TESTS WITH LAMB HEART. 
The results of the tests with lamb heart are presented in Table 17. 
None of the birds fed the ration which contained 15 per cent lamb 
heart developed polyneuritis during the test period of 63 days; one 
bird lost 7.4 per cent in weight, while the two others gained 3.7 and 
2.7 per cent, respectively. Three pigeons were fed a ration con- 
taining 25 per cent lamb heart; one developed polyneuritis on the 
chet toarth day, even though it had gained 8.5 per cent in weight; 
the two other birds were in fine condition at the close of the test on 
the sixty-third day. Figure 27 shows the changes in weight of 
pigeons that were fed lamb heart. |
