A novel approach to intrauterine viral inoculation of swine using PCV type 2 as a model.

Experimentally intrauterine (IU) viral inoculation has been commonly used to circumvent maternal interference with transplacental infection of fetuses and to assess the effect of viral infection on fetal development or reproductive parameters. However, IU inoculation requires surgical procedures such as laparatomy and surgical incision of the uterus. Post-surgical complications, that frequently result in abortion or fetal death, have been a major disadvantage.

Electrophoretic behavior and potency assessment of boar sperm using a capillary electrophoresis-laser induced fluorescence system.

The assessment of mammalian fertility, and the agents that affect it, is of increasing concern in medicinal, environmental, and agricultural science. The viability, integrity, and overall state of the male gamete (sperm) is an essential factor that must be considered in such studies. Traditional potency evaluations tend to be labor intensive and often are not precise.
