Results of experiments in lot I, in which kafir silage was compared 

 with corn silage, indicate that corn silage is slightly superior to kafir silage 

 for milk production. The cows^showed a loss in live weight, however, when 

 changed from kafir to corn silage. The increase of twenty-seven pounds in 

 milk production in favor of corn is very slight for the lot, as this is the 

 increase of six cows for thirty days, or less than one-sixth of a pound of 

 milk daily to the cow. The kafir silage proved more fattening than the 

 corn silage. 



Cane and kafir silage were compared in lot II. The results obtained 

 here are more striking than those secured in the other lots. Kafir silage, 

 according to these results, is much better than cane for milk production. 

 Upon comparison of the production during the periods in which the cows 

 received cane silage with the period in which the received kafir silage, it 

 is found that for a thirty-day period in each case, the five cows produced 

 231 pounds more milk on the kafir silage than on the cane silage. This
