The groups were fed various protein carrying rations as outlined 

 below : 



Groups 1, 2, and 3: basal ration plus meat scraps to make 15, 17, 

 and 19 per cent protein content, respectively. Groups 4, 5, and 6 : 

 basal ration plus white fish meal, vacuum processed, to make 15, 

 17, and 19 per cent protein content, respectively. Groups 7, 8, and 9: 

 basal ration plus dried skimmilk to make 15, 17, and 19 per cent pro- 

 tein content, respectively. Groups 10, 11, and 12: basal ration plus a 

 combination of the three animal protein products in equal protein- 

 carrying amounts to make 15, 17, and 19 per cent protein content, 

 respectively. 



The basal ration was composed of 200 pounds yellow corn meal, 

 100 pounds wheat bran, 100 pounds white flour middlings, 100 pounds 

 ground heavy oats, 25 pounds alfalfa leaf meal, 15 pounds oyster 

 shell flour, 5 pounds salt and 3 pounds biologically tested sardine oil. 

 All groups were fed this ration plus the specified animal proteins in 

 an all-mash form throughout the experiments. 



All groups were weighed weekly throughout the first twenty-three 

 week period using a random selection of 10-25 birds as a unit and 

 calculating a simple average weight figure to apply to the group. 

 Following the twenty-third week of age these weights were calcu- 

 lated every other week. Feed consumption records were determined 

 weekly by groups throughout the experimental period. 



PROTEIN CONCENTRATES USED 



The concentrates used consisted of meat scraps, vacuum-processed 

 white fish meal, and dried skimmilk. The reader is referred to the 

 previously mentioned publication for more complete details con- 

 cerning their manufacture. Analyses of protein and mineral con- 

 tent of these concentrates and mixed rations are given in Table 1.
