Étude comparée des acides gras ramifiés des aliments et du lait chez la vache

Abstract - Comparative study of branched latty acids in the lipids of cow's milk and the feed
Seven milking cows were in the experiment.
Gas-liquid chromatography was used for the determination of the branched fatty acids present in the lipids of both the feed and milk.
The amount of branched fatty acids ingested and secreted during twenty-four hours were then calculated.
The branched fatty acids in the feed lipids is only 1 per cent of the total fatty acids.
On the other hand, the branched fatty acids in milk form approximately two to three per cent of the total fatty acids. The major part of these branched fatty acids have fifteen and seventeen carbon atoms.
This corroborates the hypothesis that they are of microbial origin, at least in part
