War Horse: The Movie! Trailer of Spielberg's Film Premieres; Meet His Equine Artistic Adviser

War Horse. Steven Spielberg. Dreamworks. Disney. Get ready to put it all together! Watch for the Disney/Dreamworks Hollywood film version of the hit London and Broadway stage play. You'll be able to see it in about six months; the tentative release date is December 28 in the United States.

The War Horse story took on another dimension today, with the release of the first trailer promoting the film version of the hit stage play.

If this trailer is any indication, it looks like Steven Spielberg's amazing directing talents easily extended themselves to showing horses in a very realistic and appealing light. And that's not easy to do!

Sure, the story of War Horse is epic, and a great one. But the horses could easily have ended up looking like stick figures, or limp two-dimensional background objects. Not every film with a great horse-related story line succeeds in showing horses both realistically and inspirationally. The Black Stallion and Phar Lap are two from the past that I think did do it well.

What did horses look like during World War I? How could today's horses be made to look like yesterday's? What about their manes and tails and tack? Yes, even their shoes? Spielberg needed some help there. (©Disney/Dreamworks publicity photo)

When they went looking for a horse to play Joey, the star horse of the film, I think they went to eventing yards. What do you think? Irish-bred? Yes, the mane is too long, you're right. But could it be that's intentional, to make the horse look like he would have during World War I? Ali Bannister would have had a hand in that. Who's she? Keep reading!

Note: for some reason, only the first minute or so of this audio file is playing. I'm sorry. The full file is playing on the Hoofcare and Lameness Facebook page (http://www.facebook.com/hoofcareandlameness); I'll try to fix this file if I can.

Take a break and listen to this BBC Radio interview with British equestrian portrait artist Ali Bannister, who literally woke up one morning to find herself and her artwork and her design talents on the set of War Horse. Ali's title was "Equine Artistic Adviser". And while there may be no Academy Award for makeup and hair styling of horses, there is no question that the authenticity of this film rests on the portrayal of the horses as looking like they would have for the time period, and for their work on English farms and in the war. Ali shares her experiences in this first of many interviews.

Here's a sample of Ali Bannister's horse portraiture; watch Theo come to life. You'll see why Spielberg chose her! You can see lots more, and commission Ali to paint your horse or dog, at http://www.alibannister.com.

This video shows scenes of the making of the film in Devon, England last year. Note: the release date is mentioned as August, but it has now been pushed back to December.

If you're new to War Horse, it's both a play and now a film-in-progress based on a best-selling children's book by Michael Morpurgo.

The synopsis, from Disney/Dreamworks Films publicity: The First World War is experienced through the journey of this horse—an odyssey of joy and sorrow, passionate friendship and high adventure. War Horse is one of the great stories of friendship and war— a successful book, it was turned into a hugely successful international theatrical hit. It now comes to screen in an epic adaptation by one of the great directors in film history.

Translation: Yes, of course. But there's more to it than that. War is too painful a subject sometimes to tell from the human perspective. People have built-in defenses in their subconscious selves, to protect them even for the time spent viewing a Spielberg film like Saving Private Ryan or Schindler's List. But when you can show how war affects an animal that has no choice in the matter, people allow themselves to feel something--about animals, about humanity, about themselves--they might not otherwise let slip.

That's War Horse, in a nutshell. You feel it slip, and you let it. It's about a horse, so it's safe to let it slip. But of course it is about much, much more than a horse.

Special thanks to Kentucky equine photographer (and friend of Hoofcare and Lameness) Wendy Uzelac Wooley of Equisport Photos and her late, great ex-racehorse Jaguar Hope, who even after his death is doing amazing things. A sketch of Jaguar Hope by Ali Bannister appears on the Dreamworks crew logo caps for the War Horse film. I highly recommend Wendy's Racehorse to Showhorse blog for anyone who wants to see great photography presented in an upbeat format. Her contributions to this blog have added a lot and there wouldn't be a Hoof Blog without the support of generous, creative, collaborative-spirited people like Wendy.

Video: Fix My Crooked Foal! Reality Time for Horse Breeders, Skill Time for Surgeons and Farriers

It's that time of year. The 2011 foal crop is here and breeders are looking at them under magnifying glasses. What have they bred? Will this foal make it as an athlete in the long run?

In the short run, will he or she sell at a yearling sale?

Making a foal look and move like a future athlete is a controversial part of horse production. Many foals are born with problems, so corrections are often made. Some are left to see if time, weightbearing and chest or muscle development will compensate for the appearance of a bow-legged or knock-kneed conformation.

