Abstract

The extent to which the size of the gestation stall, relative to the size of the sow, affects the normal basic pastural behaviaural needs of sows like standing, sitting and lying was assessed using 25 sows randomly selected from four farms. The pastural behaviaur of the animals was recorded using a time-lapse video recorder. The relationships of duration of postures, time taken for various pastural changes and frequency of pastural changes with stall measurements in relation to sow measurements were analysed. Negative correlations (P < 0.01) were found between stall length relative to sow length and the duration of time for which the sows were standing. The relationships between the duration af pastures and stall width relative to animal breadth were not different (P > 0.05). The time taken to change from a standing to lying posture was negatively correlated (P < 0.05) with stall length relative to animal length. Similar correlations (P < 0.05) were noted between stall width relative animal breadth and the duration of pastural change from standing to sitting and from sitting to standing. Stall width relative to animal breadth was negatively related to the frequency of pastural change from standing to sitting (P < 0.05). The results suggested that the freedom of movement of pregnant sows in stalls could be improved by a little increase in the space allowance within the stall.
