With increasing application of yeast in fermented milk, in order to study the effect of yeast on milk protein during the fermentation process, the effects of the presence of in milk fermented by and were investigated. After fermentation, the amino acid, protein, and peptide contents were analyzed by ultra-performance liquid chromatography, two-dimensional gel electrophoresis, and liquid chromatography-mass spectrometry, respectively. After the addition of for fermentation, 25 protein spots changed significantly. These were mostly caseins and bovine serum proteins, and the content of total free amino acids increased by 16.30%; ten types of bioactive peptides were identified. Furthermore, the number of peptide types in milk fermented by increased significantly compared with milk fermented by . is considered to promote proteometabolism in milk when added with , generate flavor compounds, and improve the digestion and absorption character of milk.

Buckwheat is a common straw crop that contains an abundance of flavonoids and could be used as an antioxidant additive in animal diets. In this study, the effects of a commercial buckwheat rhizome flavonoid extract (BRFE) on milk production, plasma pro-oxidant and antioxidant, the ruminal metagenome, and ruminal metabolites in dairy goats were evaluated. Forty healthy, multiparous, nonpregnant Guanzhong dairy goats were blocked by DIM (122 ± 5.

Several factors influence the effectiveness of forage in ruminant rations, including NDF content and the physical nature, fragility, digestibility, and more of the forage. Recently, several studies suggested using the undigestible NDF (uNDF) fraction as a possible approach to achieve a more precise ration. The objective of the current study was to reduce the forage content of the diet by using the in vitro forage uNDF for diet formulation and to determine the effects on production, rumen environment, and digestibility.

Background: Galacto-oligosaccharides (GOS) intake has been linked to health benefits via modulation of the gut microbiome. Milk, where the majority of lactose is enzymatically converted to GOS (called here Novel or "N milk"), retains milk's nutritional value with reduced lactose and a high amount of prebiotic GOS.
Objectives: The aim of this study was to investigate the effect of N milk on the gut microbiome and related changes in health-related biomarkers, complemented by ex vivo fermentation experiments.

This Research Paper addresses the hypothesis that wastewater characteristics in the dairy industry vary with product type and operational procedures, and that current treatment methods face limitations in managing such variability. The study examined raw and clean-in-place (CIP) wastewater from a Serbian dairy plant over three years. Physico-chemical and microbiological analyses included pH, protein, fat, carbohydrates, total solids, total microorganisms, , Enterobacteriaceae, chemical oxygen demand (COD), total suspended solids (TSS), nitrogen (N), phosphorus (P), and dissolved oxygen (O).

This study assessed the physicochemical, microbial, and compositional properties of tiger nut yogurt with (TMYS) and without (TMYNS) starter culture, compared to conventional cow milk yogurt (CMY). The CMY exhibited the highest pH (4.
