THE FEEDING VALUE OP BOOTS

before, with the averages for the three farms, the result appears 

 from the following table : 



AVERAGE QUANTITY OF MILK YIELDED BY TEN Cows DAILY. 



When a correction is made for the slight difference in yield 

 during the time of preparation, it is found, as a result of giving 

 an addition of 36 Ibs. of roots daily per cow, that group M gave 

 24 Ibs. more milk for 10 cows daily, and that group T gave 

 14 Ibs. more milk, when comparing in both cases with the yield 

 of group C. 



As straw was given ab lib., it is possible that a different 

 consumption of straw may have had an effect on the yield of 

 milk. The quantities of straw consumed daily by 10 cows 

 averaged during the time of experiment : 



The small amount of straw consumed on the third farm was 

 due to the large amount of hay (equal for all groups) fed on that 

 farm. It will be seen that the addition of mangels on the first 

 farm seems to have caused a saving in straw, but otherwise 

 there is no great difference in the amount of straw consumed. 



It is necessary, however, to notice also what effect the 

 addition of roots had on the weight of the cows. That appears 

 from the following table, giving the average weight of the cows 

 in each group on each farm at the beginning and at the end
