The post-cervical insemination does not impair the reproductive performance of primiparous sows

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.

Confinement of sows for different periods during lactation: effects on behaviour and lesions of sows and performance of piglets

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.

Moderate changes in the nutrition of gestating sows have no harmful effects on the development of their offspring

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

Relative prolactin-to-progesterone concentrations around farrowing influence colostrum yield in primiparous sows

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.

The use of oxytocin in liquid semen doses to reduce seasonal fluctuations in the reproductive performance of 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.

Reproductive performance of sows can be predicted by high numbers of pigs born alive in parity one

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

Collection of oral fluid from individually housed 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.
