134 HARRIS ON THE PIG. 



only T\ t Ibs. of codfish each, per week, and gained 

 8.94 Ibs. 



It will be seen that, when left to their own choice, the 

 pigs in pen 3 ate only about half as much codfish as those 

 in pens 1 and 2, where their other food was kept back 

 until they had eaten their allowance of 2 Ibs. of codfish 

 per day. 



The above pigs were about nine or ten months old, and 

 were similar in character, weight, etc., to the pigs in the 

 first two Series of experiments. 



In another series of experiments with eight pigs, seven 

 months old, and " more finely framed " than the preced- 

 ing pigs, 1 Ib. of codfish was given to each pig, per day, 

 with, in one pen, barley-meal alone, and in the other, with 

 a mixture of 2 parts barley-meal, and 1 part bran. 



In pen 4, the pigs ate 7 Ibs. of codfish, and 49 Ibs. of 

 bran and barley meal each, per week, and gained 9.40 Ibs. 



In pen 5, the pigs ate 7 Ibs. of codfish, and 57 1 1 2 Ibs. 

 of barley-meal each, per week, and gained 11.75 Ibs. 



These facts will prove interesting and useful to farmers 

 living near the sea-shore, in localities where fish are used 

 for expressing oil, and where the refuse is sold for manure, 

 or for food for pigs. An analysis of this refuse, taken in 

 connection with the above experiments, should indicate 

 its value as food for pigs, and it is an easy matter to cal- 

 culate the value of the manure made by the pigs.
