Ologies with Alie Ward

Asinology (DONKEYS) with Faith Burden

January 28, 2026

Key Takeaways Copied to clipboard!

  • Donkeys are highly intelligent, thoughtful animals whose perceived stubbornness stems from an evolutionary adaptation to freeze or fight rather than flee danger, unlike horses. 
  • The ancestor of the donkey originated in the deserts and mountains of East Africa, leading to adaptations like large ears for heat dissipation and a highly water-retentive hoof structure that makes them susceptible to foot problems in damp climates. 
  • Mules, the sterile hybrid of a horse mother and a donkey father, possess 'hybrid vigor,' combining the size and speed of a horse with the toughness and calmness of a donkey, making them excellent sure-footed working animals. 
  • Donkeys possess innate adaptation for dangerous environments, evidenced by mules being preferred for work in places like the Grand Canyon due to their short-footedness. 
  • Donkey load-carrying capacity varies significantly by research, ranging from 28% to 50% of body weight, though some heavy labor has seen them carry up to 120%, which is linked to back issues. 
  • Essential care for donkeys includes ensuring they have companionship (never keep one alone), providing dry shelter from poor weather, avoiding rich feeds like those for horses, and dedicating time for bonding and observation to catch early signs of illness. 

Segments

Donkey Origins and History

(00:03:46)
  • Key Takeaway: The donkey’s ancestor is the wild African ass, domesticated about 7,000 years ago in East Africa.
  • Summary: Donkeys originated in the mountains and deserts of Ethiopia, Eritrea, and Sudan. They were domesticated around 7,000 years ago and later became crucial in ancient Egyptian society, initially used for meat and milk before becoming respected ceremonial animals. Donkeys reached the Americas relatively recently, around the 15th century.
Evolutionary Adaptations: Ears and Sociality

(00:06:51)
  • Key Takeaway: Donkey ears are large to dissipate heat and facilitate long-distance communication, as their ancestors lived alone or in very small groups, unlike horses.
  • Summary: The large ears are an adaptation for desert survival, helping to regulate body temperature. Their bray is exceptionally loud, traveling for kilometers, which is necessary for communication in solitary or small group settings. Donkeys stand and consider threats rather than immediately running away, which contrasts with the herd behavior of horses.
Sanctuary Size and Welfare Issues

(00:07:48)
  • Key Takeaway: The Donkey Sanctuary currently owns 6,200 donkeys, many rescued from neglect, abandonment, or owners outliving their long lifespan.
  • Summary: The sanctuary cares for thousands of donkeys, including those with medical or behavioral issues. A major international concern is the harvesting of donkey hides for gelatin, leading to up to 4.8 million deaths annually, which the sanctuary actively researches and advocates against. Donkeys often outlive their owners, presenting a long-term commitment challenge for caregivers.
Guest Background and Myth Busting

(00:11:50)
  • Key Takeaway: The primary myth that donkeys are stupid or stubborn is false; their behavior is rooted in thoughtful self-preservation, contrasting with the flight response of horses.
  • Summary: Dr. Burden transitioned from a background in microbiology and virology to donkey welfare research over two decades ago. Donkeys assess situations before acting, leading to behaviors misinterpreted as stubbornness when compared to the expressive, fast-running nature of horses. Their calm, thoughtful nature makes them ideal for carrying precious cargo safely.
Donkey Emotions and Communication

(00:19:40)
  • Key Takeaway: Donkeys are highly emotional, exhibiting strong pair-bonding and grief, and their vocalizations (bray, snorts, whiffles) convey specific meanings recognizable by experienced carers.
  • Summary: Donkeys express excitement upon reuniting with loved ones, but their day-to-day behavior is subtle due to desert adaptations requiring energy conservation. Their sense of smell is crucial for territorial marking, often involving the Flehmen reaction (curling the upper lip) to draw scents into the vomeronasal organ. They enjoy novelty and will play with items like rubber boots or large balls.
Mule Genetics and Characteristics
Copied to clipboard!
(00:25:01)
  • Key Takeaway: Mules result from a horse mother and donkey father, possessing hybrid vigor that grants them increased size and speed over donkeys, combined with donkey toughness.
  • Summary: Mules are sterile because horses have 64 chromosomes and donkeys have 62, resulting in an uneven number in the offspring. They are highly intelligent and trainable but require consistent, fair handling, as they do not easily forgive poor treatment. Mules are historically vital in tough environments, such as drawing wagons in the American West and carrying supplies up the Nepalese mountains.
Donkey Kicks and Fitness Research

