Corn, wheat and soy-bean meal with skim milk for pork production, A. M. 

 SouLE and J. R. Fain ( Tentu'KSce Sta. liul. Vol. XVI, No. .i, pp. 33-48, Jigs. 5). — Two 

 tests, the first of (iO days' and the second of 77 days' duration, were undertaken for 

 the purpose of studying the value of corn meal alone and fed with different amounts 

 of skim milk, and also the effects of substituting wheat meal and soy-bean meal for 

 part of the corn meal when combined with skim milk. 



In the test made in 1892 each lot contained 3 grade Chester White pigs, while in 

 the test made in 1893 each lot contained 4 grade Berkshires. The rations fed and 

 the general exjierimental conditions were practically the same in the 2 tests, l(jts 

 1, 2, 3, 4, and 7 being fed corn meal and wheat meal, 2:1, with skim milk, the pro- 

 portion oi grain to milk ranging from 1:3 in the case of lot 1 to 1:12 in the case of 

 lot 4. In each case lot 5 was fed corn meal only; lot 6 corn meal and skim milk, 

 1:8; and lot 8, corn meal and soy-bean meal, 2:1, with skim milk in the proportion 

 of 1 part grain to 8 parts milk. 



The gains on corn meal, wheat meal, and skim milk in 1892 were practically uni- 

 form, being about 1.5 lbs. per head per day. With lot 8 (corn meal, soy-bean meal, 

 and skim milk) the average daily gain was 1.6 lbs. per head per day. Witli lot 5 

 (corn meal only) it w^as 0.9 lb., and with lot 6 (corn meal and skim milk) 1.7 lbs. 

 In 1903 the gains on corn meal, wheat meal, and skim milk ranged from 1 lb. per 

 head per day with lot 7 (grain and skim milk 1:8) to 1.3 lbs. with lot 3 (grain and 

 skim milk 1:9). With lot 6 (corn meal and skim milk) and with lot 8 (corn meal, 

 soy-bean meal and skim milk) the average daily gain in each case was 1 lb. jier head 

 per day, and with lot 5 (corn meal only) 0.24 lb. 



Considering the averages for the 2 years, the smallest gain, 0.5 lb. per head per day, 

 was made with lot 5 (corn meal only), and the greatest gain, 1.4 lbs., with lot 3 

 (grain and skim milk 1:9), and lot 4 (grain and skim milk 1:12). The largest amount 

 of grain per pound of gain, 4.1 lbs., was required on corn meal alone. When grain 

 was fed with skim milk the amount required per pound of gain ranged from 1.4 lbs. 

 with lot 4 (grain and skim milk 1:12) to 2.2 lbs. with lot 1 (grain and skim milk 

 1:3). In the latter case the smallest quantity of skim milk, 6.5 lbs., was required, 

 and in the former the greatest amount, 16.4 lbs. With lot 1 the gains were made 

 most economically, costing 4.4 cts. per pound, while with lot 5 the gain was most 

 expensive. The profit ranged from $3.38 per lot on soy beans to $7.63 per lot on grain 

 and skim milk 1 : 3. 



"The cost of soy beans in the case of the [former] group was jirobably responsible 

 for the small profit shown, which indicates the importance of studying and utilizing 

 those grains best adapted for the cheap production of pork." 



At the conclusion of the test the pigs were slaughtered, the weight of the carcass 

 and other data being recorded for lots 5 to 8 in the first test and for all the lots in the 

 second test. 



"The best slaughter tests were made by the hogs receiving corn meal, wheat meal, 

 and skim milk, there being little choice between the 4 groups; while those receiving 

 corn meal and soy-bean meal were somewhat lower. That these hogs were not so 

 profitable as those of higher grade is shown by the fact that certain well-bred animals, 

 reared and fed on the University farm, sold and slaughtered at the same time, dressed 

 from 81 to 83 per cent, a difference of from 2 to 10 ])er cent in favor of the better-bred 

 hogs. ' ' 



Peptone feed tested with pigs, W. Muller {Fiddhiy's Landw. Ztg., 5,i {1903), 

 No. 17, pp. 597-604, dgm. l). — Using 4 lots of 4 pigs each, the value of a so-called 

 peptone feed, with or without meal, was compared with meal alone and with bran 

 and a molasses mixture, potatoes forming a i)art of the ration in all cases. The pep-
