Abstract


Most lovebirds (Agapornis spp.) have no distinct sexual dimorphic traits. The objective of the paper was to compare the results of two sexing methods, surgical sexing by celioscopy and DNA sexing by PCR from blood samples, in order to evaluate their effectiveness. Materials used to carry out the studies were a 2.7 mm telescope and endoscopy unit, surgical instruments and DNA sampling kits provided by Exomed.cz laboratory. Forty-two lovebirds were included in this study. The endoscopic sexing procedure was performed by the method described by Divers. Blood sampling for DNA testing by PCR method was performed from the metatarsal vein. The results were different in the case of one lovebird, endoscopic sexing revealed it as male, compared to DNA testing, where it was identified as female. DNA sexing is a non-invasive method that might be more accurate than celioscopy in this species, and bird owners have easier access to it.
