Equine husbandry Flashcards
Horse average DM intake
3% body weight
Dentition
Prehension = incisors Mastication = molars
What should forage proportion of diet be
- Mainstay of the diet
- rule of thumb proportion: Maintenance = 80-100%
- Work:
light = 80-90%
Moderate = 50-80%
Intensive = 30-50%
Late Gestation = 50-60%
Lactation = 40-60%
What proportion of fresh forage (grass)
10-30% DM
What proportion of conserved forage
- must be older than 2 months before feeding
- hay = 80-90% DM
- Haylage = 50-65% DM
Cereals
- 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 - 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 - Corn = Lower fibre, but higher in energy than oats
High starch, less digested in SI = increased risk of starch overload in large intestine - Bran = Outer portion of wheat grains. Fed as a ‘mash’ : laxative effects! High fibre/low protein
Maintenance energy of a horse lighter than 600kg BW and heavier
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)
energy for breeding
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%
What sort of GI are they described as having?
monogastric, hindgut fermenters
What plants are toxic to horses
- Ragwort
2. Acorns/ Sycamore
What is hay?
- coserved grass/alfalfa
2. cut while still green then dried (protein content dec with age, fibre and lignified tissue inc
What is haylage
- NAturally fermented grass
- cut white still green, dired for short, baled
- Highly nutritious, digestible and palatable
- Reduced dust, spoils quickly once opened
What are examples of protein supplements
May contain toxins so much boil or cook to deactivate
- Linseed = low starch and sugar. High protein. High omega 3 content/ high oil content = safe energy source
- Soya bean meal cake = biologially valuable, broodmares
What is an additional fibre source for horses?
- sugar beet:
a) requires soaking
b) high in fibre = especially soluble fibre
c) Low sugar no starch
d) palatable, adds bulk
e) calcium rich
How can feed be presented?
- Haynets/bags
- racks
- mangers
- floor
