EXPEKIMENT STATION RECORD. 



quart of skim milk until they were taking 6 qt. of skim milk, wlien the 

 additional food required consisted of a mixture of equal parts of corn 

 meal and wheat bran until they weighed 200 lbs., when they were 

 finished off on skim milk and corn meal. Lot 2 was fed on skim milk 

 alone until they took 9 qt. per day, when an ounce of corn meal per 

 quart of skim milk was added until 12 qt. was being taken, when the 

 corn meal was doubled until the pigs weighed 150 lbs. each; they were 

 then given all they would eat of the corn meal and wheat bran mixed, 

 and were finished off in the same manner as lot 1. Soon after the 

 beginning of the experiment the 2 Small Yorkshires in lot 1 died. 



The data for the experiment, including the gains in live weight by 

 periods, the amounts of food and of dry matter eaten, financial results, 

 and the loss on dressing, are tabulated. The financial results are based 

 on dressed pork at 7 cts. per pound, corn meal at $21 and bran at $17 

 per ton, and skim milk at 15 cts. per 100 lbs. 



A summary is given in the following table: 



Summary of results of pig feeding trial. 



"The Chester Whites of lot 2, whose ration was narrower than those of lot 1 — 



"(1) Gained faster, 



" (2) Reached a greater live weight, 



"(3) Shrank the same, and 



"(4) Ate less dry matter to make a pound of live or dressed weight than did the 

 pigs whose food from the beginning was bulkier. Chester White No. 2 of lot 2, how- 

 ever, weighed no more at slaughter than did the Chester Whites of lot 1, notwith- 

 standing it had eaten 75 lbs. more dry matter. This makes the cost of the food of 

 this pig so high and so reduces the profits that the total profit ])er pig for the 2 lots 

 is nearly the same. . . . 



"The Small Yorkshires grew slowly. . . . They gained less in more time, ate more 

 dry matter to the pound of gain in live or dressed weight, and their food cost more 

 per pound of increase of dressed weight than that fed the Chester Whites. . . . 

 They were kept at a profit, yet the money gain from 7^ months of feeding was but 

 little more than one half that derived from a month's less feeding with the larger 

 breed. . . . 



''If the manure is considered to offset the care and the cost of gain is subtracted 

 from the price obtained for dressed pork, the skim milk may be considered to have 

 brought 25 cts. per 100 lbs. The fertilizing value of the food was 58 per cent of its 

 market value." 



Proper amount of sMm milhfor finishing off (p. 37). — From October 11 

 to December 10 lot 1 received 366 qt. of skim milk and 374 lbs. of corn 

 meal each, and the Chester Whites in lot 2 received 732 qt. of skim 

 milk and 339 lbs. of corn meal each.
