The feed is characterized in that it contains a mixture of fatty acids, in which the proportion of C18-trans-fatty acids protected against biohydrogenation is over 50 % by weight, usually 50 - 80 % by weight. An object of the invention is also the said fatty acid mixture, a method for its preparation, as well as a method for changing the composition of the milk fatty acids, by giving to a milk producing animal an amount of said fatty acid mixture, which is sufficient to change the milk composition, preferably as a feed additive. |
