rado experiments the pigs fed on a ration of shorts made Larger and 
more rapid gains than those on corn meal, but they required more 
feed per LOO pounds gain. 
Com meal compared with rice meal. -The South Carolina Station 
compared rice meal and corn meal. "The rice meal is a by-product 
of the rice mills and consists Largely of rice flour, rice polish, and rice 
bran. As yd the mills have do uniform way of putting it on the mar- 
ket, and, in order that the reader may understand what is meant by 
rice meal, as used in this experiment, it may be said that it is all the 
by-prod net obtained in cleaning the rice grain for the market. Its 
chemical composition shows that it has about the same amount of 
protein, carbohydrates, and fat as corn meal." 
The pigs used were Berkshires, about five months old, weighing about 
90 pounds each. They were given a ration consisting of 1 part meal 
and 4 parts skim milk, the milk being mixed with the meal, and were 
confined in pens 20 by 40 feet, with plenty of shade. 
The experiment was divided into two periods. During the first 
period of thirty-nine days Lot I was fed the corn-meal ration and Lot II 
the rice-meal ration; during the second period of twenty-two days the 
feed was reversed, Lot I having rice meal and Lot II corn meal. 
The results during the first period were not decisive, but during the 
second they were somewhat favorable to the rice meal. 
The results for each kind of grain for the entire experiment are as 
follows :

The corn meal was valued at 820 per ton, rice meal at $15 per ton, 
and skim milk at 20 cents per 100 pounds. This experiment shows 
that rice meal, such as was used in this test, is fully as valuable as 
corn meal in pig feeding and corroborates previous work along this 
line. 
Feeding value of rice polish. — Owing to the high price of corn dur- 
ing 1902, Duggar b devoted considerable attention to the investigation 
of the value of those feeds whose composition seemed to indicate that
