Comparing methods of sex identification in Python brongersmai snakelets.
With the increment of exotic animal's trade in the pet business, the necessity of more studies in this area was observed. This study aimed at comparing different methods of sex identification in Python brongersmai snakelets (Bloody Python), using 14 baby snakes aged 1 year and 9 months approximately, from commercial breeding of wild and exotic fauna, situated in Cornélio Procópio - PR. Methods used were the probing technique introduction, measurement of snout-vent length, post-vent length, total length; ultrasound evaluation of reproductive organs and genetic profile exam (DNA samples), denoting the veracity of each one. A 100% efficacy was observed in the study of sexual determination through DNA samples, while the other methods were shown to be inconclusive, whilst the sexing scale count via the probing technique introduction and sexual dimorphism by bodily measurements permitted only a previous sexual classification, suffering variations when compared, showing to be inconclusive methods. The ultrasound evaluation was not efficient for the sexing process in snakelets aged approximately 1 year and 9 months in Python brongersmai.
