Encapsulated porcine semen: semen preservation, release kinetics, sperm transport, and results in the farm
Sows inseminated with encapsulated semen had more sperm cells concentration at the site of fertilization.
Sex pre-selection of the offspring by using X or Y chromosome bearing spermatozoa sorted by flow cytometry
The main objective of this thesis was to develop a protocol to efficiently apply flow cytometric sex-sorting procedure on boar spermatozoa.
Benefits of semen encapsulation to swine artificial insemination
Encapsulation allows to reduce the dose per sow and a sequential release of sperm.
Planning gilt service
The strategy involves synchronizing the gilts so they come into heat at the same time, in order to properly manage the number of inseminations targeted for each lot.
Use of paternity tests in swine
These tests have several practical applications, as the detection of boars that are linked to the appearance of hernias or the susceptibility towards certain enteric diseases or even syndromes like the PFTS.
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.
