Vitamin B12, for one.
The acetic acid that's produced in the rumen gives it that vinegar smell.
Ruminants require specific nutrients such as high levels of fiber, particularly cellulose, which they can effectively digest due to their unique digestive system, including the rumen. They also benefit from volatile fatty acids (VFAs) produced during fermentation in the rumen, which serve as a primary energy source. Additionally, ruminants need specific vitamins, such as vitamin B12, which are synthesized by the microbes in their rumen. Non-ruminants, like pigs and chickens, do not have the same fermentation capabilities and thus have different nutrient requirements.

A rumen fistula is a surgically created entry to the rumen in the left flank of the ruminant, typically permanent and with a rubber or similar material device (a 'cannula') fitted to close it between times of use. It enables the rumen contents to be accessed, and the rumen wall to be viewed and biopsied. Surgically modified ruminants such as these are only found on research farms, where they are used to study rumen function. Looking in through the fistula, you can see the rumen contents and the rumen wall.

In cows, vitamins are metabolized through a combination of absorption in the digestive system and conversion to active forms. Fat-soluble vitamins (A, D, E, K) are absorbed in the intestines along with dietary fats, while water-soluble vitamins (such as B vitamins and vitamin C) are absorbed directly into the bloodstream. The liver plays a crucial role in storing and converting these vitamins into their active forms, which are then utilized for various physiological functions. Additionally, rumen bacteria can synthesize certain B vitamins, contributing to the cow's overall vitamin supply.
