By deducting 16 grams, or 16 pounds (for the digestion 

 depression), from the 70 per cent, of total organic matter, 

 molasses may be said to contain 54 per cent, of digestible 

 organic matter, equivalent to 1,080 pounds in a ton. In the 

 light of the above results, it is evident that 2,000 pounds of 

 Porto Rico molasses contain between 1,080 and 1,160 of 

 easily digestible carbohydrates, and that its crude protein has 

 little or no value as a source of nutrition.^ 



Kellner ^ considers the value of beet sugar molasses to 

 consist in its 55 per cent, of digestible carbohydrates, allow- 

 ance being made for the digestion depression. Lehmann,^ 

 as a result of three digestion experiments (9 single trials), 

 feeding hay, cotton-seed or palm-nut meal, and 200, 300 and 

 400 grams of molasses, secured a digestion depression of 11 

 per cent., or 11 grams, per 100 grams of molasses fed. De- 

 ducting this from the 71 per cent, of organic matter, he 

 declares the value of the beet molasses to consist in its 60 

 per cent, of digestible carbohydrates. 



English Hay. — This hay consisted largely of Kentucky 

 blue grass (Poa pratensis), with an admixture of more or less 

 red clover. It was cut when in bloom, well cured, and used 

 in periods V., VL, VIL, VIIL, IX., XL, XII., XIIL, 

 XIV., XV. and XVI. 



1 One is not likely to feed over 3 pounds of molasses daily to dairy stock or to horses, 

 which is equivalent to approximately 10 per cent, of the di-y matter of the total ration. 

 In our digestion experiment with hay and gluten feed, molasses constituted 20 i)er cent. 

 of tlie dry matter of the ration ; and in Lehniann's experiments, 25 per cent. If only 

 10 per cent, of the total dry matter in the daily ration should consist of molasses, the 

 question naturally arises as to whether this amount would cause so much of a depres- 

 sion as when larger quantities were fed. This matter is being investigated.
