"Perliiips tlic price of wholr corn is too liigli, as it costs considcrahlo 

 to «'(nivert it into meal, but allowing one scvcuth for toll the bulauceis 

 still nmch in tavor of the meal-fed lot." 



I'm; ]-'ki;i)1.\<;, D.O. Norusi;, 15. S. (i»i». 1 1-27, plates (I). — This (;xi»eii- 

 nicnt was intendcil to ^cl additional inroiination as to tlieetlect of higldy 

 «-iirl)onaceous ;nid of liigldv nidogeuous rations on tlie dcvcbtpMient of 

 fill ;ind lean meat in pigs. 



Nine pigs were .select«'d for llie trial, six of wliicli were IJerksiiiie 

 harrows, about 5 months old at the begiuning of the trial, and the remain- 

 ing three a cross of Poland China aud Jersey Red, which had been at 

 piistnre and *•' were the largest lean hogs, even in size and (pnility, we 

 could procure"; they were from 7 to mouths older than the lierk- 

 shires. The pigs were divided into three lots of as nearly equal weight 

 :is possible, each h>t containing two Berk.shires and one of the older 

 hogs. Each lot received a dilfereiit ration, as foUows: 



Lot 1, corn meal alone; uutritive ratio 1 : 9 .0.5. 



Lot 2, 10 parts corn meal, 4 of bran, and 1 of beef scrap; nutritive ratio 1:5.82. 



Lot 3, 5 parts corn meal, 2 of bran, and 2 of beef scrap; nutritive ratio 1:2.3.5. 



Each pig was fed twice daily in a pen by itself, only as much food 

 being given as would be consumed without waste. Ashes, charcoal, 

 and salt were gi\en, but lutt mixed with the food. The animals were 

 weighed at the eiul of each week, before feeding. 



The experiment was commenced August 19; October IG two of the 

 ])igs in lot 3 died, and October 31 the third one died. An examination 

 showed that "death was probably caused by lack of power to assimi- 

 late the food." The feeding of lots 1 and L* was continued until Xovem- 

 bei- lio, when they were slaughtered. 



Seven tables give the weights of the animals, food <'onsumed, dry 

 substance consumed per 10(» pounds live weight and per pound of 

 increase, co.st of food per pound of gain, data obtained at time of 

 slaughtering, etc. ; and six jdates show cross sections of the carcass of 

 each pig. There was no perceptible ditVerence in the ]n'0|)ortion of fat 

 and lean meat in the hogs of the ditferent lots. The cost of the rations 

 is based on corn meal at $20, bran at $20, cotton-seed meal at $25, and 

 beef scrap at $-iO ]>er ton, making no allowance for the value of the 

 manure. The gains aud cost per pound of gain for lots 1 and 2 were as 

 follows :
