1. DNA is found in the nucleus of cells. Samples submitted for genetic testing are usually hair, blood, or tissue. Hair samples must contain the “bulb,” which looks like a tiny ball at the root of the hair. This is where the DNA is located. When submitting hair samples, make sure to pull, not cut, the hairs so the bulb is present. Blood and tissue samples require additional steps, such as an anticoagulant (for blood) or freezing (for tissues). Always follow the testing laboratory’s instructions for sample submission and contact them with questions.

Receiving a diagnosis of the condition behind your horse’s health or performance problem is usually a relief, but the satisfaction of getting the diagnosis can be quickly replaced by fear and uncertainty regarding what to do about it. Questions around both the long-term prospects for your horse and the costs involved to support the horse with such a condition can be daunting. Owners of horses diagnosed with special nutritional needs often feel bewildered and frustrated as they attempt to put together an appropriate management protocol.

Protecting Horses and Humans - The COVID-19 pandemic showed how alarmingly quickly a virus can spread across countries and continents and created an understandable reaction to protect against infection from any and all viruses and pathogens. By extension, it is also essential that there is a level of biosecurity on your farm or acreage to protect horses against agents of disease.

Stringhalt, or equine reflex hypertonia, is a neuromuscular condition that causes a gait abnormality characterized by involuntary, exaggerated upward movement of one or both of the hindlimbs. It looks like a jerk or hop, with the affected hindlimb(s) snapped up towards the abdomen. This generally occurs with every stride at the walk but can lessen at the trot and is usually absent at the canter. The degree of hyperflexion varies from mild to severe and is most obvious when the horse is turning sharply, backing, going down a slope, in the first few walking steps after standing still, or during gait transitions. A hopping gait may be exhibited in severe cases.
