POULTRY FEEDS AND FEEDING 



lowers the digestibility of feeds except of potatoes and 

 other starchy tubers, but may improve their palatability. 

 These are the only feeds used by poultry which it pays to 

 cook. The use of salt and the addition of lactic acid 

 (the chief acid of milk) does not directly improve di- 

 gestibility but has a beneficial effect on the fowls' appetite 

 and may stimulate greater consumption of feed.
