Table VI. — Record of the Cows Remaining on the Private Farm Compared 

 With Those Taken to the University. 



From the above it will be seen that there was quite a uniform de- 

 crease in the percentage of fat in 1903. In fact, the only two cows 

 that gave richer milk in 1903 than in 1900 were Dena and Polly and 

 these were the two cows that were farrow when they were returned 

 to Mr. Gibson, a fact which probably accounts in large part for the 

 increased percentage of fat in their milk in 1903. It would seem, 

 therefore, that the lower average percentage in 1903 could not well 

 be ascribed to any treatment or conditions to which the cows were 

 subjected while at the university. 



The Effect on Total Quantity of Milk and Fat. 

 An inspection of Table III shows that the total yield of both milk 

 and fat was in nearly every case much increased while the cows were 

 at the university. While this was incidental to the main object of 

 the experiment, it has a most important practical bearing, and illus- 

 trates most forcibly the capacity of many cows for increased produc- 

 tion^imder more liberal feeding. It is true that in Table III the total 

 record for the whole lactation period is given, and since most of the 

 cows milked longer in 1901 than in 1900 the yields are not readily 

 comparable. We have therefore calculated the yield of each cow 

 in 1900 and 1901 on an average weekly basis for the time she was in 

 milk and the results are given in the table below:
