The Pacific Northwest Endurance Rides Convention was located in Portland this January, so of course I had to attend. It was an absolutely wonderful time – I went to many panels and talks, perused the trade show, and finally met quite a few of the Pacific Northwest endurance riders and endurance newbies (like myself) that I have interacted with online over the course of a couple years. Everyone in this community is so friendly and it seems that horse people that like to GEEK OUT about their horses are particularly attracted to this sport. Just another reason I think it is a good fit for me: I can talk about nutrition and hoof care and what have you for hours and be as happy as a clam. I’m a total geek.
One of the several talks I took extensive notes on was Dr. Steve Duren’s on Feeding Management After An Endurance Ride. And without further ado, what I learned:
Alfalfa vs. Grass Hay
- It has more calories than grass hay, and endurance athlete need and use those calories. And it’s better for them to get calories in a forage source like alfalfa hay, because horses are meant to eat forage, not grains and lots of starchy sugars.
- It is a good bio-available protein source, which endurance athletes need to repair muscle.
- The excess calcium in alfalfa hay actually can help prevent ulcers because it acts as a buffer – and yes, this does mean that feeding some alfalfa hay PRIOR to exercise is a great idea (to help protect a horse’s stomach from acid splash).
- Otherwise, the nutrition expert said that the majority of a horse’s diet should ALWAYS be grass. Grass is what horses were made to eat, and the endurance athlete is no different in that respect.
As far as feeding grain (like corn, barley, oats & rice) is concerned, the points of the discussion mostly settled on a couple concerns and things to know and put into practice:
- No more than 4lbs of grain should be fed per day – 1-2lbs per day is better if there is a need.
- Grain should always be fed in as many feedings as possible.
- Grain should mostly be used to address a horse’s body condition (i.e. they are too thin and need more concentrated calories).
Endurance horse should always have some fat in their diet (this comes from your oily foods) because the equine body needs to be taught to eat and digest fats well (so you shouldn’t dump fats as a new feed on them during or after an endurance race). Fatty foods also have the added benefit of slowing down how quickly food leaves a horse’s stomach, helping to prevent ulcers.
Timing of Feeding
This was one of the most valuable aspects of this talk, because how different feeds were digested and therefore utilized by the body. In other words: when do you feed WHAT before, during, and after, an endurance race?
- Feed “grain” (anything other than forage-type feeds) at least FOUR hours before a ride. This allows the horse to digest and store the energy in time for exertion.
- Feeding grain right before a ride can cause problems because the energy isn’t available and they are spending energy and water digesting rather than that energy going to the muscles and the water being available to cool the horse (through sweat).
- “Grain” during a vet check won’t do any harm because you haven’t stopped exercising.
- After a ride your goal should be to erase the nutrient deficit created during the ride (water, and energy in the form of calories).
- If a gut is full of forage-type foods, it can hold and store more water. And yes, you WANT this. So free-choice forage foods (hay, beet pulp) are always good.
PHASE 1 – within the 24 hour period after a ride.
This is when the horse is the most depleted and the equine’s metabolism is still revved up, the gut disrupted. The first thing to ensure is that you correct hydration – allow them to drink! If a horse isn’t drinking enough an IV may be needed to monitor their water intake more closely. If they aren’t drinking they can crash very quickly.
In this phase, horses should get whatever FORAGE they will eat. This means: free choice hay and grass, in whatever type they will eat. Forage also usually has a lot of potassium, which is an electrolyte. If they are eating forage their thirst process will be triggered.
Grain in the first 24 hour period should be fed to replace depleted muscle sugars and rebuild muscle glycogen stores (it is fueled up with ATP = stored sugar) so that the horse’s muscles will recover faster. As far as timing in this is concerned, it’s best to feed grain within 1 hour of finishing.
As far as feeding electrolytes POST-race, it was noted that eating and drinking should come well before supplementing with electrolytes.
PHASE 2 – two to three days post-race.
Hauling a horse has high energy requirements, so it’s important to take that into account as you head home. Forage should still be free-choice at this stage (I’m sensing a theme) and grain should come in smaller portions, more often. Probiotics are a good idea at this stage as well, to help get the equine machine working seamlessly again.
During this phase some low-key exercise is a good idea to keep everything moving towards the state the horse was in before the race. Assuming the horse was better before the race than they are afterward.
PHASE 3 – four to ten days post-race.
Horses may have rapid weight loss during this phase as they replenish their stores, but their soreness and tiredness should be less. At this stage, you guessed it, feed a lot of fibrous forage! Fiber is burned for energy in the presence of oxygen, which is what endurance horses need.
|Deli prefers fresh grass over anything.|
Fat should be fed in this stage in good quantities, though you should have been feeding fat all along.
Again, some easygoing exercise is going to help a horse recover more quickly going into this phase.
I took copious notes on this topic because I am a serious NERD for equine nutrition in general. If someone gets me started talking at my barn the conversations usually ends with them slowly backing away from the flood of information spewing from my mouth. I think it surprises them because I really am a quiet and reserved person. Normally.
At any rate, stay tuned for PART 2 of feeding the endurance athlete!
