Mortality 



The mortality attendant on the change of ration was not large and 

 came mostly during the first week of fattening. After that the mor- 

 tality was due mostly to accident.

Pig. 177. — The mortality was low in all flocks during the six weeks of fattening, but 

 highest in the dry-mash flock. {Based on Table 12) 



The dry-mash flock (58) showed highest mortality, which was due 

 largely to natural causes and not to accident. (Fig. 177.) In appear- 

 ance this flock was the poorest in the experiment. One chick which 

 had previously been removed from 59 (powdered milk mash) because 

 of accident, and had been counted in the mortality, was returned to 

 the flock at the beginning of the fattening period. The total mortality 

 during the six weeks of fattening was 24 chicks, or 3.5 per cent.
