28 AGRICULTURAL EXPERIMENT STATION. [Jan. 



The o-eneral condition of the animals at the ciose of the 

 observation was a satisfactory one. 



Conclusions . 



A careful consideration of the previously recorded results 

 leads us to the following conclusions : — 



1 . The substitution of a ration composed of three pounds 

 each of corn meal, maize feed and wheat bran, by one con- 

 sisting of three pounds each maize feed, wheat bran and 

 cotton-seed meal, has in our case not 7naierially changed the 

 market cost of the grain feed ration, but reduced two cents its 

 net cost, in consequence of the more valuable manurial refuse 

 of the latter. 



2. The quantity and quality of milk has not been affected 

 in any noticeable degree by the change in the grain feed 

 ration in case of healthy animals. 



3. The differences in the cost, both market and net, of the 

 diferent fodder rations, are in a controlling degi'ee due to 

 t/ie cost of the different coarse fodder articles used, — a fact 

 which has been repeatedly j>ointed out in previous coinmuni- 

 cations.
