Question

How do colonic, cecal, and rumen fermentation differ? They do not differ in any significant ways. They differ sokauwhat in their anatomies, but the chemical and biological reactions occur in the same sequence and yield the same end products. Colonic and cecal fermenters first acidify their raw material, then ferment; rumen fermenters first ferment their raw material, then acidify. Cecal and rumen fermentation include an enzymatic stage, but colonic fermentation does not

Answer 1

Colonic and caecal fermenters ferment the food in hind gut after passing through the stomach. So the food is scidified first and then it is fermented in the hind gut. Where as the ruminants have a atomach with four chambers. Most of the fermentation occurs in rumen ahere the bacteria are stored. Once digested the food is absorbed and then passed in to abomassum where the protein digestion occurs. The pH of abomasum is strongly acidic killing the bacteria. So first fermentation followed by acidification occurs in ruminants like cos and buffalo. Actual process of fermentation is same.

Colonic and cecal fermenters first acidify their raw material, then ferment; rumen fermenters first ferment their raw material, then acidify.

This is the right option. Other options are not correct because there is some difference in the process between the types.
