Compounds from multilayer plastic bags cause reproductive failures in artificial insemination
This is the first described relationship between reproductive failure and toxic compounds released from plastic bags.

PRRSV transmission via boar semen
Monitoring protocols in boar studs are often insufficient to timely detect an infection.
The battle of the sexes starts in the oviduct: modulation of oviductal transcriptome by X and Y-bearing spermatozoa
Data suggest that the oviduct functions as a biological sensor that screens the spermatozoon, and then responds by modifying the oviductal environment.
Swine artificial insemination: which technique to use and how many sperm per dose?
We should be cautious when setting the number of sperm per insemination dose, so the urge to reduce it does not make us use a number that is under the fertility threshold. Something that may be productive and/or profitable for a certain farm may not be so for another farm.
Supplementing cryopreservation media with reduced glutathione increases fertility of sows
Supplementing freezing media with 2 mm GSH greatly improves boar sperm cryopreservation technology, as it significantly improves the fertilizing ability of frozen-thawed spermatozoa.
Sino-French agreement in the agriculture and agri-food sectors
This agreement will strengthen the pig meat, fowl and wine exports.
Colombia and Canada reaffirm sanitary and phytosanitary agreements
During the committee, punctual agreements were established in order to make progress in the importation of animals and genetic material of the swine and ovine species.
Reproduction in gilts inseminated with PCV2-spiked semen. Protection by gilt vaccination with a sow PCV2 vaccine
PCV2 vaccination of the gilts prior to insemination with PCV2 spiked-semen showed a clear decrease of viral load in the gilts as well as a much lower viral excretion that were compatible with foetus protection.
Genetic parameters for male fertility and its relationship to Skatole and Androstenone in Danish Landrace Boars
These data suggest that concentrations of skatole and androstenone can be reduced through genetic selection without negatively affecting important male fertility traits in Danish Landrace pigs.
Simplified freezing of boar semen: possible?
Novel cryopreservation methods and containers are designed to increase semen cryosurvival without disturbing production of conventional liquid semen doses. This provides opportunities for gene banking and preserved fertility when inseminated deep intra uterine, alongside undisturbed commercial AI-dose production.
Pre-freezing and post-thawing quality of boar sperm for distinct portions of the ejaculate and as a function of protein bands present in seminal plasma
This study evaluated pre-freezing and post-thawing boar sperm quality in distinct portions of the ejaculates and identified protein bands potentially related to boar sperm tolerance to freezing.
Ireland: PRRS outbreak
The country’s largest producer of pig semen is investigating how blue ear disease has entered its boar stud.
Danish pig meat exports declined during 2012
With pig slaughtering declining by over 1m head during 2012 (from 20.4m to 18.9m), it was no surprise to see a decline in exports of Danish pig meat over the year.
Effect of dietary selenium on boar sperm quality
Supplementing a basal diet with organic or inorganic selenium did not affect semen quantity or sperm quality in fresh ejaculates.
