GFS congenital defect testing

GFS has been testing its boars for congenital anomalies since 1980 so that the boars can be selected to rule out genetic defects.

Based on litter reports provided by our member farms, GFS has issued what is known as a congenital anomaly rate for its boars.


Conditions to take part in the congenital defect investigation via sow planner:

- Performing inseminations from a single boar

- Entering the HB (herd book) number of the boar in the sow planner

- Entering the anomalies based on defined anomaly codes

There are three ways to submit a litter report:


Report by sow planner using AgriSyst

Automated transmission of congenital defect data

⇒ GFS covers the costs for regular evaluations

for insemination, for farrowing and for weaning (sow monitor)



Report by fax

Participating sow farmers fill in a form

Fax the data: as a congenital defect fax to GFS

Report by sow planner

Data backup or list export by email

The GFS congenital anomaly rate in the boar data sheet

  • The breeding values for anomalies is calculated in collaboration with the Animal Breeding Institute at the University of Bonn
  • Boars with at least 25 litters and a breeding value of -0.12 are culled
  • The most common anomaly is testicular / inguinal hernia


GFS is the only artificial insemination station that calculates and verifies congenital anomaly breeding rates for its boars.
This means that boars susceptible to anomalies can be selected and culled.

Would you like to help us detect congenital defects or are you interested in regular assessments

(farm evaluation during servicing, farrowing and weaning) known as the sow monitor from Agrisyst?

In appreciation of the support in detecting congenital defects, GFS covers the cost of the Agrisyst reports.
