~The average weight of the cows for a year was 816 oan and 
the average daily amount of dry matter in their food was 17. 34 
‘pounds, or for 1,000 pounds weight 21.2 pounds. 
The following table gives for seven cows the average yield of 
‘milk as also of milk fat, and the pounds of albuminoids and erude © 
fat present in the foods fed during November and December. The 
rest of the herd had ceased giving milk or were so nearly dry that — 
they were excluded. 
These results are highly interesting as showing a change in 
milk production in cows averaging a year in lactation. 
We find here a reverse in the average results since we have: 
1. An increase in mild yield of 5.5 per cent. 
2, An increase in the milk fat produced of 2.4 per cent. 
3. A decrease in the per cent of fat in the milk of 3.1 per cent. 
By reference to table on page 77, we shall see that as an 
average we found between the twelfth and thirteenth months of 
lactation: 
1. A decrease in milk yield with eight cows of twelve per cent. 
2. A decrease in fat produced of 5.5 per cent. 
3. An increase in per cent of fat in milk of 1.7 per cent. 
We observe that there was an increase of albuminoids in the 
foud of December of 7.6 per cent over the amount in November, 
and an increase of the amount of crude fat in the food of 8.4 per 
cent. 
The change in the quality of the food was an increase of fifty 
per cent in the amount of ensilage, and a decrease of one-third in 
the amount of hay fed, also the substitution during December of 
cotton-seed meal for corn meal in the grain mixture. 
The nutritive ratio for November was 1. to 5.8 and for 
December one to_5.2.
