Sexing of parrots
| Sexing of parrots
Male or female: Is this really what you know about a parrot? Most of the more than 330 species of parrots and Sittichen are monomorph, ie there are no clear signs of external male or female sex. These types have owners and breeders for many years tried to close the gender of their Pfleglinge with the help of so-called secondary sexual characteristics such as size of the bird or individual body parts, on the basis of color nuances and practices. The result of these efforts was often wait years to a clutch of a couple consisting of one large and one small male or a fertilised eggs from 2 kopulierenden and eierlegenden females. The clear, definite sex determination to play in the maintenance and breeding of parrots play a central role. Alluding to the situation in the wild parrots is in keeping with the welfare friendly attitude pairs of males and females of the same species or subspecies. For some, tolerated species groups can also be established permanently, in which a balanced sex ratio of males and females there. Among the various methods of sex determination in parrots and the endoscopic Sittichen have sex determination with organ investigation and the genetic sex determination the greatest practical relevance.

Genetic sex determination by analyzing the DNA from a spring or blood sample |
Blood from the neck vein (Vena jugularis) for most chicks from 10 day life feasible Sample extraction (feathers or blood) of parrots raised by parents can also can be taken out in the nesting box. No significant sampling risk
|
Limited power (only indication male or female as a test result) Not a 100% certainty of the outcome (due to laboratory or sample) Easy to manipulate (intentional or unintentional false labelling for submission of samples by the bird owners without control of a neutral person such as a veterinarian) So far not yet reached all parrots and parakeets No statement about breeding condition Not suitable as buying investigation When sending samples from birds can usually only small quantities of DNA isolated. A storage of DNA for later controls (for example because of manipulation of the identification of the sample) is therefore not possible. Results are not immediately, but only after 5-14 days

Endoscopic sex determination with organ examination: The bird is produced by a short inhalation anesthetic stunned. By about 3 mm short skin and muscle cut is behind the last rib an endoscope into the abdominal cavity of the bird introduced and the visible institutions such as air bag, lungs, liver, stomach glands, kidneys, the adrenal gland, spleen, intestinal loops, ureter, fallopian tubes, and the Geschlechtsdrüse investigated and assessed.

Sex determination in principle on all bird species. Sex determination in most parrots and Sitticharten from the age of 6 weeks (for Handaufzuchten) feasible. By endoscopic presentation of the testes or ovary 100% safe sex determination. Due to the assessment of the state of internal organs and the exterior of the bird as a purchase or inquiry to assess the quality of the bird. Examination of the internal organs and allows the exterior disease diagnostics such as Verpilzung, ovarian cysts, air bag inflammation, and many others Verfettung Assessment of the breeding condition, taking account of the development and circulatory condition of Geschlechtsdrüse and other relevant institutions. Lasting Gender identification by tattooing after endoscopy under the wing (right male, female left). Very low anesthesia and surgery risk, if by an experienced surgeon carried out (at own results, the Aufwach rate from the anesthesia after endoscopy at 99.98%.) Acceptable in the context of the home directly from the breeder or keeper carried out so that the transport of birds for the investigation is not necessary. As part of the anaesthetic for endoscopy can also identify the microchip identification of the bird for uniquely identifying carried out. The owner immediately know the results of endoscopy and in the case of diseases can be immediately diagnosed with the therapy started.

If the bird is extremely fat or with animals of strong air bag inflammation sex determination is not feasible. Years of experience and almost daily practice of the surgeon for a perfect implementation of endoscopy. Therefore, relatively few specialists. For inexperienced operators and application of immature techniques is a certain anesthesia, surgical and risk of infection.

The table shows that the genetic sex determination is very well suited for private owners, a single bird, and only want sex without wanting to breed, and are not interested in the state of the internal organs of the bird to learn. It recommends also for farmers, for their own breeding planning at the sex nestlings want to know. The genetic sex determination - on the basis of the diverse ways by manipulation of the sender and the low strength of the animal itself - less suitable for the detection of sex in young animals or Altvögeln, sold to third parties. In this area there are significant advantages of the endoscopy: a thorough internal and external examination by a neutral and competent avian veterinarian guaranteed maximum objectivity in the evaluation of the quality, breeding condition and general health status of the investigated bird and brings clarity to the buyer and seller of the bird, just like for the breeder of this animal in the breeding would like to use or want to know whether the bird is already zuchtreif. The practical use of endoscopic sex determination with organ investigation in many years as individual birds animals in private households has shown that most private keeper of the bird in this way never before had investigated and no findings on the state of the internal organs of their bird. Often they believe that their animal in perfect health, since he so far has been discreetly, and are very surprised if findings such as air bag inflammation, fungal statement, fat liver with diminishment or enlargement and evidence to suggest a significant metabolic disorders will be presented . Because of the wide range of diagnostic results at the relatively simple and straightforward method of endoscopy is something for all owners of parrots and parakeets advisable to its bird at least once in this way to investigate. Parrots breeding maturity or Sittichpaare, in the last 2 years gebrütet, should help to clarify the possible cause, in any case, an endoscopic examination with sex organ evaluation.
