"In neither of these eases did Nutriotone seem to have any effect, favorahle or 

 unfavorable. The slightly smaller milk flow -with Nutriotone does not mean anything 

 in particular except to add increased emphasis to the falseuess of the claim that 2 

 large tablespoonfuls fed with each feed 'will produce a great increase of much 

 richer milk.' " 



Beinarks are made on the use of condimental food, and a tonic is 

 recommended for use when animals are out of condition and in need 

 of such treatment. 



The food requirements and production of different breeds of 

 cows, E. Gripenberg- (Tidn. Mjolkhushall, 6 (1897) Nos. 31-37). — The 

 paper gives a discussion of the comparative economy and productive 

 capacity of Holstein, Ayrshire, Angler, and Finnish breeds of cows 

 and of crosses, kept at the Mustiala Agricultural and Dairy Institute, 

 from 1885-'96. Tables giving the amounts of hay and concentrated food 

 consumed and milk produced during each year for the various breeds 

 are included in the paper. The quality of the milk produced was 

 unfortunately only ascertained during 4 years, 1S89-'91 and 1890. The 

 members of u food units "given in the table refer to hay and concen- 

 trated food consumed, the value of the former being considered one- 

 half that of the latter. Pasturage was the same for all cows, and the 

 quantities of straw and roots (or silage) eaten were considered compen- 

 sated for by the manure produced by the cows. 



Production and relative economy of different breeds of cows. 



Valuing a food unit at 2 cts., milk at 2 cts. per kilogram, butter at 43 

 cts. per kilogram, and skim milk at 0.6 ct. per kilogram, the author 

 arrives at the following figures, which indicate the profit per year and 

 per cow for the different breeds : Holstein $38, Aryshire $33, Angler 

 $20.50, crosses $38, and Finnish native $23. — P. w. woll.
