THE ECONOMIC FEEDING OF WORKING HORSES. 955 
The whole daily ration is then per 1,000 lb. live weight :— 
1:13 Ib. digestible albumenoids. 
13:31 lb. digestible carbohydrates (including 0:24 lb. fat). 
Albumenoid ratio, 1: 11°8; also 1:80 lb. salts. 
Tt is thus seen that the full proportion of carbohydrates const- 
dered necessary by Wolff for a hard-working horse has been 
experimentally arrived at in these trials, but that only half the 
orthodox proportion of albumenoids has been found necessary, 
and only half the fat. Probably the warmth of the tropical 
climate renders the smaller proportion of fat sufficient, but the 
satisfactory results obtained with the reduced proportion of albu- 
menoids prove that the current theory on the matter is erroneous. 
The conclusions that can fairly be drawn from the trials that 
have been made are :— 
1. That for working horses the sugar in cane molasses is a 
satisfactory substitute for starchy food, being readily digested and 
transformed into work. 
2. That 15 lb. of the molasses can be given per day to a 1,270 
Ib. working horse, with advantage to the health of the animal 
and to the efficiency of its work. 
3. That it produces no undue fattening, softness, nor injury to 
the wind. 
4. That the high proportion of salts in it has no injurious 
effect. 
5. That an albumenoid ratio as low as 1:11-'8 has proved 
highly suitable for heavy continuous work when a sutticient 
quantity of digestible carbohydrates is given.
