116 EXPERIMENTS IN PIG FEEDING 



3 cents' worth of food to produce one pound of gain, and the 

 corn- bran ration cost over 4 cents per pound. The highest 

 cost to produce a pound of gain was in the apple-pumpkin 

 ration, where 4.64 cents of food was required to produce one 

 pound of gain. This was due to the price of apples. The 

 latter, even at the low price of 10 cents per bushel proved less 

 economical as a food for feeding these pigs than any of the 

 other rations, and Avhere they were used in connection with 

 pumpkins the average profit for the whole period was but 

 33 cents for each pig. 



All things considered, the lots fed pumpkins, either raw 

 or cooked, in connection with cornmeal, produced the greatest 

 profit, and at least cost for each pound gain, live weight. 



CO'NCLUSIONS FROM THIS EXPERIMEN^T. 



1. The cooking of pumpkins does not increase their feed- 

 ing value. 



2. When pumpkins are available for pig feeding they can 

 be fed most economically in connection with cornmeal. 



3. While raw pumpkins fed in connection with milk pro- 

 duced a pound of gain at small cost, so few pounds were pro- 

 puced it is advisable to fe_ed cornmeal with them. 



4. Apples, even at the low price of 10 cents per bushel, 

 are not an economical food for pigs. 



5. Bran is not desirable as a food for pigs, even if fed 

 with cornmeal. This is further considered in the following 

 experiment.

FEEDING VALUE OF BRAN", FERMENTED AND UNFERMENTED ; 

 BRAN AND CORNMEAL; CORNMEAL IN PIG FEEDING. 



This experiment also was conducted with pigs raised at 

 this station. The writer has been frequently told that some 

 farmers in the state are in the habit of fermenting and sour- 

 ing bran before feeding it to their pigs, holding that the best 

 gain is made by so doing. 



With this in mind, the writer outlined the following experi- 

 ment and fed four lots of pigs, three in a lot, for 120 days. 

 The pigs used were from a cross between Chester white sows 

 and Berkshire boar, and at the beginning of the experiment 

 weighed from 45 to 50 pounds each. 



The experiment was divided into two periods; the first 

 for 99 days, and the second 21 days. 



During the first period, — 



Lot A was fed fermented bran and milk. 



Lot B was fed unfermented bran and milk. 



Lot C was fed bran, cornmeal, and milk. 



Lot D was fed cornmeal and milk.
