    Research slow to prove effectiveness
    Expectations fueled by testimonials and ads
  • 22. Abnormal Joints
    Training hard on joints
    • Acute vs. Chronic
    Caused by:
    • Mechanical Stress (injury, poor conformation)
    • 24. Chemical Stress (bacterial)
    Result = Osteoarthritis
  • 25. Chondroitin Sulfate
    Is part of the natural body lubricants called glycosaminoglycans (GAGs)
    Elements of connective tissue and cartilage
    • Help with cartilage damage
    • 26. Replace proteoglycan
    • 27. Anti-inflammatory effect
    • 28. Inhibit enzyme destruction
    Absorption by gut – 32%
    • Large molecule
    • 29. Broken down and reassembled?
  • Glucosamine
    Makes up ½ of the hyaluronic acid and chondroitin sulfate molecules
    Helps form proteoglycans that lubricate and protect cartilage
    • Precursor to GAG
    • 30. Is the “rate-limiting” step in production of GAGs
    • 31. Anti-inflammatory effect
    Absorption documents – 2.5%

    Trace mineral
    Required as co-factor for synthesisof GAG
    Added to make sure enough Mnavailable for synthesis
    Nutrient requirement vs. intake
    • Little danger
  • Manganese
    Supplemented as Ascorbate orAscorbic acid
    Co-factor for formation of collagen
    Horses produce their ownVitamin C
    More = better?

    Poor pasture may have low vitamin levels
    (Greiwe-Crandell et al., 1995)
  • 45. Vitamin E & C
    Vitamin C may spare vitamin E by reducing radicals and restoring vitamin E activity
    Polo ponies at high exercise intensities benefited from Vitamins E + C supplementation
  • 46. Vitamin E & Se
    Se is a cofactor for GPx, an antioxidant enzyme
    • Most commercial feeds have additional Se
    • 47. Soil content varies throughout the country
    • 48. Can be toxic!
    • 49. Blind staggers = weight loss, anorexia, excessive salivation, jaundice or necrosis of heart and liver
    Required = 0.3 mg/kg diet (about 3 mg/day)
    • Toxic = about 18 mg/day
    Se + E can potentate the antioxidant effects
  • 50. Water & Electrolytes
    Exercise:  heat production
    Dissipated in sweat and respiratory tract
     losses of electrolytes
    Dehydration results in  performance
    • Accompanied by coldness, fatigue, muscular tremors, colic, thumps, appetite
  • Electrolytes
    Carry an electrical charge
    Endurance horses can lose upto 6-8% of their BW as water
    Largest portion of horse sweat is Na, Cl, K
    • These increase 3-, 7-, 6-fold
    • 51. Small amounts of Ca and P
    Na, K, Mg, Ca, Cl
  • 52. Electrolytes
    Not all electrolytes are created equal
    Look for % sugar or ingredient listing
    1st ingredient should be salt (sodiumchloride)
    If it doesn’t taste like salt it will not do much for your horse
  • 54. Electrolytes for Competition
    • 1-2 oz. at every vet check
    Dose supplementation
  • Hoof Supplements
    Experiments with positive results on:
    • Biotin – therapeutic quantities
    • 59. Zinc
    May help poor feet
    • Dependant on problem
    Won’t help good feet
    Good balanced diet may be moreeffective than hoof supplement
  • 60. Major Nutrients for Hooves
    • B Vitamin activates production of keratin
    • Essential for thyroid hormones that develop all tissues
    • Responsible for keratin within the hoof
    • Contributes to the health of the hoof & reactions controlling metabolism
  • Recommended Dosages
    Biotin: 20 mg/day

    • Water soluble they will not be toxic at these supplemented levels

    • Make sure you are not overdoing the Mg
    • 65. If you are on another mineral supplement I would stop feeding it with the calming aid

    Herbal supplements are NOT always safe
    Joint supplements are NOT the magic drug
