  • Antillen-Ochsenfrösche werden zur Wiederauswilderung in Gefangenschaft gezüchtet. Dabei treten häufig Probleme bei der Knochenbildung auf. Röntgenaufnahmen bei jungen Fröschen, die ohne UVB-Bestrahlung aufgezogen wurden, zeigen das.
  • Frösche, die mit UVB-Bestrahlung nach Ferguson-Zone 2 (Gradient von UV-Index 0 bis UV-Index 3) haben ein normal entwickeltes Skelett (Röntgenuntersuchung). Die Frösche wurden dabei zunächst in Terrarien der Größe 46cm x 30cm x 17cm mit einer 1,150mm Arcadia T5-HO D3+ 12% UVB  Röhre gehalten, später in Terrarien der Größe 2m x 2m x 3m mit UVB-Rlhre in Kombination mit einer 300W Osram Ultravitalux.

Abstract
Conservation breeding programmes are a tool used to prevent amphibian extinctions. The husbandry requirements of amphibians are complex. Ongoing research is needed to ensure optimal management of those captive-bred animals destined, in particular, for reintroduction. The UV-B and vitamin D3 requirements of amphibians are largely unknown. Metabolic bone disease has been reported in a number of species. These include the Critically Endangered mountain chicken frog (Leptodactylus fallax) reared in captivity on diets supplemented with a high-calcium multivitamin and mineral supplement containing vitamin D3 but without UV-B provision. Captive-bred L. fallax being reared for reintroduction to Montserrat were provided with UV-B radiation from metamorphosis and were fed on insects supplemented with vitamins and minerals. Overlapping heat, light and UV-B gradients were provided, mimicking what we believe best represents the natural situation and thereby facilitated self-regulation of UV-B exposure. A subset of 10 frogs was periodically radiographed to assess skeletal health. Radiographic bone density and anatomical integrity appeared unremarkable when compared with a wild caught L. fallax. In addition to other routine health-screening, we recommend that radiography be performed to a structured schedule on a subset of all captive-bred and reared amphibians to assess skeletal health and to gauge the appropriateness of captive husbandry. We demonstrate here that, through the appropriate provision of a combination of both UV-B radiation and dietary supplementation, L. fallax can be bred and reared in captivity with healthy skeletal development.
