cent (in each plat. The spring growth of grass was also considerably 

 behind the alfalfa, being, on May 28, only 8 inches high and very 

 sickly looking. 



On this date two grade Poland China pigs were placed on each 

 brome-grass plat; This breed was used in place of Duroc-Jersey 

 because of the scarcity of fall pigs of the latter breed. 



The number of animals used was not sufficient to keep down the 

 growth of vegetation, and both plats were soon covered with a rank 

 growth of weeds. Both plats were mowed to control the weeds. 

 The pigs were removed from both pastures on July 9. 



The hogs on the row plat, starting with an initial weight of 170 

 pounds, gained 50 pounds during the 42 days on pasture, an average 

 of 0.0 of a pound each per day. They received 166 pounds of corn, 

 or 3.32 pounds of corn for each pound of gain. 



The lot on the broadcast plat weighed 169 pounds to start with and 

 gained 76 pounds, or 0.9 of a pound a day for each animal. During 

 the 42 days on pasture 169 pounds of corn were fed. This was equal 

 to 2.22 pounds of corn for each pound of gain. 



The check plat of broadcasted brome-grass yielded 568 pounds of 

 weedv hay. 



RESULTS IN 1921. 



RYE. 



Winter rye in the pasture experiment did not come up until April 20 

 and was not ready for grazing until June 9. The forage was about 10 

 inches high and thinly scattered over the plat. The estimated stand 

 was 50 per cent. 



Ten pigs having a weight of 1,262 pounds were placed on the plat 

 on June 9 and remained there until July 14, a period of 35 days. 

 Owing to the thin stand of rye and the droughty conditions during 

 the season, the 10 pigs had little difficulty in controlling the forage 

 over the entire acre. 



A gain of 286 pounds was recorded for the lot, or a daily gain of 

 0.82 of a pound per pig. The corn fed totaled 984 pounds, or 3.44 

 pounds of corn for each pound of gain. 



The yield of the check plat of rye was somewhat reduced by a 

 hailstorm on May 31, but it yielded 5 bushels per acre when thrashed. 



PEAS. 



The crop of peas was destroyed by hail on May 31, and no results 

 were obtained either by pasturing or by harvesting with machinery. 



BARLEY. 



The lateness of the rye-pasturing season and the loss of the pea 

 crop necessitated moving the 10 pigs directly from the rye to the 

 barley plat. The barley had been somewhat injured by hail on May 

 31, but the crop had made considerable growth before the pigs were 

 turned onto it on July 14. The grain was in the soft-dough stage 

 and because of drought was maturing rapidly. 



Though the pigs consumed all the grain on -the plat with apparent 

 relish, the light yield and poor quality resulted in only small gains. 



The pigs were removed on July 28, after a pasture period of 14 

 days. A gain of 21 pounds was made by the lot, each pig averaging 

 only 0.15 of a pound per day. 



The check plat of barley yielded 6.4 bushels per acre of thrashed 

 grain of poor quality.
