SVVINK REARING WITH DAIRYING 433 



Previous experiments at the Tennessee station (Bul- 

 letin No. I, Volume XV) had been made to compare corn 

 meal with other rations involving skim milk and whey. 

 The first lot in the following table was fed a ration of 

 12 pounds of corn meal and 20 pounds of water, which 

 was increased to 16 pounds of corn meal and 2,2 pounds 

 of water later on. The second lot was given 12 pounds 

 of corn meal and 36 pounds of skim milk a day at first, 

 and 16 pounds of corn meal with 80 pounds of skim milk 

 toward the end of the experiment. The third lot was 

 given a daily ration during the early part of the test of 

 eight pounds of corn meal and 24 pounds of skim 

 milk, which was later changed to y/2 pounds of 

 wheat meal, I2j/^ pounds of corn meal and 80 pounds 

 of whey. The first ration of the last lot was com- 

 posed of 5 1-3 pounds of corn meal, eight pounds 

 of cowpea hay, and 16 pounds of skim milk; this was 

 changed to 11 pounds of corn meal; three pounds of 

 chopped cowpea hay, and 53^^ pounds of skim milk. 

 The last lot proved an unprofitable one, but the experi- 

 ments demonstrated the high value of dairy by-products 

 in connection with corn and wheat meals. The pigs 

 averaged about 135 pounds at the beginning of the tests, 

 when they were bought on the market at 4^ cents 

 a pound. They were sold for 5)^ cents a pound, and at 

 that price it was estimated that 66.7 cents per bushel was 

 received for the corn used. In the following summary 

 of results, skim milk was valued at 22 cents per 100 

 pounds, and whey at half that sum. with the following 

 prices per ton for the other feeds : Corn meal, $17 ; wheat 

 meal. $25; cowpea hay, $13.50.