(00:29:06)
  • Key Takeaway: Donkeys can deliver kicks exceeding 2,000 pounds of force, and a 2020 study found that donkey kicks significantly reduced gluteal fat tissue, similar to squats.
  • Summary: The physical defense mechanism of a donkey kick is powerful, reaching speeds over 50 mph. A randomized controlled trial investigated the effects of donkey kick exercises on gluteal adiposity and muscle strength in young women. Both squats and donkey kicks significantly increased muscle gain and reduced localized fat tissue in the buttocks.
Mini Donkeys and Hoof Structure

(00:33:53)
  • Key Takeaway: Miniature donkeys likely originated in Sicily and Sardinia for use on small tracks, and their upright, compact hooves are adapted for dry, mountainous terrain.
  • Summary: Mini donkeys can suffer dental or birthing issues if bred too small without care, but they are popular pets. Donkey hooves are naturally tough and rarely require shoeing, unlike horses, because their structure is designed for dry, rocky environments. In wet climates, donkey feet act like sponges, soaking up water and leading to infections unless they have access to dry standing areas daily.
Donkey Milk and Cleopatra Gossip

(00:57:39)
  • Key Takeaway: Donkey milk has a biochemical profile similar to human milk, historically used for feeding infants and bathing due to its lactic acid content for skin exfoliation.
  • Summary: Cleopatra (or possibly Nero’s wife Poppea) was famously said to bathe in donkey milk for skin benefits derived from lactic acid. Donkey milk production is low-yield, making it expensive, and welfare concerns exist in commercial operations where foals are separated from their mothers. The soft covering on newborn donkey foals’ feet, called ‘fairy feet,’ protects the mother during birth.
Donkey Load Carrying Capacity

(01:07:00)
  • Key Takeaway: Mules are stronger than horses, safely carrying up to 30% of their body weight, while donkeys can carry up to 50% or more under specific conditions.
  • Summary: Donkeys are perfectly adapted for dangerous environments due to their short-footedness, which is why mules are often used in places like the Grand Canyon. Research suggests larger donkeys can carry about 28% of their body weight, though some Indian studies indicate up to 50%. Donkeys loaded over 50% body weight show signs of back issues when lying down, unlike horses (15-25%) and mules (up to 30%).
Ethics of Donkey Rides

(01:09:00)
  • Key Takeaway: Humane work for pack donkeys requires assessing operator kindness, checking for animal sores, and ensuring the work mimics natural activity levels (around 20km daily).
  • Summary: When considering donkey or mule tours, listeners should observe the animal’s condition, looking for signs of infection or rubs, and assess the handler’s kindness and interaction style. Natural donkey activity involves traveling about 20 kilometers daily while experiencing novel situations, which domestication often removes. Good work can be neutral or positive if it imitates natural environments, but profit focus often compromises welfare.
Essential Donkey Rescue Care

(01:11:14)
  • Key Takeaway: The most critical aspects of donkey care are mandatory companionship, provision of dry shelter, and feeding low-quality fiber like straw to prevent obesity from rich feeds.
  • Summary: Donkeys must never be kept alone; they require the company of at least one other donkey to thrive. They need a simple shelter to escape rain, cold, and wind, ensuring they have dry ground underfoot. Owners must avoid overfeeding with rich or sweet feeds meant for horses, as donkeys thrive on low-quality fibers like straw.
Financial and Time Commitment

(01:14:11)
  • Key Takeaway: Donkey ownership is a long-term financial commitment requiring yearly vaccines, dentistry, and bi-monthly hoof trimming, with lifespans often reaching the mid-30s.
  • Summary: Donkeys are not cheap pets, requiring consistent financial outlay for yearly vaccines, dentistry, and hoof trimming every eight weeks. Owners must be prepared for a commitment lasting into their mid-20s or 30s. The most rewarding aspect is spending time getting to know the individual donkey’s personality, as subtle behavioral changes often signal health issues.
Hardest and Best Parts of Work

(01:14:47)
  • Key Takeaway: The hardest part of working with donkeys is making the decision to say goodbye at the right time, as they stoically hide suffering, while the best part is quiet moments with the charismatic animals.
  • Summary: The most difficult aspect of the job is witnessing the devastation owners feel when saying goodbye, especially since donkeys are quiet about their suffering, often continuing with severe foot or dental problems. The best part of the job involves stepping away from administrative tasks to spend quiet time with the donkeys, observing their lives turn around, or feeling a gentle donkey blow on one’s hand.
