ANIMAL 'PRODUCTION. 1075 



HXKl. lip. l,S-32)> — Conliiiuiiiu' cirlicr work ( K. S. K., IS. p. '2i\C,), 3 tests are 

 rejiorted. 



In the first, corn (Itotli whole ami l'i-ouikI ) and wheat iiii(l(lliii!.;s I :l with 1' 

 Ihs. of skim milk iK>r head daily were U'il. The total .train in TJ weeks made hy 

 the V2 pigs fed the wliole-eorn ration was ].'2i)'i lbs. and h.v tlie similar lot I'-ij 

 the ^round-forn ration, 1,L'!)S Ihs. The 1' lots reiiuired ."i.tiU .-md :).(>() lbs. of 

 irrain ;ind L(it! and l.~A lbs. of skim milk per pound of gain, respectively. In 

 the second test corn (whole and ground) and wheat nuddlings 2:1 without skim 

 milk were fed for 12 weeks to 2 lots of 5 i)igs each. On the whole-corn ration 

 tlie total gain was 54!) lbs. and the grain eaten per pound of gain 4.71 lbs. 

 Similar values for the lot fed the a)rii-meal ration were 701 lbs. and 4.42 lbs. 

 In the third trial the slielltnl corn and corn m(\-il. supplemented in each ease by 

 wheat middlings, were compared with 2 lots of (5 pigs each, pastured on raiie. 

 < hi the wliole-corn ration the total gain was 741 lbs. and on the eorn-uieal ration 

 '.xi'.t lbs., the grain eatc-n per pound of gain being 4.00 and 3.09 lbs., respectively. 



t'onsiderhig the in years tests as u whole, the average gain on whole corn 

 has been 7(;.S lbs. per lot of 8 pigs, and on corn meal 883 lbs., the feed eaten 

 lier pound of gain in the 2 cases being 5.01 and 4.71 lbs., or an economy of G 

 per cent in favor of the ground grain. 



"Where there is plenty of time for maturing the pigs, and it is not necessary 

 to secure the maximum daily gain, it is doubtful if it pays to grind corn for 

 pigs. The test shows that where quick maturity is an important item better 

 results are secured from the corn meal. Pigs fed corn meal eat more grain .-md 

 make somewhat larger daily gains. Corn meal can doubtless be used to good 

 advantage in finishing off a bunch of hogs which were first fed shelled corn. 

 Changing over to corn meal near the close of the feeding period also furnishes 

 a change in the character of the ration which will be satisfactory to the animals. 



"There are conditions and circumstances where it is not advisable to grind 

 the corn even though the corn be high priced. On the other hand, when fitting 

 hogs for show, sale, or in high-pressure feeding for market, the feeder will 

 consider it advisable to grind the corn, even though it is expensive to do so. 

 The feeder, knowing these results, will use them to suit his own conditions." 



Soy-bean meal versus wheat middlings as a supplement to corn meal for 

 growing and fattening pigs, G. C. Humphrey and J. G. Fuller ( Wisconsin 

 ^7a. Ri)t. 1U06, pp. 33--'il, fig. 1). — When corn meal and soy-bean meal 2:1 were 

 compared with a like proportion of corn meal and wheat bran with 2 lots of 5 

 pigs on rape pasture, the average daily gain in 12 weeks on the soy-bean-meal 

 i-ation was 0.7.", ih. ]ier head and on the wheat-middlings ration 0.73 lb. Skim 

 milk was fed with tlie grain and in the last half of the period was mixed with 

 it in equal amounts to form a thick slop. The 2 lots consumed per pound of 

 gain 3.0(! and :i.05 lbs. grain and 3.34 and 3.35 lbs. skim milk, respectively, 

 (|uantities which are practically the same. The pigs were then taken off the 

 pasture and given the same grain and skim-milk rations in i)ens for 12 weeks. 

 The average dail.v gain on the so.v-bean-meal ration was 1..32 lbs., and 3.57 lbs. 

 ciich of grain and skim milk was consumed ]ier pound of gain. With the lot 

 fed wheat middlings the average daily gain was 1.23 lbs. i»er head, 3.S5 lbs. of 

 both skim milk and grain being consumed per pound of gain. As shown by a 

 slaughter test, there was practically no difference in the percentage of dressed 

 weight for the 2 lots. The kidne.v fat in the lot fed the so.v-bean ration con- 

 stituted 3.3 per cent of the total carcass and in the wheat middlings lot 2.'.i jier 

 cent. The feeding stuffs used were analyzed. 



"Soy-bean m(>al mixed with corn meal in the proportion of 1 : 2 i)roduces 

 greater gains than wheat middlings and corn meal fed in the same proportion.
