Pork Production 



Station, 1 four at the North Carolina Station, 2 and four 

 at Purdue University. 3 The feeds in these tests are for 

 convenience reduced to a common basis by the use of the 

 Scandinavian Feed Unit System. The summarized rec- 

 ords for these twenty sows and litters are shown in 

 Table XIV. 



TABLE XIV. RECORD OF AVERAGE FEED CONSUMPTION OP 

 TWENTY Sows AND LITTERS FROM FARROWING TO WEANING 

 TIME 



Charging corn at 56 cents a bushel, or $1.00 a hundred, 

 shorts at $1.50 a hundred, tankage at $2.50 a hundred, 

 and skim-milk at 30 cents a hundred, a very satisfactory 

 combination c\f these feeds would cost approximately 

 lj cents for each feed unit contained. When corn is 

 70 cents a bushel, and protein supplements about on a 

 par in price with those just quoted, the cost of each feed 

 unit would be a little less than 1| cents, and so on. In 

 Table XV is given the cost of feeding the sow and litter 

 on the basis of 1 cent, Ij cents, 1| cents, If cents, 2 cents 

 and 2| cents for each feed unit.
