OBJECTIVES:
| DM intake | Maintenance: 0.14 MJ x BW. Racing: double (140MJ) |
|---|---|
| Forage to concentrate ratio, | Light working horses = 65:35 |
| Moderate work horses = 50:50 | |
| Heavy work horses = 35:65 (race horses need almost double of maintenance) | |
| Feed supplements, | Ca/P/Mg for bone; vitamin E & C, |
| salt. | 1% NaCl in concentrates due to sweating |
★ Goal ⇒ minimize excess weight whilst not sacrificing energy stores or their availability
Inadequate energy intakes, even of a short duration, potentially will result in a more rapid onset of fatigue and reduced performance
For most athletic horses, BCS between 4 (racehorses) and 6 (dressage)
DM : 1,5 - 3% of BW
DE: 1.9x DE of maintenance for race horses , 1.6 x DE maintenance for dressage
CP: 12-16%
FAT: 8-10%
Elevated amounts will increase muscle glycogen stores → glycogen-sparing effect to increase energy density of ration.
The nutrient requirements of breeding stallions are assumed to be similar to those of other adult horses, with allowances for level of activity.
Very much depends on type of stallion → breeding season or not, length of it etc…
Level of activity = the sum of breeding frequency and physical activity
Stallion req:
| Non-breeding | Breeding | Intensive-breeding | |
|---|---|---|---|
| DE | 0.14 MJ x BW. | more | even more |
| CP | 16% | much more | more |
| Forage | 10-12 kg | 10-12 kg | 10-12 kg |
| Concentrate | 0 | 2-3kg | 3-4kg |
| Vit-E | high | higher | highest |
| BCS | 5-6 | ||
| Hay req | good quality is enough | Good quality |
+
concentrates | Good quality + concentrates |
