DESCRIPTION OF FEED STUFFS 



do not keep as well as rutabagas and will only produce 

 about 3,500 pounds of dry matter to the acre. They ma- 

 ture quickly and are of value to sow late in the season as 

 a catch crop. 



Stock carrots will produce about 5,000 pounds of dry 

 matter to the acre and are well liked by poultry. They 

 are not as easy or as economical a crop to produce and 

 harvest as mangels or rutabagas and are not fed exten- 

 sively to poultry. 



Potatoes will not produce dry matter nearly as eco- 

 nomically as these root crops because of their extensive 

 use as a human food, and only small unmarketable po- 

 tatoes are used for feeding poultry. A yield of 200 bush- 

 els of potatoes to the acre will give 2,500 pounds of dry 

 matter. Potatoes should be boiled or steamed before 

 being fed to poultry and may be used to advantage by 

 mixing them in with the mash. Potato sprouts and un- 

 ripe potatoes contain a poisonous compound called 

 solanam and they should not be fed to fowls. The water 

 in which potatoes are cooked is usually bitter and it is 

 better not to use this liquor in mixing the poultry mash. 

 Sweet potatoes are grown extensively in the South and 

 when cooked are greatly relished by poultry. They are 

 not usually fed much foi this purpose because of their 

 high value as a human food. One hundred hens will eat 

 about 12 pounds of potatoes daily. Dried potato flakes 

 are used somewhat in feeding stock, especially in Ger- 

 many and probably could be used for poultry in this coun- 

 try if available at an economical price.
