How do i know what my horse needs l.jpg
How do I know what my horse needs?

  • Requirements differ with:

  • Individual horse

  • Age

  • Size and weight

  • Body condition

  • Health

  • Weather

  • Physiological state

    • Exercise, breeding, growing, etc.



Starting point determine requirements l.jpg
Starting Point: Determine Requirements

  • Horse Age, Weight, Use

  • To determine weight:

    • Length

    • Heartgirth

      1 kg = 2.2 pounds

      1 inch = 2.54 cm

  • Nutrient Requirements of Horses

Weight (kg) = girth2 x length 11,877


Slide5 l.jpg
“NRC”

  • IN METRIC UNITS!

  • Allows user to manipulate diet (forage, concentrate), horse information

     ration evaluation

  • Does NOT include commercial concentrates

  • Most commercial feed manufacturers will give additional info on feeds when called

Forage quality l.jpg
Forage Quality

  • What determines forage quality?

    • PALATABILITY - Will my animals eat this hay?

    • INTAKE – How much will they eat?

    • DIGESTIBILITY – How digestible is this hay?

    • ANIMAL PERFORMANCE – How will my animals perform on this hay?

    • NUTRIENT CONTENT – What is in the hay?


Nutrients for horses l.jpg
Nutrients for Horses

  • ENERGY

    • Carbohydrates

    • Lipids

  • PROTEIN

  • MINERALS

  • VITAMINS

  • WATER


Other things to consider l.jpg
Other things to consider

  • Grass vs. legume

    • Intake

    • Nutrient Content

    • Digestibility

    • Affects of maturity

  • Species differences

    • Timothy vs. Orchardgrass


Nutrient requirements l.jpg
Nutrient Requirements

  • 1 pound = 454 grams

  • ADG = Average Daily Gain (targeted weight gain for growing animals)

  • DE = Digestible Energy

  • Mcal = Megacalorie = 1000 kcal

Avg bale wt. = 70

Cost = $8.00/bale

The Hays…


Assumptions l.jpg
Assumptions

  • Most horses will eat anywhere from 1.5 - 3% of their body weight in Dry Matter per day

    • Maintenance 1.5 – 2%

    • Growth 2 – 3%

      • Decreases with age

    • Reproduction 1.5 – 3%

      • Highest in early lactation

    • Exercising horses 1.5 – 3%

      • Increases with increasing exercise intensity

What defines performance l.jpg
What defines performance?? quality at an intake of 2% BW in DM relative to requirements


Exercise31 l.jpg
Exercise quality at an intake of 2% BW in DM relative to requirements

  • Amount of energy used?

  • Must know in order to determine amount of energy required

  • DURATION

    • Easy to measure…

  • INTENSITY

    • Many factors at play

  • Other factors?


Energy requirements performance defined l.jpg
Energy Requirements - Performance Defined quality at an intake of 2% BW in DM relative to requirements

  • Light Work

    • Heart rate = 80 bpm

    • 1-3 hours per week

    • 40% walk

    • 50% trot

    • 10% canter

  • Examples:

    • Trail riding

    • Beginning of training

    • Occasional show horses


Energy requirements performance defined33 l.jpg
Energy Requirements - Performance Defined quality at an intake of 2% BW in DM relative to requirements

  • Moderate Work

    • Heart rate = 90 bpm

    • 3-5 hours/week

    • 30% walk

    • 55% trot

    • 10% canter

    • 5% low jumping, cutting and other skill work

  • Very Heavy

    • Heart rate = 110-150 bmp

    • Duration varies  1 hr/week speed work to 6-12 hr/week slow work

  • Examples:

    • Racing (QH, TB, STB, Endurance)

The problems with excess protein l.jpg
The problems with excess protein quality at an intake of 2% BW in DM relative to requirements

  • Makes my horse “hot”

    • Truth or fiction?

  • Excess protein  increase water intake  increase in urination  increase in ammonia in stable

  • Protein is EXPEN$IVE!!


Which hay should you choose l.jpg
Which Hay should you choose? quality at an intake of 2% BW in DM relative to requirements

  • Maintenance  ANY

    • No supplements*

  • Growth  Alfalfa or Mix for weanlings, high quality grass or mix for older

    • DE and/or CP supplementation

    • Vitamin/mineral

  • Reproduction  High quality grass or mix for late gestation, mix or alfalfa for lactation

    • DE and/or CP supplementation

    • Vitamin/mineral

  • Exercising horse  High quality grass or mix

    • DE and/or CP supplementation

    • Vitamin/mineral


Choosing the right concentrate l.jpg
Choosing the right concentrate quality at an intake of 2% BW in DM relative to requirements

  • Base it on your hay! FORAGE FIRST

  • Have a great hay?

    • That 10% CP fortified sweetfeed may be all your horse needs!

    • Better yet, maybe just a forage balancer

  • Not so good hay?

    • Higher quality, higher protein feed may be needed in larger amounts!
