What Is Really in Donkey Milk?
From lactose and milk proteins to lysozyme and minerals: a science-based journey through the composition of an extraordinary milk.
One Milk. Many Components.
Donkey milk consists mostly of water. The remaining components—including lactose, fat, proteins, minerals, and vitamins—shape its taste and nutritional properties.
What makes donkey milk special is not a single "miracle substance," but its specific composition. Compared to whole cow's milk, it is typically lower in fat and protein but contains more milk sugar. The distribution of milk proteins also differs.
Donkey milk typically contains about 0.3–1.8% fat, 1.4–2.0% protein, and 5.8–7.4% lactose. These ranges come from scientific review articles; actual values vary depending on the animal, feeding, and stage of lactation.
Below, we take a closer look at the individual components—while consistently distinguishing between measurable composition and health claims, for which independent clinical evidence would be required.
The Anatomy of a Drop
An illustrative visualization of the typical composition. The bars represent approximate ranges from the literature, not a laboratory analysis of a specific batch.
The scales show mass percentages; smaller values appear correspondingly narrow. Ranges from the literature should not be understood as simultaneously exact sum values.
Why Does Donkey Milk Taste So Mild?
An important component is lactose, the natural milk sugar. Donkey milk contains more lactose on average than cow's milk. This contributes to its slightly sweet flavor profile, although temperature and processing affect perception.
For those with lactose intolerance, this difference is relevant: Donkey milk is not lactose-free and is not automatically better tolerated. People with a cow's milk protein allergy should also not consider donkey milk a safe substitute on their own.
For comparison: cow's milk typically contains around 4.6–5.0 g of lactose per 100 ml; for donkey milk, approximately 5.8–7.4 g is often stated. You can find an overview of other types of milk at Which Milk Contains How Much Lactose?
Milk Proteins: More Than Just a Number
Not only the quantity, but also the composition of the proteins distinguishes donkey milk from cow's milk.
Caseins
Caseins form complex structures in milk and are particularly important for cheese making. Donkey milk contains less casein overall than cow's milk.
Whey Proteins
The whey protein fraction includes various proteins. Its relative ratio to the caseins differs between the types of milk.
Other Proteins
Scientifically studied components include lysozyme and lactoferrin. Their concentrations vary; their presence is not clinical evidence of efficacy.
In food science, such differences are investigated using analytical methods. However, the fact that a milk contains certain proteins does not automatically allow one to infer what effect its consumption has on humans.
Lysozyme and Lactoferrin: What Does Research Say?
Lysozyme is an enzyme that can break down certain bacterial cell wall components. It is regularly studied in donkey milk. Lactoferrin is an iron-binding protein that is also the subject of food science research.
Crucial factors include concentration, processing, digestion, and whether reliable human studies exist for a specific endpoint. Laboratory findings and animal studies may therefore not be equated with clinically proven effects.
We therefore make no statements about the health effects of donkey milk. Donkey milk is a food and not a medicine.
Less Fat—But What Does That Mean?
The fat content of donkey milk is typically lower than that of whole cow's milk. This can also result in a lower energy content. However, the comparison depends on the fat content of the cow's milk: skim milk also contains very little fat.
Fat is not the only source of energy. Lactose and protein also contribute calories. Therefore, nutritional values should always be viewed as a complete profile.
For precise product labeling, a batch- or product-specific nutritional analysis is more meaningful than a general average from the literature.
Donkey Milk and Whole Cow's Milk Compared
| Characteristic (approx. per 100 ml) | Donkey Milk | Whole Cow's Milk |
|---|---|---|
| Fat | 0.3–1.8 g | 3.5–3.8 g |
| Protein | 1.4–2.0 g | 3.2–3.5 g |
| Lactose | 5.8–7.4 g | 4.6–5.0 g |
| Energy | approx. 35–60 kcal | approx. 63–68 kcal |
| Taste | Mostly mild, slightly sweet | Mostly mild, creamier |
| Availability | Specialized retailers | Broader food trade |

Vitamins and Minerals
Donkey milk contains minerals such as calcium, phosphorus, potassium, and magnesium, as well as various vitamins. The actual contents vary depending on feeding, season, animal, and processing.
A blanket statement such as "exceptionally rich in vitamins" would be inaccurate without a concrete basis for comparison. Similarly, no special health effects can be inferred from the mere presence of individual vitamins.
Crucial are the actual amount contained per 100 ml or serving, the analytical method used, and, if applicable, the percentage of a recognized reference value. Only then can different products be fairly compared.
From Milk to Product Form
The composition of the raw milk is only part of the story. Storage and processing also determine how a product is offered and used.
01 — Extraction
The milk is obtained as part of specialized donkey farming. Milk volume and composition can vary between animals and at different times.
02 — Cooling and Transport
Maintaining suitable temperature conditions is particularly important for perishable foods.
03 — Fresh or Freeze-Dried Form
DON DONKEY'S® offers donkey milk delivered frozen as well as freeze-dried donkey milk powder. During freeze-drying, water is removed; the nutritional values of the powder therefore refer to a different reference quantity than liquid milk.
04 — Preparation
The respective product and storage instructions are decisive. Please follow the instructions on the label. Fresh donkey milk is stored at −18 °C and thawed slowly in the refrigerator at 2–7 °C.
Frequently Asked Questions About the Ingredients
What ingredients are contained in donkey milk?
Above all water, lactose, proteins, fat, minerals, and vitamins. Individual protein fractions such as lysozyme and lactoferrin are also scientifically studied.
Is donkey milk lactose-free?
No. It usually contains even more lactose than cow's milk.
How much protein does donkey milk contain?
Review articles often state approximately 1.4–2.0 g of protein per 100 ml. Individual samples may vary.
Does donkey milk contain lysozyme?
Yes, lysozyme is described as a component of donkey milk. However, this does not automatically mean a proven health effect in humans.
What vitamins does donkey milk contain?
Various fat- and water-soluble vitamins are described in the literature. The amounts depend on factors including feeding and processing; analyses are crucial for concrete information.
Is donkey milk suitable for people with a cow's milk protein allergy?
This cannot be answered blanketly. Donkey milk contains its own milk proteins and is not generally a safe substitute. Professional clarification is necessary.
Can donkey milk replace infant formula?
No. It is not a substitute for breast milk or approved infant formula.
How does donkey milk powder differ from fresh donkey milk?
Yes, particularly in water content and handling. The reference quantity must be considered for nutritional comparison.
The Uniqueness Lies in the Overall Picture
Donkey milk is interesting not because of a single ingredient, but because of its characteristic combination of milk sugar, fat, proteins, and other components.
Those who compare it with cow's milk discover differences in nutritional values, taste, and production. Scientific research also investigates individual molecules and protein fractions—without this automatically resulting in concrete health promises for the product.
A factual consideration therefore combines three things: measured values, classification, and verifiable sources.
