242 FEEDING WITH SUGAR BEETS, SUGAR, ETC. 



ing the role residuum molasses could play in feeding not only 

 horses, but cattle in general. Regular weighings at regular 

 hours made known each day the live weight of the horses, 

 during rest, when working and after work. The horses drank 

 at their discretion at given hours, and the water drunk was 

 accurately measured. The weight and the composition of the 

 rations fed were accurately determined, as was also the 

 quantity of food not eaten. Under these circumstances, what 

 each horse had absorbed was known with mathematical preci- 

 sion. The droppings were collected with great care and imme- 

 diately analyzed. If out of 100 grams of nitrogenous substances 

 fed, 30 grams were found in the urine and excrements, the 

 co-efficient of nitric elements was then said to be 70, this same 

 plan being adopted for all other substances of which the ration 

 consisted. It was found that sugar had the highest coefficient 

 of digestibility under whatever form it was found or fed in 

 the fodder; the coefficient in this case was 100, meaning that 

 all the sugar had been digested by the animal none was to be 

 found in the droppings. It is interesting to note that for horses 

 of 410 kilos [902 Ibs.] live weight the nitric elimination per 

 diem through the hair, perspiration, etc., amounted to about 

 2.5 grams per diem. This item is mentioned simply to show 

 with what care these experiments were conducted. The daily 

 ambient temperature and conditions of moisture, rain, etc., 

 influencing the experiment were allowed for, and morning and 

 night the temperature of each horse was taken. We cannot in 

 this writing enter into other details; suffice it to say that when 

 the horses were working, they received, beside their regular 

 daily rations, which consisted of straw and oil cake, 2.5 kilos of 

 Vaury's molasses preparation. This represented a little more 

 than one kilo of molasses or 450 grams of sugar. The result of 

 the experiments was as follows:
