4. Uses of Horses

5. Uses of Horse

6. Sources of Horses  Purchase from Breeders—best source Private owners Auctions Dealers

7. Age of Horse to Buy  5-12 years is the prime of life Horse in this age range are best for young or inexperienced riders  Young horses require more training and may not be safe for young or inexperienced riders.  Age can be determined by looking at the front teeth  See fig. 31-34

8. Sex of Horse to Buy  Studs Hard to manage and control  For pleasure riding geldings and mares are the best choice.

9. Breed Selection  Intended use  Some breeds are better adapted to certain uses.  Personal preference  People not interested in breeding or showing may choose a good grade horse. They make excellent mounts for trail and pleasure riding and even ranch work.

11. Conformation

12. Feet and Legs  Two of the most important parts  Leg conformation influences how the horse moves Correct Position

13. Feet and Legs  See fig 31-26, 27, 28, 29, 30 for the correct and incorrect positions of the front and rear legs.

14. Feet  The horse carries it’s weight on the wall, bars, and frog. The sole normally does not touch the ground  The hoof should be kept properly trimmed to keep the horse standing squarely and moving straight  The hoof grows at a rate 3/8” to 1/2” per month  Feet should be trimmed every month to 6 weeks

15. Feet  Should be kept moist to prevent cracking  To keep feet from drying out use a hoof dressing or allow the horse to stand in a moist area  The pastern and hoof should form a 45 deg. angle with the ground  See fig. 31-31

17. Body Color (start)  5 basic colors Bay, black, brown, chestnut, white  5 major variations Dun, gray, palomino, pinto, roan  Piebald- white and black color combination  Skewbald- white and any other color  Roans Blue roan- mixture of black and white hairs Red roan- mixture of bay with white hair Strawberry roan- mixture of chestnut with white hair

22. Leg Markings Socks: Stocking, sock (boot), sock (fetlock) L-R: Pastern, Coronet, Partial Pastern

23. Unsoundness's & Blemishes  Unsoundness- a defect that affects the usefulness of the horse  Blemish- an imperfection that does not affect the usefulness.  Most serious unsoundness's affect the feet and legs  See p. 583-585

24. Vices  Develop due to idleness or poor handling

25. Cribbing  Horse bites down on some part of the feed manger or stall  Wind sucking occurs when the horse presses the upper front teeth on some object and pulls back, at the same time sucking air into the stomach.  The two often occur together  Looked down upon by buyers.

26. Other Vices  Halter Pulling Horse pulls back against the halter while tied  Kicking

27. Gait  The movement of the horse’s feet and legs when the horse is in motion  3 natural gaits Walk, trot, gallop  Other gaits Canter, stepping pace, running walk, fox trot, amble, rack, pace

29. Walk  Slow  4 beat  Each foot leaves and strikes the ground separately from the other feet.

30. Trot  Fast  Two beat diagonal  Opposite front and hind feet leave and strike the ground at the same time.

31. Gallop  Fast  Four beat  Feet strike the ground separately in this order (1) one hind foot (2) the other hind foot (3) the diagonal front foot (4) the other front foot  For a brief moment all 4 feet are off the ground.  The extended gallop is the run.  http://en.wikipedia.org/wiki/Horse_gaits#W alk http://en.wikipedia.org/wiki/Horse_gaits#W alk

32. Canter  Slow  3 beat  Feet strike the ground (1) one hind foot (2) the other hind foot and diagonal front foot (3) the other front foot  Western adaption is a very slow canter called the lope

33. Stepping Pace  Slow  Lateral  Four beat  Four feet strike the ground separately (1) right hind foot (2) right front foot (3) left hind foot (4) left front foot

34. Running Walk  Slow  Diagonal  4 beat  Each foot leaves and strikes the ground just ahead of the diagonal hind foot  Natural gait for the Tennessee Walking Horse

36. Rack  Fast  Even  4 beat  The time between each foot striking the ground in the same  The order of the feet striking the ground is the same as the stepping pace.

37. Pace  Fast  2 beat  Front and hind feet on the same side leave and strike the ground at the same time.  There is a brief moment when all four feet are off the ground at the same time

38. Amble  Lateral movement  Also called the traverse, side step, or side pass  Not a show gait  The horse moves to one side with out going forwards or backwards

39. Pedigree  Of great importance when selecting show and race horses  Ancestors back of the grandparents contribute little to the genetic inheritance  See Example Pedigrees

40. Price  Will vary  Grade horses are typically lower priced than registered horses  Registered horses with the potential for showing are higher priced  Currently the price of horses is very soft due to the closing of all the kill plants in the United States

41. Summary  75% of horses are used for personal pleasure riding  Other uses include: racing, ranching, breeding, commercial ridding  More than 5 million horses in the United States  More than $16 billion dollars spent in the horse industry annually

42. Summary  Many breeds of light horses  Horses should be selected on the basis of conformation, use, age, sex and soundness. Breed selection is a matter of personal preference  Breeders are the best source of horses, other sources include private horse owners  The five basic colors-bay, black, brown, chestnut, white Variations- dun, gray, palomino, pinto, roan  Variety of unsoundness's and blemishes  Unsoundness is more serious and the most serious affect the feet and legs  Gait of the horse is the way it moves
