Permanent Tracheostomy in Standing Horses

Diseases of the upper airway such as laryngeal hemiplegia, arytenoid chondritis, subepiglottic cysts, aryepiglottic fold entrapment, and dorsal displacement of the soft palate are commonly encountered in horses. In all of these conditions some abnormality of the upper airway compromises the cross-sectional area of the airway and causes decreased airflow; the condition usually becomes clinically… Read More »

Treatment of Vasculitis

Treatment of purpura hemorrhagica and similar idiopathic vasculitides consists of the following: (1) removing the antigenic stimulus; (2) suppressing the immune response; (3) reducing vessel wall inflammation; and (4) providing supportive care.

Many farm managers and horse owners with a veterinary client-patient relationship may be instructed to begin intramuscular (IM) injections of oxytocin 2 to 4 hours postpartum… Read More »

General Considerations For Testing Ability Of Spermatozoa To Survive Cooled Storage

Preservation of semen begins with the collection process. Accurate assessment of semen quality relies heavily on proper semen collection techniques. Ejaculated semen is susceptible to environmental influences. Therefore mishandling semen samples before evaluation can lead to erroneous interpretation of results, thereby negating their value for representing the ability of a stallion’s spermatozoa to survive the… Read More »

Twins

The diffuse microcotyledonary placentation of the mare makes it highly unlikely that a twin pregnancy will be carried to term. If the twin pregnancy is maintained until the latter part of gestation the placenta cannot meet the nutrient demands of the rapidly growing fetuses. Death of one or both fetuses is followed by abortion, with… Read More »
