Influence of vibration duration on the quality of boar semen doses packed in bags or tubes.

As previous data showing the negative impact of semen agitation during transport on sperm quality was obtained only in tube-type packages, this study aimed to compare two packages for boar semen dose (bag or tube) submitted to different agitation times. Ejaculates from thirty different boars were diluted in BTS extender, packed in bags or tubes in split sample, and submitted to agitation for 0, 6, or 12 h at 100 rpm at 17 ºC. Semen doses were stored for up to 168 h and evaluated for quality traits.

Artificial insemination and optimization of the use of seminal doses in swine.

The optimization of processes associated with artificial insemination (AI) is of great importance for the success of the pig industry. Over the last two decades, great reproductive performance has been achieved, making further significant progress limited. Optimizing the AI program, however, is essential to the pig industry's sustainability.
