The SERGA insemination centre distributes sperm doses in Spain since 1994 and offers a wide range of related services.

The best bucks of each line are selected by strict genetic and health controls and they are placed in production in our insemination centre.

We offer sperm doses from 4 different genetic lines: 2 meat lines and 2 maternal lines.

Sperm doses and formats

We provide sperm doses in various presentations:

– Pool: in a graduated container with several formats.

– Pool with ovulator (MRA-Bit system): they include the ovulator with the same formats.

– Single doses: prefilled and gelled individual cannulas, easy to apply.

Two ways of working together: delivery of sperm doses or application in the farm

For the convenience of our clients, at SERGA we adapt to all needs: we can deliver the sperm doses for an own application, or we can go to the farm and apply them ourselves.

Considerations before deciding on one option or another:

  • On the one hand, the process of applying sperm doses is delicate and susceptible to errors, such as mistakes in putting the photoperiod, inappropriate manipulations, application of the hormone and even bad techniques in the application of sperm doses.
  • On the other hand, the optimum choice is that the farmer knows how to apply the sperm doses perfectly. So, depending on the farm, its workforce, level of care with the applicators, etc. each farm can decide how to work with SERGA.
  • In some cases, the sperm doses must be applied by specialized staff, since other factors are valued in addition to the application itself.

In case of hesitation between one or another option, contact SERGA: we will be glad to advise you.