Many would say that corrections should have been made in the selection process of matching broodmares and/or stallions instead of later, in the foals, but the prevalence of conformational defects in so many breeds would make selection based on ideal conformation a daunting task, particularly since a horse's original lower-limb alignment may have been surgically altered to some degree.

In 2011, a sire or mare's true conformation may be better seen in the foals he or she produces than in the legs he or she stood on when breeding publicity photos were taken.

This is the time of year when veterinarians and farriers find themselves holding squirming foals and truly working together to decide what should or shouldn't be done to straighten the appearance of the lower limbs. These are important decisions.

The same principlws used to improve the limb alignment on a valuable Thoroughbred or show horse foal can be used to intervene when a foal is born with more severe defects. Surgery and special shoeing probably saved this foal's life. (Photo from the Wildenstein Photo Library, thanks to Michael Wildenstein.)

Knowing the bloodlines, knowing the breeders, and most of all, knowing the anatomy and growth schedule of the lower limbs are the keys to success. What might work at one farm won't work at another. What might work on a Quarter horse might not work on a Friesian. And what works at one clinic or hospital might not work at yours...but you know what worked on this foal's half-brother, or you remember its dam, or you know the farm staff is going to diligent about caring for this little guy (or not).

The video team at Thoroughbred Times caught a typical moment with a surgical team at Hagyard Equine Medical Center in Lexington, Kentucky this spring. This brief two-part video follows one foal from evaluation through minor surgery and application of a lateral hoof extension aimed at bringing a toed-in foot back into line with the limb.

Part 1: Identifying toe-in conformation with Hagyard Equine Medical Institute's Dr. Michael Spirito

Part 2: Periosteal elevation of the fetlock and application of an adhesive lateral extension on the toed-in foal's foot.

And what if the foals weren't corrected? Toed-in, toed-out, club-footed foals grow up unaltered in the fields of breeders without the budgets of business-oriented breeders. Most people feel strongly that correction early in life gives a foal a chance to bear weight correctly and therefore develop normally so that, as an athlete, the horse has a better chance of running. And winning.

But would they have straightened out on their own, without the pressure of yearling sales for racehorses and in-hand classes for show horse yearlings?

There's no question that the correction has to be done at the right time, before the corresponding growth plates in the area of the deformity close. Wait-and-see is a decision of its own. Conservative trimming techniques can sometimes be enough. A tiny extension like the one shown in the video can be used with or without surgery, and surgery, as shown in the video, can consist of conservative periosteal elevation or more elaborate screw insertion to impede development on one side of the bone.

The idea is to help the foal, and give it a chance to be the best athlete it can be, considering the legs it was given.

Foot Photos: Totilas Used His Shoes at German Dressage Championships at Balve Today, Set New German High-Score Record

New rider, new trainer, new stable, new vet, new farrier...Dressage World Champion Totilas seems to be putting it all together and, with luck, hit a new kind of stride.

Under new rider Matthias Rath, the horse who won all three gold medals at the 2010 Alltech FEI World Equestrian Games for the Netherlands is hoping to be crowned champion under a new flag this weekend at the German National Dressage Championships at Balve. In today's Grand Prix, the black stallion set a new high record for a German horse, with a score of 81.021.

Excitement is building for the musical freestyle portion of the championships, where the new music for Totilas will be heard in its entirety for the first time. It was composed/created/compiled by music producer and dj Paul Van Dyk and has been widely touted in the international music and entertainment news.

Luckily for us, Ina Fassbender was on hand to take these photos. Totilas's new farrier is Franz Helmke, who is also farrier to Isabell Werth. As previously reported, Totilas's shoes have been changed from the simple open-heeled shoes he wore under Dutch rider Edward Gal, finetuned for him by Dutch farrier Rob Renirie. The new left hind would be described as a lateral extension shoe. Totilas's heart-bar shoes are explained at length in a previous Hoof Blog post.

Totilas is now shod with heart bar shoes in front and a combination of lateral adjustments on the hinds. The right hind would be described perhaps as a thumb print heel with a kicked-out trailer on the lateral branch.

It's easy to see why Grand-Prix level dressage horses often receive increased lateral adjustments in their shoes. The pirouette requires the horse to lower his haunches, elevate the front end, turn...and not move forward. The test will require the horse to do the pirouette both to the left and to the right, to demonstrate balance.

