It will be noticed that mixed grain consisting partly 

 of cowpea meal, and hence very rich in nitrogenous ma- 

 tierial, proved superior to rice polish. 



Rice polish in different proportions. — Dui*lng the next 

 five weeks the grain mixture for lot B remained the 

 same, namely 50 per cent, cowpea meal, 25 per cent, 

 com meal and 25 per cent, rice polish. 



The grain of lot C, was so changed as to consist of 

 equal parts of corn meal and rice polish. 



Exclusive of the preliminary period the results were 



as follows:

This test was made during mid summer and the pigs, 

 confined in small, bare yards and deprived of green food, 

 did not make as rapid or as economical growth as they 

 would doubtless have done under more natural condi- 

 tions. Ordinarily we should expect that for young pigs 

 the more nitrogenous mixture fed to lot B, would prove 

 superior, as it did in the test described immediately 



above. 



Rice polish versus corn meal alone. 



During a third period of five weeks terminating Au- 

 gust 20, 1902, these same lots of shoats were used in a 

 comparison of rice polish with corn meal, both foods be- 

 ing fed alone. The amounts of grain fed to the two lots 

 were identical.

The daily rate of growth was much more rapid for the 

 pigs eating polish and these also required considerably 

 less-food to make one pound of increase in live weight.
