**[[Ruminant Stomach - Anatomy & Physiology|Foregut fermenters]] recieve nearly all of their energy in the form of [[Volatile Fatty Acids - Anatomy & Physioogy|VFAs]], which have to be converted to glucose by gluconeogenesis in the liver to be able to be used by the brain.

*Microbes in the foregut can convert non-proteinaceous sources of nitrogen, like ammonia and urea to all of the amino acids. Microbial protein is available to the ruminant when the microbes die and pass down into the [[The Abomasum - Anatomy & Physiology|abomasum]] and [[Small Intestine - Anatomy & Physiology|small intestine]]. Therefore ruminants can survive on a poor quality source of of nitrogen.

**Microbial protein is not available to hindgut fermenters because when the microbes in the [[Large Intestine - Anatomy & Physiology|large intestine]] die, they get excreted as there is no futher opportunity for their digestion.

*Microbes in the foregut synthesise vitamins, which are also available to the animal further on in the digestive tract.
