The Inside Story - For as long as horses have been grazing the hillsides and meadows, the pest of parasite infestation has plagued them. Perennial as the grass, intestinal parasites find every possible opportunity to enter their horse host, and live out their life cycle.

Flexural limb deformity occurs in two forms. The first form, also known as contracted tendons, clubfoot, or knuckling, is the inability to extend a limb fully. The condition may be present at birth (congenital) due to improper positioning in the uterus (which can lead to dystocia in the mare), abnormal fetal development, disease or malnutrition in the dam; or acquired as the result of nutrition (abrupt changes in amount or quality of feed leading to rapid growth), polyarthritis, trauma, or disease. It is a common condition in foals, usually occurring anytime from birth to 14 months of age.

A common cause of diarrhea in foals less than six months old. Equine rotavirus damages the lining of the intestines, inhibiting digestion and absorption of food. It is one of the most common causes of diarrhea in foals less than six months of age. Foals become infected when they ingest materials or lick surfaces contaminated with infected feces.

A recent study has concluded that standing flank laparotomy may be a suitable option for surgical treatment of some cases of equine colic. The standard surgical approach for colic is through an incision in the ventral midline, with the horse under general anaesthesia. General anaesthesia poses additional risks over and above those of the surgery itself, and the personnel and equipment required increase the cost.
