Overall, I consider the concept of bio-organic spaceships (especially 
if they are supposed to have evolved naturally) to be so far out that 
discussing them in the same paragraph as the laws of thermodynamics
really make sense.

Still, FWIW: 
1) IIRC the efficiency in converting food into body mass of terrestrial 
life is markedly different for warm-blooded and cold-blooded animals. 
Which class do the Savasku belong to ?
2) The laws of thermodynamics don't deal with the conversion of 
materials, but with the conversion of energy. The main source of waste
biological is the need for energy, which is obtained by chemically
high-energy-molecules (sugars, fats etc.) into low-energy 'waste' 
molecules (carbon dioxide, water) which are of no use and excreted. If
Savasku have available 'unlimited' energy (from a biological 
fusion-reactor, say), they may be able to make use of all the target
ships' mass.
