Effects of Dietary Supplementation with Clostridium butyricum on Rumen Fermentation, Rumen Microbiota and Feces in Beef Cattle

Kafkas Universitesi Veteriner Fakultesi Dergisi
This study investigated how Clostridium butyricum affected rumen fermentation and the microbial communities of rumen and feces in beef cattle. Twenty beef cattle were divided into two groups: the control group (CK) and the C. butyricum group (CB, fed 2.5 x 108 CFU/kg of dry matter intake per day). The results showed that C. butyricum increased rumen pH,

Evaluation of esophageal tubing and buccal swabbing versus rumen cannula to characterize ruminal microbiota in cows fed contrasting diets

Scientific Reports
Rumen microorganisms are primarily essential for feed decomposition and nutrition of the host animal, playing a key role in the health and well-being of cattle as well as the efficiency of milk or meat production.

Degradability, rumen fermentation, and rumen microbiota of livestock rations containing different levels of Azolla pinnata.

AIMS microbiology
The scarcity of animal feeding resources has been driving the use of sustainable alternatives such as Azolla. This study evaluated the effect of replacing concentrate feed mixture (CFM) with dried Azolla (DAZ) on the in vitro digestibility of rations, rumen fermentations, gas production, and rumen microbiota. The basal diet consisted of Berseem hay and

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 ...

The Rumen Microbiota Contributes to the Development of Mastitis in Dairy Cows

Microbiology Spectrum, 2022
Mastitis is a common and frequently occurring disease of humans and animals, especially in dairy farming, which has caused huge economic losses and brought harmful substance residues, drug-resistant bacteria, and other public health risks. The traditional viewpoint indicates that mastitis is mainly caused by exogenous pathogenic bacteria infecting the ...

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 ...

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

Influence of Major Minerals on Rumen Microbiota

The Journal of Nutrition, 1988
The supply of minerals needed to meet rumen microbe requirements should match the amount of energy available for fermentation. Therefore, we attempt to assess microbial requirements for phosphorus (P), sulfur (S) and magnesium (Mg) in terms of fermentable organic matter at the rumen level (OMF) or in terms of digestible matter in the total tract (OMD).

Changes in the rumen development, rumen fermentation, and rumen microbiota community in weaned calves during steviol glycosides treatment

Frontiers in Microbiology
Early weaning leads to weaning stress in calves, which hinders healthy growth and development. As an excellent sweetener applied in food, steviol glycosides (STE) has also been shown to exhibit positive biological activity in monogastric animals. Therefore, this study aimed to evaluate the impact of incorporating STE as a dietary supplement on rumen ...
