 Ifom (lie same litters as those of Lots o ami t, ami were fed sUim-milk 

 ami eornmeal as a check ration. Their daily «i;ains were one-third of a 

 ponnd more and at the close of the feedin«»; ])eriod they averaji;ed 25 

 pounds more per ])i<;- than those fed on cornnu'al and beans. 



Trials 5 (///(/ G. — From daily observation of each of the four lots \shieh 

 were fed on beans and eornmeal, it was apparent that the food com- 

 bination, wliile it possessed the proper amounts of carbohydrates and 

 l)rotein, was not well enonjih adapted to the requirements of the ]»i<>s 

 to produce adequate growth. Jt was tlioujiht that the introduction of 

 a less concentrated food factor would give variety to the ration, and at 

 least a physical composition better suited to tlie age and digestive low- 

 ers of the i)igs. Accordingly middlings was substituted for a part of 

 the beans used. 



The trials were conducted during the winter and spring of 1JK)(», be- 

 ginning January 2o, l!)t)(>. and closing April ,'{, IDOG. 



lid t ions. — The rations of both lots were the same, and were made up 

 of eornmeal three ]»arts, middlings two })arts, and cull beans two 

 pai'ts. The method of prei)aralion was the same as that described in 

 Trials 1 to 4. 



l'i(/s Iscil. — lOach lot was made uj) of two ])ure bred llerkshires. 

 anil three ])ure bred Yorkshires, the average wi'ight of the ten pigs at 

 date of starting the experiment being To pounds. The feeding jjcriod 

 was ten weeks or seventy days. The following table sets forth the 

 main portions of the data: 



Table 11. 



From the above it will be observed that the daily gains ])er head range 

 between 1..'>LI pounds and l.'A'y pounds, the average for all being apiu'oxi- 

 mately li/^ pounds. Also, following the schedule of in-ices previously 

 given, that the cost per hundredweight of gain ranges from |3.0() to 

 13.11); the average for both lots being |3.0i)." 



While the gains obtained with the above food combination were 

 not exceedingly large, they were sufticient, in view of the restraints 

 generally necessary with experimental pigs, to be called quite satis- 

 factory. The cost of production is also quite reasonable. If the reader 

 wishes to compare these results Mitli those obtained from the use of 

 eornmeal and beans in Lots 1 to 4 inclusive, he might assume that the 

 ]iigs were worth 5 cents per jionnd live weight at the close of each experi- 

 ment; as a matter of fact they were worth more than that. The first four 

 lots produced 1,118.(5 pounds gain at a food cost of 2.8 cents per pound.
