This study reports a method of measuring sheep activity in confinement based on recording movement of sheep during weighing. The aim was to show that an algorithm to analyse continuous weight records could be used to measure activity quickly and efficiently using commercial weighing equipment and that this measurement is related to animal productivity, specifically liveweight. A prototype method required magnetic switches on the weighing crate to record gate positioning and enclosure of the animal, with data analysis subsequent to the completion of weighing. The method reported here does not require additional equipment, instead using a computer program to analyse weights in real-time to record the degree of sheep movement. The result is summarised as the coefficient of variation of the weight over a period of 8–20s and reported as an activity score. The real-time method had a higher repeatability (P
