EXPERIMENTS IN FEEDING. 



203 



In other experiments, with 24 cows yielding between 14 and 

 20 quarts per head and per diem, the feeding lasted 80 days, 

 divided into four periods of 20 days. During the entire time of 

 feeding, all the cows had regular rations of 12 Ibs. hay, 2.2 flax 

 flour, 2.2 cotton flour, 4.4 Ibs. arachide flour, 6.6 Ibs. barley 

 bran, and 22 Ibs. oat straw, to which was added during the first 

 and fourth periods, 110 Ibs. forage beets, during the second 

 period, 17.6 Ibs. dried cossettes, and 1.67 Ibs. siloed pulps dur- 

 ing the third period. 



The nutritive value of these rations may be better understood 

 by examining the table herewith:

 DIFFERENT BEET PRODUCTS.

From which we may conclude that apparently there was very 

 little difference in the theoretical nutritive value of the combina- 

 tion used in each case. The practical results obtained showed that 

 the quantity and composition of milk obtained was as follows:
