The Question Box. 319 



What are the farmers of eastern New York receiving per gallon for 

 their mills, shipped to New York? 



Mr. Moore.— Last month, at Mount Upton, Chenango county, 

 we got $1.50 per hundred for our milk, sold on the pool system. 

 It went to factories, some into butter and cheese, while some was 

 shipped. 



Mr. Fenner. — There are 12 gallons of milk in 100 pounds. You 

 can easily figure the price per gallon. 



I have a cow giving 30 pounds of milk per day which tests 3.25 per 

 cent, of fat. If I change foods and make that cow give 10 pounds more 

 milk, will it increase the butter-fat? 



Mr. Smith. — No; provided the cow is in a normal condition. 

 As a rule, such a per cent, of increase in milk from a cow testing 

 so low^ in butter-fat, would result in a slight decrease instead of 

 an increase in fat. 



How low in butter-fat can milk be profitably produced? 



Mr. Cook. — I don't know. It would depend on the quantity the 

 cow gave. The law says that milk below three per cent, of butter- 

 fat shall not be sold, and I do not believe that a cow giving milk 

 below that per cent, ought to be kept. My opinion is that the 

 cow that gives milk containing four to four and one-half per cent. 

 of fat, with a good flow is the most profitable to keep. We are 

 keeping cows that give about 3.6 per cent, fat, and getting nearly 

 7,000 pounds of milk per cow; but I am going to put in a herd 

 of Jerseys for the purpose of ascertaining, if possible, which herd 

 (cur present one is Holstein-Friesian and its grades) will make a 

 pound of butter-fat at the smallest cost. We have found that it 

 requires about 250 pounds of butter per cow, each year, to cover 

 all the expenses for labor, feed and interest. 



Can milk be kept two weeks and give as good a test as milk kept but 

 one week? 



Mr. Cook, — There is no trouble in keeping it two weeks. We 

 keep all of ours 15 days and make tests twice a month. We use 

 bottles or cans having glass stoppers, because foreign substances 

 will adhere to corks. There are several substances that are used 

 to preserve the samples. Corrosive sublimate is as good a one as 

 any to preserve the same till we want to test it.
