SUMMARY 
Lactose, up to 8 gm. per hen per day, was utilized fairly completely, 
thus making it evident that the lactose present in the quantity of whole 
milk, skim milk, whey, or buttermilk normally consumed (ioo to 200 cc.) 
by chickens would be completely absorbed. 
When lactose appears in the excreta, it is usually accompanied by 
glucose. 
Lactose when fed mixed with a moist mash acts as an irritant to the 
gastrointestinal mucosa. Chickens will not voluntarily consume more 
than about 8 gm. of lactose daily when fed in the form of pure lactose 
mixed with the feed.
