Stillbirths in relation to sow hematological parameters at farrowing: A cohort study
Piglet stillbirth was associated with several hematological parameters of the sow, namely hemoglobin concentration, mean cell hemoglobin concentration...

Indirect genetic effects for growth rate in domestic pigs alter aggressive and manipulative biting behaviour
The results of this study show opportunities to reduce harmful biting behaviours in pigs.
The effect of age, interval collection and season on selected semen parameters and prediction of AI boars productivity
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.
The genetic correlation between scapula shape and shoulder lesions in sows
It is expected to improve the genetic progress of shoulder lesions and body condition score.
Effects of the different levels of dietary vitamin D on boar performance and semen quality
The possible mechanism of vitamin D action on boar performance was explored.
Genome-wide association study for sow lifetime productivity related traits in a Landrace purebred population
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.

Effects of betaine and heat stress on lactation and postweaning reproductive performance of sows
This study was conducted to evaluate the underlying physiological changes during heat stress and the effect of betaine supplementation in lactating sows.
Two commercial Type 1 PRRSV-modified live vaccines reduce seminal shedding of Type 1 PRRSV in infected boars
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.
Combination of oviduct fluid and heparin to improve monospermic zygotes production during porcine in vitro fertilization
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.
A comparative study of the effects of Escherichia coli and Clostridium perfringens upon boar semen preserved in liquid storage
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-dependent variations in the biochemical composition of boar semen
Age- and seasonal-related variations affect the reproductive tract functions in the boar.
Fusion of boar sperm with nanoliposomes prepared from synthetic phospholipids
This study used flow cytometry to demonstrate stable incorporation of nanoliposomes prepared from a complex mixture of various phospholipids.
An economic analysis of sow retention in a United States breed-to-wean system
Retaining sows in the herd longer has economic benefits that could increase the financial returns of a breed-to-wean system.
Protect fetuses from infection with PRRSV
In this study, CD163-positive fetuses were completely protected from PRRSV in dams possessing a complete knockout of the CD163 receptor.
Factors of importance when selecting sows as embryo donors
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.
Reproductive performance following non-surgical deep uterine porcine embryo transfer
The aim of this study was to evaluate the effects of the weaned recipients' parity on fertility and prolificacy following NsDU-ET.
CRISPR to make a reduced-fat pig
UCP1 KI pigs are a potentially valuable resource for agricultural production through their combination of cold adaptation with reduced fat deposition.
Use of heterospermic inseminations in boar fertility
Sperm motility, morphology and three seminal plasma proteins were positively associated with heterospermic boar fertility.
Influence of the inflammatory status of entire male pigs on their pubertal development and fat androstenone
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.
Evaluation of producing and marketing entire male pigs
Farms with appropriate management, feeding and housing conditions have reduced levels of mounting and aggressive behaviour.
Outcomes of gestation length in relation to farrowing performance
Premature births increase the number of intra-partum deaths and result in lower birthweights, the presence of apnoea, and severe metabolic alterations in piglets.
Factors for improving reproductive performance of sows and herd productivity in commercial breeding herds
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 dependence of the growth rate and meat content of young boars on semen parameters and conception rate
The objective of the research was to conduct semen parameter and conception rate analyses on the basis of growth rate and meat content.
Characterizing body temperature and activity changes at the onset of estrus in replacement gilts
The study objective was to characterize body temperature and activity changes in replacement gilts at the onset of estrus in order to provide initial data to develop a remote estrus detection system for commercial swine operations.
