Two experiments were conducted to study the effect of supplemental 100 g/day live Bacillus cultures (2 × 1011 cell subtilis and licheniformis) on rumen fermentation as well milk yield composition in Chinese Holstein cows. In experiment 1, investigating 3 10 cows, protein increased by using B. licheniformis (p < 0.05) comparison with an unsupplemented group group. Body weight was not significantly affected culture supplementation > 0.05). Percentage fat lactose different between treatments...
Abstract Background Providing high-quality roughage is crucial for improvement of ruminant production because it an essential component their feed. Our previous study showed that feeding bio-fermented rice straw (BF) improved the feed intake and weight gain sheep. However, remains unclear why BF to sheep increased gain. Therefore, purposes this research were investigate how rumen microbiota serum metabolome are dynamically changing after BF, as well changes influence intake, digestibility,...
Abstract Background Coumarins are toxic phytochemicals found in a variety of plants and known to limit microbial degradation interfere with nutrient cycling. While the coumarins by fungi has been studied an environmental context, little is about their gastrointestinal system herbivores after ingestion. Results In this study, we investigated vitro fermentation enrichment, transcriptome sequencing, high-resolution mass spectrometry evaluate ability rumen anaerobic degrade coumarins. The...
The study investigates the effects of Mongolian plants on reducing methane emissions, fermentation parameters, and microbial communities in grazing systems. Initially, various were screened to identify those that effectively reduced production vitro. most effective plant was selected for extraction its active components, resulting a solid extract with quantified concentration bioactive compounds. Extracts 0, 1.0, 2.0, 3.0, 4.0, 5.0% DM added, respectively, then subjected vitro rumen trials...
Abstract Background The nutrient availability of roughages could affect the dietary utilization efficiency ruminants even in isocaloric and isonitrogenous diets. Here, we analyzed bacterial composition their metabolic pathways gastrointestinal tracts (GITs) Hu sheep fed with wheat straw (WS) instead alfalfa (AL) diets, trying to explore reasons from perspective GITs network structure changes. Results We employed 16S rRNA gene sequencing combination Kruskal–Wallis test, Spearman correlation...
Bio-fermentation technology has been successfully developed for ensiling rice straw; however, its effects on the particle-attached microbial community remains unknown. Therefore, straw (RS) and bio-fermented (BFRS) were used as substrates in vitro rumen fermentation to investigate effect of bio-fermentation community, well their gas methane production, products, fiber degradation. Our results have shown that total degradation, products significantly higher (p < 0.05) BFRS than RS, while...
Phytosterols are natural steroids in plants, possessing bioactivities that could modify gut microbes. This experiment aimed to evaluate the effects of feeding phytosterols on community structures and metabolic functions rumen microbiota perinatal cows. Perinatal cows were supplied with 0 mg (control) or 200 (treatment) per day. Multiomic analyses used analyze microbiota. Results showed dietary increased copy number total ruminal bacteria, concentration microbial crude protein, molar...
This study aimed to investigate the changes in blood metabolic profiles of grazing yaks during cold season reveal their physiological status and seek nutrients needed be supplemented. Six castrated (3 years old) with 166.8 kg (standard deviation = 5.3) liveweight grazed Qinghai-Tibetan Plateau were used as experimental animals without supplementary feeding. Blood samples each animal collected October December 2015, March 2016 for analysis serum biochemicals metabolome. Results showed indices...
To efficiently use lignocellulosic materials in ruminants, it is crucial to explore effective enzymes, especially bifunctional enzymes. In this study, a novel stable cellulase-xylanase protein from buffalo rumen metagenome was expressed and characterized, CelXyn2. The enzyme displayed optimal activity at pH 6.0 45 °C. residual endoglucanase xylanase activities were 90.6% 86.4% after 60-min pre-incubation 55 Hydrolysis of rice straw, wheat sheepgrass sugar beet pulp by CelXyn2 showed its...
This study aims to obtain anaerobic fungi from the rumen and fecal samples investigates their potential for lignocellulosic bioconversion. Multiple strains were isolated contents (CR1–CR21) (CF1–CF10) of Bactrian camel using Hungate roll tube technique. After screening fiber degradability, ( Oontomyces sp. CR2) feces Piromyces CF9) compared with Pecoramyces F1 (earlier goat rumen, having high CAZymes GHs) various fermentation digestion parameters. The cultures fermented different substrates...
Objective: Previous research reported that dietary addition with phytosterols improved the energy utilisation of rumen microbiome, suggesting its potential to alleviate negative balance perinatal cows. This experiment aimed explore effects feeding on metabolic status cows through plasma metabolomics and faecal bacteria metabolism.Methods: Ten Holstein (multiparous, 2 parities) a similar calving date were selected four weeks before calving. After 7 days for adaptation, allocated two groups (n...

Abstract The objective of this study was to determine the effect natural co-culture anaerobic fungi and methanogens on methane production lignocellulosic degradation waste from rice, corn sugarcane. Hu sheep rumen digesta used develop a fungus methanogen. substrates in were rice straw (RS), rich husk (RH), stover (CS), cobs (CC), sugarcane baggage (SB). Production total gas methane, utilization rates reducing sugar, glucose, xylose, activity CMCase xylanase highest ( P < 0.05) CC,...
