70 AGRICULTURAL EXPERIMENT STATION. [Jan. 



SUMMAKY OF EXPERIMENT BASED ON THE SaME COST OF FeED AND 



OF Manorial Value of Feed consumed as used in Preceding 

 Experiments. 



Total Cost of Feed consumed during Experiment. 

 1111.50 gals, skim milk, at 1.8 cents per gallon, 

 301.56 lbs. corn meal, at $24.00 per ton, 

 298.76 lbs. wheat br&n, at $22.50 per ton, . 

 373.28 lbs. gluten meal, at $22.50 per ton, . 

 1098.26 lbs. corn and cob meal, at $20.70 per ton, 



$20.01

Average cost of feed for production of 1 lb. dressed pork, 5.32 cts. 



Manurial Value of Feed consumed during Experiment. 



Skim milk, $10.00 



Corn meal, 1.20 



Wheat bran, 2.02 



Gluten meal, 3.26 



Corn and cob meal, 3.33 



$19.81 

 Manurial value of feed for production of 1 lb. dressed pork, 2.48 cts. 



The net cost of feed for the production of one pound of 

 dressed pork, taking the entire lot of pigs into consideration, 

 amounts to 3.69 cents. This result is the second best in 

 our whole series of experiments. This fact becomes more 

 significant when it is duly considered that the experiment 

 (VIII.) was carried out during the winter season. The 

 task of maintaining a desirable moderate temperature in the 

 piggery during the entire trial becomes more difficult in 

 winter than during any other season of the year. Low 

 temperature requires more food for the support of respira- 

 tion ; the normal condition of the animal system is apt to be 

 more seriously affected in various directions, and the gain in 

 live weight suffers usually correspondingly in case of the 

 same diet. 



To confirm, if possible, our previously advanced conclu- 

 sions still more, it was decided to repeat our mode of feed- 

 ing with another lot of pigs during the latter part of spring 

 and the summer season. An examination of our ninth 

 experiment, which is described in a few subsequent pages, 

 cannot fail to show that they are fully sustained.
