dncing 100 lbs. of piin was $2.18. Lot 2 c;oiisumed 12.4 lbs. of 

 potatoes and 2.8 lbs. of shorts daily and gained 1.3 lbs. This was 0.5 

 lb. less than the gains made by lot 1. The cost of 100 lbs. of gain was 

 $2.80. 



The following conclnsions were reached: Uoth lots made good gains 

 and were well matured. The ])igs would not eat a larger ration of 

 potatoes than was given them. To obtain the best results the amount 

 of potatoes should have been decreased and more grain fed. The 

 tiiiancial returns from the grain ration were better than from the ration 

 of potatoes and grain. A mixture of grain fed with potatoes is better 

 than shorts alone. Potatoes and other vegetables, cabbages, squashes, 

 and pumpkins should be cooked before being fed. Although pigs may 

 eat them raw, they are not eaten with relish. 



Swine feeding, C. D. Smith [Michigan 8ta. Rpt. 189',, pp. 134-142). — 

 A number of experiments to test different feeding stuft's for pigs are 

 reported. In February, 1894, an experiment was made to test the value 

 of skim milk and to compare wheat with corn. Twenty grade Poland 

 China pigs, divided into 4 lots of 5 each, and one lot of 3 [)ure bred 

 Essex barrows were used. The test lasted 6 weeks, except with lot 3, 

 which was discontinued after 25 days, owing to the illness of one of 

 the pigs. 



Lots 1 and 3 were fed corn meal, lots 2 and 4 wheat meal, an<l lot 5, 

 corn meal and wheat meal in equal quantities. All the lots were fed 

 skim milk in addition. The financial statement is based on corn meal 

 at $16 and wheat meal at $20 per ton. The results are given in the 

 following table:

Twentj'-flve days only. 



The pigs were sold for $4.25 per 100 lbs. The total gain was $02.39. 

 Taking from this the cost of the grain, the value of the skim milk is 

 28.4 cts. per 100 lbs. 



The following conclusions were reached: The larger pigs in lot 5 

 required considerably more dry matter per pound of gain than the 

 smaller pigs. Wheat compared favorably with corn as a food for 

 young and growing pigs. Its economical use would depend <)n its price 

 in comparison with corn.
