What Is Donkey Milk?
Donkey milk, also known as jenny milk or ass milk, is the milk produced by female donkeys (Equus asinus). This unique dairy product has been valued for thousands of years, dating back to ancient civilizations where it was prized for both its nutritional and cosmetic properties. Unlike conventional dairy products, donkey milk is produced in relatively small quantities due to the donkey’s small udder size, making it one of the most exclusive and expensive milk varieties available today.
The milk is characterized by its distinctive white color and smooth texture, with a composition that remarkably resembles human breast milk more closely than any other animal milk. This similarity has made donkey milk particularly valuable for infant nutrition and as an alternative for individuals with cow milk allergies. The production process requires specialized care and handling, as donkeys typically produce only 1-2 liters of milk per day, compared to the 20-40 liters produced by dairy cows.
Nutritional Composition and Profile
The nutritional profile of donkey milk sets it apart from other mammalian milks through its unique balance of macronutrients and micronutrients. The composition shows remarkable similarities to human milk, making it an exceptional alternative for those seeking nutritious dairy options.
Macronutrient Breakdown
Donkey milk contains a distinctive macronutrient profile characterized by low fat content (0.86%), moderate protein levels (1.5-2.03%), and high lactose content (5.75-7.4%). This composition differs significantly from cow milk, which typically contains 3-4% fat and lower lactose levels. The total protein content ranges from 1.5 to 1.8 grams per 100g, placing less strain on the renal system compared to higher-protein milk varieties.
The energy content of donkey milk is relatively low, providing approximately 40.39 kcal per 100g, making it an excellent choice for those monitoring caloric intake. The high lactose content contributes to the milk’s natural sweetness and enhances calcium absorption, which is crucial for bone mineralization, particularly in infants and growing children.
Protein Composition and Quality
The protein structure in donkey milk is particularly noteworthy for its hypoallergenic properties. The milk contains three primary proteins: α-lactalbumin, β-lactoglobulin, and lysozyme. Recent studies have revealed that α-lactalbumin possesses antiviral, antitumor, and antistress properties, adding therapeutic value to the milk’s nutritional benefits.
One of the most significant advantages of donkey milk is its reduced content of β-lactoglobulin, which represents approximately 40% of whey proteins compared to higher concentrations in cow milk. This protein is one of the main allergens affecting children, and its reduced presence makes donkey milk a suitable alternative for individuals with cow milk protein allergies.

Mineral and Vitamin Content
Donkey milk serves as an excellent source of essential minerals including calcium, phosphorus, magnesium, potassium, sodium, and trace elements such as iron, zinc, and copper. The mineral content, calculated as ash percentage, typically measures around 0.51%. The milk also provides significant amounts of vitamins A, B2, and C, contributing to its overall nutritional value.
Health Benefits of Donkey Milk
The health benefits of donkey milk extend far beyond basic nutrition, offering therapeutic properties that have attracted increasing attention from healthcare professionals and nutritionists worldwide.
Hypoallergenic Properties
One of the most significant health benefits of donkey milk is its hypoallergenic nature. The milk contains lower percentages of potent allergens such as β-lactoglobulin and αS-1 casein compared to cow milk. This reduction in allergenic proteins makes donkey milk suitable for consumption by infants, children, and adults who suffer from cow milk protein allergies or lactose intolerance.
The casein-to-whey protein ratio in donkey milk (70.3:100) falls between that of cow and human milk, providing a balanced protein profile that is easier to digest. This characteristic makes it particularly valuable for individuals with sensitive digestive systems or those recovering from gastrointestinal disorders.
Immune System Support
Donkey milk contains natural antibacterial compounds and enzymes that contribute to immune system support. The presence of lysozyme, an enzyme with antimicrobial properties, helps protect against bacterial infections and supports overall immune function. The milk’s natural antibacterial action results in significantly lower microbial counts compared to milk from other dairy animals.
Digestive Health Benefits
The high lactose content in donkey milk, while initially seeming problematic for lactose-intolerant individuals, actually facilitates better intestinal absorption of calcium. This enhanced absorption is essential for proper bone mineralization and development, particularly important for infants and growing children. The milk’s alkaline pH (7.2-7.5) also contributes to better digestive tolerance compared to more acidic milk varieties.
Skin and Cosmetic Benefits
Historical and modern applications of donkey milk in cosmetic treatments stem from its moisturizing and anti-aging properties. The milk’s composition, rich in vitamins and minerals, helps maintain skin hydration and elasticity. The proteins and amino acids present in donkey milk contribute to skin repair and regeneration processes.
