A7. Maintenance Requirements of Horse, Feeding Practice

Question 1

DM intake

Energy requirement

Answer 1

1.5- 3% of BW (approx. 2kg/bwkg) (500kg horse–> 10kg)
DE (MJ) + then we compare with BCS! Look at individual!

Maintance; 0.14M * BW kg

Maintance* activity
M* pleasure (1.2)
M* racing (1.9)

Question 2

Ca, and P requirements

Ca:P ratio

Answer 2

Calcium = 20g
P = 14g
Ca: P ratio = 1,5 -2:1 !
Phosohorus can make more damage, easly absorbed, more calcium

Question 3

Tap water

Answer 3

• 5l /100 Kg (normal)
  Depends on the;
• work, temperature, status, diasese

Question 4

BCS

Answer 4

4 Moderately thin
5 Moderate
6 Moderately Fleshy

Question 5

Daily DM and feed intake

Answer 5

Energy Requirement; for a 500kg horse
Energy  (DM) needed = 67-70MJ (maintenance) 
Crude Protein (g) needed = 670-700

Question 6

Forage to concentrate ratio.

Minimal daily hay requirement

Answer 6

65/35 most tolerate

10-10,5 kg for a 500kg horse
