of .'! Il>s. "The alfalfa rations t'<>r young growing pigs were lamentable failures. 

 The pigs grew scrawny and lost weight." 



Supplements to corn for fattening- hog-s, I . B. Forbes M ri Sta. /.'"/. /;;, 



pp. an. Using 15 lots of 1 or 5 pigs each concentrated feeds in varying proportions 

 ami combinations were compared as supplements to corn meal for dry-lol fattening. 

 Ear corn was also compared with corn hum I. both being fed w it li linseed oil cake. 



The tests were made in the winter and covered 29 to 90 days, being preceded by 

 preliminary periods of I to 6 weeks. The pL r > were confined in -mull pens with a 

 shed, but were not protected from wind and cold. The grains were ground and 

 mixed to a slop with water except in the comparison "i' ear corn and ground corn. 



When com meal was supplemented by wheal middlings and linseed men I with and 

 without germ <>il meal ami gluten meal and feed for 90 days, the _r .- § i r i ranged from 

 0.971 11). per head per day on corn meal and wheal middlings 2:1 t" l 430 lbs. on 

 corn meal ami linseed meal 5:1, and the grain eaten per pound "t" '_ r ain from 4. 15 II'-. 

 <>n the latter ration to 5.18 lbs. on the former. 



When linseed meal and wheal middlings were compared in varying propor ions as 

 supplements to corn meal in short periods (29 to 15 days) both the smallest and 

 greatest ga ins, L. 269 and 1.77<>ll»s. per head per day, were noted with l<>t- fed corn 

 meal ami linseed meal 5:1. The grain required per pound of gain was leasl with 

 one of these lots being 3.85 lbs. and greatest, 1.75 lbs., with a l>>t led corn meal and 

 wheat middlings 2:1. 



"The rations <»f linseed nil meal and corn meal in proportion of i : ;. were eaten in 

 larger quantity than any other iml- tested and made more pork with smaller 

 expenditure of feed than any other ration involved." 



The estimated cost of pork made from the oil-meal rations averaged 1 1.3 per cent 

 less than from the rations of corn meal and w heat middlings. 



"Of the three corn products, gluten feed, gluten meal and germ oil meal, the first 



mentioned seems to he more useful than the others when \i-<\ with corn ami linseed 

 oil meal. None of them, however, in this combination are a- useful as linseed 

 oil meal by itself. 



•• I iluten meal is richer than gluten irv<\, differing from it only in lacking the corn 

 bran with which it is ground to make the latter, hut it doe- qoI seem to he a- useful 

 a supplement to corn and oil meal. The ration containing it was not bo well relished 

 and was not so efficient. It is possible that the usual recommendation that gluten 

 meal be soaked before feeding to hogs would, if followed, have rendered it more 

 valuable in comparison with gluten irv>\ than it was in this experiment where it was 

 fed immediately after wetting." 



In 3 of the tests a mixture of corn meal and cotton-seed meal 8:1 was t'd for 6l 

 day*. Cotton-seed meal fresh from the Eactorj was fermented at living room tem- 

 perature for 24 hours previous to feeding, sour milk being used a- a -tarter. It wa- 

 in. ped that this fermentation would render the meal l«— toxic than it is reputed to 

 be. The cotton-seed meal ration was mixed to a thinner slop than the other rations 

 as it has been claimed that this is a desirable practice. The average daily gain per 

 pig was 0.966 lb. and the grain eaten per pound of gain 1.97 lbs. Three of the 15 

 pigs included in these tests died at the end of the feeding period. "The gains up to 

 that time had been moderate in extent and cost. The hogs did not relish this bed. 

 A change to the com and linseed oil meal ration induced much greater consumption of 

 grain, increased the gains in weighl 39 percent and reduced the -rain requirement 

 per pound of increase to the extent of 13.1 percent." 



When ear com and linseed cake 6:1 were compared with corn meal and linseed 

 cake 5:1, the average daily gain per pig on ear corn during the 6] days of the test 

 was 1.004 lbs. and the -rain eaten per pound of gain 6.65 II'-. Similar values for the 

 corn meal ration were L.291 lbs. and 6.05 lbs.
