those receiving low protein rations. In Test II at the end of the first 

 12- week period the group receiving a 19 per cent protein ration from 

 dried skimmilk as animal protein source was lowest in weight, averaging 

 l^er pullet chick 1.913 pounds (Table III) . The group receiving the 19 

 per cent mixed protein was highest in average weight with 2.846 pounds 

 per chick. 



The use of a 19 per cent protein ration using dried skimmilk did not 

 cause more rapid weight gains. This tends to support our previous state- 

 ment that there is a limit beyond which we should not go in the feeding 

 of this product to insure rapid weight gains. The 17 per cent protein 

 group carried 17.3 per cent of dried skimmilk and the 19 per cent group 

 carried 25.2 per cent. Kempster and Funk^^ have concluded that growi:h 

 in White Rock chicks was in proportion to the amount of dried skimmilk 

 used in the ration until the amount was over 30 per cent. 



In summary, according to type of animal protein concentrate received, 

 the fish meal groups averaged highest with 2.756 pounds per chick, 

 followed in order by mixture, meat scrap and dried skimmilk, showing 

 2.654 pounds, 2.321 pounds, and 2.101 pounds, respectively. One point 

 of interest in the weight records is evidenced by the lack of variance in 

 average weight per chick for the fish meal groups. Only slight differ- 

 ences in weight were occasioned by the increase in percentage of fish meal 

 used in the ration. 



The groups receiving dried skimmilk were definitely inferior in weight.
