In other posts I have touched on respiratory conditions and drug use but have not went after it specifically. If you think OPP is a factor then review my articles on that subject, but it is not an economic factor in commercial sheep production. That being said let’s go to the heart of the situation. Early diagnosis and prolonged treatment are essential for successful treatment. Delayed diagnosis results in extended treatment and permanent lung damage. Discontinued treatment to soon results in re-occurrence and permanent lung damage as well.

What is my suggestion? Simultaneous injections of Nuflor and Draxxin subcutaneously immediately and repeat the Nuflor in 48 hours. Nuflor should be used at the rate of six cc per 100 pounds and Draxxin at one cc per 88 pounds of body weight. Give five cc of Biomycin per 100 pounds subcutaneously (may be substituted for Nuflor). Draxxin is expensive and may not always be necessary but has a different mode of action and lasts up to five days.

For coughing sheep, use sulfas in drinking water for three to five days may be helpful. Clinically sick animals need to be individually treated.

There is a Pasteurella bacterin available for vaccination, which I don’t believe to be effective. The intranasal cattle vaccine is ineffective in sheep.

About Ask-a-Vet Sheep

Veterinary services, procedures, biologicals, and drugs mentioned in this publication represent the personal opinions and clinical observations of the contributing author. They are in no way intended to be interpreted as recommendations without the consent of the producer’s own practicing Veterinarian. We strongly urge that producers establish a patient-client-veterinarian relationship that allows extra-label use when there are no drugs approved for treatment or if approved drugs are not effective. This procedure allows veterinarians to go beyond label directions when “prudent use” is necessary. The limited availability of drugs and biologics in this country is a major factor in restricting the growth of the sheep industry and allowing producers to compete in the world market place.
