188 The Guernsey Breed 



test, and that none of the Guernseys continued after the sec- 

 ond 3'ear. 



The table on page 187 gives a complete summary of the 

 w'lrk as far as they carried it. 



AVhile the number of individuals in\'oh-ed in this experi- 

 ment is small, tlie results bear out other similar tests in prov- 

 ing that in ecnnrmiy of butterfat production the Guernsey has 

 no superior. 



In 1900 Prof. F. W. Woll, of the University of Wisconsin, 

 published in the Breeders' Gazette a compilation of the aver- 

 age annual ]jniductirin of 18'') cows of difTerent breeds, all of 

 which had l)een at different American experiment stations, 

 and the results are as follows:

It will be noted by this table that not only did Guernseys 

 lead in the a\-erage production of butterfat, but also that they 

 |iriiduccd this at a lower food cost than the cows of any other 

 l)rced, with tlie exception cif the single Polled Angus cow, 

 with a productidu much lower than that of the Guernsevs. 



The cost of foi.nl reiiuireil for the production of milk and 

 fat was as follows :

In 1893 there was carried "n at the World's Fair at Chi- 

 cago a very exhaustive breed test, in which 25 cows of the 

 Jersey, the Guernsey, and the Shorthorn breeds were entered. 

 'Hie test was divided into three periods, the first being from 

 May 16th to Alay 26th, in which a test for the production of 

 cheese was carried on: the second of 90 days from June 1st to 

 August 29lh, fur the pniductinn of butter ;'an(l tlie "third of 30 

 days' duration. At each change of period breeders were al-
