The use of hyperprolific sow lines has increased litter size considerably in the last three
decades. Nowadays, in some countries litters can reach up to 18–20 piglets being a major …

Simple Summary Understanding the physiological mechanisms responsible for the
reproductive and productive development of modern sow genotypes will help to create or …

We investigated the effects of dietary supplementation with Bacillus subtilis PB6 (B. subtilis
PB6) during late gestation and lactation on sow reproductive performance, antioxidant …

Simple Summary Sows in most breeding herds worldwide have larger litters than several
years ago. One of the most important problems when using these genetics is the prolonged …

Highlights•Nesting behaviour and the frequency of postural transformation
investigated.•Values of both characteristics significantly increased before sows farrowing.• …

It was hypothesized that prolonged parturition and impaired placenta expulsion increase the
risk of postpartum metritis and delay uterine involution. At parturition, for 99 Yorkshire x …

Simple Summary A long birthing process is not only stressful for both the sow and her
piglets, it also decreases the chances of survival of piglets during birth or in the first days of …

Background Prolonged farrowing and more piglets born with low birth weight are
undesirable consequences of genetic selection for increased litter size. The objective of the …

The hypothesis was that a prolonged parturition impairs placenta expulsion and can lead to
retained placentas in sows. Furthermore, we hypothesized that application of oxytocin …

Contents In this review, we address significant characteristics of parturition in the pig and
their connection to post‐partum reproductive health and fertility. We discuss the normal …
