Background: Megasphaera elsdenii is an ecologically important rumen bacterium that metabolizes lactate and relieves acidosis (RA) induced by a high-grain-diet. Understanding the regulatory mechanisms of metabolism this species in RA conditions might contribute to developing dietary strategies alleviate acidosis. Methods: was co-cultured with four producers (Streptococcus bovis, Lactobacilli fermentum, Butyrivibrio fibrisolvens Selenomonas ruminantium) series substrate starch doses (1, 3 9...
As one of functional active amino acids, L-arginine holds a key position in immunity. However, the mechanism that arginine modulates cow mammary inflammatory response ruminant is unclear. Therefore, this study was conducted to investigate effects on and casein expression after challenging bovine epithelial cells (BMECs) with lipopolysaccharide (LPS). The were divided into four groups, stimulated or without LPS (10 μ g/mL) treated (100 for 12 h. concentration proinflammatory cytokines,...
The study objective was to investigate the effects of site delivering Saccharomyces cerevisiae fermentation product (SCFP) on ruminal pH and characteristics, extent feed digestion in digestive tract beef heifers fed high-grain diets. Examining postruminal SCFP is important for understanding potential use as an alternative current industry-standard antibiotics used cattle rations. Five (initial BW = 561 ± 11.7 kg) equipped with duodenal cannulas were a 5 × Latin square design 28-d periods,...
The objective of this study was to evaluate the effects supplementing diet finishing beef steers with active dried yeast (ADY) in ruminally protected and nonprotected forms on growth performance, carcass traits, immune response. Seventy-five individually-fed Angus (initial body weight (BW) ± SD, 448 8.4 kg) were assigned a randomized complete design 5 treatments: 1) control (no monensin, tylosin, or ADY), 2) antibiotics (ANT, 330 mg monensin + 110 tylosin·steer−1d−1), 3) ADY (1.5...
The colonization of microbes in the gut is key to establishing a healthy host-microbiome symbiosis for newborns. We longitudinally profiled microbiome model consisting 36 neonatal oxen from birth up 2 months postpartum and carried out microbial transplantation reshape their microbiome. Genomic reconstruction deeply sequenced fecal samples resulted total 3931 metagenomic-assembled genomes 472 representative species, which 184 were identified as new species when compared with existing...
ABSTRACT When ruminants are fed high-concentrate diets, Streptococcus bovis proliferates rapidly and produces lactate, potentially causing rumen acidosis. Understanding the regulatory mechanisms of metabolism this species might help in developing dietary strategies to alleviate S. strain S1 was newly isolated from ruminal fluid Saanen dairy goats then used examine effects glucose starch on bacterial gene regulation organic acid-producing pathway cultures at a pH 6.5. Glucose or added culture...
The objectives of this study were to assess the effects Saccharomyces cerevisiae fermentation products (SCFP; NaturSafe, SCFPns; and Original XPC, XPC; Diamond V) on growth performance, carcass traits, immune response, antimicrobial resistance in beef steers fed high-grain diets. Ninety Angus (initial body weight [BW], 533 ± 9.8 kg) assigned a randomized complete design with 6 treatments (n = 15/treatment): 1) control, 2) low (12 g SCFPns·steer-1·d-1), 3) medium (15 4) high SCFP (18 5)...
Abstract Background This study was conducted to evaluate the feed nutritional value of brewers’ spent grain (BSG) residue resulting from protease aided protein removal. The measured as nutrient content, gas production, digestibility and fermentation characteristics in batch culture. Results Protein extraction process decreased content crude but concentrated neutral detergent fibre (NDF) ferulic acid BSG residue. changes chemical composition varied with enzyme dosage. Digestibility dry matter...
The aim of this study was to investigate the effect low-protein diets supplemented with rumen-protected lysine (RPLys) and methionine (RPMet) on growth performance, rumen fermentation, blood biochemical parameters, nitrogen metabolism, gene expression related N metabolism in liver Holstein bulls. Thirty-six healthy disease-free bulls a similar body weight (BW) (424 ± 15 kg, 13 months old) were selected. According their BW, they randomly divided into three groups 12 each group completely...
Adequate energy supply is a crucial factor for maintaining the production performance in early lactating cows. Adding fatty acids to diets can improve supply, while effect could be related chain length and degree of saturation acids. This study was conducted evaluate different ratios palmitic acid (C16:0) oleic (cis-9 C18:1) on performance, nutrient digestibility, blood metabolites milk profile dairy Seventy-two multiparous Holstein cows (63.5 ± 2.61 d milk) blocked by parity (2.39 0.20),...
Cereal grains treated with organic acids were proved to increase ruminal resistant starch and can relieve the risk of acidosis. However, previous study mainly focussed on acid-treated barley, effects corn is still unknown. The objectives this evaluate whether feeding ground steeped in citric acid (CA) would affect pH fermentation patterns, milk production innate immunity responses dairy goats. Eight ruminally cannulated Saanen goats used a crossover designed experiment. Each experimental...
Enhancing the post-ruminal supply of arginine (Arg), a semi-essential amino acid (AA), elicits positive effects on milk production. Our objective was to determine Arg infusion production parameters and aspects nitrogen (N) absorption utilization in lactating dairy cows. Six Chinese Holstein cows similar body weight (508 ± 14 kg), condition score (3.0 0), parity (4.0 yield (30.6 1.8 kg) days (20 2 d) were randomly assigned 3 treatments replicated × Latin square design with 21 d for each...
Lycium barbarums are traditionally used as a homology of medicinal plants in China with potent role metabolism and immunomodulation. The current study was performed to explore the attenuation effect microbiota regulation barbarum polysaccharide (BLBP) on lipopolysaccharide (LPS)-induced intestine damage mice. A total 70 mice were randomly divided into five groups; negative control (GA), LPS (GB), both treated an equal volume normal saline, BLBP treatment groups GC (100 mg/kg), GD (200 GE...
Abstract Serum proteins are sensitive with diseases in dairy cows, and some of them could be used as biomarkers for fatty liver. This study aimed to explore serum liver cows. A total 28 early lactating cows were chosen from a commercial herds, samples collected determining concentration triacylglycerol ( TAG ), measuring fibroblast growth factor-21 FGF-21 adiponectin, Lipoprotein-associated phospholipase A2 LP-PLA2 hemoglobin Hb ). Dairy divided into (liver > 5%, wet weight) control group...
Abstract A metabolism study was conducted using 8 ruminal cannulated beef heifers to investigate the effects of a recombinant fibrolytic enzyme (RFE; xylanase XYL10C) selected specifically for forage-fed ruminants on pH, fermentation, nitrogen balance, and total tract digestibility heifers. The experiment cross-over design with 2 treatments periods. were basal diet containing 60% barley silage, 30% straw, 10% supplement (DM basis) without (control) or RFE. sprayed onto straw at rate 6.6 ×...

Abstract Domesticated herbivores are an important agricultural resource that play a critical role in global food security, particularly as they can adapt to varied environments, including marginal lands. An understanding of the molecular basis their biology would contribute better management and sustainable production. Thus, we conducted transcriptome sequencing 100 105 tissues from two females each seven species herbivore (cattle, sheep, goats, sika deer, horses, donkeys, rabbits) breeds...
