-digestive ienzymes i- iGlucose iin ithe ismall iintestine
-Absorption iinto ithe iblood icirculation
Ruminant
-CHO iin ifeed
-microbial ifermentation i- iVolatile ifatty iacids iin ithe irumen
-Absorption iinto ithe iblood icirculation
Lipids i- icorrect iAnswers i✔✔ i-- iMost ilipid iin idiets i(about i95%) iis iin ithe iform iof itriglycerides i(Esters
