Evolving Feed Programs

I get the occasional e-mail from people with questions on previous articles I've posted on what I fed my horses.  More questions are specifically asking about prevention of sand colic. Katie and BL would be the last two I received - this article is for you.  It is intended to show you want I do.  You would be well advised to work with your Vet on what is going to be best for your horses in your specific area.

A significant portion of horse owners have the benefit (and sometimes the dangers as well) of keeping horses near yearly on pasture. In West Texas and the desert Southwest, putting your horses on pasture is rarely an option. And if you own horses long enough you will see a case or two (or three or ten!) of sand colic.  I saw a lot of it when I ran a large public barn.  And, in my observation, the rates of colic increased when horses were fed straight alfalfa and consumed much of it of the ground.    

Sand colic of course is distress or even an impaction of the gut caused by the digestion of sand. If you want to get concerned about sand colic, goggle the term and look for x-rays and pictures of necropsies showing just how much sand a horse can accumulate in their gut. 

While for centuries, horses grazed off the ground, it has usually been plants and scrub. The tendency of a horse to pickup sand in his feed increases greatly when small alfalfa leaves or grain is dropped onto the ground and the horse cleans up every bit of it. Generally, horses can eat long stemmed forage, such as grasses off the ground without a problem, but feeders, and mats, that will contain the feed of the ground is generally safer.

I used to feed in tubs that were small enough where the horses would pull out their feed and distribute it on the ground, where they would pickup sand while cleaning up. As a preventative step, I used to routinely feed a wheat bran mash, usually mixed with Sand Clear - a pelleted psyllium supplement, to help remove sand from the gut. This also presented it's own issue with horses (some more than others) dropping mouthfuls of the mash onto the ground then cleaning it up digesting more sand. It was only when I went to using large box feeders, where the horses would drop very little feed outside of their feeder, where I could cease the routine feeding of bran mashes.

This is the evolving part of a feeding program for horses. As factors change, so does what and how you feed.  Many factors would influence changing types and amounts of feed- these are just of them:

~ As horses get older their dietary needs will change. We've kept horses rideable into their late twenties and even early thirties by adding judicious amounts senior type feed to ensure these great old horses obtained a healthier amount of vitamins, minerals and pro-biotics their aging bodies need.

~ Teeth issues, causing pain to chew or inability to chew food small enough is a big facto.  Older horses will generally have teeth problems.  And in fact, all horses can have teeth issues so nothing better than an annual exam and floating to eliminate teeth as an issue.  While you are at it, have a conversation with the Vet on what types of feed will benefit the changing health of the horse.

~ Changing sources of alfalfa and grass hay, with changing quality and nutritional value, will also likely move you to change your feedings. we feed a mix of alfalfa and grass hay and that ratio changes as we detect quality changes in the hays. First cut alfalfa, with it's normally rich leafy and higher protein values, direct us to feed less alfalfa and more grass.  While you can normally find a nearby asset to send feed samples to for diagnosis, the horse owner usually develops a feel for the feed quality through sight, touch and smell.
 
~ Several of our horses receive a periodic dose of pro-biotics and when we change alfalfa sources, all the horses get another dose even though we mix old and new alfalfas for 7-10 days. We also give them an out of cycle dose of Sand Clear as well.

I do routinely use Sand Clear. Some people have commented that it's expensive, but having a Vet respond to a colicing horse is more expensive. Horses are going to be different - some get along just fine without the intervention of added psyllium. I have three horses who get one scoop (5 ounces) of Sand Clear once a week. Nothing indicates that they digest much sand, but Sand Clear isn't just helpful to prevent sand colic, it's helpful to keeping a healthy gut. And two other horses get Sand Clear two to three times week depending upon the condition of their manure.

As a rough 'sand in the gut' check, You can collect five or six balls of manure that haven't touched the ground and put them into a mason jar.  Cover the balls of manure with water; shake the jar up, and let the sand settle to the bottom.  While I have done this dozens of times, I no longer bother to do.  I can usually judge by changes to the horse's manure piles on the ground.  Wet, partially formed manure can indicate sand in the gut. We have been able to keep two of our older horses pretty well balanced this way for years, and actually eliminated the periodic colicing of one of these horses when we first came to us.

My Vet runs a large stables and her practice is that all horses receive Sand Clear once a week. The fact that she recommends it should be good enough for most of her clients. I do still believe wheat bran has a place in the barn. A sloppy wheat bran mash with a bit of molasses (and I usually put in some corn oil) is a good way to get fluids and nutrition into a horse.

So to answer several questions over the past few months, and those from Katie and BL, I obviously recommend Sand Clear.  However, not all psyllium products are the same. I would be hesitant to use psyllium products intended or humans, and would not use any of these products that had artificial sweeteners added to make it palatable to humans. Metamucil for instance contains Aspartame. No human could consume Aspartame, and neither will my horses.

