ANIMAL PRODUCTION. 569 



In the 3 lots fed coru meal alone, the average daily gain per head was 0.24, 

 0.27, and 0.2S lb., respectively, while the feed eaten per pound of gain ranged 

 on an average from 6.8 to 15 lbs., and the cost of a pound of gain fi'om 6.05 to 

 13.44 cts. 



Considering the tests in which corn meal was supplemented, the average 

 daily gain ranged from 0.65 lb. per head on corn meal and linseed meal about 

 5 : 1 to 1.43 lbs. on corn meal and skim milk. The amount of concentrated feed 

 eaten per pound of gain ranged from 3.1 lbs. with the 2 lots fed corn meal 

 and linseed meal to 6.1 lbs. on corn meal and middlings 2:1. On the rations 

 with supplementary feeds coru meal and middlings were most expensive, a 

 pound of gain costing 6.47 cts. The gain was most cheaply made with corn 

 meal and skim milk and corn meal and linseed meal, costing in each case 

 practically 3.2 cts. per pound. 



Of the 3 lots fed corn meal and skim milk 1 : 4, one had the run of a bare lot 

 and one of a grass lot, while the third was confined in a pen. The last-men- 

 tioned lot made the greatest gain, 1.43 lbs. per head per day, while the smallest 

 gain, 1.32 lbs. per head per day, was noted with the pigs in the bare lot. 



In one of the tests, red dog flour and corn meal were fed soaked and in the 

 other unsoaked. The gains in the 2 cases were, respectively, 1.28 and 0.89 lbs. 

 per head per day. 



Some of the general conclusions which were drawn from the test follow : 



" When either middlings or linseed meal was added to a ration of corn meal 

 in proportion to supply an equal relative amount of digestible protein, the 

 gains wex"e practically the same, and increased very markedly over those ob- 

 tained where corn meal alone was fed. . . . 



" It appears that it would not pay to feed more than 10 lbs. of meat meal per 

 90 lbs. of corn meal. 



" With hogs varying in age from 4 to 6 months, it appears that from 0.75 to 

 1 lit. of gain per head per day may be expected when corn meal and protein 

 amendments are fed, or from three to four times the gains obtained where 

 corn meal alone is fed. . . . 



" Hogs nine months of age made gains of 1.26 and 1.35 lbs. on corn meal and 

 middlings and shelled corn and middlings, respectively, as compared with gains 

 of 0.67 and 0.86 of a pound for five-months hogs fed on various rations of corn 

 meal and middlings. . . . 



" A good profit may be anticipated by the careful feeder of hogs on a mar- 

 gin of 50 cts., an excellent profit on a margin of $1, and large profits on 

 margins of $1.50 and $2. 



" These results show conclusively that it is false economy, and wrong theoret- 

 ically and practically, to attempt to maintain hogs on corn meal alone, and that 

 much larger and better gains will be secured by feeding the hog rationally and 

 in accordance with his natural requirements, as indicated by his origin, his 

 inherited qualities and natural instincts, and as shown by the investigations 

 of scientific workers in the fields of physiolog;^- and nutrition." 



Forage crops for hogs in Kansas and Oklahoma, C. E. Quinn ( U. <S?. Drpt. 

 Agr., Bur. Plant Iitdii!^. Bill. 111. pt. J/, iip. 2-'i). — On the basis of information 

 gathered from a number of successful swine growers in Kansas and Oklahoma, 

 pig raising for these regions is discussed. 



The importance of pasturage for pigs is every year becoming more recognized, 

 as the author points out, and in the opinion of 95 per cent of the farmers in- 

 terviewed no pasturage is better for pigs than alfalfa where it can be success- 

 fully grown. Wheat, oats, and rye have also proved important, while clover, 

 rape, sorghum, cowpeas, soy beans, grasses, root crops, and pumpkins are less
