Use of the controlled release devices significantly reduced circadian variation in the chromium sesquioxide concentration in faeces, compared with twice daily dosing with gelatin capsules. Consequently, variability was lower and biases in estimates of faecal output were relatively small. Once daily grab sampling from sheep with controlled release devices produced more reliable estimates of faecal output than twice daily sampling from sheep with gelatin capsules.
