mum deviations by weeks. The ration was gradually widened as the feeding 

 period progressed, thus confirming a statement of Lawes and Gilbert made in 

 is:, I. 



At the close of the test Nos. 13 and 14 were excessively fat and appeared soft. 

 No. -1 finished in show yard bloom. The carcasses showed the pigs to be very 

 fat, but the fat was well distributed throughout the lean. The hams and shoul- 

 ders when cured proved to be of excellent flavor. The sides were too heavy 

 for prime commercial bacon. 



Studies with individual pigs {Minnesota Sta. Rpt. 1918, pp. 51-5S). — A con- 

 tinuation of the work outlined in the above paper during 1917 is noted. Sixteen 

 pure-bred pigs were fed. A tabulation is made for each individual of this and 

 the preceding experiment of the grain consumption per 100 lbs. gain and his 

 deviation from the average of the lot to which he belonged. 



Pasture and forage crops for pork production (Minnesota Sta. Rpt. 191R, 

 pp. 49-51). — Results with 4 lots of pigs on alfalfa and rape pastures are sum- 

 marized as follows: 



Growth of shotes on pastures supplemented with corn, and corn and tankaf/e. 



In contrast unsatisfactory results are cited with 10 pigs on oats, peas, and 

 rape. The animals became severely rape blistered at the start, and gained 

 only 821 lbs. per acre in 9S days, or 0.35 lb. daily per pig. 



Results from 4 cooperative tests of pastures for swine are given. The pas- 

 tures are described as (1) rye and rape (poor), (2) clover (good), (3) mixed, 

 and (4) alfalfa (good). The grain fed per pound of gain was 5.46, 4.03. 5.58, 

 and 4.52 lbs., respectively, and the margin of value of gain (at 16 cts. per 

 pound, over total feed cost was .$0.22, $4.26, $2.26, and $1.25, respectively. 



In 2 experiments in hogging-off corn the number of hogs per acre was. re- 

 spectively, 25 and 24, the gains per acre 315 and 5S2.6 lbs., the estimated con- 

 sumption of corn per pound of gain 10.52 and 5.83 lbs., and the tankage fed 

 per acre 114 and 76 lbs. It is stated that the first lot remained on the cornfield 

 at least 2 days too long. 



Feeding tests with fall pigs, 10 to a lot. 4 lots fed 105 days and 3, 155 days 

 from weaning to market are also noted. One was hand fed by the Dietrich 

 standard, the others self fed on corn mill feed, shorts, and tankage, either with 

 or without additional feed. For the lots fed the shorter period the additional 

 feeds, in the order of their apparent feeding value as measured by daily gain, 

 were (1) shelled corn and gluten feed, (2) condemned raisins, (31 none, and 

 (4) corn gluten feed. For the longer period, the order was (1) alfalfa, and 

 (2) none, with the hand-fed lot intermediate. 



Feeding value of field peas v. barley (Washington Sta. Bui, 153 (11 

 pp. 8, 9). — In this experiment 4 lots of shotes of Duroc-Jersey. Poland China, 

 and Berkshire breeding were fed 40 days in January and February. 1918, 

 under weather conditions not favorable to feeding operations. Comparison was
