 Table XI. — Effect of Grain with .Pasture on Cost of Fat. 



In tables X and XI is shown the relative cost of milk and fat in the 

 two months of May and June. The cost of milk and fat was largely 

 reduced in the month of June with all the cows, but the reduction was 

 nearly three times as much with the lot thai received no grain, and by 

 a study of the column in tables X and XI showing the percentage of 

 reduction in cost of milk and butter in June, it will be seen that the 

 percentage of reduction was fairly uniform with all the cows in each 

 lot. The percentage of reduction was quite as much with those pro- 

 ducing a small amount of milk as with those producing a large amount 

 of milk. In no case was the reduction in cost in a cow having grain 

 as large as in a cow having no grain, and the average reduction for the 

 lot having no grain was nearly three times as much as for those having 

 gr9,iu. In general the milk was reduced in cost in June more- than the 

 fat, but this difference is not very marked. With the grain-fed lot 

 the cost of milk was sixty-seven per cent, and the cost of fat sixty- 

 two per cent less in June than in May; with the lot receiving no grain 

 the cost of the milk was 182 per cent and the cost of the fat 164 per cent 

 less in June than in May. It should be borne in mind that this reduc- 

 tion was effected in cows that were none of them fresh in milk and 

 most of them well advanced in the period of lactation; it is interesting
