82 Feeds and Feeding. 



109. What the tables show. The first table shows that in every 

 instance the protein-rich ration produced heavier gains than the 

 others. In the several columns are given the weights of various 

 parts and organs of the body. Since pigs fed on the several 

 rations reached different weights at the time of slaughter, the 

 weights are reduced to a common standard for comparison. This 

 is done in the second table, where the weights of the different 

 parts are stated for each 100 pounds of dressed carcass. 



It is seen in the second table that the pigs fed the protein-rich 

 rations usually show a larger shrinkage than those getting corn 

 meal. This is accounted for in part by the larger amount of 

 blood, heavier livers and other organs of the protein-fed pigs. 



In nearly every instance the pigs receiving the protein-rich 

 rations yielded more blood than those fed corn. In the Kansas 

 trial the pigs getting shorts and bran had 51.2 ounces of blood to 

 100 pounds of carcass, while the corn-fed pigs had only 36.8 

 ounces. In Fortier's trials in France, the blood of the corn-meal- 

 fed pigs was less than half that of the pigs receiving the protein- 

 rich ration, the ratio standing 55.1 to 26.1. The only exception 

 was in the Wisconsin trial, where the pigs were made very fat 

 by feeding milk. 



In every instance the pigs fed the protein-rich rations had 

 heavier livers than the others, the difference often being very 

 marked. For example, in the Missouri trial the pigs fed mid- 

 dlings had livers weighing 48.4 ounces to 100 pounds of carcass, 

 while those of the lot fed corn weighed only 31.9. 



Generally, the kidneys of the protein-fed pigs are heaviest, 

 though in Fortier's trials the reverse occurs. 



The tenderloin muscles lying along the back of the pig are 

 easily dissected from the remainder of the carcass, and in one 

 trial in Wisconsin and in the Kansas trial these muscles were 

 separated and weighed. In both cases the muscles of the pigs 

 getting the protein-rich rations were heavier in proportion to the 

 weight of the body than those of the pigs fed corn. This is proof 

 of more lean meat in the carcasses of pigs fed the most protein. 



The pigs getting corn meal gave more leaf lard than the others, 

 excepting in the French trial, where the results were practically 

 equal.
