Preliminary Studies Show that 

 Choline Aids in Preventing Body 

 Weight Losses in Laying Hens. Al- 

 though it has been well established 

 that choline is essential for the 

 growth of chicks and poults, little 

 is known concerning its importance 

 for laying hens. 



A synthetic ration has been de- 

 veloped which is choline-free accord- 

 ing to our analysis. This was fed 

 to one group of hens; another group

received this basal ration with chol- 

 ine added, and the third group re- 

 ceived a control ration consisting of 

 a commercial all-mash laying ration. 



The experiment ran for 112 days. 

 During this period the hens on the 

 control ration maintained their body 

 weights. The hens receiving the 

 basal ration without choline lost con- 

 siderable weight and declined in egg 

 production. The basal ration with 

 choline added slowed the decline in 

 body weight and egg production. 



This study is being continued and 

 emphasis next year will be placed on 

 the possibilities of replacing the 

 amino acid methionine with the less 

 expensive choline.
