Enriching the sow environment and diet during gestation therefore improved sow welfare and reduced piglet mortality at and soon after birth.

Piglet stillbirth was associated with several hematological parameters of the sow, namely hemoglobin concentration, mean cell hemoglobin concentration...

The results of this study show opportunities to reduce harmful biting behaviours in pigs.

The possibility of planning the production level has a special importance for AI stations, and its inaccuracy should be minimized by eliminating the factors differentiating the quantity and quality of the ejaculate.

It is expected to improve the genetic progress of shoulder lesions and body condition score.

The possible mechanism of vitamin D action on boar performance was explored.

A genome-wide association study was performed to identify quantitative trait loci for SLP-related traits. A total of five genome-wide suggestive significant single nucleotide polymorphisms were identified.

This study was conducted to evaluate the underlying physiological changes during heat stress and the effect of betaine supplementation in lactating sows.

The results of this study provide clinical information on how to reduce seminal shedding of type 1 PRRSV in boars using type 1 PRRSV-modified live vaccine.

The present study was designed to evaluate the effect of porcine oocytes exposure to oviduct fluid before in vitro fertilization, during in vitro fertilization and during in vitro fertilization in combination with heparin.

The effects of infection by E. coli were dependent of both bacterial load and storage period, whereas the effects of C. perfringens were mainly dependent on the bacterial load.

Age- and seasonal-related variations affect the reproductive tract functions in the boar.

This study used flow cytometry to demonstrate stable incorporation of nanoliposomes prepared from a complex mixture of various phospholipids.

Retaining sows in the herd longer has economic benefits that could increase the financial returns of a breed-to-wean system.

In this study, CD163-positive fetuses were completely protected from PRRSV in dams possessing a complete knockout of the CD163 receptor.

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.

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

UCP1 KI pigs are a potentially valuable resource for agricultural production through their combination of cold adaptation with reduced fat deposition.

Sperm motility, morphology and three seminal plasma proteins were positively associated with heterospermic boar fertility.

The objective of the present study was to evaluate the effect of a subclinical inflammation on the pubertal development of boars and hence on fat androstenone.

Farms with appropriate management, feeding and housing conditions have reduced levels of mounting and aggressive behaviour.

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.

The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.
