DUAL PURPOSE CATTLE 71 



PAN-AMERICAN EXPOSITION, 1901 

 BUFFALO, N. Y. 



MODEL DAIRY SIX MONTHS' TEST 



Supplementary to the preceding essay, this and another quota- 

 tion that follows from an American Experiment Station Bulletin, 

 relate to matters of particular interest to the student of Farm Eco- 

 nomics. Mention has been made in the essay of a Six Months' Test 

 of five cows of each of ten breeds at a Model Dairy, which was a 

 unique attraction of the Pan-American Exposition, held at Buffalo, 

 N. Y., from May 1st to October 31st, 1901. At the Chicago World's 

 Columbian Exposition, held in 1893, there was a Fifteen Days' Cheese 

 Test, in which 25 of each of the three breeds Jersey, Guernsey, 

 Shorthorn took part. The summary gives the following results: 



25 Jerseys: Live weight gained 327 pounds, value $14.72, milk 12,296.4 pounds, 

 cheese 1,451.56 pounds ; cost of food $98.14, net profit $119.82. 



25 Guernseys: Weight gained 480 pounds, value $21.63, milk 10,938.6 pounds, 

 cheese 1,130.62 pounds ; food $76.25, net profit $88.30. 



25 Shorthorns: Weight gained 709 pounds, value $31.91, milk 12,186.9 pounds, 

 cheese 1,077.60 pounds ; food $99.36, net profit $81.36. 



A lady on the staff of the Buffalo Public Library kindly supplied 

 Mr. G. P. Grout with a copy of Red Polled records at the Six Months' 

 Test, and Mr. Rabald, Acting Chief of the Dairy Division, Department 

 of Agriculture, Washington, D. C., kindly sent him photo-copies of 

 the pages showing the details of the several breeds, as re-printed from 

 "Hoard's Dairyman" (Vol. 32), and published by the Bureau of Ani- 

 mal Industry in 1905 as Bulletin No. 75. The list as published in the 

 "Dairyman" showed the records as the cows were placed "in order 

 of their profit on estimated butter." The number, 1 to 50, which ap- 

 peared in the list, precedes the name of the cow. For the present 

 reprint the cows are grouped according to their breed and utility, 

 with the live weight at the beginning of the test, weight gained or 

 lost during the six months, and the percentage thereof, following 

 the name. The grouping is by Dual-Purpose and by Dairy Purpose. 

 A report was presented to the Red Polled Cattle Club of America 

 on December 4th, 1901, by the Committee of Three Messrs. J. W. 

 Martin and P. G. Henderson, and the Secretary, Mr. J. McLain Smith, 

 and in a preceding page the facts and figures relating to the breed 

 are quoted. It quoted the name, age, and date of last calving 

 which ranged from 42 to 70 days before the test began. It also 

 stated that experienced men, furnished by the various breeders' as- 

 sociations, spent months in making selections of representative breeds, 

 with the result that the Ayrshire, Jerseys, Holsteins, Shorthorns, and 

 French Canadians ["sent by the Canadian Government with one gen- 

 eral superintendent, and with each of its different herds a general 

 manager, expert in compounding rations, who was appointed by the 

 several breed associations represented, as well as an experienced 

 feeder or caretaker with each of the five herds"] were said by com-
