THE FEEDING VALUE OF BOOTS 



23 



e after this, during which time the cows were again all fed 

 alike. This was done for the purpose of finding out whether 

 the differences in yield observed during the time of different 

 feeding would disappear and the various groups yield alike 

 when they were again fed alike. 



The composition of the milk, according to the full analysis, 

 and particularly its contents of fat, were so nearly alike through- 

 out that it would not seem justifiable to ascribe the small differ- 

 ences observed to the effect of the different feeding. It will 

 be sufficient in this naturally very abridged description to give 

 the average percentages of fat in the milk per group for the 

 four farms with four groups each : 



The average quantities of milk yielded per cow in 10 days 

 (or by 10 cows in one day) per group for the four farms were as 

 follows : 



The average weights of the cows and the average increases 

 in weight per cow in ten days during the time of different 

 feeding and afterwards are given in the next table : 



1 Loss of weight.
