could be accredited to each acre of forage eaten. These experiments indicate that 

 a value of 98 cents ma}^ be obtained for each bushel of corn fed to hogs pasturing 

 on clover, when pork is worth 6 cents, and when rent of land, taxes, labor, etc., are 

 valued at $10.00 per acre." 



Rape, Oats and Clover. — This mixture was sown at the rate of 5 to 7 

 pounds of rape, i/2 bushel of oats, and 6 to 10 pounds of clover per acre. The 

 results are summarized as follows : " A herd averaging 10 hogs per acre was 

 pastured on rape, oats, and clover forage for an average of 96 days for the seasons 

 of 1909 and 1910, and produced an average of 391 pounds of pork that could be 

 accredited to each acre of forage eaten. A value of 89 cents may be obtained for 

 every bushel of corn fed to hogs on rape, oats, and clover forage when pork is worth 

 6 cents per pound, and when rent, labor, taxes, etc., are valued at $10.00 per acre." 



Hogging Of Bye. — The authors state that when rye is intended for 

 "hogging off" purposes it should be allowed to become thoroughly ripe, so that 

 the heads crinkle down and droop near the ground. In three tests a supplementary 

 ration of corn meal 6 parts and oil meal 1 part was fed at the rate of 1 pound per 

 head per day. In two tests 16 hogs were pastured per acre, and in one test 8 hogs 

 per acre. The amount of pork accredited to an acre of rye in the three tests was 

 215 pounds, 257 pounds, and 260 pounds respectively. With pork at 6 cents per 

 pound the returns are accounted about equal to the returns when the crop is sold 

 as grain but the fertility is retained under the pasturing system. 



General Conclusions. — Of the general conclusions given in the bulletin, 

 the following are of special importance : 



1. "The number of hogs which may be kept on each acre of forage will 

 depend upon the abundance of forage, but in general not more than 10 to 12 head 

 should be used." 



2. "The greatest returns have been obtained when grain was fed in addition 

 to the forage at the rate of 2 to 3 per cent, of the weight of the hogs per day. 

 The amount fed per liead per day should be increased as the hog increases in size." 



3. " A very good plan in feeding 80 to 100 pound hogs on forage would be to 

 feed, per head per day during May, 1.75 pounds of grain; during June, 2 pounds 

 grain ; during July, 3 pounds grain, and during August, 4 to 5 pounds grain." 



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 cento the average value 

 of a bushel of corn fed to hogs in dry lot was &Q cents ; and the average value of a 

 bushel of corn fed to hogs on forage was SO cents, after a $10.00 charge (per acre) 

 had been paid for rent, taxes, etc." 



Fall Rye. — Eye 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 oi rye can often be used to good advantage. 



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 test reported 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
