Promotional Characteristic with Dengie
Understanding of equine gastric ulcer syndrome (EGUS) has advanced over the previous 30 years to the purpose that it’s now identified any horse may have ulcers and it isn’t a illness confined to the traditional underweight horse in poor situation.
In actual fact, one research has proven that solely half the horses visiting a Belgian equine hospital for ulcer therapy had been underweight. There additionally seems to be no hyperlink between the severity of ulcers and the indicators – some horses are clearly very stoic and may have grade 4 ulcers with no apparent scientific indicators in any respect.
Because of this, and since it typically makes good sense to take action, recommendation for feeding all horses in the present day is to maintain ranges of starch low and use excessive fibre diets as a lot as doable.
However what does this imply in apply? Dengie solutions some FAQs on feeding horses to scale back the chance of ulcers.
1. How low is a low starch weight loss plan?
The extent of starch typically really helpful is 2g/kg body weight (BW) per day or 1g/kg BW per meal as a research confirmed that feeding above these ranges greater than doubled the chance of a horse having ulcers.
Cereal-based mixes and cubes can fluctuate significantly within the quantity of starch they supply and vary from round 10% to as excessive as 30%. A producer of a feed containing 10% starch may subsequently declare that their feed is low starch when it’s in comparison with different cereal-based feeds.
The desk under exhibits the distinction in starch ranges between Alfa-A Oil and a cereal-based feed with the identical degree of vitality per kg. Dengie Alfa-A Oil can rightly declare to be a lot decrease in starch than even the “low” starch cereal combine – 5 occasions decrease!
The opposite issue to think about is the quantity being fed. The desk under exhibits how feeds with the identical starch content material, however completely different feeding charges, can even present very completely different ranges of starch within the ration.
This implies you will need to think about each the extent of starch and the quantity fed.

2. How a lot forage ought to I feed my good-doer with ulcers?
The growing frequency with which ulcers is being identified might account for why the suggestions for minimal dry matter consumption have a tendency to extend in newer research. The consensus amongst most vets and nutritionists for the long run administration of good-doers is 1.5% of present body weight on a dry matter foundation.
Dengie breaks this down a bit of bit extra:
- 1.5% – earlier research have gone as little as 1% of body weight and whereas no hostile results on welfare of the horses had been discovered, the research didn’t search for ulcers and lasted 12 weeks.
- Present body weight – we advocate utilizing the horse’s present body weight as it’s much less subjective than attempting to estimate what the horse’s preferrred body weight ought to be. If the load loss programme works, then the consumption required will steadily cut back according to the horse’s weight reduction. A gradual discount in consumption is a a lot safer strategy to sustaining digestive well being than one huge drop.
- On a dry matter foundation – wetter forages resembling haylage might solely include 60% dry matter, whereas hay is round 85% dry matter. If suggestions are given on an as-fed foundation, a horse receiving haylage will likely be consuming a lot much less fibre than the horse on hay, as 40% of what’s consumed is water. If attempting to calculate how a lot forage your horse can have on a dry matter foundation is complicated please don’t be embarrassed to ask for assist – our nutritionists will do that for you so you realize you’re utilizing the correct quantity.
- Long run administration – to take care of an acute vital weight problems or laminitis scenario it could be obligatory to scale back to under 1.5% for 3 to 6 months for instance. The purpose would all the time be to return to not less than 1.5% as quickly as doable to scale back the chance of different well being points resembling ulcers.
The important thing take-home message right here is: use a decrease vitality forage or low-calorie forage replacer resembling Dengie Hello-Fi Lite or Dengie Ulser Lite, in order that extra may be fed with out selling weight achieve, relatively than decreasing to under 1.5%
3. Can I feed straw to a horse with ulcers?
One method to handle forages which can be larger in vitality or sugar is to combine them with straw. Sadly, misinformation about straw places some individuals off utilizing it, particularly for these with ulcers.
In 2009, a research that appeared on the incidence of gastric ulceration in a inhabitants of horses discovered that those who had been fed straw as the only or predominant fibre supply had been extra prone to have ulcers. Nonetheless, the important thing right here is that straw was used as the only or predominant fibre supply, which isn’t usually accomplished within the UK.
Recognising that straw may be helpful as a low-calorie forage supply for good doers, a follow-up research has been revealed investigating the security of feeding 50% wheat straw to switch haylage. The research discovered no ailing results and particularly appeared for gastric ulcers indicating straw could possibly be a very helpful ingredient within the struggle in opposition to ulcers and weight achieve!
Following this research, Dengie has accomplished some easy calculations that present that if straw is used to switch one third of the load of a median haynet, a discount in vitality consumption of 16% is achieved. If half of a very good high quality haylage haynet is changed with straw, the general discount in vitality is round 25%. These are actually vital reductions that would make all of the distinction to managing a very good doer to keep away from ulcers and can also be why Dengie makes use of straw as an ingredient in its vary of low-calorie feeds resembling Dengie Hello-Fi Molasses Free, Dengie Hello-Fi Lite and Dengie Ulser Lite.
4. Can I take advantage of haylage for a horse with ulcers?
The priority about utilizing a real haylage for horses with ulcers is that the fermentation course of used to preserve the forage produces acids. It’s logical to not feed a forage that has elevated ranges of acidity to a horse with a problem associated to elevated publicity to acid. Nonetheless, a extra correct description of many so-called haylages could be wrapped hay as they’re typically very dry, which has meant that little or no fermentation has occurred. This implies the degrees of acidity are not any completely different to a traditional hay which may be seen within the desk under.
A comparability of various forages:
A doable advantage of utilizing wrapped hay is that it could effectively have been harvested earlier and so is prone to be extra digestible, that means that the horse will do higher on it. Forages containing extra moisture and reduce earlier are sometimes softer and so could also be simpler for horses with ulcers to handle. They’re typically extra palatable, which is helpful for poorer doers who might not have a giant urge for food.
5. Can I take advantage of alfalfa for horses with ulcers?
The straightforward reply is sure, you may. Research again within the early 2000s confirmed that alfalfa was extra useful for horses with ulcers (ESGD) in comparison with grass forages, because the excessive ranges of calcium and magnesium it incorporates act as pure buffers to acidity. Alfalfa has actually deep roots – about three to 4 metres – and the calcium at this depth within the soil is extra out there for absorption. Which means alfalfa vegetation can take up extra calcium than grass – chopped alfalfa incorporates between 30 and 50% extra calcium than grass forages.
So why are some individuals involved about feeding alfalfa?
There has additionally been a research revealed that has induced confusion about using alfalfa. It explored the incidence of ulcers in foals and scoped them simply after weaning. The researchers discovered that foals fed chopped alfalfa had the next incidence of equine glandular gastric illness (EGGD) than these fed alfalfa pellets or hay. Nonetheless, you will need to think about that this was a really small research utilizing weaned foals.
Weaning is a really annoying time and stress is thought to be a major contributing issue to EGGD and so whereas there could also be correlation on this research, it undoubtedly doesn’t verify causation.
The identical analysis group have subsequently revealed different research evaluating grass and alfalfa hay in grownup horses. The horse with ulcers in the beginning of the research now not had ulcers after being fed the alfalfa hay, suggesting there was some protecting impact from alfalfa, as has been seen in different research.
