Abstract
Rumen degradability and intestinal disappearance of encapsulated fats (Prolip) and calcium soaps (Megalac) were determined using the in sacc o technique. Compared with Megalac, fats associated with rumen by-pass protein had higher rumen degradability of both dry matter (44 vs 10%) and fatty acids (63 vs 15%). The in sacco intestinal disappearance of fats that escaped rumen digestion was significant: 77% for Prolip and 87% for Megalac.
