times a day, and at each feed should be given just a trifle less than 
they will eat up clean. The profits come from inducing the hog 
to consume a large quantity of grain and maintain a sharp appe¬ 
tite. The feeder will secure the best results by watching the hogs 
each time until they finish eating. He will then know whether the 
hogs are slow about cleaning up the feed, showing over feeding, 
or whether they clean up the feed quickly and need more. 
The hogs should have all the clean, pure water they will drink 
at least three times a day. Colorado feeds are rich in protein, 
and a hog eating them needs much, more water than when eating 
corn. 
The hog should, before being marketed, be well fattened, 
smooth and well rounded with a good outer covering of fat, and 
be firm and solid to the touch. If the feeder will go into a pen of 
thin hogs and feel them along the loin and back, and then into a 
pen of well fattened hogs, he can quickly learn the “feel” that in¬ 
dicates a good finish. The hogs should be sorted to an even size 
and weight before being shipped.
