Koala milk may hold key to better care for orphaned joeys

Phys · · 503 words · By Edith Cowan University

Researchers from Edith Cowan University and other Australian institutions have studied how koala milk composition changes during lactation to support joey development. The findings aim to improve synthetic milk substitutes for orphaned koalas in rehabilitation centers.

“The study, led by Edith Cowan University (ECU) Ph.D. candidate Manujaya W. Jayamanna Mohottige, is part of a larger project on koalas and their survival led by the Australian Wildlife Genomics Group at The University of Sydney and the Australian Research Council Center of Excellence for Innovations in Peptide and Protein Science.”
CORROBORATED
Web search results confirm Manujaya W. Jayamanna Mohottige is a PhD candidate at Edith Cowan University (ECU) specializing in proteomics and investigating marsupials/koalas. Multiple search results link him to research on the pouch environment and milk.

“Unlike human milk, marsupial milk is known to change its composition over time to meet the joey's evolving growth and immune needs.”
VERIFIED BY REFERENCE
A review of marsupial and monotreme milk explicitly states that macronutrient energy composition changes concentration during the course of lactation and supplies growth and immune factors, distinguishing this dynamic process from the relatively more stable composition of human milk described in the breast milk Wikipedia entry.

“Professor Michelle Colgrave from ECU's School of Science said koalas faced many threats, including bushfires, road accidents, disease and habitat loss.”
CORROBORATED
The Nature Genetics result confirms that koalas are classified as 'vulnerable' due to habitat loss and widespread disease. General knowledge of koala conservation (though the specific quote from Prof. Colgrave isn't in the snippets) aligns with the documented threats of habitat loss and disease.
