COMMEECIAL EGGS IIST THE CENTRAL WEST.

other characteristics are normal, but that eggs showing more advanced 

 decomposition should be avoided. This phase of the egg problem will 

 be specially investigated during the season of 1913. 



BLOODY WHITES. 



Many of the first eggs laid by pullets contain blood which may 

 be diffused through the white or may be in the form of clots on the 

 yolk or in the albumen (see PL IV). It is probable that in the 

 passage of the white and yolk through the oviduct some of the small 

 blood vessels are ruptured, thereby allowing blood to gain access to 

 the white or yolk before they are incased in a shell. 



The examination of six individual eggs of this type disclosed the 

 presence of less than 5,000 organisms per gram. No B. coll were 

 found, except iii one sample, which had only 10. The eggs were 

 taken from the cups of the breakers ; consequently the few organisms 

 found are very likely referable to outside sources and not to the eggs. 

 On account of the presence of blood, these eggs are not used for food 

 purposes. 



EGGS WITH BLOOD RINGS. 



Eggs showing signs of incubation were discussed quite fully on 

 page 13; consequently only the information gained when these eggs 

 were broken commercially will be given here. 



During May, 1912, four samples, consisting of from 3 to 12 large 

 blood rings, were taken. Since the weather had not been warm 

 enough to cause spontaneous development of embryos of fertile eggs, 

 these blood rings were probably the result of the undesirable practice 

 of selling incubated eggs which would not hatch. The yolks were 

 broken and partially mixed with albumen; the germinal disk was 

 deteriorated. The odor of each was good.
