and hence nature, soon turned awry, protests against this food by showing poor 

 appetites, lack of gain, and other evidences of unthrift and malnutrition. . . . 



"The results plainly show that corn, either ground or whole, should not be used 

 exclusively with pigs or young hogs. So far as they are of any value otherwise, 

 they show a positive disadvantage following the grinding of the corn to meal. So 

 disastrous were the results that it is doubtful if we are warranted in continuing such 

 experiments with pigs." 



Some effects of feeding wide and narrow rations on the growth of young 

 pigs, J. G. Fuller ( Wisconsin Sta. Rpt. 1904, pp. 25-31, figs. 2). — Using 2 lots of 3 

 young pigs each, the feeding value of corn meal, mixed to a thick slop with water, 

 and corn meal and wheat middlings 1:1, mixed with skim milk, was studied, the 

 trial covering 110 days. 



The total gain on corn meal was 130 Lbs., the dry matter required per pound of 

 gain 7.12 lbs., and the net profit 49 cts. On corn meal and middlings the total gain 

 was 362 lbs., the dry matter eaten per pound of gain 3.33 lbs., and the net profit$5.90. 

 Slaughter tests were made at the conclusion of the trial and also a careful dissection 

 of the carcass and tests of the strength of hone with 1 pig from each lot. In the case 

 of the corn-fed pigs the dressed weight was 72 per cent of the live weight and in the 

 case of those fed a mixed ration it was 76 per cent. 



The author states that the lean meat of the pigs fed the mixed ration was notice- 

 ably darker in color and showed better marbling than in the case of the pigs fed 

 entirely on corn. On an average the thigh bones of the lot fed the mixed ration 

 were 50 per cent stronger than of those fed the corn ration. 



The author concludes that the constitution of all pigs fed corn only was seriously 

 impaired and that it is impracticable to raise young pigs on an exclusive corn ration. 

 "The feeding trial made dwarfed animals out of every pig in lot 1, fed exclusively 

 on corn. While they gained some in flesh they did not develop in bone, and, as time 

 went on, their vitality decreased. The hair on their bodies became thin and their 

 skin hard and scaly. Toward the end of the trial they were indifferent about eating 

 and showed considerable uneasiness." 



Soy beans v. middlings as a supplement to corn meal for fattening pigs, 

 (i. C. Humphrey ( Wisconsin Sta. Rpt. 1904, pp- 32-40, figs. 4). — Corn alone having 

 proved unsatisfactory for pigs, the relative value of soy beans and middlings as a 

 supplement to this grain was studied with 6 Improved Yorkshire pigs divided into 2 

 uniform lots of 3 animals each. The difficulty experienced in grinding the soy beans 

 alone, the author states, was readily obviated when the beans and corn were mixed 

 before grinding. 



On corn and soy beans 2:1, the average daily gain per pig was 1.26 lbs. and the 

 feed required per pound of gain 5.39 lbs., as compared with 1.08 lbs. and 6.08 lbs. on 

 corn meal and middlings 2:1. At the close of the trial the pigs were slaughtered 

 and the live and dressed weight, weight of the organs, etc., recorded. The dressed 

 weight averaged 82 per cent on soy beans and 83.2 per cent on middlings. No 

 marked differences were observed in the distribution of fat and lean on the carcasses, 

 yet the authi >r states that there was a slightly better development of lean meat in the 

 case of the pigs fed the soy beans. 



" No definite conclusions can be drawn from this single trial, and results of further 

 trials will he sought with interest." 



Pig- feeding experiment, A. (Joss [Indiana Xiu. A'/''- 1904, pp. 0,7). — A brief 

 account is given of a feeding test with 4 lots of 4 pigs each. On corn only there was 

 a total gain of L83 lbs. at a loss of :; cts.; on corn and shorts 1:1 the total gain was 

 365 lbs. with a profit of $5.71; on corn and soy beans 2:1 the corresponding values 

 were 402 lbs. and ^M, and on corn and tankage 5:1 they were 348 lbs. and $4.49. 



"It will be seen that the lot fed with corn and soy beans made considerably over 

 double the gain in live weight made by the animals fed on corn alone, and the lots
