3. The velvet bean ration did not maintain the 

 -weights of the cows as well as the corn and cottonseed 

 meal mixture. 



4. The velvet beans and pods were not relished by 

 most of the cows, whether unprepared or ground to 

 a meal. 



5. Wide variations were observed as to the pala- 

 tability of the velvet bean ration with the different 

 cows. The maximum consumption was eleven pounds 

 per cow, per day, and the minimum consumption was 

 nearly four pounds per head, per day. 



6. Individual cows consuming a heavy ration of 

 velvet beans maintained their milk flow and body 

 weight. 



EXPERIMENT B 



Objects of the Experiment (Winter 1916-17). 



1. A comparison of velvet bean and pod meal ver- 

 sus cottonseed meal as a supplement to corn for milk 

 and butterfat production. 



2. Influence of velvet bean and pod meal versus 

 cottonseed meal as a supplement to corn on the cost 

 of producing milk and butterfat. 



3. Efficiency of velvet bean and pod meal versus 

 cottonseed meal as a supplement to corn in maintain- 

 ing the weights of cows in milk. 



Cow^s Used 



The cows used were pure bred Jerseys of only av- 

 erage productive ability. Length of time in milk, 

 amount of milk flow, size, and age were determining 

 factors in the selection of the two lots. / 



Plan of the Experiment 



Two lots of four cows each were used in this experi- 

 ment. A preliminary period of seven days was taken 

 to accustom them to the rations. They were then fed 

 for twenty-eight days on the following rations: 



LOT I received a mixture of 4 parts corn meal and 

 6 parts velvet bean and pod meal, and corn 

 silage. 

 LOT II received a mixture of 4 parts corn meal and 

 3 parts high grade cottonseed meal, and corn 

 silage. 

 At the close of the first period a seven day period 

 was taken in which to reverse the rations of the two 

 lots.
