bran and middlings, $20.00 per ton; roots, $2.00 per ton; 
skim-milk, 15 cents per 100 pounds. 
It is assumed that the sow raises two litters a year, and that 
she nurses each litter six weeks. This would leave about nine 
and one-quarter months during the year that the sow would not 
be nursing pigs, and the cost of maintaining the sow during 
the time she is dry is estimated at 75 cents per month, it being 
assumed that the sow is fed as economically as possible during 
this time. The maintenance during the nine and one-quarter 
months at 75 cents per month amounts to $6.94, or, in round 
numbers, $7.00. Half of this amount, or $3.50, is charged 
against each litter, in addition to the cost of feed consumed by 
the sow and pigs before the pigs are weaned. Risk, interest on 
investment, labor, and manure are left out of the calculation. 
Twelve litters of pigs were used, which were weaned at six weeks 
old in each case.

pigs at six weeks old, the service fee and half the cost of main- 
taining the sow when dry are charged against the average cost 
of maintaining the sow and litter for six weeks, making the total 
cost as follows:
