Rumen microbiota and dietary fat: a mutual shaping [PDF]

Journal of Applied Microbiology, 2017
Although fat content in usual ruminant diets is very low, fat supplements can be given to farm ruminants to modulate rumen activity or the fatty acid (FA) profile of meat and milk. Unsaturated FAs, which are dominant in common fat sources for ruminants, have negative effects on microbial growth, especially protozoa and fibrolytic bacteria. In turn, the

Host genetics influence the rumen microbiota and heritable rumen microbial features associate with feed efficiency in cattle

Microbiome, 2019
Background The symbiotic rumen microbiota is essential for the digestion of plant fibers and contributes to the variation of production and health traits in ruminants.

The Temporal Dynamics of Rumen Microbiota in Early Weaned Lambs [PDF]

Microorganisms, 2022
Weaning affects the development of ruminal bacteria in lambs during early life. However, the temporal dynamics of rumen microbiota in early weaned lambs is unknown compared to conventionally weaned lambs. In this study, one group was reared with their dams (control, CON) and conventionally weaned at 49 days (d), while the other lambs were weaned at 21 ...

Sex differences in rumen fermentation and microbiota of Tibetan goat [PDF]

Microbial Cell Factories, 2022
Background The gut microbiota play an important role in maintaining host metabolism, the immune system and health, while sex, genotype, diet and health have specific effects on the composition of the gut microbiota.

Perturbation dynamics of the rumen microbiota in response to exogenous butyrate. [PDF]

PLoS ONE, 2012
The capacity of the rumen microbiota to produce volatile fatty acids (VFAs) has important implications in animal well-being and production. We investigated temporal changes of the rumen microbiota in response to butyrate infusion using pyrosequencing of ...

Gut/rumen-mammary gland axis in mastitis: Gut/rumen microbiota–mediated “gastroenterogenic mastitis”

Journal of Advanced Research
Mastitis is an inflammatory response in the mammary gland that results in huge economic losses in the breeding industry. The aetiology of mastitis is complex, and the pathogenesis has not been fully elucidated. It is commonly believed that mastitis is induced by pathogen infection of the mammary gland and induces a local inflammatory response. However,

Impact of rumen cannulation surgery on rumen microbiota composition in Hanwoo steers

Journal of Animal Science and Technology
Rumen cannulation is a surgical technique used to collect rumen contents from ruminants. However, rumen cannulation surgery may potentially impact the composition of the rumen microbiota.

Effects of Thymol Supplementation on Goat Rumen Fermentation and Rumen Microbiota In Vitro [PDF]

Microorganisms, 2020
This study was performed to explore the predominant responses of rumen microbiota with thymol supplementation as well as effective dose of thymol on rumen fermentation. Thymol at different concentrations, i.e., 0, 100 mg/L, 200 mg/L, and 400 mg/L (four groups × five replications) was applied for 24 h of fermentation in a rumen fluid incubation system ...

Live Bacillus subtilis natto Promotes Rumen Fermentation by Modulating Rumen Microbiota In Vitro

Animals, 2021
Previous studies have shown that Bacillus subtilis natto affects rumen fermentation and rumen microbial community structure, which are limited to detect a few microbial abundances using traditional methods. However, the regulation of B. subtilis natto on rumen microorganisms and the mechanisms of microbiota that affect rumen fermentation is still ...

Effect of Cistanche deserticola on Rumen Microbiota and Rumen Function in Grazing Sheep

Frontiers in Microbiology, 2022
For a long time, veterinary drugs and chemical additives have been widely used in livestock and poultry breeding to improve production performance. However, problems such as drug residues in food are causing serious concerns. The use of functional plants and their extracts to improve production performance is becoming increasingly popular.
