The following table shows the basal katabolisni calculated by the 

 formula for animals in different condition but each having a live weight 

 of 454 kg. (10001b.): 



As between the lean (10 per cent.) and fat (40 per cent.) condition the 

 difference amounts to 1. 584 Cal. It appears, therefore, that the main- 

 tenance requirements of two animals of the same live weight may differ 

 by more than 30 per cent. The method of computing maintenance 

 rations in proportion to the two-thirds power of the live weight without 

 regard to condition has always been open to suspicion. In view of these 

 figures it appears to be quite inadmissible.
