milk ; quantity and quality are antagonistic ; if you 

 breed for quantity you breed away from quality and 

 vice versa" 



The following conclusions taken from Bulletin No. 

 9, of the New Hampshire Experiment Station, I have 

 as yet seen no reason to change : 



"I feel warranted in saying that a given animal by 

 heredity is so constituted that she will give milk of a 

 certain average composition ; by judicious or injudi- 

 cious feeding the amount of milk daily may be very 

 largely varied, but the quality of the product will be 

 chiefly determined by the individuality of the cow. We 

 may fertilize the soil around our grafted apple tree and 

 cause it to produce double the amount of fruit that it 

 would have produced uncared for, but we shall never 

 change the Baldwin Apple into a Pound Sweeting, or 

 the Crab apple into a Pippin ; the kind of apple is de- 

 termined by the character of the tree, the amount by 

 the character of the food ; so of the cow. A Short- 

 horn cow can never, by feeding, be changed into a 

 Jersey, and the man who starts out to increase the fat 

 in milk by simply changing the food has, in my opinion, 

 a very difficult task to perform. Slight variations 

 are always cropping out, whether we change the food 

 or not, but changes of per cent, of fat, of any consider- 

 able amount, do not appear to trace to food influence, 

 so long as the food is reasonably well proportioned and 

 sufficient in quantity. Quantity is the result of food 

 influence. Quality is the result of the make-up of the 

 animal. " 



W. H. Jordan, Maine Station, says : 



" Quality of milk is unquestionably bred into a cow, 

 and not fed in. My own convictions in regard to the 

 points which you raise are as follows : 1. The per-
