TABLE NO. 2 



GENERAL RESULTS OF FALL HATCH 



In order to analyze the data shown on the above table intelligently and 

 arrive at a comparative summary of the efficiency of the hatch from the 

 yeast and non-yeast fed pens the following table No. 3 shows first, the 

 detailed results secured from the hatch of 750 eggs produced by the yeast 

 fed breeders and also the general results secured from the hatch of 600 

 eggs in four trays from the non-yeast fed breeders.

It will be observed that where yeast was fed only 147 eggs were candled 

 out as infertile from the 750 eggs set. Where no yeast was fed 193 eggs 

 were candled out of 600 eggs set. When observing the very poor fertility 

 resulting from the non-yeast fed pens it must be remembered that these 

 birds had been laying heavily since late July, occasionally reaching as 

 high as 70% production.
