03-Dec-2010 (15 years 6 months 3 days ago)The objective of this study was to determine the incidence of premature birth (<114 days of gestation) in the reproductive performance of sows. For this purpose a total of 60.990 reproductive data registers of 17.401 sows housed on 35 farms were analyzed.
The sows with a gestation <112 days had the highest number of stillborn piglets and less live births in comparison to the sows with gestations of 114-117 days. The sows with a gestation ≥ 118d were more prone to have less stillborn piglets and fewer live births when compared with sows that completed gestation. The sows with a gestation less than 114 days were more prone to have a second gestations lasting less than 114 days: the same occurred with sows with a gestation lasting longer than 114 days. This information can be helpful for farmers faced with identifying sows in possibly risky situations.
