CORN-MEAL, MIDDLINGS, AND SEPARATOR SKIM- 

 MILK FOK FATTENING PIGS. 



BY EDWAKD L. SHAW. 



This experiment was started December 1, 1903. The object 

 was (1) to compare the feeding value of separator skim-milk 

 when fed with corn-meal and with middlings, and (2) to com- 

 pare the feeding value of corn-meal and middlings. 



PLAN OF THE EXPERIMENT. 



Twenty Yorkshire pigs, from twelve to thirteen weeks old 

 and of uniform size, were selected and divided into four lots, 

 five pigs in each lot. The pigs were all numbered with the 

 Dana label, weighed every ten days, and the weight of each 

 pig carefully recorded. 



The pigs were fed on the experimental ration for a few days 

 to become accustomed to the change before the initial weights 

 were taken. 



In selecting the twenty pigs for the exj^eriment, ten sows and 

 ten barrows were chosen, so as to compare the gains made by 

 the sows with the gains made by the barrows. 



The sows and barrows were divided in the four lots as fol- 

 lows: 



Lot I, two sows and three barrows. 



Lot II, two sows and three barrows. 



Lot III, three sows and two barrows. * 



Lot IV, three sows and two barrows. 



The experiment was divided into two sixty-day periods. 

 During the first sixty-day period the four lots were fed as 

 follows:
