egg production for four months previous to the hatch, they having been 

 confined to laying pens instead of having outdoor range. 



SUMMARY 



From the experimental evidence which is at hand it is quite apparent 

 that the feeding of Fleischmann's Pure Dry Feed Yeast in the fermented 

 moist mash to breeding hens very materially increases the fertility of the 

 hatching eggs produced. 



On the same basis it is very evident that the feeding of Fleischmann's 

 Pure Dry Feed Yeast in a fermented moist mash very materially increases 

 the hatchability of eggs so produced. 



It is further evident that chicks produced from yeast-fed breeders have 

 more vitality and are more disease-resistant as measured by the very 

 material increase in percent of livable chicks at the end of three weeks of 

 brooding. 



The advantage of feeding yeast in the form of a fermented moist mash 

 is very evident, due primarily to the great increase which takes place in 

 the actual volume of yeast during the process of fermentation.
