TESTS WITH LAMB LIVER AND HOG LIVER. 



In Table 15 are presented the results of the feeding tests with 

 lamb liver and hog liver. The ration containing 15 per cent of 

 lamb liver had a very low antineuritic value, the average survival 

 period of the pen of birds being only 21 days and the loss in weight 

 11.4 per cent. The ration which contained 25 per cent of lamb 

 liver had a considerably higher antineuritic value, the survival period 

 for the pen being 62 days out of a possible 70 days. One pigeon 

 developed polyneuritis on the thirty-eighth day, one died from an 

 injury on the sixty-eighth day, and the three other birds completed the 

 test. 



The results of the tests with hog liver were more favorable than 

 those with lamb liver. The pen of pigeons getting 15 per cent of 

 hog liver in their feed showed a survival period of 62 days out of 

 a possible 70. One bird developed polyneuritis on the thirty-seventh
