Summary: Subacute rumen acidosis may cause dysfunction of the intestinal barrier, which is not due to increased hindgut fermentation. It is possible that the plethora of harmful substances produced in the rumen during subacute rumen acidosis, such as ethanol, endotoxin, and amines, contribute to intestinal hyperpermeability. This study aimed to evaluate the effects of abomasal infusion of acidotic rumen fluid collected from donor cows on systemic inflammation, metabolism, and production in healthy recipient cows.

Summary: This study investigated the effects of supplementing medium-chain fatty acids (MCFAs) at a lower dose on productivity, nutrient digestibility, rumen fermentation, and rumen microbial profile of lactating dairy cows. The results suggest that MCFA supplementation had no significant effects on overall animal performance or total tract nutrient digestibility, but did decrease the daily pH range and bacterial richness in the rumen.

Summary: Astrocytes play a crucial role in responding to extracellular pH changes through the regulation of NBCe1, an acid-base transporter. The study found that mTOR-dependent and NBCe1-mediated astrocytic response to extracellular acidosis involves multiple molecular mechanisms, including serine residue phosphorylation at Ser(245) as a novel regulator of NBCe1 functional expression. The results suggest that context-dependent and mTOR-mediated multisite phosphorylation of serine residues of NBCe1 may be a potent mechanism contributing to astrocytes' response to acid/base challenges in pathophysiological conditions.

Summary: The study aimed to characterize the impact of diets with different starch and fiber sources on rumen VFA concentrations, rumen epithelial gene expression, and blood metabolite responses. Results showed that timothy hay had the greatest effect on shifts in VFA molar proportions and epithelial transporters, but did not demonstrate significant shifts in blood metabolite concentrations.

Summary: There is controversy over whether monensin provides equal or differential benefits in higher-energy, lower-roughage close-up diets compared to higher-roughage, lower-energy diets. This study aimed to determine the effects of different diets and monensin supplementation on the rumen. It was found that the addition of monensin affected liquid passage rate and volatile fatty acid concentrations differently.

Summary: Subacute rumen acidosis (SARA) is caused by highly fermentable carbohydrates in the diet, which lower pH and disrupt the microbial ecology of the rumen. Biochanin A (BCA) can counteract the pH, microbiological, and fermentative changes associated with SARA challenge.

Summary: Subacute ruminal acidosis (SARA) is a common nutritional disorder in the dairy and beef industries, causing significant financial losses. This study evaluates the effectiveness of computerized rumen colorimetry in detecting SARA in beef cattle. The results show a positive correlation between rumen pH and color components, suggesting computerized rumen colorimetry as a reliable method for managing SARA in bovine farms.

Summary: The study investigated the effects of Sonic hedgehog on proliferation and apoptosis of tongue epithelial cells in mice at different developmental stages. The findings suggest that Sonic hedgehog maintains cell proliferation and reduces apoptosis during tongue development and aging.

Summary: This study investigates the mechanism of yeast culture (YC) in regulating rumen fermentation. The results show that YC improves rumen papilla development, changes the structure of rumen microbiota, and affects rumen metabolic profiles.

Summary: This study aimed to describe the microscopic findings of ruminal epithelium in cattle fed diverse dietary cereal proportions and to test a new scoring system. The distribution of immune-related cells in the ruminal epithelium was found to be associated with cereal intake, and the thickness of the ruminal epithelium and cell sloughing were related to the level of cereal supplementation.

Summary: This study aimed to evaluate the effects of withdrawal of MON when associated with VM during the adaptation and finishing periods on feedlot performance of Nellore cattle. The results showed that the withdrawal of MON when associated with VM during the final third of the feedlot period improved overall final BW, ADG, and HCW when compared to bulls fed either MON or VM, but did not positively impact feedlot performance when compared to cattle that had MON withdrawn at the end of the adaptation period.

Summary: This study evaluated the effects of subacute rumen acidosis (SARA) on lactate production, absorption, circulation, and transformation in the rumen. It found that SARA accelerated the clearance rate of ruminal lactate and promoted its conversion to butyrate instead of propionate. The rumen liquid dilution rate and flow rate were lower under SARA condition. Additionally, the relative populations of certain microorganisms were significantly induced in SARA.

Summary: In disease conditions such as brain ischemia, the mammalian brain expresses various proton receptors to respond to the increase in extracellular proton concentration. These receptors play important roles in regulating ion flow and neuronal injury.

Summary: This study evaluated the effects of Saccharomyces cerevisiae and Diutina rugosa strains on preventing subacute ruminal acidosis (SARA) in sheep. The results showed that these strains stabilized ruminal pH, improved richness of rumen microflora, alleviated acidosis and inflammation, and prevented SARA in sheep, indicating potential probiotic effects.

Summary: The first experiment showed that HMBi did not affect the ratio of rumen-degradable and undegradable protein, while heat-treated soybeans increased milk, protein, fat, and lactose yields. The second experiment indicated that HMBi increased milk yield and protein concentration while reducing urinary purine derivative excretion and PUN concentration compared to control.
