These results suggest that mixing sows in the 1st or 2nd week of gestation can result in reduced conception and farrowing rates when compared to housing sows in stalls.
The dilemma of fostering on the first day of life
The ingestion of Ig in sufficient quantity is the first priority. So much so that it even comes before the factor that seems most important: the feed supply.
Testing females to improve accuracy
With high-priced feed accounting for the major cost of production, it is important to test the females in all lines, as well as the males, since they contribute 50 per cent of the genetics to the next generation.
Monitoring of Farrowing (III): Factors that increase stillbirths
Long farrowings increase mortality, and deaths occur above all in the last 1/3 of the delivery.
CLA during last week of gestation and lactation alters colostrum and milk fat composition and performance of reproductive sows
CLA administration to sows reduces backfat thickness loss during the lactation period and lets to higher piglet weight at weaning.

UTIs are among the most frequent bacterial infections in the herd but they are rarely diagnosed or taken into consideration by veterinarians.
Effect of site of sperm deposition on fertility when sows are inseminated with aged semen
In the present study, intrauterine deposition of sperm did allow maintenance of farrowing rate, but did not ameliorate the adverse effect of inseminating aged sperm on litter size.
Denmark: status on 2013 legislation
Research undertaken in 2010 indicated that 70% of Danish producers now comply with EU legislation effective from January 2013, which will ban the use of traditional stalls for pregnant sows.
