BULLETIN 1296, IT. S. DEPARTMENT OF AGRICULTURE 
A little tankage and some meat scrap were used as protein supple- 
ments. Skim milk was fed in varying amounts on practically ail 
farms. Pasture consisted of alfalfa, oats, and Sudan grass. 
Table 25 gives the feed and labor requirements for hogs on the 
basis of 100 pounds of pork produced. The pounds of pork pro- 
duced represent the net gain of all hogs on the farm during the year. 
Feed requirements include the breeding herd. Pasture is given as 
the number of livestock unit days used in connection with other 
feeds to produce 100 pounds of pork. 
In no case are the labor requirements on hogs great enough to 
interfere seriously with other work. The labor on farm 9 was high, 
partly because corn was hauled direct from the field to the hogs. 
Figure 25 shows the weekly distribution of labor on hogs on a 
farm producing 8,221 pounds of pork. Four brood sows were kept 
and two litters of pigs raised.

Fig. 25.— Four brood sows were kept on this farm and two litters of pigs raised. Hogs use skim milk, 
kitchen refuse, and other feeds that might otherwise be wasted, and do well on alfalfa pasture
