Samples of the salmon egg protein meal were sent to various re- 

 search laboratories for evaluation in the production of microbiologi- 

 cal antibiotic substances 'and as a substitute for other proteins in 

 the growth of poultry and small animals. Results of these investiga- 

 tions will be available for publication at a later date. 



A study of the salmon egg protein meal to determine any residual 

 toxicity toward rats was carried out because of a report the authors 

 had received in a personal coramxinication to the effect that rats did 

 not thrive on salmon egg protein. Accordingly a feeding study 1/ vras 

 undertaken to evaluate the salmon egg protein in comparison with 

 casein. 



Basic diet for the groups fed was as follows: 



2/ For the control group, 25 percent technical casein and 

 5 percent dextrin were substituted for the 30 percent 

 salmon egg protein. 



White rats were allotted to the two groups at random and kept 

 in individual cages. Food and ivater were allowed ad libitum . Data 

 including rat weight and food consumption were recorded weekly. Gain 

 in body weight to food consumption was calculated and is presented 

 in Table 6,
