As the summer temperatures rise across South Africa, aviaries are buzzing with breeding activity, and that means it’s also the time to stay alert for Psittacine Beak and Feather Disease (PBFD) and to confirm your birds’ sex through DNA testing before pairing.
Why Test Now?
Warmer weather and closer contact during the breeding season increase the risk of virus transmission. PBFD, a highly contagious circovirus that affects parrots and related species, damaging feathers, beaks, and immune systems. Once introduced, it can quickly spread through feather dust, faeces, or contaminated surfaces.
Testing before breeding, trading, or introducing new birds is the best way to protect your flock and ensure the next generation of chicks stays healthy.
PBFD Testing at Envirocare Laboratory
At Envirocare Laboratory, we use molecular PCR methods to detect PBFD virus DNA from feathers or blood samples, giving you fast and reliable results.
- Detects infection early — even before symptoms appear
- Helps prevent spread between breeding pairs
- Essential for flock health management
Avian Sexing – Plan Your Pairings with Confidence
Many parrot species show no visible gender differences, making DNA testing the most accurate way to identify males and females.
DNA sexing supports:
-
Better pairing and breeding success
-
Genetic diversity in your aviary
-
Behavioural understanding and management
A small feather or blood sample is all it takes to give you clarity this breeding season.
Stay Ahead This Summer
As temperatures climb:
-
Test all breeding birds for PBFD
-
Confirm sex before pairing
-
Keep aviaries clean and well-ventilated
-
Quarantine any new birds
Take proactive steps now to ensure a healthy, productive breeding season.
