Q

What should forage proportion of diet be

A
  1. Mainstay of the diet
  2. rule of thumb proportion: Maintenance = 80-100%
  3. Work:
    light = 80-90%
    Moderate = 50-80%
    Intensive = 30-50%
    Late Gestation = 50-60%
    Lactation = 40-60%

Q

Cereals

A
  1. Oats: Palatable, can be fed whole or rolled/bruised
    Easily digested in small intestine
    53% starch, 12% protein, 5% fat, 12% fibre
    Can be heating – rapid release of energy
  2. Barley: Hard kernel – needs to be treated (crushed/bruised). Limited digestion in small intestine
    Can lead to starch overload in hindgut. Good for condition gain
  3. Corn = Lower fibre, but higher in energy than oats
    High starch, less digested in SI = increased risk of starch overload in large intestine
  4. Bran = Outer portion of wheat grains. Fed as a ‘mash’ : laxative effects! High fibre/low protein

Q

Maintenance energy of a horse lighter than 600kg BW and heavier

A

Horses < 600 kg BW:
MJ/d = (1.4 + 0.03 x BW) x 4.18
Mcal/d = 1.4 + (0.03 x BW)

Horses >600 kg BW:
Mcal/d = 1.82 + (0.0383 x BW) – (0.000015 xBW2)

Q

energy for breeding

A
early gestation = M only
Late gestation (9-11 months) = M+ 20%
Early lactation = M+ 50% (to 12)
Late lactation (13-24 weeks = M + 25%
Stallion in breeding = M +25%

Q

What is haylage

A
  1. NAturally fermented grass
  2. cut white still green, dired for short, baled

Q

What are examples of protein supplements

A

May contain toxins so much boil or cook to deactivate

  1. Linseed = low starch and sugar. High protein. High omega 3 content/ high oil content = safe energy source
  2. Soya bean meal cake = biologially valuable, broodmares

    b) high in fibre = especially soluble fibre
    c) Low sugar no starch
    d) palatable, adds bulk
