More on bones I just recently ran across the interesting and informative article “Bones Speak Volumes” (Conformation Insights, EQUUS 482), and I have an observation I would like to offer. I am director emeritus of the Spanish Mustang Registry, founded by Robert E. Brislawn and others. Bob, or Mr. Mustang, as I knew him, was very much interested in bones, and he passed that interest to me. He was especially interested in the importance of the cannon bone and the lumbar vertebrae, as Deb Bennett, PhD, also discussed in great detail. Bob classified mustangs’ lumbar vertebrae as having five, six, or five plus another (partial) piece of one. He was of the conviction of five being the purest. I have personally examined the skeletal remains of approximately 20 Spanish Mustangs. My observation was that…

which scents help horses relax?

If you’ve ever lit a scented candle to help yourself relax after a long day, you may not be surprised to learn that the smell of lavender can help calm stressed horses. Researchers at the University of Arizona recently measured cardiac parameters in eight dressage horses before, during and after they inhaled humidified lavender essential oil. Each of the horses was also tested with plain water to serve as a control either one week before or one week after the lavender trial. The experiment was then repeated with the chamomile essential oil. During the study periods, the horses wore monitors that collected data on heart rate as well as heart rate variability (HRV), the time intervals between heartbeats. HRV is an indicator of the parasympathetic response of the nervous system, and HRV…

ANTIMICROBIALS CAN AID HEAVES THERAPY Some horses with heaves may benefit from antimicrobial medications in addition to conventional treatment, according to a new Canadian study. Researchers at the University of Saskatchewan examined 11 horses with a history of severe equine asthma, a narrowing of the small airways of the lungs commonly referred to as heaves. Along with the classic clinical signs of the condition---including labored breathing and flaring nostrils---the horses were found to have bacteria in their airways and elevated levels of white blood cells in their lungs, which is a sign of inflammation. The correlation between heaves and airway bacteria isn’t well understood but may be significant, says Julia Montgomery, Med Vet, PhD, DACVIM (LAIM). “With everything we are learning about the microbiome, including new diagnostic non-culture-based methodologies to detect bacteria, we…

WHAT DARKER DAYS MEAN Dwindling hours of daylight may leave you feeling rushed and glum, but the shorter days of winter can have a different effect on your horse. Here’s what they mean to him: • A thicker coat. Winter hair coat growth is triggered as the number of daylight hours decline, a process that started way back in midsummer. By the time the sun is setting in late afternoon, your horse is probably plenty fuzzy. As days begin to lengthen again in mid-December, his body will begin receiving hormonal signals to shed his winter coat and new summer growth will begin, long before you’re thinking of spring. • Night vision. Although a horse’s eyesight doesn’t change in the winter per se, the shorter days allow him to put his superior night vision to…

the helmet question

Few topics spark as passionate a debate among horsepeople as the need for riding helmets. The question of whether to wear protective headgear is deeply personal, and it cuts to the heart of how we identify ourselves as equestrians. Many of us---especially those of us born in the 1980s or earlier---grew up admiring horsemen and -women who wore either Western hats or velvet hunt caps. Our heroes did not wear protective headgear, and neither did we. (In fact, apart from jockeys and polo players, almost no one did in those days.) But what if we could set aside all of the emotional history and take a fresh look at head protection, just as we consider new research into saddle fit, feeding, veterinary care and just about every other aspect of horsemanship? Whether you…
