Friday focus….feeding forage to current body weight!
For those of you monitoring your horses bodyweight or trying to get them to lose weight, please, please feed them to their current bodyweight, not their ‘ideal’ bodyweight. Feeding to their ‘ideal’ weight can significantly under feed forage, which can have a huge effect on both digestive and behavioural health.
I absolutely despair with the forage side of the equines rations sometimes and I get so disheartened hearing time and time again about other equine health professionals and ‘experienced’ horse people recommending forage amounts that are far too low. We know that feeding below 1.5% (dry matter) of bodyweight negatively affects digestive and behavioural health, so why do it and risk compromising either?!
Weight loss should be carried out gradually and forage rations should be adjusted as they are losing weight, to ensure they continue losing weight. Regular weight checks are required for this, ideally on a weighbridge for accuracy.
If we take the weighbridge weight of 714kgs in the picture below as an example. Say someone says that this horse needs to lose 100kgs; if this horse is fed to what is presumed as their ‘ideal’ bodyweight of 614kgs they would be getting 9.2kgs (dry matter) of forage in a 24-hour period. At their current bodyweight, fed at 1.5%, this horse needs 10.7kgs (dry matter) of forage in a 24-hour period, quite a difference!
The dry matter of the forage is also very important and something that is frequently missed from calculations!
If this horse is fed a hay only diet 24/7, and the dry matter of the hay is 88% (it is usually around 85-89%), then fed at current bodyweight the 10.7kgs becomes 12.2kgs and at ‘ideal’ bodyweight, the 9.2kgs becomes 10.5kgs. Again, huge differences!
So if our 714kgs horse is fed at the ‘ideal’ bodyweight of 614kgs and the dry matter of the hay is not taken into account, then they will be getting 3kgs of hay less than they should be, which will make a huge difference to them.
If you are not sure what the correct rations for your horse or pony are, please get a nutritionist to help you. Your horse or pony can lose weight with the right help whilst minimising the risk of digestive or behavioural upset.
I urge you not to go with flippant figures ‘plucked’ out of the air from any equine health professionals for your horse or ponies sake. I would never compromise my own horses in this way, ever. Forage is a basic requirement and one that we should not be getting wrong, particularly when we know what the consequences of underfeeding it are!
