The future design of AI strategies and catheters should take into consideration the morphological variations of the cervix lumen, which will depend on age and parity of the females.

Sow dietary CLA supplementation may be transferred in colostrum enhancing piglets’ immunity leading to lower mortality rates.

Dietary levels of 1.8 and 2.2 kg/d in late gestation do not differ on reproductive and piglet performance.

The improvement in porcine embryo preservation and non-surgical embryo transfer (ET) procedures achieved in recent years represents essential progress for the practical use of ET in the pig industry.

Three experiments were conducted to investigate the implications of replacing farrowing crates with an alternative housing system from 3 days postpartum until weaning.

The aim of this study was to evaluate the effects of the weaned recipients' parity on fertility and prolificacy following NsDU-ET.

The SID Lys:ME ratio during lactation depends on a milk yield and the body weight of the sow.

Effect of feeding time and frequency during gestation does not affect farrowing performance.

High feeding level during the wean-to-oestrus may increase farrowing rate but also may increase stillborn rate and reduce piglet birth weight.

Premature births increase the number of intra-partum deaths and result in lower birthweights, the presence of apnoea, and severe metabolic alterations in piglets.

We review critical factors associated with reproductive performance of female breeding pigs, their lifetime performance and herd productivity in commercial herds. The factors include both sow-level and herd-level factors.

Although the better sow and litter performance for group housed sows with electronic feeding system some improvements are still required in terms of body scratch and locomotion disorders.

Increasing feeding level during gestation may improve piglet body weight at birth but have a negative impact on feed intake and backfat loss during lactation.

The use of palygorskite in sow diets reduces oxidative stress in gestating sows.

A high avulation rate results in an moderate increase in the number of vital embryos at day 35 of pregnancy, but compromises development in the surviving embryonic/placental units, suggesting that the future growth and survival of the embryos might be further compromised.

The current study demonstrated that the farrowing system design can influence sow behaviour, with pens allowing for more interactions between sows and their piglets.