In this Alex Domanski photo of Totilas schooling at home, you can see where his hind fetlocks are headed in the piaffe. Also, notice the equipment he wears: lined bellboots and wraps in front, but behind he is wearing a full-length wrap/boot combination, similar to the one-piece stretch-and-flex "spats" (my nickname for them) sold in the USA by the British company Equilibrium. The one-piece construction prevents the inevitable rubbing between a bell boot and a leg wrap or boot, which can pinch or irritate the pastern and heel bulbs on the hind leg. As with any leg gear used during training, these boots have to applied properly, however, or the horse will be annoyed.

Thanks to Alex Domanski and Ina Fassbinder for aiming their lenses at the hooves.

Grazing Muzzles Reduce Pasture Consumption by 80 Percent in Grazing Ponies, According to New Study

"It's not funny!" this horse seems to be saying and there's no question that most horses are less than amused at the prospect of wearing muzzles. Would it be different if all the horses in the pasture had to wear them? This expressive photo is by the talented animal photographer Judith Whelan.

New research, presented at the Equine Science Society (ESS) Symposium in Nashville, Tennessee last month, shows that using a grazing muzzle can reduce the pasture intake of ponies by over 80 percent.

When horses and ponies, in particular, are given free access to grass, they appear to be more susceptible to obesity and related disorders, such as insulin resistance and laminitis, than are those with restricted access to grass.

However, simply reducing the amount of time a horse or pony is allowed to be out at pasture may not be as effective as previously thought. Another study, also presented at the ESS meeting, has shown that ponies may adapt their grazing behavior to eat more in a shorter time.

The new research shows that the use of a grazing muzzle could be a much more effective and reliable solution if used appropriately.

Grazing muzzles significantly reduce bite size and intake. Anecdotally, ponies fitted with grazing muzzles spend a greater proportion of time engaging in foraging- and eating-directed behaviors than their non-muzzled counterparts, yet they still either lose weight or retain an established, trim body condition.

The study, which was conducted by the British-based Waltham® Equine Studies Group in collaboration with Dr Annette Longland of Equine Livestock and Nutrition Services in Wales, aimed to quantify the effect of wearing a grazing muzzle on herbage intake by ponies.

Four mature ponies were recruited for the study. After an adaptation period, their pasture intakes were determined when wearing a grazing muzzle and when grazing without a muzzle. Pasture samples were obtained daily to assess the grazing available. Insensible weight loss (ISWL) was determined for each pony immediately preceding and immediately following each three-hour grazing period. Intakes were determined by changes in body weight (after taking into account the weight of any feces and urine produced plus the estimated ISWL) after the three hours of grazing, using a calibrated weighbridge.

Pasture intake by the ponies grazing for three hours without muzzles averaged 0.8 percent (with some eating close to 1 percent) of their bodyweight. This is the equivalent of up to two-thirds of the recommended daily dry matter intake for many ponies on restricted diets.

Funny Cide is NOT amused by his new grazing muzzle

Even Kentucky Derby winners have to wear grazing muzzles. Here's Funny Cide, looking like he's saying, "Don't you know who I am? Don't take my picture when I'm wearing this thing!" in his paddock at the Kentucky Horse Park. (Sarah K. Andrew photo)

Owners therefore may under-estimate pasture intakes of un-muzzled ponies, even when they are provided with restricted time at pasture.

In contrast, the pasture intake of the ponies when wearing muzzles was around 0.14 percent of bodyweight over three hours, representing an average reduction of 83% percent compared to when they were not wearing muzzles.

Clare Barfoot RNutr, is research and development manager at Spillers®, a British feed company. Her comment on the research: “These figures clearly show how effective grazing muzzles appear to be as a method to restrict pasture intake. The study has given us helpful, practical guidance on how we can safely manage grass intake to control weight gain and reduce the risk of obesity-related disorders, without significantly compromising the natural behavior and wellbeing of our horses and ponies.”

Grazing muzzles must be used with care, should be properly fitted and horses and ponies should be adapted gradually to wearing them. Group and individual behavior should be monitored closely to observe any potential concerns caused by changes to the herd dynamics. Total exclusion muzzles are not advised.

Silent Anvil: Buster Conklin, Retired Cornell Vet School Farrier, Has Died

Say good-bye to Marshall "Buster" Conklin of Horseheads, New York, one of the great faces and spirits of late-20th century horseshoeing in America.

Buster was the longtime farrier instructor and resident farrier at the Cornell University College of Veterinary Medicine but he will be remembered much more for his character and his passion for his profession than for any job he held. After all, no job could quite hold a man like Buster Conklin.

I'm sure more information will come in and I'll think of something to say but not quite yet. Just "good-bye, Buster" for now.

And definitely, "What a guy".

Please check back for more information. Photo © Fran Jurga, Hoofcare Publishing.
