| Prolonged farrowing duration has previously been related to hypoxia, stillbirth and poor sow health post partum (pp). A difficult farrowing may affect sow behavior through exhaustion, sickness or pain and thus constitute a risk for sub-optimal maternal behavior. The aim of the present work was to study if the duration of farrowing in an organic sow herd affected sow postural changes, carefulness of lying down and nursing behavior relevant for early piglet mortality. Thirty-eight sows and their piglets housed in individual paddocks with an A-frame hut were video recorded from the day of farrowing and the following 72 h. The average farrowing duration till the last live born piglet was 7.5 ± 7 h (2.1–28.9 h). The only effect found of farrowing duration was a... |

| The aims of the current study were to identify the causes of preweaning piglet mortality and investigate the effect of season and parity on the proportions of mortality causes. The study was conducted in nine herds over a one-year period, and dead piglets were collected for necropsy once during each of the four seasons. In total, 2672 piglets were necropsied of which 60% were live-born but died post-partum (pp), 32% were stillborn and 8% were euthanised. Intra-partum deaths accounted for 88% of stillborn piglets. Eighty-one percent of necropsied live-born piglets died within four days pp. Half of these had a body weight of <1 kg at the time of death. Crushed and starved piglets accounted for 83% and 9% of mortalities until day four pp, respectively.... |
