The nutritive ratio of the hay when fed alone was 1 :7.5, 

 and of the hay-molasses ration, 1:10.1; molasses constituted 

 21.4 per cent, of the dry matter of the hay ration. The digestion 

 depression is very noticeable, especially with Sheep 11. The 

 average depression for both sheep was 13.50 grams of dry 

 matter and 10.03 grains of organic matter per 100 grains of 

 molasses. The total average depression was equivalent to 18.2 

 per cent, of the dry matter of the molasses consumed. The 

 feeding of 200 grams of molasses caused an average loss of 7.4 

 per cent, in the digestibility of the hay. No particular change 

 was noted in the live weight of either animal.

The nutritive ratio of the hay-molasses ration was 1: 11.2, 

 and molasses constituted 20.0 per cent, of the dry matter of the 

 total ration. The results show that 17.94 (17.00) grams less 

 hay were digested when 250 grams of molasses were fed than 

 when the hay was fed by itself ; or 100 grains of molasses caused
