The presence of bacteria in swine semen creates competition from nutrients with the sperm cells and results in metabolic byproducts that may harm the spermatozoa. Bacteria release toxins like lipopolysaccharides (LPS) during their life and multiplication, as well as when they die.

The presence of bacteria in extended boar semen is associated with decreasing semen quality and reproductive performance.

Currently, part of the bacteria-fighting solution is still the adding of antibiotics to extended semen. However, the bacteria present in swine semen are becoming more resistant to common antibiotics. It is therefore increasingly more common to use the latest generation of antibiotics or to increase the quantity in order to control bacterial development. Our goal is to provide an alternative to the latest generation of antibiotics.

We coated the inside of the BactiBag® with a special bacteriostatic molecule, called BactiGuard. When it comes into contact with bacteria, BactiGuard inserts itself into bacterial cell membranes and disrupts the membrane’s activities without causing a leak of intracellular components. The members are then more porous, which prevents the absorption of nutrients and bacterial growth. BactiGuard also blocks fatty acid biosynthesis, which is necessary for multiplication.

This process has two effects:

  • Significant slowdown of bacterial multiplication
  • Increase in bacterial membrane permeability (particularly Gram-negative bacteria) and therefore of the effectiveness of antibiotics.

BactiBag is part of a complete solution enabling you to prevent the growth of bacteria in swine semen. The method of collecting the semen is also very important. Discover Collectis, an automated collection system that provides the highest level of hygiene. Also discover NutriXcell Plus, our preservation medium that, used jointly with the BactiBag, enables you to significantly increase the mobility and viability of spermatozoa.

The BactiBag swine semen bag is designed for use on GTB 1000 V3 machines. It can be used with catheters for uterine or intrauterine insemination (post-cervical).
