Fleischmann also gives the following figures :

Bonnema gives for North Dutch or Frisian cows the following 

 averages : 



Total Solids. Fat. 

 11-5 3-0 



Sugar. Protein. Ash. Solids not Fat. 

 4-3 3-5 0-7 8-5 



Liverseege gives, using analyses by James Bell, figures for the 

 composition of the milk yielded by cows of different breeds ; he 

 notes that in some cases the number of samples is too small to 

 be of much use.

Another series gave figures as follows :

Fat. Milk-sugar. Proteins. 

 5-94 4-69 3-61 



Ash. Solids not Fat.

The bulk of the samples were taken at the midday milking, 

 the average yield being only \ gallon, and the results probably 

 do not represent the true average composition.
