no matter how they are fed. It is necessary to have a 

 good animal, well fed, for good returns. Either condition 

 without the other will result in a financial loss. 



280. Condimental Foods. Numerous condimental stock 

 foods are advertised. These are guaranteed to make hens 

 lay, cows give milk, or pigs get fat. The basis of nearly 

 all of these is some common feed. Other ingredients are 

 salt, fenugreek, gentian, ginger, sulfates of iron, and soda, 

 pepper, sulfur, charcoal, etc. Substances that counteract 

 each other are sometimes included. 



Some of these substances have a tonic effect and may 

 at times be needed, but it is rarely desirable for animals 

 or men to take tonics all the time. If we desire to feed 

 any of these, they can be purchased at a drug store and 

 at a very -small fraction of the cost in patent foods. 



Numerous feeding experiments have failed to show 

 the value of these feeds. If one desires to use them, he 

 had best get a prescription from a veterinarian, or write 

 to the State Experiment Station, and save his money 

 for some useful purpose. .
