The description of the processes of absorption of free fatty acids in
monogastric animals and in ruminants is the first part of the review.
The feeding problems of free fatty acids are discussed in the second p
art. In pig diets is a level up 6% free fatty acids in the dry matter
of the ration not disadvantageous. In the feeding of ruminants additio
nally free fatty acids reduce the fermentation processes in the rumen.
Only protected free fatty acids (Ca-fatty acids) are favourable in fe
eding systems for high yielding cows.
