1 Domestication of Farm Animals For: ADVS 1110 Introduction to Animal Science

2 Domestication: Terminology Wild Animal: An animal not genetically altered by artificial selection for use by humans. Tame Wild Animal: A wild animal that, through intervention of man, has adapted behaviorally so as to be traceable and useful to humans.

3 Domestication: Terminology Exotic Animal: A wild animal belonging to a species whose historic native range lies totally outside Canada and the United States and/or its territories. Domestic Animal: An animal that has been genetically altered from the original wild species for use by humans through the agency of artificial selection.

4 Domestication: Terminology Feral Animal: A domestic animal that lives in the wild with no human assistance. Feral Population: A reproducing group of feral animals.

5 Domestication: Terminology Breed: A population of domestic animals, the individuals of which may vary within defined phenotypic and genotypic limits. When mated among themselves, the offspring produced are also within the original limits. Breeds generally have an organization or association of breeders, who generally breed their animals according to a stated conceptual standard.

6 Domestication: Terminology Variety: A variety is used in some species to designate groups of animals within a breed that have shared morphological (structural) traits, such as coat types, comb types, patterns, and the presence or absences of horns. A common term utilized with chickens and turkeys.

7 Domestication: Terminology Strain: A sub-population of a breed or a variety that has unique ancestral similarities or a restricted phenotypic range as compared to the breed variety as a whole. Landrace: A population of domesticated animals locally selected and used and generally bred within itself. A landrace tends to vary within itself somewhat more than does a breed and tends to not have organized breeders or a breed standard.

8 Domestication Domestication by D. Webster: To adapt an animal or plant to life in an intimate association with and to the advantage of man or another species, by modifying growth and traits through provision of food, protection from enemies, and selective (artificial selection) breeding during generations of living in association and often to the extent that the domesticated forms loses the ability to survive in nature.

9 Domestication Domestication by R. Bennett, Man and Earth s Ecosystems : A domesticated plant or animal is one that people have consciously taken into the cultural context of their living space for any purpose whatsoever.

10 A Domesticated Animal: The animal is valued and there are clear purposes for which it is kept. The animal s breeding is subject to human control. The animal s survival depends, whether voluntary or not, upon humans. The animal s behavior (psychology) is changed in domestication. Morphological characteristics have appeared in the individuals of the domestic species which occur rarely if at all in the wild.

11 The Process of Domestication WILD TAME? FERAL DOMESTIC BREED

12 The Process of Domestication Voluntary Symbiotic Association Based on Guest-Host Relationship: Exploitation by the Guest (Species) Scavenging Exploitation by the Host (Man) Feeding Robbing Taming Parasitism Domestication

13 The Process of Artificial Selection Domesticated Animal Breed Variety Strain Landrace

14 Chronological Development of Common Domestic Animal Species

15 Specie: Dog When: 12,000-14,000 B.P. (Before Present) Where: Old & New World Why: Pet, Companion From: Wolf or Jackal

16 Specie: Sheep When: 9,000-10,700 B.P. Where: Old World Why: Food, Milk & Clothing From: European Mufflon & Asiatic Urial

17 Specie: Goat When: 8,500-9,000 B.P. Where: Old World Why: Food, Milk & Clothing From: Wild Goat

18 Specie: Cattle When: 6,000-6,500 B.P. Where: Old World Why: Religious Reasons From: Auroch

19 Specie: Pig When: 8,000-9,000 B.P. Where: Old World Why: Food & Sport From: European Wild Boar

20 Specie: Horse When: 4,000-5,000 B.P. Where: Old World Why: Transport & Warfare From: Wild Horse

21 Specie: Chicken When: 5,000-5,500 B.P. Where: India, Sumatra & Java Why: Cockfights, Show, Food, Religion From: Jungle Fowl

22 Animal Domestication: Summary Without the domestication of wild animals by humans, the human race most likely wouldn t have survived. Today s sustainable availability of animal products and their provision of food, clothing, and shelter in some cultures is essential for the future of humankind. Responsible breeding and husbandry are mandatory if the global growth is to survive.

23 This is what makes our domestic animals valuable.
