In part 2 of this experiment, IMolassine meal was used during tHe first and third 

 periods. The production of the periods decreases slightly, due to a great extent to the 

 fact thiit the cows were housed continually during comparatively warm weather. Hero 

 again the average for the two Molassine meal feeding periods is slightly lower than 

 where molasses is used, resulting in practically the same lessening in cost with the 

 latter food that was shown in part 1. 



The tests as outlined were conducted with comparatively few cows, and under 

 conditions not altogether conducive to thorougli contentment on the part of the 

 animals, and are, perhaps, rather inconclusive. One point is fairly well shown, namel.v, 

 that molasses added to the meal ration is more palatable, cheaper, and capable of i)r()- 

 ducing more milk than any of the above molasses meals used. The palatability of 

 molasses is unquestionable. During the first week of each two-week period, the cows 

 were unmistakably glad to welcome the mohissos mixed meal. When, on the contrary, 

 they were changed to the meal mixture plus the molasses meals, they showed a lack of 

 enthusiasm. Attention might here be drawn to the fact that in purchasing molasses 

 nienls. great care should be taken to examine them and ascertain that they are reason- 

 ably fresh. The matrix or solid portion of these mcnls consists in most cases of peat, 

 sphagnum moss, ground sugar cane or other more or less edible organic material of 

 an absorbent nature. With these substances, in a finely-ground state, is incorporated 

 the molasses, the whole being, when frcsldy mixed, of a soft mealy consistency and a 

 palatable nature. Wb.ere, however, large qviantities of such meals are stored, piled 

 high in warehouses, the result is a compacting of the material and, in warm weather, 



Ottawa.
