Fatty Acids in Butter Fat

(7) In so far as it is possible to draw a general conclusion from the 
data thus far secured from all experiments (j5, 16) made at this station 
extending over many years, it seems evident that neither protein nor 
carbohydrates have any appreciable influence in changing the chemical 
composition of the butter fat; on the other hand, different oils and fats 
do modify to an extent the chemical composition of butter fat, the 
modification depending upon the composition of the oils and fats fed.
