SDZG Husbandry

Sources: Brynes (2015) and Carmignani (2016), except where noted

Diet in managed care

  • Adults
    • Meat-based diet
    • Adult females (Tony Franceschiello, personal communication, 2016)
      • Eat about 5-6 lbs of food per day
    • Adult males
      • Eat about 10 lbs of food per day
  • Cubs

Healthcare and training

  • Each lion is checked over each day to monitor its health and note any concerns
    • Lions present various parts of their bodies (e.g., paws, mouth) for keepers to examine
  • Husbandry behaviors
    • “A way for keepers to communicate with the animals they care for” (Byrnes 2015)
    • Used to provide care, weigh animals, perform health checks, and move/transport animals
    • Keepers use a combination of operant conditioning, positive reinforcement, and trust-based relationships
    • When providing care, there is a safe barrier between keeper and the lion (“protected care”)
    • Example husbandry behaviors
      • Present paw
        • Check claws and toes
      • Open mouth
        • Check teeth and gums
      • Rise up
      • Lie down
      • Go to station/target
      • Crate
        • Used for transport
  • Specialized health check tasks
    • Give vaccinations (e.g., rabies and feline viruses)
    • Take blood samples
      • Monitor response to vaccinations
      • Check for infections or organ problems
      • Test for heartworm
    • Administer eye drops following cataract surgery (Tony Franceschiello, personal communication, 2016) 

Enrichment

  • Helps keep lions active and challenged
  • Types provided by keepers
    • Social play
      • Interact with pride members
    • Exhibit elements
      • Trees to climb
      • Rises and structures to sleep on
      • Glass panels allow interation with guests
    • “Meatball hunts”
      • Meat treats hidden throughout the exhibit
      • Keep lions’ hunting skills honed
    • Novel objects to explore and play with
    • Scents
      • Kitchen herbs, animal hair, high-end perfume, wood shavings, elephant dung
      • Rub and roll on these smells
        • Wild lions mask their scent to improve their hunting success
    • “Blood-sicles”
      • Bits of meat in frozen ice blocks
        • Special treat on hot days
      • Stimulates senses of smell, touch, and taste

A Special Enclosure for a Special Lion

Prince a lion

Prince, the San Diego Zoo's most famous lion, investigates a new zoo habitat.

In 1923, Prince and two female lions, Julia and Sarah, became a sensation in the San Diego Zoo's new open-air lion grotto. The first of its kind outside of Europe, this enclosure with no bars was dubbed revolutionary.
