Seventh Feeding Experiment. 



Seven animals, crosses between White Chester and Black 

 Berkshire, served in this experiment. Their live weights 

 were from twenty-two to twenty-six pounds in case of dif- 

 ferent animals. The same fodder articles were used as in 

 the third, fourth, fifth and sixth experiments ; they were, 

 however, fed in different proportions. The daily ration of 

 corn meal was gradually increased during the progress of 

 the experiment, for the purpose of altering the relative pro- 

 })ortion between the nitrogenous and non-nitrogenous matter 

 in the feed. The relative proportion of one part of digesti- 

 ble nitrogenous matter to two and nine-tenth parts of non- 

 nitrogenous matter was changed at stated periods until it 

 reached 1 : 4.28. 



Average of Daily Rations. 



The cost of feed consumed varied, in case of different 

 animals, from 4.80 to 5.49 cents per pound of dressed pork 

 produced. 



Taking the entire lot of animals into consideration it 

 amounts to 5.15 cents per pound of dressed pork obtained. 

 The amount of dry matter contained in the feed required for 

 the production of one pound of dressed pork varied from 

 2.83 to 3.24 lbs.
