Summary: Comparing the rumen contents collected by oro-esophageal tubing and rumen cannula, it was found that there were slight differences in the microbiome and metabolome. However, the overall microbiome composition and diversity were similar between the two methods. This suggests that oro-esophageal sampling can be used as a proxy to study the rumen microbiome compared to the traditional rumen cannula technique.

Summary: This study investigated the effects of mutating two amino acids in the regulatory tail of NHE1 protein. The mutations led to changes in protein activity, molecular weight, and conformation, indicating the importance of these amino acids in enzyme kinetics and protein structure.

Summary: This study found that there are two bacterial clusters in the rumen of goats: P-cluster and R-cluster. Compared to P-cluster goats, R-cluster goats have higher growth rates and concentrations of propionate, butyrate, amino acids, and unsaturated fatty acids. The bacteria enriched in the R-cluster have negative correlations with the bacteria enriched in the P-cluster. These results shed light on improving the growth performance of ruminant animals.

Summary: The study investigated the effect of high sulfur diet on digestion and morphology of the ruminant gastrointestinal tract through in vitro and in vivo experiments. Results showed that adding sulfur in feed decreased methane production but increased hydrogen sulfide gas. It also led to changes in the rumen microflora and morphology of rumen epithelium.

Summary: Our understanding of essential hypertension is extensive, and while its treatment is well-known, not all individuals with hypertension are salt-sensitive. Even normotensive individuals may face increased cardiovascular risks with a high salt diet. Research on the mechanisms and treatment of hypertension sensitive to high-sodium diets is crucial.

Summary: This study evaluated the effects of phytogenic feed additives on subacute ruminal acidosis and found that adding phytogenic compounds to acidogenic diets can reduce the risk of the disease and improve rumen fermentation. Additionally, phytogenic supplementation also reduces inflammation.

Summary: The study found that changing diet from high-forage to two succeeding high-concentrate diets, and then back to high-forage diet, significantly impacted ruminal fermentation parameters, bacterial community composition, and expressed genes in Holstein Friesian cows. Specifically, during the high-concentrate diet period, ruminal pH decreased, while ammonia nitrogen and volatile fatty acid concentrations increased, and bacterial richness and diversity decreased. The diet transitions also influenced gene expression in rumen epithelia.

Summary: The purpose of this study was to investigate the effects of different particle sizes of rice straw on rumen protozoa count, nutrient disappearance rate, rumen fermentation, and microbial community. The study found that the organic matter disappearance rate and concentrations of volatile fatty acids were highest in the 4 mm group. These results suggest that a particle size of 4 mm may improve nutrient disappearance rate and promote volatile fatty acid production by regulating ruminal microorganisms.

Summary: The study found that dietary thiamine supplementation can alleviate rumen epithelium inflammation and barrier function in goats fed a high-concentrate diet. Results showed that the HCT group had significantly higher concentrations of metabolites compared to the HC group, indicating that thiamine supplementation promotes rumen epithelial growth.

Summary: This study evaluated the effects of Biochanin A (BCA) on lactation performance, nitrogen metabolism, and health in dairy goats. The results showed that BCA treatment significantly improved milk production, milk protein and fat content, and enhanced antioxidant capacity. Additionally, BCA positively influenced nitrogen metabolism and the rumen microbiome of dairy goats.

Summary: The study evaluated the effects of selenium yeast on rumen fermentation parameters and microbial diversity in goats. Results showed that different dosages of SY had varying impacts on the organic acid content in ruminal fluid, highlighting the importance of SY supplementation in modulating rumen fermentation and microbial ecology.

Summary: The study found that feeding goats with feed containing 6% Purple Neem foliage and 3% sunflower oil increased feed consumption, nutrient intake, nutrient apparent digestibility, and nitrogen utilization. This feeding regime also led to improved rumen fermentation, microbial population, plasma antioxidant activity, meat quality, and fatty acid profile in goats.
