Constitutional Vigor in Poultry

PART III 



THE PROGENY FROM THE ORIGINAL FLOCKS 



The third part of this bulletin records the observations made on the 

 progeny from the pullets in the original pens. All the pullets matured 

 from the weak flocks were saved. If the number in the strong flocks 

 exceeded that in the weak, they were culled to an equal number. No 

 further selection was made. Two weak males (cockerels) were put in 

 pen 13 (weak). In all the other pens strong males were used. In 

 general care and management the treatment of these flocks was similar 

 to that of their parents. 



FOOD consumption 



The second generation consumed more food per fowl than did the first 

 generation. In every instance the food consumption was greater in the 

 strong pen, and the average consumption of ground food was of about 

 the same proportion as it was with the first generation. In each instance, 

 except the fall-selected White Leghorns, the strong flocks consumed 

 the greater amount of ground food. Since the mash contained the meat 

 scrap, this weak flock (13) consequently consumed more of the meat 

 than did the corresponding strong flock. This fact may partially explain
