“…Furthermore, duration of farrowing (3.46±0.2h) in sows that received IVDs for 72h was similar to those induced with PGF2α in experiment 2 (3.6±0.6h) and to previous reports (LUCIA JR et al, 2002;OLIVIERO et al, 2010). The average rate of dead piglets was also within the expected range, based on previous studies ( VAN DIJK et al, 2005). Another study shown that prolonging the gestation to 116 days using i.m.…”

“…Furthermore, gilts that have low immunity to the diseases are at high risk of infection [3] and increased PPBD. High PPBD in high parity sows appeared to be due to the large numbers of total pigs born [4] and a poor uterine muscle tone of high parity sows [17], which are associated with prolonged farrowing duration, high risk of hypoxia for piglets [6,21] and an increased number of piglets of uneven sizes [22] including low weight of piglets. As the birth weight of a piglet decreases, the probability of the piglet being dead at farrowing increases [3].…”

ABSTRACT. The objectives of the present study were to measure a percentage of pigs born dead in the number of total pigs born (PPBD), and to investigate an association between PPBD and total pigs born by parity groups and three herd groups formed on the basis of the pigs weaned per mated female per 6 years (PWMFY). The studied data included 236,805 parity records of 51,443 sows in 110 herds. The three herd groups, high-, intermediate-and low-performing herds, were formed on the basis of the upper and lower 25th percentiles of PWMFY. Linear mixed-effects models were performed to analyze the data. Mean ( SEM) PPBD was 9.6 ( 0.03) %. Sows in high-performing herds had lower PPBD for all parity groups than those in low-performing herds (P<0.05). Parity 2 sows had the lowest PPBD between parity groups (P<0.05). The PPBD increased from 7.0 to 13.2% as the parity number increased from 2 to  6. Parity 1 sows had higher PPBD than parity 2 and 3 sows (P<0.05). As the total pigs born increased from 10 to 16 pigs, PPBD increased in all the parity groups (P<0.05). In parity 3 or higher, PPBD in low-performing herds increased more steeply than that in high-performing herds as total pigs born increased form 6 to 10 pigs. We suggest that farrowing management including assisted farrowing improve PPBD for sows in parity 3 or higher.

“…Sows experiencing early parturition (<114d) had an average 0.4-1.7 more piglets born dead in comparison with sows farrowing between 114 and 117 days of gestation (Vanderhaeghe et al, 2010c) and the reason assigned to it could be immaturity of the piglets (Zaleski and Hacker, 1993). Additionally, other studies suggested that the genital tract of sows experiencing an early parturition might not be well prepared for the parturition process to a significant increase in farrowing duration (van Rens and van der Lende, 2004;van Dijk et al, 2005).…”

Mummification is often noticed in pigs compared to other species due to large litter size. The agents responsible for the reproductive failure in sows may lead to a wide range of sequelae, including abortions, stillbirth, mummification, embryonic death. High prolificacy is associated with increased incidence of stillbirths and mummified fetuses. Plethoras of other foetal and maternal factors have been associated with incidence of still birth and mummification. Identification of those risk factors have been associated with stillbirth and mummified fetuses can helps in optimal herd reproductive efficiency.
