Prebiotics and Probiotics for Horses

Whether we like it or not, there are bacteria living inside us all--including our horses.  But bacteria gets a bad rap, usually.  Along with the harmful bacteria that can cause illness, there are also beneficial bacteria that help the gastro-intestinal system work properly.  Since horses ingest forage on a continual basis, these 'good' bacteria help with the process of fermentation of the forage in the gut.  They keep things in balance.  And horses are prone to many digestive problems when things get out of balance.  If a horse is exposed to a wide variety of plants which he can graze on, he will naturally consume these good bacteria.  Many horses are kept on overgrazed pastures, in dry lots, or in stalls, though.  These horses, along with very young or old horses may need a little help--a prebiotic or probiotic may be called for.

What exactly are probiotics and prebiotics?  Most people don't really know the difference.  Well, a probiotic a product containing live microorganisms that benefit the digestive tract. That's right--it IS the good bacteria!  Probiotics are good to feed during stressful situations such as long transport, changes in feed (which should always be made slowly), or after an illness, surgery, or round of antibiotics.  According to Dr. Kellon, VMD (my equine nutrition instructor), two good probiotics are Equine Generator and DFM-EQ.  You usually don't need to feed them long term though.

Prebiotics, on the other hand, are actually 'food' for the good bacteria.  They stimulate the growth and activity of the good bacteria.  Many feeds or feed ingredients such as beet pulp, flax, yeast, or psyllium are prebiotics.  You can feed them daily to promote a healthy gut.  Two great manufactured prebiotics are Ration Plus and Forco.  I personally feed Ration Plus and have seen its benefits.

So how do you know if you're horse could benefit from a pre or probiotic?  As I mentioned before, probiotics are good during times of stress and usually aren't fed long term.  Prebiotics are good for any horse, but if you're horse is having trouble holding weight, suffers from chronic diarrhea, is prone to colic or ulcers, has a poor appetite, or has poor coat/ hooves, he could very well benefit from a good prebiotic.  Of course, you should always check with your vet first (especially for chronic diarrhea cases).

Hopefully, I've explained the differences between pre and probiotics well enough.  It's important to know what you're feeding before you feed it!

Ta-ta!
