AVERAGES OF CHEMICAL ANALYSES OF THE MILK FKOM THE DIFFERENT 

 GROUPS ON THREE FARMS. 



Very similar results were obtained by the experiments on 

 the two other farms on which only two groups were tested, 

 C and M, or C and T. 



The result of the inquiry into the effect on the composition 

 of milk produced by giving an addition of 86 (or 24) Ibs. of 

 mangels or turnips to an ordinary and sufficient food is, there- 

 fore, that the addition of roots has had no effect at all on the 

 composition of the milk. The idea, entertained at that time 

 by many Danish farmers, that the addition of roots, while 

 increasing the quantity of milk, resulted in a more watery and 

 less rich milk, milk with a smaller proportion of fat, is clearly 

 proved to be fallacious. The milk yielded by the different 

 groups, fed differently, was practically quite alike, not 

 only as regards the contents of fat, but also as regards 

 the contents of the other constituents of the milk ; the 

 milk yielded by the cows fed on roots was certainly not 

 more watery than the milk yielded by the cows which had 

 no roots. 



Quite a different answer was obtained to the question 

 whether this addition of roots had any effect on the quantity 

 of milk yielded. On account of the fact previously noted, and 

 well known to all dairy farmers, that the quantity of milk 

 gradually decreases with the increasing distance from the time 

 of calving, it is necessary to consider the quantities of milk 

 yielded both during the time of preparation, when all cows 

 were fed alike, and during the time of experiment, when the 

 cows in the different groups were fed differently. Dealing, as
