6. Oondusions. 



1. The nutritive ratio of the feed varied in 1890 from 

 1 : 4.60 to 1 : 6.25, with an average of 1 : 5.19 ; in 1891 from 

 1 : 4.17 to 1 : 6.74, with an average of 1 : 5.17. 



2. The amount of fat in the milk varied in 1890 from 

 4.38 per cent, to 5.09 per cent., with an 'average of 4.70 

 per cent. ; in 1891 it varied from 4.15 per cent, to 5.21 per 

 cent., with an average of 4.68 per cent. 



3. The percentage of total solids varied in 1890 from 

 13.37 to 14.80; in 1891 from 13.41 to 14.99, with an aver- 

 age for 1890 of 13.99 and for 1891 of 14.18. 



4. The total cost of feed for one quart of cream amounts 

 in 1890 to 14.12 cents, and in 1891 to 12.83 cents. 



5. The net cost of feed for one quart of cream amounts 

 in 1890 to 6.10 cents, and in 1891 to 5.24 cents. 



6. The value received for one space of cream varied in 

 1890 from 3 to 4 cents, with an average of 3.47 cents; in 

 1891. from 3.10 to 4.10 cents, with an average of 3.71 cents, 

 which amounts per quart (average) in 1890 to 11.80 cents 

 and in 1891 to 12.61 cents. 



7. The number of quarts of milk required to produce 

 one space of cream in 1890 was 1.61, and in 1891, 1.70, 

 or 5.47 quarts of whole milk to produce one quart of cream 

 in 1890 and 5.78 quarts to produce one quart of cream in 

 1891. 



8. The net cost of feed per quart of cream averages in 

 1890, 6.10 cents and in 1891, 5.24 cents. We received per 

 quart of cream in 1890, 11.80 cents and in 1891, 12.61 cents, 

 thereby securing a profit of 5.70 cents per quart in 1890 and 

 7.37 cents in 1891. 



From these statements it appears, as has already been 

 claimed in previous reports, that close fodder rations tend 

 to improve the quality of the milk as well as the condition 

 of the animal. The introduction of dried brewers' grain and 

 cotton-seed meal into the daily diet has apparently lowered 

 to a considerable extent the net cost of feed.

 annual report, pages 54 to 65.
