This study showed the potential to select on longer interval from last insemination to culling in days and thereby select against sows to be culled within the reproduction, locomotion, accident, general disorder and peri-partum cull class and to be culled at the end of a parity.

Radiant heating behind the sows reduced hypothermia in new-born piglets and indicate that providing heat during the first half hour after birth is important.

More than 85% of primiparous sows can be successfully post-cervical inseminated with doses containing 1.5 × 109 sperm cells in the absence of the boar during insemination without impairing the reproductive performance.

Loose-housing of lactating gilts after a reduced postnatal crating period of 7 days affected neither the activity level of the gilts and lesions on the integument nor pre-weaning mortality. Therefore, it is recommended to allow sows to move around to some extent during the later lactation period.

Sow dietary supplementation with aniseed extract during late gestation and lactation improves milk yield and litter performance.

Diet deprivation and subsequent over-allowance during gestation does not impair postnatal piglet growth.

In conclusion, a greater PRL/P4 ratio 24 h prepartum, characterized by lower P4 concentrations and a trend for greater PRL concentrations peripartum, led to increased colostrum yield in primiparous sows.

On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.

High PBA in parity 1 can be used to predict that a sow will have high reproductive performance and lifetime performance.

Magnesium supplementation can increase reproductive performance in adult sows.

These baseline results suggest that oral-fluid samples can be collected from individually housed sows, but that further studies on the optimization of oral-fluid collection in the sow unit (gestation and farrowing) would be of value.

Insulin, ghrelin and leptin could be used as biomarkers to detect situations resulting in a poor energy balance.

The dietary fish oil inclusion may prevent  lameness appearance in  sows.

Insulin, acylated ghrelin and cortisol could be used as biomarkers to detect situations resulting in a poor energy balance in order to improve handling programs.

Keeping group-housed gestating sows on partly straw bedded floor with permanent access to the concrete feeding stalls compared to fully straw bedded floor did not significantly influence animal performance and NH3-emissions, and decreased CO2eq-emissions.

Tryptophan requirement of pregnant sows increases from 1.7 g/d in early to 2.6 g/d in late pregnancy.