Judging Your Horse's Manure

If you are like me, you are always evaluating your horse's manure, whether in a stall, corral or on the trail. Sometimes I'll be riding with people who see me do a short circle around a manure pile that my horse just dropped and sometimes I get asked why? The reason I do this is that you can get an idea on the health of horse or maybe get a lead on emerging problems by evaluating their manure.

I'm not only looking at what the manure looks like, but how many piles that horse will drop in a given day, and each horse is different. My quarterhorses and grade horses will drop 9 to 12 piles a day, while my Mustang only drops 6 to 7 piles a day.  Any quantity much different and that horse bears watching just a little more closely. 

Each horse's normal manure will look different. Some horses normal manure will be flakey and sometimes break apart when hitting the ground; other horses may drop smaller piles with balls more roundish than not; and yet others may drop egg shaped balls. If I put all my horses in one corral I can tell what manure pile belongs to what horse which is helpful on determining if any one horse is dropping significantly less piles than normal, which can be indicative of a looming problem, usually dehydration and subsequent colic.

Normal manure is generally formed manure balls that appear to be a little wet. If they are not glistening with moisture then I would not get worried unless they appear to have a mucous type covering.   After a while you'll know what is normal for that horse and what is not. The picture of manure at right is pretty normal.

Very dry piles can lead you to believe that the horse may be hydrated. Sometimes I'll soak his hay in water for a couple feeding to see if he gets moisture back into his manure. If I have been watching that horse then I see mucous on the manure then I would absolutely call my Vet. 

Manure piles that are somewhat or mostly unformed, like the picture at left, could be a result of sickness or discomfort, from sand or a change of feeds.  The manure in the picture wouldn't spin me up unless it started becoming worse - wetter and less formed.

Runny and unformed manure piles, almost looking like a cow pie, can be indicative of sand in the gut. My Vet tells me that some horses can have as much as 80 lbs of sand in the gut. The horse's system will drive fluid to the gut to help remove it, hence the wet unformed piles. Dehydration becomes a real threat from this.

You can test for sand by collecting some of the manure that hasn't contacted the ground and put it into a quart sized ball jar. I'll put about 3-4 inches of manure in the jar, then fill with water, shake and let it settle for 15-20 minutes. If there is sand in the gut,  it will settle to the bottom of the jar and be visible. The picture at right is manure, like a cow pie, likely caused by too much sand.  And while it is likely feed issues cause digestive problems which you see in the manure, I also think that, in some horses, their manure can show increased stress. 

If sand is present, especially in any quantity, you need to take action. I will never hesitate to call my Vet, but I also try to stop problems before I call her. I use Sand Clear, a pelleted psyllium seed husk supplement, that I add to my horses fortified feed for a five day period every 4 to 5 weeks, and on one horse in particular I usually put him through a 10 day regime of Sand Clear once every 4 - 5 weeks as he seems to take in more sand than the other horses.

I think that some horses, particularly older horses, may benefit from pro-biotics.   I feed pro-bios in paste form, about every six days, to a couple of my horses.  While I think it may be helpful, I just don't know for sure.      

Another thing to look for in your horse's manure piles is bits and pieces of undigested feed. This can be because your horse is not chewing his feed completely enough - maybe a problem that can be fixed with getting his teeth floated.  Again, preventive care in the form of routine dental exams is a good idea.  Have a safe, and healthy journey.  

Comment on Loose Horse Manure

Bill M. left a new comment on a previous article about Common Horse Problems – Loose Manure: ”I have a 30 year old quarter horse who has the patience of a saint for this. His manure is sometimes loose because of his age and digestive tract. I first learned years ago that the condition of the poop was the condition of the horse. He also likes his butt to be washed and baby oil on it after washing. Probiotics does help and it seems he will get it till trails end.”

Hey Bill, I also have an older former roping horse (Roy) with a loose manure problem. He’s coming 28 this year. I think his problem is a combination of both ingesting sand (hey, I live in the desert), and his reduced or compromised immune system. I give him a bran mash once a week and once a month I put him on Sand Clear for a week. After this his manure becomes more solid, so ingesting sand has to be some of his problem, even though from time to time I place some of his manure balls into a glass jar and fill with water to see how much sand I can separate from the manure.

Roy does well. He is rideable and has a lot of energy. He is the horse I posted a recent video on tying the Mecate reins into a lead rope. I too, have to clean his butt a couple times a week and spray mineral oil. He’ll get this care until the end of his natural life.  And he's worth it as he's a damn good horse.  As my wife says, "Put a child on his back and Roy thinks he's transporting fine china."

I have used probiotics quite bit before, I think I used Pro-Bios last, but currently am not on a regular routine with them. Thanks for the reminder on them. I would be interested to know what brand or type you use. Thanks for the comment. Safe journey.
