314 FEEDING WITH SUGAR BEETS, SUGAR, ETC. 



increase per diem of the second heifer was 1.85 Ibs., and with- 

 out sugar, 1.4 Ibs. The conclusion is that the average daily 

 increase in favor of sugar varied from 0.2 Ib. to 0.4 Ib. An 

 interesting calculation has been made respecting the monev 

 profits of sugar-feeding over and above the regular rations, and 

 it is found that for the two bulls it was 11 cents, for the two 

 heifers 32 cents, which amounts are hardly worth considering. 

 Influence of Very important observations have been made respecting the 

 SUfl ^J po influence of sugar upon the quantity of milk. Experiments 

 were made upon four cows, and were conducted very much the 

 same as the foregoing. The conclusions were that sugar does 

 not increase the flow of milk, nor does it increase the fatty sub- 

 stances. It was also shown that sugar in the ration has no 

 influence upon the casein and the percentage of lactose is not 

 modified. Mineral salts were found to be 7 per cent, with or 

 without sugar. The proportion of free and volatile acids in- 

 creases in butter from cows having received sugar in moderate 

 quantities. The fact is, none of these experiments can be con- 

 sidered as conclusive; hence the importance of still further in- 

 vestigation. It is thought that if it were possible to determine 

 by a certain formula the amount of sugar to be used in com- 

 bination with a well-combined ration very different results 

 from those under consideration would be obtained, and 

 the advantages of sugar would then be demonstrated; but 

 as this has yet to be done, the present outlook does not seem 

 favorable for its general use when milk, cream and butter are 

 the objects in view. On the other hand, for fattening purposes 

 there can be no doubt that in countries where sugar is very 

 cheap, such as England, a farmer would find it to his advantage 

 to use sugar in the daily rations of animals being fattened. 

 Feeding horses As early as 1880 Prof. Grandeau commenced a series of ex- 

 wrth sugar, periments in Paris to determine what sort of feed was best 

 suited for horses, when at rest in the stable, when walking and 

 trotting, also when working slowly and rapidly, etc. All these 

 experiments, without an exception, have led to the very im- 

 portant conclusion that for the producton of energy and work 

 the most important element to be furnished is an ample supply 

 of carbohydrates; nitrogen entered the working ration to make
