Twenty-three milking cows were in thi'ee groups, according to their periods 

 of lactation, for the experimental dairy tests reported upon in Tables V to X of the 

 dairy experiments recorded in Part III of this report. 



The ration fed from 7th to 13th December was composed of: — 



I Lb. 



Corn ensilage 40 



Mangels 35 



Straw 5. 



Meal (barley, pease, oats) 5

The ration fed from 14th to 27th December was composed of : —

Corn ensilage 40 



Sugar beets 35

The milk was carefully weighed, the specific gravity was taken by the lacto- 

 densimeter, and the percentage of fat was ascertained by the Babcock milk tester. 

 The following Table shows the average results : —

This experiment does not indicate that there was any appreciable ditference in 

 the quantity or richness of the milk, due to the substitution of sugar-beets for 

 mangels. An examination of the butter which was made revealed the fact that the 

 butter made during the period when sugar-beets were fed had a firmer body and a 

 finer flavour than that which was made during the period when mangels were being 

 fed. 



Feeding Calves. 



Yevy many enquiries have come to the office by mail, asking for information and 

 advice on the feeding and raising of calves for the dairy. At my suggestion one of 

 my assistants in the Dairy Commissioner's branch, Mr. J. W. Hart, prepared the 

 following short article on that subject. Mr. Hart has proven by his work that he 

 has special aptitude and ability in the care of dairy stock; and I consider the matters 

 of advice contained in his article to be so much to the point, and capable of so much 

 service to the stock-raisers of Canada, that I introduce it here in his own bright 

 language.
