Physiology and nutrition of late gestating and transition sows
The physiological processes and how they change dynamically as the sow approaches farrowing greatly affect sow productivity.
Abstracts - Genetics and reproduction
Characteristics of thermal images of the mammary gland and of performance in sows differing in health status and parity
Thermography coupled with Artificial Intelligence systems can help identify and orient the diagnosis of symptomatic animals to prompt adequate reaction at the earliest time.
New vaginal drug delivery system to control time of farrowing and allow supervision of piglet delivery
Findings confirm the efficacy of the novel vaginal drug delivery system for induction of farrowing in sows.
Does nursing behaviour of sows in loose-housing differ from that of sows in farrowing crates?
Shorter nursing duration and more nursing terminations by the sow were observed in loose housing than in farrowing crates.
Comparing gut microbiota and metabolic status of sows with different litter sizes during gestation
Microbial abundances and community structures differed significantly between sows with different litter sizes and gestation stages.
Polyamines protect boar sperm from oxidative stress in vitro
Spermine and spermidine alleviate oxidative stress via the antioxidant capacity, thereby improving the efficacy of boar semen preservation.

Intrauterine immunizations trigger antigen-specific mucosal and systemic immunity in pigs and passive protection in suckling piglets
The study assessed whether vaccines administered to the uterus at breeding can lead to sufficient colostral antibodies to protect suckling piglets against PEDV.
Impact of birth weight and daily weight gain during suckling on the weight gain of weaning piglets
Piglets with 1.25 to 2.30kg BW and low weight gain during suckling presented a partial compensatory growth during the nursery phase.
Effect of the boar on swine inflammation and necrosis syndrome in offspring
The effects of different boars from the Duroc and Pietrain breeds on the prevalence of swine inflammation and necrosis syndrome in their offspring.
Suitability of semen stress tests for predicting fertilizing capacity of boar ejaculates
Cold- and heat-resistance were dependent factors and sperm motility but neither semen stress test can be used as a sole test for predicting the fertilizing capacity of boar ejaculates.
Administration of cloprostenol to sows improves WSI and farrowing rate
The application of cloprostenol after farrowing improved fertility rates and reduced non-productive days.
Vaginal microbiota differences associated with pelvic organ prolapse risk during late gestation in commercial sows
Sows with greater pelvic organ prolapse risk have unique vaginal microflora.
Investigating pig survival in different production phases using genomic models
Survival is a complex trait with low heritability; however, important genetic gains can still be obtained, especially under a genomic prediction framework.
Evaluation of sow thermal preference across three stages of reproduction
The thermal comfort zone of sows may be narrower than current recommendations indicate.
Genomics of response to PRRSV: antibody response and performance following natural infection vs. vaccination
Selection for antibody response to PRRSV can increase litter size in purebred and commercial sows.
Vaginal microbiome and serum metabolite differences in late gestation sows at risk for pelvic organ prolapse
Sows with greater pelvic organ prolapse risk have differential serum metabolites and vaginal microflora.
Genetic parameters and associated genomic regions for global immunocompetence in pigs
Study results support the possibility of applying effective selection programs to improve immunocompetence in pigs.
How does inducing farrowing affect immunological parameters in colostrum?
When labour induction is applied, the questions arise about possible effects on labour and lactation, including colostral immunity.
Genomic analysis of IgG antibody response to pathogens in commercial sows
Results suggest that genetic selection of antibody response in commercial sows is possible, but with variable success.
Discovery of sex-determining region on pig Y chromosome may have applications in preventing boar taint
This discovery of SRY as the main switch for sex determination in pigs may provide an alternative for surgical castration in pig production, preventing boar taint.
Improvement of the motility of boar sperm after cryopreservation
When using thawing extender at pH 8, there was enhanced post-thawing sperm motility and preservation of motility as storage time advanced.
Impact of sperm concentration on sperm morphology
Ejaculates with a high sperm concentration contain a large number of sperm, but have a smaller volume than ejaculates with a lower sperm concentration.
Associations between foetal size and ovarian development in the pig
Postnatal differences in the reproductive potential of growth restricted females are programmed early in gestation.
Effect of different levels of taurine on boar semen quality
The proper addition of taurine to the semen extender suppresses sperm damage and subsequent dysfunction during liquid preservation.
