196 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



plement The pasture lasted from September 13th to October 

 25th, and the amount of pork per acre accredited to the forage 

 was 183.1 pounds. 



Hogging Off Rye. The authors state that when rye is in- 

 tended 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 pound's, 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 head 

 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 cents, the average value of a bushel of corn 

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