MAlSrUAL OF CATTLE-FEEDIlSra 



is sufficient for a Iiorse weigliing about 1,200 pounds and 

 performing only light work. All the experiments in which 

 the total quantity of digested matter falls below this amount 

 show a loss of weight, while those in wdiich it is exceeded 

 show a gain. It would seem, from the lif th experiment, 

 that the nutritive ratio may safely be made considerably 

 narrower than that given above ; but such a change WT)uld 

 only increase the cost of the feeding without producing an 

 essentially better result. 



The few experiments in which the amount of work was 

 increased to an ordinary day's work, or somewhat beyond, 

 only show the insufficiency of the above mentioned ration, 

 but give us no information as to the amount by which it 

 should be increased. It is noticeable that in these experi- 

 ments the loss of weight was less on a wide nutritive ratio ; 

 at the same time, however, the total amount of digested 

 matters was somewhat greater, though that of the protein 

 was much less. 



Feeding Standards. — The following table contains the 

 above feeding standard, calculated per 1,000 pomids live- 

 weight, and also the standards reconnnended by Wolft" for 

 ordinary and for heavy work :
