The value of recleaned screenings, W. C. McKillican (Saskatchetvan 

 Farmer, 9 (1919), No. 6, p. 17). — This is a report from the Brandon, Man., 

 Experimental Farm of the results of a 49-day comparison between barley chop 

 and recleaned screenings for feeding 125-Ib. shotes. The screenings were of 

 the sort formerly known as " grade A," and now called " standard stock food." 

 They consisted chiefly of broken and shrunken wheat and wild buckwheat, with 

 small amounts of oats and flaxseed. 



The tests began December 3, 1918, and 12 lots of 10 hogs each were employed, 

 each grain mixture tested being fed to 2 lots. A small amount of tankage was 

 fed to each lot, and the grain mixtures were given according to appetite. The 

 amounts of the respective grain mixtures consumed per pound of gain were as 

 follows : Barley alone, 4.53 lbs. ; screenings alone, 4.43 lbs. ; barley and red dog 

 (3:1), 4.32 lbs.; screenings and red dog (3:1), 4.51 lbs.; barley and shorts 

 (3:1), 4.54 lbs; and screenings and shorts (3:1), 4.66 lbs. The gains were 

 quite uniform from lot to lot, and it is concluded that the screenings were fully 

 equal to barley for finishing hogs. 



. Barley v. corn for breeding gilts, J. M. Evvaed and R. Dunn (Swine 

 World, 8 (1920), No. S, pp. 26, 27; also in Duroc Bui. and Live Stock Farmer, 

 16 (1920), No. 20, pp. 50, 52).— Five lots of 130-lb. pregnant gilts were fed for 

 about five months at the Iowa Experiment Station beginning November 14, 1918. 

 The check lot received shelled corn (averaging 3.68 lbs. per head daily), tank- 

 age (0.2 lb.), and ground alfalfa (0.2 lb.), and made a daily gain of 0.77 lb. per 

 head. Barley prepared in one of four ways replaced the corn in the rations of 

 the other lots, the amount of barley being adjusted to secure, so far as possible, 

 the same gain as the check lot. From the feed consumption and gains it was 

 computed that for wintering gilts 1 lb. of corn is equal in value to 1.05 lbs. 

 dry ground barley, 1.13 lbs. soaked ground barley, 1.24 lbs, dry whole barley, 

 or 1.25 lbs. soaked whole barley. 



Barley for fattening pigs, F. B. Morrison and G. Bohstedt (Wis. Farmers' 

 Insts. Bui. 32 (1919), pp. 96-103, figs. 2; also in Hoard's Dairyman, 57 (1919), 

 No. 15, pp. 773, 776, figs. 3). — A feeding exberiment with 10 lots of hogs averag- 

 ing 128.8 lbs. in weight was begun at the Wisconsin Experiment Station Feb- 

 ruary 14, 1919. Lot 1 consisted of 10 shotes, the» others of 5. The feeding 

 methods compared and the main results are indicated in the following table :
