Just a reminder that elections are coming; vote horse friendly

Just a reminder that elections are coming; vote horse friendly

In the past 40+ years we have learned an awful lot about horses’ health. Colic surgery, which was all but unheard of, has pretty high success rate numbers. Wounds have better potions, lotions, and dressings. There are many newer and more effective vaccines and we have made Equine Infectious Anemia (EIA, what the Coggins test is for) a side issue instead of the dominant state it held in the ‘40s.

But we still don’t know a lot, and what’s amazing, when you listen to us talk, is that we don’t know we don’t know! The snake oil is still out there and out there with endorsements, official looking labels and massive amounts of shelf space.

I was reminded of all this recently at a Rutgers Equine Science Center meeting. Rutgers is not a veterinary college, but is involved in a large number of equine studies. Their aim is prevention rather than cure and they have done a lot of research on performance enhancing drugs and nutrition.

What don’t we know about what we do? Lasix is a good example. The race industry sought a cure for bleeding out the nose during a race. Blood dripping out the nose or wandering around the lungs gets in the way of air-flow and you need every hemoglobin molecule to deliver oxygen during a race. Lasix became the miracle cure. But there was still evidence of bleeding.

Enter Dr. Kenneth McKeever, who is massively tall, you know when he has entered a room. He and the Rutgers Equine Science Center started doing treadmill studies on how Lasix works. Turns out it doesn’t harm the horse –– doesn’t stop the bleeding either. But it does act as a diuretic, dropping pounds of water before a race so the horse runs lighter and faster. Voila! Now everyone uses lasix to make a faster running horse, or you could just watch the animal’s water consumption pre-race.But people still think Lasix stops bleeding.

The evidence for clenbuterol and albuterol was different. The medication was found (being used off label) to build a horse faster, so a yearling would look like a 2-year-old and fetch a better asking price. McKeever again researched the evidence. He found that indeed it does build a bigger horse, with a faulty heart. So while that horse looks like a prime athlete its performance will suffer and the very real possibility of a heart attack looms.

Now let’s look at those shelves of nutraceuticles and advertisements from feed producers. NRC 6th editionLet’s step into the world of the National Research Council. They are the defining body of nutrition requirements for humans and animals in the U.S. and many other countries. All the information on the foods in your refrigerator is based on the NRC requirements. The  equine folks over there (all with extensive initials after their names) review the world-wide base of scientific research. They look at the quality of the research, size of study and consistency among results. They’re good at what they do. So it was a wake-up call in March of 2008 when I attended a conference addressing the most recent revisions to the equine recommendations. Dr. Laurie Lawrence, chair of the project, started by saying how little they actually know about the equine’s metabolism and use of nutrients compared to other livestock.

The reason is simple; we don’t feed and euthanize horses to study nutritional effects. It is a moral taboo. Despite the outcry of horses used for human consumption in other parts of the world, it would appear it is not a significant dietary mainstay, because worldwide there is a dearth of information on nutritional effects on a horse.

Progress is being made. Clever scientists and better imaging equipment are allowing peaks into blood markers and invisible organs. But it is still expensive to run trials on horses because it is expensive to keep horses. So progress is slow. When engaged in “What do you feed” talks, it always makes me stop and ask “how do we know this.” The answer is usually because the trainer, who is on the Olympic list, or the feed supplier said so. Alas, thhey have no initials behind their name. And vet schools are just now catching up on the nutrition angle, but they can’t teach what isn’t known.

If we really want the scoopy on that new feed or additive it is worth a call to an equine nutritionist associated with a university or the government. Ask them if research has been done on the component in question. If the answer is no, you may still decide to use the product, no doesn’t always mean bad, just that we have no idea how the component affects the animal. Sometimes, though, no can mean danger – you get to decide.

But at least you will be able to smile and listen to others talk and know what we don’t know.

sitting on artillery in Iraq

hot and tired in Iraq

On warm days a good nose can tell which stall the smell of ammonia is coming from. Today it’s in T-man’s and Moke’s. We’ve had spring-like pasture all summer and I just got a load of new hay. The combination tipped the scale on protein. For once my mind didn’t hang around grazing with the horses, instead it shot to the container of protein supplement I just sent my soldier son in Iraq. His unit is always working out and trying to build muscle so he bought out the store when he came home for his two weeks R & R.

His unit is stationed in the south of Iraq and has lived the summer in 120-130 degree heat. Add in 50 pounds of full battle-rattle and their socks are soaked with sweat running down their body before they walk out the door. Dehydration is a serious enemy where they are.

