FOEAGE CEOPS IN DENMAEK 



MILK YIELD ON ONE FARM. 



The figures for the last ten days of the time of preparation 

 show how far the three groups were alike as to yield of milk. 

 To get them exactly alike is, of course, an impossibility. If we 

 look at the average percentage of fat for the whole time of the 

 experiment (in the last line on the right of the table), it appears 

 that group T had a slightly fatter milk than the other groups ; 

 but as that was also the case during the last ten days of the 

 time of preparation, this difference could not properly be 

 ascribed to the different feeding during the experiment. On 

 the other hand, there is a clear indication (in the last line on 

 the left) that the addition of roots to the fodder of groups M 

 and T has resulted in a larger yield of milk. The average 

 figures in the last line show that the cows in these groups 

 yielded about 2 Ibs. of milk more per day than those in group C. 

 More will be said on this subject when we consider the average 

 results obtained on all the farms. 



But before leaving the above table it would be worth while 

 to point out how easily a farmer might be misled by a wrongly 

 conducted feeding experiment. During the time of preparation 

 all cows had 18 Ibs. of roots a day. At the transition to the 

 period of experiment proper these 18 Ibs, of roots were gradually
