THE VALUE OF FISH MEAL 



The fifth and sixth weeks, therefore, the daily ration consisted 

 of 4 lbs. of herring meal, Avithout any addition of any other con- 

 centrated food. During these two weeks, therefore, 4 lbs. of 

 herring meal were backed against a mixture of 7 lbs. of cotton 

 cake, beans, and wheat ; and although there was a saving of 

 3 lbs. of mixed meal per day, there was only a loss of 1 lb. of 

 milk daily the first week, and | lb. the second week, so that the 

 smaller ration was in fact the more profitable of the two. The 

 falling off of the milk of the seven cows getting herring meal 

 (4 lbs.) was certainly much less than had been anticipated, and 

 appears to be accounted for by the food becoming better 

 balanced by the herring meal being reduced from 7 lbs. to 4 lbs., 

 the albuminoid ratio being now 1 to 3"3 instead of 2'7 as 

 formerly, as is shown by the following table : —

 Week 



Then 1'12 of oil x2i = 2-8 of starch, which, added to 7-76 starch, = a total of 

 10-56; then 10-56 of starch-f-by 3-2 albuminoids, gives an albuminoid ratio of 

 1 to 3-3. 



The seventh week a small supply of fresh herring meal having 

 come to hand, it was determined to use it in the proportion of 

 4 lbs. of herring meal to 3 lbs. of maize meal, and see how it 

 would compare with the composition which at that time was 

 being used by the rest of the herd. A change in the food 

 given was being made at that time, the cotton cake and wheat 

 being substituted by cummins, saccharine meal, and Paisley 

 meal, the same quantity of bean meal being used as formerly. 

 Cummins are the dried sprouts of barley when malting, sacchar- 

 ine meal I understand to be a bye-product, but cannot say from 

 what, while Paisley meal is maize meal with a jjortion of its 

 starch abstracted.
