Specific inhibition of Streptococcus bovis by endolysin LyJH307 supplementation shifts the rumen microbiota and metabolic pathways related to carbohydrate metabolism
BackgroundEndolysins, the bacteriophage-originated peptidoglycan hydrolases, are a promising replacement for antibiotics due to immediate lytic...

Hydrogen and formate production and utilisation in the rumen and the human colon
Molecular hydrogen (H 2 ) and formate (HCOO − ) are metabolic end products of many primary fermenters in the mammalian gut. Both play a vital role in...

Reprocessing of side-streams towards obtaining valuable bacterial metabolites
AbstractEvery year, all over the world, the industry generates huge amounts of residues. Side-streams are most often used as feed, landfilled,...

Replacing ground Rhodes grass hay with soyhulls in the pelleted diet: effects on ingestive behavior, nutrient digestibility, blood metabolites, growth performance, and economic viability of intensive fattening Lohi lambs
This study aimed to evaluate the effects of replacing soyhulls (SH) for ground Rhodes grass hay (RGH) in a pelleted diet on ingestive behavior,...

The effects of feeding chickpea grains on the lactating performance and blood metabolites of ewes
An experiment was conducted to see how replacing soybean meal with chickpea grains (CHPE) affected the performance, milk production, digestibility,...

Modes of genetic adaptations underlying functional innovations in the rumen
The rumen is the hallmark organ of ruminants and hosts a diverse ecosystem of microorganisms that facilitates efficient digestion of plant fibers. We...

Host and altitude factors affect rumen bacteria in cattle
There are many kinds of microorganisms in the gastrointestinal tract of mammals, some of which are closely related to the host. Rumen microorganisms...

Transcriptomic analysis reveals the molecular mechanisms of rumen wall morphological and functional development induced by different solid diet introduction in a lamb model
BackgroundThis study aimed to elucidate the molecular mechanisms of solid diet introduction initiating the cellular growth and maturation of rumen...

Effects of dietary rumen–protected Lys levels on rumen fermentation and bacterial community composition in Holstein heifers
This study aimed to evaluate the effects of partial reducing rumen-protected Lys (RPLys) on rumen fermentation and microbial composition in heifers....

Effect of feeding corn silage on semen quality and spermatogenesis of bulls
Bovine reproduction, including male fertility traits like semen quality, are influenced by a variety of different factors like breed, nutrition,...

Effects of using siris (Albizia lebbeck) foliage in the diet of fattening lambs on nutrient digestibility, blood and rumen parameters, growth performance, and meat quality characteristics
This study aimed to investigate the effect of substitution of siris foliage with alfalfa forage in the diet of fattening lambs on digestibility,...

Rumen fermentation and metabolic profile of rams fed with diets amended cottonseed cake
The aim of the study was to evaluate the addition of increasing cottonseed cake contents in the diet. The diets were composed of corn silage (500 g kg

Effects of king grass and sugarcane top in the absence or presence of exogenous enzymes on the growth performance and rumen microbiota diversity of goats
In the present study, the feasibility of sugarcane top (ST) application in the goat’s diet was evaluated. A total of 20 goats were randomly divided...

Plasmid-encoded toxin defence mediates mutualistic microbial interactions
Gut environments harbour dense microbial ecosystems in which plasmids are widely distributed. Plasmids facilitate the exchange of genetic material...

Interference of dietary polyphenols with potentially toxic amino acid metabolites derived from the colonic microbiota
Each day, varying amounts of undigested or partially digested proteins reach the colon where they are metabolized by the microbiota, resulting in the...

Influence of chitosan sources on intake, digestibility, rumen fermentation, and milk production in tropical lactating dairy cows
The aim of study was to compare the influence of chitosan sources (commercial chitosan vs chitosan extract) on rumen fermentation, methane (CH 4 )...

Dietary selection of metabolically distinct microorganisms drives hydrogen metabolism in ruminants
Ruminants are important for global food security but emit the greenhouse gas methane. Rumen microorganisms break down complex carbohydrates to...

Effect of castration timing and weaning strategy on the taxonomic and functional profile of ruminal bacteria and archaea of beef calves
BackgroundBeef cattle experience several management challenges across their lifecycle. Castration and weaning, two major interventions in the early...

Exploration of the effects of altitude change on bacteria and fungi in the rumen of yak (Bos grunniens)
The yak ( Bos grunniens ) is a ruminant animal with strong regional adaptability. However, little is known about the adaptation of the rumen microbial...

Could natural phytochemicals be used to reduce nitrogen excretion and excreta-derived N2O emissions from ruminants?
Ruminants play a critical role in our food system by converting plant biomass that humans cannot or choose not to consume into edible high-quality...
