Title: Domestication and Breeding of Animals


1
Domestication and Breeding of Animals
The same processes worked for animals like...
2
Domesticated and Bred Pigeons
All Breeds came from a single original species
3
Domestication of an animal is defined as an
animal selectively bred in captivity and thereby
modified from its wild ancestor, for use by
humans who control the animals breeding and food
supply.
4
What traits were humans looking for in animals?
Source of food, milk products, fertilizer, land
transport, leather, military assault vehicles,
plow traction, and wool. The big mammals
provide most of these traits.
5
The 5 major mammals domesticated were
Sheep From Asiatic Mouflon sheep
6
The Goat from the Bezoar goat
7
The Cow from the now extinct Auroch
8
The Pig from the wild boar
9
The Horse from the now extinct wild horses of
Russia,. Related to the Przewalskis horse
10
What do you think are the other main animals
domesticated by man?
  • Arabian Camel
  • Bactrian Camel
  • Llama and Alpaca
  • Donkey
  • Reindeer
  • Water Buffalo
  • Yak
  • Bali Cattle

11
Why was eurasian horses domesticated and not
African Zebras?
  • Diet
  • Herbivores are more efficient in terms of energy
    conservation
  • It takes less energy to farm a herbivore than a
    carnivore

12
Breeding problems
  • Some animals will not have sex in captivity
  • For example Cheetahs have a courtship in which
    the female is chased by the male for three
    days.This is not possible in captivity
  • Cheetahs have never been domesticated

13
Nasty Disposition
  • Some animals are just plain nasty
  • The Grizzly bear, African Buffalo, and Zebra to
    name a few

14
Tendency to Panic
  • Some animals are nervous and programmed for fast
    flight if they sense danger
  • E.g. Deer and antelope
  • Some animals are slower, less nervous and will
    seek protection in herds if attacked.
  • E.g. Sheep and goats

15
Social Structure (part 1)
  • Some animals live in herds, have a dominance
    hierarchy established, and have overlapping home
    ranges
  • This allows the human to take over the role of
    dominance. The animals imprint on humans

16
Social Structure (part 2)
  • Solitary, territorial animals that dont like
    herds wont imprint on humans.
  • E.g. Cats
  • Some animals are territorial during breeding
    seasons, when they fight and dont tolerate each
    other
  • E.g. Deer

17
Social Structure (part 3)
  • Some animals lack a well defined dominance
    hierarchy
  • E.g Bighorn sheep

18
Growth Rate
  • For an animal to be of benefit to humans it needs
    to grow fast.
  • E.g. Cows, sheep
  • Animals like elephants grow to slowly to be of
    use.
