FARM ORGANIZATION IN SOUTHWESTERN MINNESOTA 
59 
tankage is fed, but skim milk is the principal protein concentrate on 
most of these farms. The pasture includes rape, alfalfa, clover, 
timothy, and bluegrass. 
The feed and labor requirements for pork production are presented 
in Table 41. The pounds of pork produced represent the net gain in 
weight of all hogs on the farm during the year. The weights of hogs 
sold for either market or breeding purposes, of hogs butchered for 
farm consumption, and of hogs on hand at the end of the year are 
added together and from their sum is subtracted the weight of hogs on 
hand at the beginning of the year and any purchased during the year. 
The remainder is the net worth of pork produced during the year. 
No allowance is made for hogs that die during the year, hence this 
figure is net in that it covers death risk. The feed is shown o.n the 
basis of the requirement for the production of 100 pounds net gain in 
weight. It includes feed for the breeding herd that produces the pigs 
which are fed for market.

1 Farms are arrayed in order of total pork production per farm, beginning with the lowest 
s See footnote 2, Table 37, p. 49. 
CAUSES FOR VARIATIONS IN FEED REQUIREMENTS FOR HOGS 
There were over seven pigs per litter on farm 15, which had one of 
the lowest grain requirements for hogs. On farm 21, having the 
highest requirements, there were only three pigs per litter. Since the 
feed fed to breeding stock is charged against the hogs actually 
marketed, the larger the litters the smaller will be the portion of the 
charge against an individual hog. 
On farms 6 and 13 the high feed requirements are in part due to the 
fact that the brood sows were largely aged sows weighing 400 to 500 
pounds. On most farms gilts of only about half these weights were 
used. On farm 2, with the lowest feed requirement, no feed for
