Analysis of hygienic critical control points in boar semen production

The present study emphasizes the need for both training of the laboratory staff in monitoring HCCP in routine semen production and audits in such AI centers for the external control of hygiene parameters.

Porcine semen as a vector for transmission of viral pathogens

Prevention of viral semen contamination should be the primary focus because it is easier to prevent contamination than to eliminate viruses once present in semen.

Influences on semen traits used for selection of young AI boars

A minimum age is proposed for young boars to qualify for selection, or alternatively, age-related semen quality thresholds in young boars should be established.

The use of oxytocin in liquid semen doses to reduce seasonal fluctuations in the reproductive performance of sows

On the basis of the presented results, it should be noted that the use of oxytocin into insemination doses improves the farrowing rate and other parameters of the reproductive performance of sows.

The effect of numbers of frozen-thawed boar sperm and addition of prostaglandin F2α at insemination on fertility in pigs

These results indicate that AI using 2.0 × 109 FTS can result in acceptable pregnancy rates and litter sizes but with no measurable benefit for addition of prostaglandin.

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.

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.
