium caudatum exert, their greater biological and metabolic contributions to rumen function remain largely undescribed. Here, we have leveraged (meta)genome-centric metaproteome datasets from rumen fluid samples originating from both cows and goats fed contrasting diets, to detail the specific metabolic niches that E. caudatum occupies in the context of its bacterial and archaeal co-habitants. Initial proteome estimations via total protein counts and label free quantification highlight that E. caudatum populations comprise an extensive fraction of the total rumen metaproteome. Our analysis also suggested increased microbial predation and volatile fatty acid metabolism by E. caudatum to occur in high methane emitting animals, although with no apparent direct metabolic link to methanogenesis. Despite E. caudatum having a well-established reputation of digesting starch, it was unexpectedly less active in low methane emitting animals fed high starch diets, which were instead dominated by propionate/succinate-producing bacterial populations suspected of being resistant to predation. Collectively, our results illuminate the substantial metabolic influence under-explored eukaryotic populations have in the rumen, with greater implications towards both digestion and methane metabolism.
