FEEDING TESTS WITH SHEEP MUSCLE. 



The results of the feeding test with sheep muscle are shown in 

 Table 5. Each sample of muscle was derived from a single hind 

 saddle of lamb, i. e., the two hind quarters. Sample 680 used in the 

 rations fed to pens 15 and 16 represents a fairly fat, medium- weight 

 carcass; sample 716 was taken from a light carcass of the same qual- 

 ity; while sample 719 represents an extra-fat, heavy-weight carcass 

 of superior quality.

The result of the test with pen 15 indicates that the ration contain- 

 ing 15 per cent of lamb muscle, No. 680, had a very low antineuritic 

 value, about the same as that of the autoclaved polished rice fed to 

 pens 2 and 3. The antineuritic value of the ration w r hich contained 25 

 per cent of the same lot of lamb muscle was somewhat higher as 

 measured by the survival periods of the two pens of birds, but the 

 loss in weight was about the same.
