ANIMAL PRODUCTION. 85 



"64.3 lbs. of apples will not only maintain a matured hog in good condition, but 

 enable it to add 1 lb. to its live weight. The experiment also indicates that a ration 

 of 1 lb. of crushed wheat, 2 lbs. of skim milk, and 6.66 lbs. of clover silage fed to 

 a brood sow weighing 300 His. or over will keep her in good condition when not 

 suckling pigs." 



The value of clover pasture for growing pigs was tested with 12 animals about 3 

 months old, hurdled on 26 sq. rods of good clover pasturage. In 3 months there w as 

 a total gain of 253 lbs. According to the author, "one acre of good clover for grow- 

 ing hogs represents a value of §44.36." 



As regards the value of rape, 10 young pigs gained 154 lbs. when turned on an acre 

 of June sown rape for 42 days and kept in a thriving healthy condition, although 

 they received no other feed. 



A thrifty barrow fed, in a pen, rape, vetch, skim milk, and a little grain gained 184 

 lbs. in TOdays, requiring 3.19 lbs. of crushed wheat and 1.52 lbs. of skim milk in 

 addition to the green feed for a pound of gain. 



The value of soiling matured pigs was studied with a lot of 4. In 1 month they 

 made a total gain of 25 lbs., requiring 85. 48 lbs. of green feed and 1.36 lbs. of mixed 

 grain per pound of gain. The soiling crops fed were rape, crimson clover, and alfalfa. 

 During the next month they were fed green alfalfa only and made a total gain of 5 

 lhs., requiring 328.4 lbs. of the green feed to produce a pound of gain. In the author's 

 opinion better results would have been obtained had the pigs been pastured on 

 alfalfa. 



In a second test 16 young pigs were fed from May 1 to June 2 crimson clover and 

 alfalfa, with skim milk and crushed wheat. The total gain made was 221 lbs. and 

 the feed required per pound of gain 15.85 lhs. skim milk, 7.66 lbs. of the soiling crop, 

 and 0.34 lb. grain. 



Supplementing a ration of green feed and skim milk with grain was studied with 2 

 lots of 8 pigs each. On alfalfa and skim milk the total gain made in 30 days was 130 

 II is. On skim milk and alfalfa supplemented by crushed wheat the total gain was 125 

 lbs. The lot fed the grain was somewhat superior to the other lot as regards appear- 

 ance and this, in the author's opinion, constituted the only advantage of the grain 

 ration. 



The feeding value of a mixture of peas and barley was tested with 3 pigs for a 

 period covering 92 days, "which is about 30 days longer than is usually advisable 

 to feed for economical results." The total gain made was 475 lbs., 7.1 lbs. of grain 

 being required per pound of gain. 



Six tests with an aggregate of 28 pigs of mixed breeding and various ages are 

 reported in which wheat, whole and ground, alone and as part of a mixed ration, 

 was studied, as well as the comparative value of wheat, peas, corn, barley, and barley 

 and potatoes. Skim milk was also fed in some cases. 



According to the author the best results were obtained with wheat, 4.48 lbs. being 

 required on an average to produce a pound of gain. In the first half of the fattening 

 period 3.81 lbs. was required per pound of gain, as compared with 5.12 lbs. in the 

 last half. In other words, "the heavily larded hog resultant from a long period of 

 feeding is much more costly to produce than the block hog, or the bacon type. . . . 

 Results also indicate that a bushel of wheat properly fed to reasonably well-bred 

 hogs should produce approximately 13.5 lbs. of live pork." 



Tests on the comparative value of boiled clover hay and clover silage and cooked 

 and uncooked grain have been noted from another publication (E. S. R., 13, p. 680).