And do you know what your body does with most of the excess protein you eat? It gets rid of it, washes it right down the toilet.  So I’m concerned about my son taking a protein supplement in the heat and becoming dehydrated. I’ve been spending a lot of time trying to educate him about protein and heat and that brought me back to the horses.

Because they handle protein a lot like we do.

Some excess protein goes into fat, but most excess protein is broken down in the kidneys and excreted in the urine. One of the elements protein breaks into is ammonia. Anytime you get a strong ammonia smell in the barn, someone is most likely gobbling more protein than they need. It’s a pretty effective indicator.

Normally I don’t obsess about that. But thinking of my son made me realize I need to do a better job of regulating my horses’ protein through the hot summer months. The Army can and does mandate how much water my son needs to drink each day in the field. But I can’t do that with my horses. Unless I syringe the water into them, I am at the mercy of their thirst indicator and urinating doesn’t always trigger the idea to drink more water.

My guys lose buckets of water in sweat during the summer. Being Icelandics with thick skin and deeply embedded veins, there are weeks when they are drenched in sweat just standing still in the shade. I rinse them off, put them under fans, elect not to work them on “Bermuda High” days, ride in the cool of the day, ride in shady routes, and ride in the river. I do everything I can to cool their body–– yet I never think about the excess protein they are eating and how much liquid they are urinating because of it.

I’ll keep it simple. Just imagine their body as a big bag of water. If water is oozing out through microscopic pores AND through a small hole in the bag, the end result is less water in the bag at a faster rate. Now the bag needs a certain volume of water in it to make it function at its maximum. All that water loss compromises the bag’s function. Not even going to think about the way that changes the concentration of electrolytes and blood ph.

I don’t know of too many riders, aside from the endurance folk, who even think about dehydration as a contributing factor to a poor performance in the ring or on the trail. A number of riders add electrolytes when their horses are sweating. I sure do, and do you know how I add those electrolytes? I add them with a cup of high protein grain so the boys will eat it. I feel my head molding to the shape of Homer Simpson’s –– DOLT. I just gave them a supplement to help them keep and retain water in a supplement that will make them eliminate water.  ( for the science bent- I am well aware of the other functions of electrolytes- I’m just dealing with hydration at the moment.)

We are heading into our cold months here in Jersey. Indian Summer will keep the grass strong and growing for another 2-3 weeks and then the rich green will die off and the smell of ammonia will dissipate. I’ll have the whole winter to ponder the problem. A lot will depend on the climate. Another great growing season means I really have to do something. If the rains stop early and the sun dries up the grasses, I’ll be able to skate by. Whatever the outcome, I am putting “Hydration” on my list of suspects next time my guys just aren’t “right.” I hope my son does too.

Dare I say it, we are having an election this year and it is making me fearful for my horse. But my horse, who is not registered with any political party, is taking me to task about securing his future. Specifically he would like something in his water bucket when he needs to cleanse his pallet.

Water glistens from every corner of New Jersey in an aerial view; yet, we are running out of water. You see, all that glistening water is running off to sea and is not available for my horse to drink. Or for me to drink for that matter.

Granted we are johnny-come-latelys to the water issue because we have been blessed with an abundant supply. New Jersey is  the most densely populated state in the nation and all those houses, roads, offices, and swimming pools are impenetrable to rain drops seeking a way into the ground and back into the water supply. Instead those little drops of life roll down the impervious cover right into a drainage system that floats it off to a river and out to the Atlantic. Forever out of the reach of Moke’s water bucket.

This year we have a ballot question. Will the residents allow our heavily indebted state to take on a new $400 million debt to purchase open space. I suspect a few other states may be asking a similar question. It’s a tough call during these hard economic times. And sad to say, most residents are thinking, ball fields, soccer fields, parks. Instead they should be thinking food supply and water. The open space issue in New Jersey designates that 40% of the money go into farmland preservation, but all of the open space (sans parking lots) will allow the rain drops to go back into the water supply.

New Jersey hasn’t hit the critical point that so many of our Western states have hit. But it’s coming, it’s coming to all the states. We would probably do ourselves a service to include in the ballot description, “and to provide a rechargeable source of water for the state residents and animals.DSC02388

So Mokes has pushed me out the barn door and stamped that I need to use my squeaky voice and ask people if they have thought about open space and water. He has a whole list of other things he wants me to find out about and ask people about too. ‘Cause he is scared about his future and horses have a way of making you move if they’re scared.
