  1. Classification of Agricultural Animals

  2. Organisms • Identified, grouped, and classified • More effectively study and communicate about them • Plants and animals are classified or grouped together by characteristics they have in common

  3. They may be characterized by • The uses people make of them • Physical characteristics • Other categories used to put similar animals together

  4. Classification • Several ways of classifying agricultural animals • Agricultural animals have been domesticated for some type of human use • These animals have been developed into breeds having distinctive characteristics and distinctive uses

  5. Scientific Classification • Binomial nomenclature: Giving two names in Latin • System developed by Swedish Botonist named Linnaeus

  6. Binomial Nomenclature • Genus: First name, always capitalized • Species: Second name, always lowercase • Both are underlined!

  7. Latin • Was used because at the time, it was the international language of scholars • Many languages of the world were based on Latin.

  8. Example • Cattle: Bos taurus • Pigs: Sus scrofa • Horses: Equus caballus • Sheep: Ovis aries • Dogs: Canis familiaris

  9. Common Names • Are often confusing • Different organisms can have similar or the same common name • Different parts of the country may have different common names for the same animal.

  10. Scientific Classification • Orderly and systematic approach to identification • Broad groups of animals are classified together in categories of common characteristics

  11. Scientific Classification • Each group is then broken down further into smaller categories • Process is repeated until the groups cannot be categorized into smaller groups.

  12. Seven Levels of Classification • Kingdom- largest • Phyla • Class • Order • Family

  13. Seven Levels of Classification • Genus • Species- smallest

  14. Kingdoms • Animalia: all multicelled animals • Plantae: multicellular plants that produce chlorophyll through photosynthesis

  15. Kingdoms • Monera: bacteria and blue-green algae • Protista: paramecia and amoebae • Fungi: mushrooms and other fungi

  16. Kingdom • The Kingdom animalia includes all animals ranging from a tiny gnat to huge whales. Because of this diversity we have to further subdivide into phyla.

  17. Phyla • The primary divisions of the kingdom Animalia • The kingdom animalia is divided into twenty-seven phyla.

  18. Phyla • The word phyla comes from the Greek word phulon meaning race or kind • Several phyla are divided into subphyla • Most agricultural animals belong to the phylum Chordata

  19. Phyla • Chordata is divided into subphylas • Vertebrata – animals with backbones

  20. Classes • The phyla and subphyla are further divided into classes. • Agricultural animals such as horses, cattle, goats, sheep, and pigs belong to the class Mammalia.

  21. Classes • Amphibia: frogs, toads • Reptilia: turtles, snakes, lizards • Aves: birds • Mammalia: horses, cattle, pigs

  22. Orders • Classes are divided into smaller groups that categorize animals within a class that possess certain characteristics called orders.

  23. Order • The class Mammalia contains eighteen different orders including • Primates – humans • Artiodactyla – cows, goats, sheep, pigs

  24. Artiodactyla • The order Artiodactyla have three suborders. • Suiformes: pigs, hippopotami

  25. Artiodactyla • Tylopoda: camels, llamas • Ruminantia: deer, cattle, sheep

  26. Families • Orders and suborders still have to be broken down smaller. These are called families.

  27. Genus and Species • The final categories of the scientific classification system are genus and species.

  28. Genus and Species • The Genus and Species are also an animal’s scientific name. • These are always Latin or latinized

  29. Classification of Breeds • A breed of animals is defined as a group of animals with a common ancestry and common characteristics that breed true.

  30. Classification of Breeds • Breeding true: means that the offspring will almost always look like the parents

  31. Selective Breeding • Choosing the best and desired animals and using those animals for breeding purposes.

  32. Purebreds • These are animals whose ancestors are of only one breed.

  33. Breed Associations • An organization that promotes a certain breed of animal. They control the registration process of purebred animals of that breed.

  34. Blood Typing • Not only physical characteristics are used in breed identification. • Blood typing is analyzing and animals blood to determine their history.

  35. Crossbreeding • Sometimes species can be successfully crossed to produce new breeds.

  36. Example • One of the first successful breeds: Santa Gertrudis, which a cross between Shorthorn breed of cattle with the Brahman breed of cattle.

  37. Classification According to Use • Meat Animals • Work Animals

  38. Classification of Horses • Cutting horses: used to heard and work cattle • Draft Breeds: used to pull wagons and heavy loads

  39. Classification of Horses • Harness Horses: used for pulling sulkies or light carriages

  40. Dual-Purpose Animals • An animal that is raised for more than one purpose.

  41. Examples • Cows and Calves • Sheep • Camels (in the desert of the Middle East)
