43'2 Report of the First Assistant of the 



By a change in the grain for the third period, when less silage 

 was fed and more hay, the nutritive ratio was made narrower, also a 

 little narrower than it had been in the first period. The total dry 

 matter in the ration for the third period was no less, but there was 

 less digestible matter and a little lower fuel value. The cost of 

 the ration was somewhat increased. There was a diminution of the 

 milk flow but much less than the normal and the percentage of fat 

 was slightly increased. There was a small increase in the cost of 

 milk and fat production. 



During November the greatest daily average milk yield was 31.2 

 pounds and the smallest 14.9 pounds. The highest average percent- 

 age of fat was 5.90 and the lowest 2.75, For December the ex- 

 tremes in daily average milk yield were 33.1 pounds and 15,4 

 pounds, and the extremes in average percentage of fat 6.15 and 3.00. 

 For January the extremes in milk yield were 33.9 pounds and^l3.2 

 pounds and in percentage of fat 6.40 and 2.85.
