196 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



4. " Gains made on forage are made at 20 to 30 per cent 

 less cost than gains produced with grain and dry lot feeding. 

 With pork at 6 cents, the average value of a bushel of corn 

 fed to hogs in dry lot was 66 cents ; and the average value of 

 a bushel of corn fed to hogs on forage was 80 cents, after a 

 $10.00 charge (per acre) had been paid for rent, taxes, etc." 



Fall Rye. Rye does not make so valuable a pasture as 

 many other crops, and its main feature is its early growth. 

 For supplying pasture very early in the spring, a small plot of 

 rye can often be used to good advantage. 



Cow-peas. The cow-pea flourishes in the South, where it 

 gives exceptionally good results as a hog pasture. (Fig. 45.) 

 It is frequently sown among corn with the last cultivation, and 

 pastured after the corn is harvested. The Mississippi Ex- 

 periment Station (Bulletin 100) reports producing from 350 

 to 483 pounds of pork from an acre of cow-peas. The peas 

 were allowed to become nearly ripe before the hogs were turned 

 in. (Also see Missouri results reported in this chapter.) 



Mixtures. Various mixtures have been used as pasture 

 crops for swine. The writer has used oats and peas, also a 

 mixture of oats, peas, and vetches. These crops do not stand 

 pasturing well, and are better suited for soiling purposes. 



The Michigan Experiment Station speaks well of a mixture 

 of corn, peas, oats, rape, and red clover. There is a good deal 

 of waste in pasturing this crop. If, however, the first crop 

 could be cut for soiling purposes, the second growth would 

 furnish a good deal of pasture. (See also Missouri tests re- 

 ported in this chapter.) 



Jerusalem Artichokes. The Central Experimental Farm, 

 Canada, reports good results from this crop. One-sixteenth of 

 an acre was planted on May 19th with 70 pounds of tubers. 

 The tubers were planted about four inches deep, in rows 24
