ARTIFICIAL ULTRAVIOLET B RADIATION RAISES PLASMA 25-HYDROXYVITAMIN D CONCENTRATIONS IN BURMESE PYTHONS ( PYTHON BIVITTATUS).

Deficiency of vitamin D can contribute to health complications that present as metabolic bone disease. The aim of this small-scale study was to determine if a high UVb irradiance would affect an increase in plasma vitamin D concentrations in Burmese pythons ( Python bivittatus). There have been inconsistent results throughout the literature concerning the usefulness of UVb radiation regarding vitamin D synthesis.

PLASMA CONCENTRATIONS OF VITAMIN A, B, D, AND E IN HUMBOLDT PENGUINS ( SPHENISCUS HUMBOLDTI) BEFORE AND AFTER DIETARY VITAMIN SUPPLEMENTATION OF THEIR FISH DIET.

In a practical feeding trial at Ouwehand Zoo, plasma concentrations of vitamin A, calcidiol (D), α-tocopherol (E), and B in 17 Humboldt penguins ( Spheniscus humboldti) were measured before and after supplementation to gain insight into the effect of supplementing these vitamins in animals being fed thawed frozen-fish diets. None of the penguins received vitamin supplements for at least 6 mo before the supplementation trial, which was conducted prior to their normal nesting and molting period. During the trial period, eight penguins received daily vitamin A, D, tocopheryl acetate, and B supplementation placed in their fish immediately prior to feeding and nine control penguins received no supplementation.

CONGENITAL NUTRITIONAL MYODEGENERATION (WHITE MUSCLE DISEASE) IN A GIRAFFE ( GIRAFFA CAMELOPARDALIS) CALF.

It is well known that vitamin E and selenium deficiencies in domestic ruminants can lead to white muscle disease. After a clinically normal gestation period at Ouwehand Zoo in the Netherlands, a newborn giraffe ( Giraffa camelopardalis) calf showed clinical signs of white muscle disease almost immediately after birth. The calf was rejected by the mother and was euthanized 3 days later because of deterioration of clinical signs.

Clinical outbreak of babesiosis caused by Babesia capreoli in captive reindeer (Rangifer tarandus tarandus) in the Netherlands.

From a herd of captive reindeer (Rangifer tarandus tarandus) consisting of two males and seven females with five calves, three calves were diagnosed on post mortem examination with a Babesia capreoli infection. The diagnosis was indicated by PCR and when the other reindeer were examined two adult females and a one-year-old male were Babesia-positive. Molecular characterization of the 18S rDNA of the parasite showed complete identity with known B.

Herpes simplex infection in a juvenile orangutan (Pongo pygmaeus pygmaeus).

A juvenile orangutan (Pongo pygmaeus pygmaeus) died after 8 days of diarrhea and vomiting. Necropsy showed petechial hemorrhages in the skin, the myocardium, and the peritoneal membranes. The lungs were hyperemic and edematous, and the liver and spleen were enlarged.
