Abstract The productivity of ruminants depends largely on rumen microbiota. However, there are few studies the age-related succession microbial communities in grazing lambs. Here, we conducted 16 s rRNA gene sequencing for bacterial identification fluid samples from 27 Tibetan lambs at nine developmental stages (days (D) 0, 2, 7, 14, 28, 42, 56, 70, and 360, n = 3). We observed that Bacteroidetes Proteobacteria populations were significantly changed during growing lambs’ first year life....

Lactic acid bacteria are commonly present in various sources and possess significant probiotic properties. They can inhibit pathogenic fungi simultaneously, making them promising candidates as bio-preservatives. This study investigated two potential strains: Lactiplantibacillus plantarum LR5-2 (isolated from fermented meat products) Lacticaseibacillus rhamnosus SQ63 infant feces). The evaluated their aggregation ability, anti-pathogenic activity, safety, tolerance to gastrointestinal...

Abstract Reproductive disorders are a concern in the pig industry. Successful gestation processes closely related to suitable endometrial microenvironment, and physiological mechanisms leading failed pregnancy during peri‐implantation period remain unclear. We constructed single‐cell transcriptome profiles of embryo loss successful tissues identified 22 cell subpopulations, with epithelial stromal cells being predominant types. The two showed marked differences type composition, especially...

Gastrointestinal tract and dietary fiber (DF) are known to influence gut microbiome composition. However, the combined effect of segment long-term intake a high diet on pig microbiota metabolite profiles is unclear. Here, we applied 16S rRNA gene sequencing untargeted metabolomics investigate broad bean silage composition metabolites cecal jejunal in Durco × Bamei crossbred pigs. Twenty-four pigs were allotted four graded levels DF chow, content jejunum cecum collected. Our results...

Abstract Background As an adequate plant protein raw material, soybean meal has attracted extensive attention because of its high content, abundant amino acids essential for animals, and many functional nutrients. Feed fermentation is a new way to improve nutrient absorption animals by inoculating microorganisms, which can also play probiotic role. In order screen the lactic acid bacteria with remarkable protease-producing performance excellent growth characteristics, 1000 strains isolated...

This study evaluated the effects of Lactiplantibacillus plantarum subsp. ZA3, Artemisia argyi and their combination, on fermentation characteristics, microbial community, mycotoxins crude flavonoids content fermented soybean meal during (under anaerobic conditions) aerobic exposure conditions). The results showed that ZA3+ groups had lower pH values higher lactic acid concentrations compared with controls, additives increased abundance decreased those Acetobacter Enterobacter; in particular,...

Silage, especially whole crop corn silage (WCCS), is an important part of ruminant diets, with its high moisture content and rich nutrient content, which can easily cause contamination by mold their toxins, posing a great threat to production, food safety human health. The objective this study was examine effects lactic acid bacteria (LAB) Lactiplantibacillus (L.) plantarum subsp. ZA3 Artemisia argyi (AA) on the fermentation characteristics, microbial community mycotoxin WCCS during 60 days...

The corruption and/or poor quality of silages caused by low temperature and freeze-thaw conditions makes it imperative to identify effective starters silage fermentation technology that can assist the animal feed industry improve livestock productivity. effect L. plantarum QZ227 on wheat was evaluated under at constant temperatures followed repeated freezing thawing temperatures. became predominant strain in 10 days underwent a more intensive lactic acid bacteria than CK. accumulated acid,...

Several studies have shown that dietary fiber can significantly alter the composition and structure of gut bacterial community in humans mammals. However, few researches been conducted on dynamics assembly across different graded levels regions. To address this, 24 Durco × Bamei crossbred pigs were randomly assigned to four experimental chows comprising fiber. Results showed α-and β-diversity was between cecum jejunum. Adding chow increased α-diversity jejunum cecum, while decreased. The...

Whole-crop wheat silage (WCWS) is an excellent feed material for ruminants. However, microbial fermentation during production consumes valuable nutrients, decreasing the quality of silage. The main objective this study was to assess how addition increasing amounts Artemisia argyi (AA) affected quality, composition, and mycotoxin in whole-crop at dough stage (WCWD) ensiling aerobic exposure compared with Lactiplantibacillus buchneri (LB). 20% AA, resulted a lower pH higher lactic acid...

Mycotoxins, secondary metabolites of fungi, are a major obstacle to the utilization animal feed for various reasons. Wheat straw (WS) is hollow, and miscellaneous bacteria can easy attach its surface; fermentation frequency after silage high, there risk mycotoxin poisoning. In this study, storage process was used preserve enhance quality in WS through addition Artemisia argyi (AA), which an effective method use resources aerobic stability. The treated with AA had lower pH (AFB1 DON) values...
