The average results for the two sheep show that 17.94 

 (17.60) grams less hay were digested when 250 grams of 

 molasses were fed than when the hay was fed by itself; or 

 100 grams of molasses caused a depression of 7.2 grams in 

 the digestibility of the dry matter of the hay. The molasses 

 depressed the digestibility of the ash, protein and extract 

 matter of the hay. Excluding the ash, 100 grams of molasses 

 caused a depression of 4.1 grams in the digestibility of the 

 organic matter of the hay. Molasses and hay naturally 

 would not make a satisfactory combination for any kind of 

 farm stock. A more suitable ration would consist of hay, a 

 protein concentrate and molasses ; consequently, the digest- 

 ibility of the latter was tested in combination with hay and 

 gluten feed, with the following results : — 



Period VIU. 



[600 grams hay, 200 grams gluten feed, 250 grams molasses, 10 grams salt.] 



It is apparent from the above results that the sheep digested 

 only some 75 per cent, of the total dry matter of the molasses. 

 By assuming tliat the entire quantity of molasses fed was 

 digested, the following results are secured : —
