Composition of donkey milk: a review from Serbia

This review from Novi Sad (Serbia) summarises what is known about the composition of donkey milk: low in fat, cholesterol, total protein and casein, but high in lactose, whey proteins, calcium, selenium and vitamin D3. According to the authors, literature values for individual components differ considerably. They consider clinical trials in humans necessary for statements on health properties.

Important: A review without its own measurements, assessed based on the abstract. The biological activities it mentions do not demonstrate any effect in humans. Donkey milk is not a substitute for breast milk or infant formula; infant feeding belongs in medical hands.

Study design

How it was studied

Review by four authors from the Scientific Veterinary Institute “Novi Sad” (Serbia), funded according to the metadata by non-US public sources. It summarises literature on the chemical composition of donkey milk, protective proteins and biological activities described in the literature, and addresses commercialisation and research needs. The paper contains no own measurements. Assessed based on the abstract; specific contents, the studies included and how they were selected are not stated there.

Results

What the study measured

01

According to the authors, literature values for individual components of donkey milk differ considerably. As established basic characteristics they name low fat, cholesterol, total protein and casein, and high lactose, whey proteins, calcium, selenium and vitamin D3.

02

The review lists α-lactalbumin, lysozyme, lactoferrin, lactoperoxidase and immunoglobulins as protective proteins.

03

The authors list a range of biological activities described in the literature, such as antioxidant and antibacterial ones. The abstract does not state which types of studies these are based on; effects in humans are not demonstrated by them.

04

Because of the low total fat content, donkey milk must be enriched with other fat for children’s diets to provide enough energy, according to the authors.

05

Commercialisation of donkey milk is limited by low production, few products and a lack of product information.

06

The authors call for clinical trials in humans to obtain stronger evidence on the properties described.

Authors’ conclusion: Donkey milk has a valuable nutrient composition and can be considered a “functional food”; however, clinical trials in humans are needed for stronger evidence. The review describes composition – it does not show health effects in humans, and the classification as a functional food is the authors’ assessment.

Critical appraisal

Strengths and limitations

Evaluative statements without evidence in the abstractClear limitation

The abstract lists many “strong” activities without naming study types. We do not adopt such assessments.

No systematic method apparentNote

Search strategy and selection criteria are not described in the abstract. It is a narrative review.

Large variation in contentsNote

The authors themselves stress that literature values differ considerably. General statements do not apply to every milk.

Only the abstract assessedNote

Specific contents, sources and tables are unknown without the full text.

Names research needsStrength

The authors openly state that clinical trials are lacking and also name the low fat content as a limitation for children’s diets.

clear limitationnotestrength

Editorial note: The review confirms the known basic features of donkey milk composition and names the need for human studies. The list of biological activities in the abstract, by contrast, is a compilation of literature statements, not proof of effect. Donkey milk is not a substitute for breast milk or infant formula; infant feeding belongs in medical hands. To the research archive.

Research question for DON DONKEY’S®

How much do fat and lactose content of our donkey milk vary between batches and seasons – and can the values be stated on the label as an honest range?
