Principal absorptive organ in horse is _______.
-
colon
-
rumen
-
ceacum
-
All of the above
A
Correct answer
Explanation
Horses are hindgut fermenters, and their colon is the principal site for nutrient absorption, particularly volatile fatty acids produced by microbial fermentation. Unlike ruminants (which have a rumen), horses rely on their enlarged colon for both fermentation and absorption. The rumen and ceacum are not the primary absorptive organs in horses.
