Hindgut Fermentation is the process of digesting cellulose in herbivorous organisms.

Dogs are not foregut or hindgut fermenters. They are omnivores, so the form they receive their food in is easy to digest. Foregut and hindgut fermentation are special adaptations seen in herbivores (such as cows and horses), that allow them to deal with their difficult-to-digest food.
hindgut
Hindgut fermenters use microbes (bacteria only) and fermentaion in their hindgut, the caecum and proximal colon. Microbes that are washed out cannot be digested and therefore high-quality protein is lost. Examples of hindgut fermenters are horses, koalas, possums, wombats and pigs. (not pigs, because only herbivores have hindgut or foregut) Foregut Fermeters have two sacs (a tubiform and a sacciform fore stomach) containing lots of microbes. These microbes consume glucose from cellulose but produce fatty acids that the animal can use for energy. (Microbes can also be digested further along the digestive tract as they are also a source of protein) Forgut Fermentation is a slower digestive process. Examples of foregut fermenters are sheep, cattle, hippopotamus, wallabies and pademelons. (generally larger animals)
All ruminants (cows, sheep, goats, etc.) and kangaroos are foregut fermenters.
Humans are not foregut or hindgut fermenters. These are special adaptations that occur in herbivores (such as horses and cows).

Foregut fermentation advantages: - Allows large amounts of food to be stored for later mastication and fermentation. - The main products of fermentation have plenty of time to be absorbed - as they travel through the rest of the digestive tract. - Any microbes (bacteria) that help this process can also be digested, releasing proteins. Disadvantages: - all food is exposed to bacterial breakdown (meaning the animal can't utilize high quality protein, sugars, etc.) - easily digestible substrates can reach the bacteria (can lead to ruminal acidosis - grain overload) Hindgut fermentation advantages: - Not all food is exposed to bacterial breakdown - Protein, fat, non-structured carbohydrates can be utilized like they would be in a carnivore/omnivore - The amount of easily digestible substrates reaching the hindgut is reduced (preventing things like grain overload) Disadvantages: - only one opportunity to chew food - may not have enough time for optimal bacterial action - not all bacterial products get absorbed - lots of bacteria are lost in the faeces
Alchoholic fermentation and Lactic Acid fermentation
Moth's have three parts for their digestive systems foregut, midgut, and hindgut. Most of the work of digestions is done in the midgut, and the hindgut absorbs water and salts.

in the biostil fermentation the fermentation and distillation are coupled.
