Hematologic and Serum Biochemical Reference Intervals for the Bilby (Macrotis lagotis)

Area of Science:

• Veterinary Medicine
• Wildlife Conservation Biology
• Zoology

Background:

• The bilby (Macrotis lagotis) is an endangered Australian marsupial.
• Establishing species-specific reference intervals is crucial for health monitoring and conservation efforts.
• Limited hematologic and biochemical data exist for bilbies.

Purpose of the Study:

• To establish hematologic and serum biochemistry reference intervals for the bilby (Macrotis lagotis).
• To identify factors influencing these parameters, including age, sex, and environment (captive vs. free-ranging).
• To provide essential data for the health and conservation management of this endangered species.

Main Methods:

• Blood samples were collected from 135 bilbies.
• Animals were sourced from a captive breeding colony and a free-ranging exclosure.
• Hematologic and serum biochemistry analyses were performed.
• Statistical analyses were used to compare parameters across different groups.

Main Results:

• Reference intervals for key hematologic and serum biochemistry parameters were determined.
• Significant differences in parameters were observed based on animal age.
• Sex and captive versus free-ranging status also influenced biochemical and hematologic parameters.

Conclusions:

• Established reference intervals provide a vital baseline for bilby health assessment.
• Understanding variations related to age, sex, and environment is critical for accurate health monitoring.
• These data will support effective conservation and veterinary management strategies for the endangered bilby.
