Abstract:

The aim of this study was to compare the frequency and duration of nest-building behaviours within the last 10 h before parturition and to compare the time and reason of piglet losses caused by the sow within the first 72 h after parturition in a group housing farrowing system (GA) and the farrowing pen FAT2. Furthermore disturbances of the nest building behaviour by other sows were investigated in the GA. A total of 17 sows (FAT2 = 10, GA = 7) and 25 crushed piglets were used for comparisons. The most frequent nest building behaviour was rooting in both farrowing systems. Sows in GA showed significantly more often pawing than sows in FAT2 sows in FAT2 tended to root more often; no further significant differences were found for the nestbuilding behaviours. Disturbances of the nest building behaviour in the GA didn`t occur. There were no significant differences regarding and cause of crushed piglets between the farrowing systems. A total of 11,9 % of live born piglets were crushed by the sow (n = 25). In the first 24 h after parturition most piglets died (48 % of crushed piglets). The fewest piglets died on day 3 after parturition (16 %). Rolling behaviour of sows caused the most crushed piglets (80 %) followed by lying down movements (12 %) and stepping of the sow on the piglets (8 %). Comparison of the two farrowing systems did not reveal major differences in either the nest-building behaviour or in crushing losses. Therefore, considering nest-building behaviour and crushing losses the group housing system may be regarded similar to the single pen FAT2.
