Long digestive tracts are found in most herbivores. The simplicity behind it is that it helps optimal nutrition.
While shorter digestive tracts such as found in carnivores are short to keep the distance to shedding it out as short as possible. So that it doesn't "rot" away. Plus also to minimize the surface of vowel tissue exposed to germs.

Why am I suddenly reminded of that creepy dude with the molestache who sells colon cleansing products on late-night tv?
