Abstract
To support milk production and milk quality, ruminant animals like dairy cows are particularly fed using concentrate containing high grain and starch. Nonetheless, this type of regimen feeding could induce subacute rumen acidosis condition. Then, these circumstances cause the lysis of gram-negative bacteria accompanied by endotoxin release in gut. More importantly, gut endotoxin could be translocated to mammary gland, whereby this condition negatively affects to milk safety. The aim of the review is to update and summarize the current knowledge regarding high-grain diet and the occurrence of endotoxin in milk of dairy cows. The data suggest that there is interplay between high-grain feeding for dairy cows to endotoxin contamination in milk.

Abstract
BACKGROUND B and K2 vitamins, essential nutrients in host metabolism, can be synthesized by the rumen microbiome in ruminants and subsequently absorbed by the host. However, the B and K2 vitamin biosynthesis by the whole gastrointestinal microbiome and their abundances in different dietary strategies are largely unknown. Here, we reanalyzed our previous large-scale metagenomic data on the gastrointestinal microbiome of seven ruminant species and recruited 17,425 nonredundant microbial genomes from published datasets to gain a comprehensive understanding of the microbe-mediated B and K2 vitamin biosynthesis in ruminants. RESULTS We identified 1,135,807 genes and 167 enzymes involved in B and K2 vitamin biosynthesis. Our results indicated that the total abundances of B and K2 vitamin biosynthesis were dominant in the stomach microbiome, while the biosynthesis of thiamine, niacin, and pyridoxine was more abundant in the large intestine. By examining 17,425 nonredundant genomes, we identified 2366 high-quality genomes that were predicted to de novo biosynthesize at least one vitamin. Genomic analysis suggested that only 2.7% of these genomes can synthesize five or more vitamins, and nearly half of genomes can synthesize only one vitamin. Moreover, we found that most genomes possessed cobalamin transporters or cobalamin-dependent enzymes to consume cobalamin directly, and only a few microbial genomes possessed a complete cobalamin biosynthesis pathway. Based on these genomic data, we examined the effect of the high-grain (HG) diet on the vitamin biosynthesis of the rumen microbiome of dairy cattle. We revealed that most vitamin biosynthesis was enhanced in the HG group, while only cobalamin synthesis was inhibited in the HG group, indicating that dietary fiber is vital for cobalamin biosynthesis. CONCLUSIONS We primarily provided a gene catalog and 2366 microbial genomes involved in B and K2 vitamin biosynthesis in ruminants. Our findings demonstrated the regional heterogeneity and dietary effect of vitamin biosynthetic potential in the ruminant gastrointestinal microbiome and interpreted the biosynthesis mechanisms of these microbes and their physiological adaptability. This study expands our understanding of microbe-mediated vitamin biosynthesis in ruminants and may provide novel targets for manipulation to improve the production of these essential vitamins.

Abstract
BACKGROUND Ruminant gastrointestinal tract homeostasis deploys interactive microbiome-host metabolic communication and signaling axes to underpin the fitness of the host. After this stable niche is destroyed by environmental triggers, remodeling of homeostasis can occur as a spontaneous physiological compensatory actor. RESULTS In this study, 20 sheep were randomly divided into four groups: a hay-fed control (CON) group and a high-grain (HG) diet group for 7, 14, or 28 days. Then, we examined 16S rRNA gene sequences and transcriptome sequences to outline the microbiome-host co-oscillation patterns in remodeling of colonic homeostasis in a sheep model during adaptation to a HG diet. Our data revealed that with durations of an HG diet, the higher starch levels directly affected the colonic lumen environment (lower pH and higher fermentation parameters), which in turn filtered lumen-specific functional taxonomic groups (HG-sensitive and HG-tolerant taxa). The colonic epithelium then gave rise to a new niche that triggered endoplasmic reticulum stress to activate unfolded protein response, if the duration of endoplasmic reticulum stress was overlong, this process would regulate cell apoptosis (Caspase-3, Caspase-8, and TNFRSF21) to achieve a functional transformation. CONCLUSIONS Our results provide a holistic view of the colonic microbial assemblages and epithelium functional profile co-oscillation patterns in remodeling of colonic homeostasis during adaptation to an HG diet in a sheep model. These findings also provide a proof of concept that the microbe-host collaboration is vital for maintaining hindgut homeostasis to adapt to dietary dichotomies.

