Sometimes doctors can find out that a baby has a congenital disorder before its birth.

Clinical signs of epiglottic entrapment include inspiratory and expiratory respiratory noise during exercise and poor exercise performance. Less common signs include cough, nasal discharge, and head shaking.

- Conformation in Thoroughbred Yearlings StudiedBy Kentucky Equine Research Staff · November 15, 2007. There is a belief among many people that defects in conformation predispose racehorses to poor performance and injury, and horses with obvious conformation problems tend to bring lower prices at public auction. Over the years, various studies of conformation faults and racing performance have produced contradictory results.

- Signs can be seen as early as 5 months of age, but may not occur until the horse is started into work. Lameness varies with location and severity of the OCD; most horses are sound at a walk but may display lameness at faster speeds or when put into work.OCDs can occur in virtually all joints, but they occur most frequently in the hock, stifle and fetlock joints.verview: Osteochondritis dissecans (OCD) is a relatively common developmental disease that affects the cartilage and bone in the joints of horses. It causes clinical signs of disease in 5-25% of all horses and can occur in all horse breeds.

For example, March of Dimes grantees have discovered genes that contribute to heart defects and to cleft lip/palate, both of which are among the most common birth defects.

The average miniature horse mare will carry her foal for around 330 days before giving birth. The actual length of pregnancy can vary between 320 days and 380 days.very mare is different, so if you're not sure exactly how long your mare normally carries her foals, you should start watching her for signs of delivery when she's about 300 days from her most recent breeding.

Equine Founder - Causes and Treatment Causes of Equine Laminitis. Laminitis in horses can be caused by a number of things, the most common being grain overload, followed closely by the ingestion of too much green grass and sudden feed changes. Other causes are the horse being ridden too hard, especially in an over weight or out of condition horse.

- Laminitis is a disease that causes lameness in horses. It was once associated primarily with overweight ponies, but it can affect any age or size of horse. 1  With this disease, the laminae weaken, which attach the pedal bone to the inside of the hoof. 2  The horses pedal bone detaches from the inside of the hoof. The horses pedal bone detaches from the inside of the hoof. 2  Therefore, the pedal bone can turn, and sometimes, it even pushes through the sole. 3  When it pushes through the sole, it's called founder.. 4  This bond is composed of a non-living layer and a sensitive living layer, much like nails and the nail beds.

Horse breeding Humans can increase the chances of conception, a successful pregnancy, and successful foaling. The male parent of a horse, a stallion, is commonly known as the sire and the female parent, the mare, is called the dam. Both are genetically important, as each parent provides 50% of the genetic makeup of the ensuing offspring, called a foal.

- A cataract is a dense opacity of the lens. Horses may be born with cataracts (congenital cataracts) or cataracts may develop after birth in the foal (juvenile cataracts) or the adult horse (adult or senile cataracts).hile cataracts may be inherited, this is not overly common in the horse. Cataracts may also be caused by an injury to the eye, but most cataracts in adult horses are caused by diseases that lead to inflammation within the eye.
