How does carb digestion differ in nonruminants vs ruminants? - ANS-nonruminants -
digest carbs with its own enzymes to simple sugars
ruminants - use microbes to ferment carbs to VFAs
How does protein digestion differ in nonruminants vs ruminants? - ANS-nonruminants -
uses its own enzymes to digest proteins to amino acids
, ruminants - microbes ferment DIP protein & build amino acids & microbial protein. UIP
escapes fermentation & passes to abomasum & intestines along with microbial protein
to be digested by enzymes
