AI Article Synopsis
- The study analyzed serum samples from 18 free-ranging and 22 zoo-based koalas at San Diego Zoo to investigate their health.
- Key nutrients like calcium, chloride, molybdenum, selenium, and vitamin E were found in higher concentrations in zoo-based koalas, while free-ranging koalas had more magnesium, manganese, phosphorus, and zinc.
- No gender differences were observed, and the findings will help establish baseline nutrient levels for koalas in health assessments.
Article Abstract
As part of a health investigation on koalas at San Diego Zoo, serum samples were analyzed from 18 free-ranging and 22 zoo-based koalas, Phascolarctos cinereus. Serum concentrations of calcium, chloride, cobalt, copper, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, sodium, zinc, and vitamins A, E, and 25(OH)D3 were quantified. Calcium, chloride, molybdenum, selenium, and vitamin E concentrations were significantly higher in zoo-based koalas than in free-ranging koalas, whereas magnesium, manganese, phosphorus, and zinc concentrations were significantly higher in the free-ranging koalas. No significant differences were found between genders. The results from this study will help to establish a starting point for determining target circulating nutrient concentrations in koalas.
