What is ruminal fermentation?
Rumen fermentation is a process that converts ingested feed into energy sources for the host. Fiber scratches the rumen wall to start a series of contractions. These contractions lead to rumination, which is the process that physically breaks down the fiber source.
What are the products of ruminal fermentation?
The end products of microbial fermentation of carbohydrates include: volatile fatty acids, mainly acetate, propionate and butyrate • gases, such as carbon dioxide and methane. Rumen microbes ferment all carbohydrates, but the soluble and storage forms are fermented more quickly than the structural forms.
What is the color of rumen fluid?
olive-green to greenish- brown
The ‘normal’ colour of rumen fluid is olive-green to greenish- brown with a sweet and fermentative smell (often described as aromatic and non-repellent). This partially resembles the composition of the diet. Cattle fed on maize silage or straw have yellowish to brown coloured rumen fluid.

What does rumen smell like?
In adult cattle the rumen fluid color is typically dark green to black, solid and liquid components are mixed and sometimes frothy, the odor is foul, pH typically ranges between 7.5 and 8.5, and the number of protozoa is greatly reduced.
What is rumen liquor?
Rumen liquor from slaughtered cattle could be used as inoculum for estimating the in vitro digestibility of ruminant feeds. This will reduce the need for fistulated cattle hence reduce the cost of management of animals and responding to issues of animal welfare.
What is ruminal microflora?
The rumen hosts a very diverse community called the microbiota. A microbiota is the whole of the ecosystem (bacteria, yeast, fungi and viruses) living in a specific environment. Intestinal microbiota was previously called “intestinal flora.” ( Bacteria, Protozoa, Fungi) 2.
How many bacteria per ml is present in the rumen?
Why should you care? Rumen microbes include the protozoa, bacteria and fungi that live inside the rumen, one of the cow’s four stomach compartments. In just 1 milliliter of rumen fluid, you can find 25 billion bacteria,1 10 million protozoa2 and 10 thousand fungi.
