*** FEEDING STRAW TO HORSES ***
Following on from yesterday’s post about trying to never leave your horse in a stable without forage, I promised I’d do a post about feeding straw to increase low calorie forage supply.
Leaving horses without forage for prolonged periods of time is not okay, and can (and does) lead to:
- Ulcers
- Stress
- Colic
- Choke (when they finally get food again)
- Behavioural issues/vices
For any horses that need to gain weight, straw is absolutely not suitable, and you need to be feeding more hay. For any good doers, straw can provide an almost calorie free fibre source and help to prevent some of the above.
1. Straw is not suitable for every horse/pony.
2. Speak to your vet before starting to feed straw, to discuss if age/dentition/medical history make him/her a suitable candidate.
3. If your horse has previously suffered from impaction colic, then you will need to introduce straw extremely slowly, and may not be able to feed it.
4. If your horse has poor dentition (of the cheek teeth (molars)) then they may not be able to eat it. Although some straw can be softer and easier to eat than some courser hays.
5. Feed the best quality, softest straw you can find. Oat straw is thought to be the best, followed by wheat and barley, but the main thing is the softness and quality of the straw.
6. Introduce straw VERY SLOWLY to your horse’s forage ration. I normally advise mixing two handfuls into the haynet and monitoring for a week.
7. Monitor droppings on a daily basis whilst introducing and feeding straw, and if they start looking hard/dry or more “nuggety” than their normal droppings, then you’re feeding too much, have introduced it too quickly, or straw isn’t going to work for them. Stop immediately for a few days until droppings back to normal for that horse, and try again.
8. Personally I advise never feeding more than 25% of the forage ration as straw, although one study has shown that 50% straw:hay is safe, and has no increased risk of ulcers.
9. Straw can still be fed if your horse doesn’t like it, as it will slow down the amount of time it takes your horse to eat the hay, due to him picking around the straw.
10. Straw can be steamed to ensure as much dust as possible is removed, and to make it more palatable.
11. If your horse won’t touch his haynet with straw mixed into it, then obviously that is defeating the point of increasing forage, so pop a few handfuls into a separate net and go from there.
12. Always ensure easy access to fresh water (obviously this applies regardless of what you are feeding!).
13. Increase volume of straw fed by just a couple of handfuls every 7-10 days, or even slower if you have any concerns at all about droppings.
14. Ensure a good quality Feed Balancer is always fed, regardless of whether or not you are feeding straw. All of my good doers are on Baileys Lo Cal.
15. If you decide to feed straw, invest in some hanging luggage scales to ensure you don’t feed too much of the forage ration as straw.
16. If you currently need to feed soaked hay, then you will need to continue soaking your hay as you introduce straw, or it will defeat the object.
17. If your horse/pony is finishing all of his forage intake by 11pm/midnight, and standing in his stable with nothing until 7am (or even later) when you arrive, this is absolutely not okay, and you need to do something about it.
18. There are very few studies on feeding straw, so the above is based on a couple of studies and my experience of introducing straw into rations with my clients.
19. Chopped straw/chaff is an alternative (you may be able to leave your horse with a bucket of dampened down chaff overnight) but avoid chaff completely if your horse has been diagnosed with diastema. Again, you need to know about your horse’s dentition before introducing this.
20. Introduce good quality straw extremely slowly, and stop immediately if the droppings look very hard/dry.
