Agricultural Experiment Station, Ithaca, N. Y. 



Tlie gain in live weight of lot II over lot I was about twenty- 

 one per cent, and this very nearly reprasents the amount of dry 

 substance consumed over that consumed by lot I. 



It will be observed from Tables V and VI that the gain of the 

 individuals of lot 11 were much more imiform than the gain of 

 the individuals of lot I. This condition has frequently been 

 observed in experimental feeding at this station, that where nitro 

 genous and carbonaceouis rations have been compared, the gain of 

 individuals of the nitrogenous lots have been more unifonn; this 

 may be only a coiD.cidence and not a law, but the results of experi- 

 ments already made will w arrant a closer observation concerning 

 this point in future investigations. Although the results of this 

 experiment give no marked difference in gain of one lot over the 

 other, the results obtained may be of value to the feeder to give 

 some definite figures concerning the gain from the food consumed. 

 Table IX gives a summary of foods consumed and gain in live 



weight obtained.

Nitrogenous and Carbonaceous Rations for Pigs. 



December twenty-third, four Poland China pigs were selected 

 from the University herd and divided into two lots of two each 

 for experimental feeding, to make a test of the difference between
