Extract

Where indirect calorimetry and slaughter techniques have been compared previously (eg: Geay, 1984; Beever et al, 1988) estimates of energy retention have tended to be greater from calorimetry than from slaughter studies. However, in most instances each technique was applied to a different group of animal and over only a limited range in energy retention. The aim of this work was to examine the difference between estimates of energy retention obtained using a direct technique (comparative slaughter) (ERs) and an indirect technique (open circuit respiration calorimetry) (ERc) applied to the same group of animals and over a relatively wide range of energy retentions.
