Pork Production 



Station/ four at the North Carolina Station,* and four 

 at Purdue University.^ 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 of 

 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 of these feeds would cost approximately 

 Ij 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, 1^ cents, 1| cents. If cents, 2 cents 

 and 2| cents for each feed unit.
