remedy two or three times a day. At this rate the animal will re- 

 ceive only a very minute quantity of the drugs in the remedy. In 

 verterinary practice the prescribed doses of these drugs are from 

 five to ten times greater than could be obtained by following the 

 manufacturers' directions. It is difficult to imagine that such a 

 method of treatment could be effective in curing any one of the dis- 

 eases mentioned, not to mention the wide range of diseases enumer- 

 ated by the manufacturers. 



Feeding Experiments Testing the Value of Condimental Feeds and 



Tonics. 



As these condimental feeds and tonics met with a large sale in 

 many parts of this country and abroad a number of experiment 

 stations have conducted experiments to determine the actual value 

 of these preparations for all kinds of animals and to prove or dis- 

 prove the extensive claims made by the manufacturers lor their 

 remedies. 



The following summary of experiments are abstracts from the 

 reports of the stations where these experiments have been conducted. 



Summary of Feeding Experiments with Condimental Feeds. 



Lindsey at the Massachusetts Experiment Station/ tested the value 

 of Pratt's Food with dairy cows in comparison with corn meal and 

 wheat middlings. He concludes that Pratt's Food did not substan- 

 tially increase the quantity of milk and milk ingredients over that 

 produced by a like amount of ordinary feeds; that Pratt's Food 

 failed to increase the richness of the milk ; that the cost of milk and 

 butter was increased fully 10 per cent when Pratt's Food was fed ; 

 that no effect favorable or otherwise upon the general health and 

 condition of the animals was noted from the addition of Pratt's Food 

 to the daily ration. 



Kennedy and Marshall at the Iowa Experiment Station,^ con- 

 ducted an extensive series of feeding experiments with steers, using 

 rations consisting of combinations of standard feeds alone and mixed 

 with condimental stock foods to determine the value, if any, of con- 

 dimental foods in fattening steers for market. In each case the prof- 

 its obtained per steer were considerably less when a condimental 

 food was included in a ration than when a straight ration was fed. 

 The condimental foods tested were Iowa, International and Standard. 

 Iowa Stock Food gave the best returns of any of the condimental 

 foods. International standing second and Standard third. 



The same investigators' conducted feeding experiments to deter- 

 mine the value of several feeds when fed in conjunction with corn