Abstract
Background Currently, little is known about the effect of sodium butyrate (NaB) on oxidative stress following grain-induced sub-acute ruminal acidosis in dairy goats. In the present study, 18 lactating dairy goats implanted with a ruminal cannula and permanent indwelling catheters in the portal and hepatic veins were randomly allocated into 3 treatment groups over 20 weeks: low grain (LG, 40% grain; n = 6), high grain (HG, 60% grain; n = 6) and high grain with sodium butyrate (HG + NaB, 60% grain + NaB; n = 6). Results When added to the HG diet, NaB increased the mean ruminal pH and reduced the levels of ruminal, portal and hepatic LPS; Additionally, we observed an increase in SOD1, SOD2, SOD3, GPX1 and CAT mRNA expression, increased levels of TSOD and CAT enzyme activity as well as increased total antioxidant capacity (T-AOC) and decreased malondialdehyde (MDA) in both the liver and plasma, while GPx activity increased in the liver of goats fed the HG + NaB diet. The mRNA expression of UGT1A1, NQO1, MGST3, and Nrf2, as well as total Nrf2 protein levels were increased in goats fed the HG + NaB diet. Conclusions Our study indicates that sodium butyrate could improve the oxidative status in sub-acute ruminal acidosis through the partial activation of Nrf2-dependent genes.

Abstract
The cecum plays an important role in the feed fermentation of ruminants. However, information is very limited regarding the cecal microbiota and their methane production. In the present study, the cecal content from twelve local Chinese goats, fed with either a hay diet (0% grain) or a high-grain diet (71.5% grain), were used to investigate the bacterial and archaeal community and their methanogenic potential. Microbial community analysis was determined using high-throughput sequencing of 16S rRNA genes and real-time PCR, and the methanogenesis potential was assessed by in vitro fermentation with ground corn or hay as substrates. Compared with the hay group, the high-grain diet significantly increased the length and weight of the cecum, the proportions of starch and crude protein, the concentrations of volatile fatty acids and ammonia nitrogen, but decreased the pH values (P < 0.05). The high-grain diet significantly increased the abundances of bacteria and archaea (P < 0.05) and altered their community. For the bacterial community, the genera Bifidobacterium, Prevotella, and Treponema were significantly increased in the high-grain group (P < 0.05), while Akkermansia, Oscillospira, and Coprococcus were significantly decreased (P < 0.05). For the archaeal community, Methanosphaera stadtmanae was significantly increased in the high-grain group (P < 0.05), while Methanosphaera sp. ISO3-F5 was significantly decreased (P < 0.05). In the in vitro fermentation with grain as substrate, the cecal microorganisms from the high-grain group produced a significantly higher amount of methane and volatile fatty acids (P < 0.05), and produced significantly lower amount of lactate (P < 0.05). Conclusively, high-grain diet led to more fermentable substrates flowing into the hindgut of goats, resulting in an enhancement of microbial fermentation and methane production in the cecum.

Abstract
The omasal epithelial barrier plays important roles in maintaining nutrient absorption and immune homeostasis in ruminants. However, little information is currently available about the changes in omasal epithelial barrier function at the structural and molecular levels during feeding of a high-grain (HG) diet. Ten male goats were randomly assigned to two groups, fed either a hay diet (0% grain; n = 5) or HG diet (65% grain; n = 5). Changes in omasal epithelial structure and expression of tight junction (TJ) proteins were determined via electron microscopy and Western blot analysis. After 7 weeks on each diet, omasal contents in the HG group showed significantly lower pH (P <0.001) and significantly higher concentrations of free lipopolysaccharides (LPS; P = 0.001) than the hay group. The goats fed a HG diet showed profound alterations in omasal epithelial structure and TJ proteins, corresponding to depression of thickness of total epithelia, stratum granulosum, and the sum of the stratum spinosum and stratum basale, marked epithelial cellular damage, erosion of intercellular junctions and down-regulation in expression of the TJ proteins, claudin-4 and occludin. The study demonstrates that feeding a HG diet is associated with omasal epithelial cellular damage and changes in expression of TJ proteins. These research findings provide an insight into the possible significance of diet on the omasal epithelial barrier in ruminants.
