32 EXPERIMENT STATION. [Jan. 



CONDIMENTAL AND MEDICINAL STOCK 

 AND POULTRY FOODS. 



BY J. B. LINDSEY. 



Several years ago the station made quite an exhaustive study 

 of the composition of this class of feeds, and published its 

 results in Bulletin No. 106, the edition of which has long since 

 been exhausted. It is intended in what follows to give a resume 

 of the most important points made in the bulletin, in order to 

 answer the frequent inquiries which come to the station con- 

 cerning them. 



It is not thought advisable to publish in this connection the 

 detailed composition of each brand as it was given in the bulle- 

 tin, as it may have been modified to some extent since the exam- 

 ination was made. It is believed, however, that the following- 

 statements will prove sufficient to enable every one to form a 

 correct opinion concerning their general character, commercial 

 value and utility. 



Basic ob Eood Ingredients. 



The chemist and microscopist have found these foods to con- 

 sist principally of ordinary grains and concentrates, such as 

 wheat by-products (bran and middlings) and corn meal. In 

 some cases a few hundred pounds to the ton of linseed, cotton- 

 seed and occasionally meat and bone meal have been added, 

 obviously to increase the amount of protein ; such mixtures con- 

 tained from 10 to 20 per cent, of that nutrient. Occasionally 

 the presence of considerable quantities of mustard hulls, cocoa 

 shells and weed seeds are noted, used evidently as a filler. 



The poultry foods more frequently reveal the presence of from 

 10 to 50 per cent, of ground oyster shells or noticeable quantities 

 of ground bone, which accounts for the exceptionally high ash 

 percentage.
