DEALING WITH HAY SHORTAGES

STRETCHING HAY SUPPLIES

hay supplementation considerations
Hay Supplementation Considerations
  • Horse = NON RUMINANT HERBIVORE

1. Gastrointestinal function

2. Behavior

hay supplementation considerations3
Hay supplementation considerations
  • How much hay is needed?

1. Minimum of 0.75 to 1% in dry matter or hay as fed? Not less than 50% of total diet?

2. Minimum of 24% NDF (13% Crude fiber) or 14% ADF?

3. Does form of hay make a difference?

chopped, cubed, pelleted

relationship of ndf crude fiber
Relationship of NDF & Crude Fiber
  • Legume hays

NDF = (Crude fiber % - 2.07)/ 0.546

  • Grass hays

NDF = (Crude fiber % - 3.72)/ 0.4

know how much hay you are feeding
Know how much hay you are feeding
  • Weigh hay to make sure it is not less than 0.75% of body weight.
  • Limit time on round bales, i.e. will generally be full 1 to 2 hours AM & PM.
  • Commercial feeds higher than 14% crude fiber, hay can make up 0.5% BW.
hay roughage substitutes
Hay – Roughage Substitutes
  • Beet pulp
  • Alfalfa cubes & pellets
  • Soy hulls
  • Haylage
  • Cottonseed hulls
  • Citrus pulp?
  • Complete feeds

** Whatever is substituted make sure chew factor is present.

beet pulp
Beet pulp
  • DE approximately 1.0 Mcal/lb, Crude protein 8-10%, NDF 40.5%
  • Substitute up to 50% of hay.
alfalfa cubes pellets
Alfalfa Cubes & Pellets
  • Remember you are feeding alfalfa.
  • Cubes and pellets are consumed rapidly, chew factor and stem length of concern.
  • Choke concern with pellets.
  • Cubes up to 50% for long stem hay.
  • Pellets up to 25% for long stem hay.
soy hulls
Soy hulls
  • NDF 61%, C.P.11-13 %, DE 0.8 -1.1 Mcal/lb.
  • Booth, et al. replace up to 50% of forage in diet.
  • Recommendation probably no more than 25% as sorting will occur, chew factor concern as no long term studies have been reported.
cottonseed hulls
Cottonseed hulls
  • DE .50 Mcal/lb, C. protein 3.8%, NDF 80%.
  • Maximum of 20% of total diet.
  • Mix with grain or can mix with chopped hay.
haylage
Haylage
  • High moisture ensiled hay harvested at 40 – 60% dry matter.
  • Highly acceptable, actually prefer over hay.
  • Slightly more digestible than hay?
  • Disadvantage with wet (high moisture), possibility of spoilage if not fed relatively quickly.
  • Botulism rare but possibility.
