This study provides first deep insights into the composition of the fecal microbiota of Simmental dairy calves and might be a basis for future more detailed studies.

Overall, this study revealed a distinct mucosa-associated bacterial community at the different gut sites, and a strong effect of high Ca-P diets on the gastric community, thereby markedly expanding the authors' comprehension on mucosa -associated microbiota and their diet-related dynamics in weaned pigs.

The present findings demonstrate the stability of the bacterial community and gut environment toward dietary changes even in young pigs and results on stimulation of gastric and ileal Bifidobacterium by corn diets may be employed in nutritional strategies to support gut health after weaning.
Age-Related Differences in the Luminal and Mucosa-Associated Gut Microbiome of Broiler Chickens and Shifts Associated with Campylobacter jejuni Infection
The results demonstrate how the bacterial microbiome composition changed within the early life of broiler chickens in the gut lumen and on the mucosal surface and confirmed that the Campylobacter carrier state in chicken is characterized by multiple changes in the intestinal ecology within the host.
Microbiota of newborn calves and their mothers reveals possible transfer routes for newborn calves’ gastrointestinal microbiota

Examining faecal samples repeatedly within the first two days of life using 16S rRNA gene High Throughput Sequencing identified possible inoculation routes for the calf microbiota and showed significantly higher species richness, diversity, number of observed OTUs, and copy numbers compared to all other samples, suggesting that some of the calfFaecal microbiota may derive from inoculation from the birth canal during birth.
Epimural bacterial community structure in the rumen of Holstein cows with different responses to a long-term subacute ruminal acidosis diet challenge.

Major shifts in the 3 dominating phyla and, most importantly, a loss of diversity in the epimural bacterial communities during a long-term SARA diet challenge are revealed, in which 60% concentrate supply for 4 wk was instrumental rather than the magnitude of the drop of ruminal pH below 5.8.

This study is the first to describe the microbiota in brown hare populations and provides a foundation to generate hypothesis aiming to test the role of gut health in population fluctuations of the species.

Dietary calcium concentration and cereals differentially affect mineral balance and tight junction proteins expression in jejunum of weaned pigs

- 12 March 2015
It is indicated that high Ca diets have the potential to modify the jejunal and colonic mucosal gene expression response which, in turn, interacts with the composition of the basal diet and mucosa-associated bacteria in weaned pigs.

The present EMS effects on the bacterial community profiles were different than the previously reported RS effects and can be linked to the chemical structure of EMS.
