dairy cattle where corn, kaffir and cane silage were compared for 
milk production. Each lot of cows was fed alternately on two 
kinds of silage for periods of thirty days with an interval of ten 
days between these periods. Following is the table showing results:

Following are some of the conclusions drawn from the experi¬ 
ment : 
1. Corn silage is slightly superior as a milk producer. 
2. Kaffir silage ranks second and cane silage third as a feed 
for milk cows. 
3. Cattle gained more readily in live weight on cane silage 
than on either kaffir or corn silage. 
4. Although kaffir and cane silage were shown to be slightly 
less valuable than corn silage, there are other factors that must be 
considered; namely, yield and adaptability to local conditions. 
Without doubt the greater yield of cane and kaffir will offset the 
slight increase in feeding value obtained from corn silage. Kaffir 
and cane are drouth-resistant crops and can be grown over a wider 
territory than corn, and from one-third to one-half more tonnage 
per acre can be obtained.
