In Danish organic pig production, one-third af total bom piglets die befare weaning, and stillbirth has previously crudely been estimated to account for 2 7% af the total preweaning mortality. The objective af this study was to evaluate season, litter size, parity and body condition af the sow as risk factors for stillbirth in nine commercial Danish organic pig herds. The study was conducted over a 1-year period, and the data included registrations an 5170 farrowings with 82 906 total bom piglets. The average number af total bom piglets per titter was 16. 0, and the number af stil/bom piglets per titter was 1.1. A significant effect af season was seen with an odds ratio for stillbirth af 1. 15 during summer (May to August) compared with the remaining part... |

Piglet mortality is a major problem in organic pig production affecting both farm economy and animal welfare. Knowledge is scarce on the risk factors of piglet mortality in Danish commercial organic pig production. The objectives of this study were to evaluate season, litter size, parity, sow body condition and stillborn littermates as risk factors for early piglet mortality and crushing of liveborn piglets from parturition until castration at day 3 to 5 postpartum (pp). The study was conducted over a 1-year period in nine commercial Danish organic pig herds practicing outdoor farrowing all year round. Data included recordings on 3393 farrowings with 50 284 liveborn piglets of which 14.8% died before castration. A subset of the dead piglets were collected... |
