The Relation of Food to Milk-Fat.

TABLE 111 — {Continued). 

 Weekly Pkoduct of Milk and Fat of Lot ISTo. 3. 



A clearer understanding of the variations in the per cent of fat 

 during the eighteen weeks may be obtained by finding the average 

 per cent in periods of tliree weeks each. A table of such averages 

 is given below. In order to make the study more complete, there 

 is placed in the same table the average per cents of fat found in the 

 records of three cows which were in the second experiment described 

 on page 67. The per cents are the averages for the periods of three 

 weeks each which are coincident with those in which palm nut meal 

 was fed. It will be remembered that the rations of the three cows 

 were unaltered during a term of twenty-two weeks.
