other. In case the new-process linseed meal is used, the net 

 cost of the milk is somewhat less, on account of the larger 

 amount of fertilizing elements it contains, which increases 

 somewhat the value of obtainable manure (see rations 6, 7, 

 8 and 9). This advantage is, however, in the majority of 

 instances, to some extent compensated for by a somewhat 

 more liberal yield of milk, in case old-process linseed meal 

 has been fed. As the old-process linseed meal has a 

 well-established reputation as a suitable food constituent 

 for dairy cows, the new-process linseed meal may claim a 

 similar position in the front rank of concentrated feed stuffs 

 for dairy purposes. A careful selection of suitable associated 

 fodder constituents is, however, in both instances, necessary 

 to show their real economical value. A comparison of the 

 yield of milk obtained, in the majority of cases, during feed- 

 ing periods III., IV., with those of periods VI., VII., VIII. 

 and IX., cannot fail to render that point prominent.
