  • When aluminum-precipitated toxoids or bacterins are used, the injection should be administered at such a site that the local cold abscesses, which commonly develop, can be removed easily during normal dressing and will not blemish the carcass.

  • It is characterized by sudden death that occurs approximately 12 hours after the first signs of the disease appear. Should the animal die, a necropsy can be performed to look for evidence of disease.

  • When purchasing lambs from a breeder or through a club lamb sale, it is a very good idea to ask the breeder if the lambs have been vaccinated.

  • Deaths are also uncommon in lambs born to ewes vaccinated during late pregnancy see Figure 1 and Protection Strategies and fed a high-energy creep diet since early life.

Goats can be found dead. Death gooats occur in a few hours, but less severely affected lambs may survive for a few days, and recovery is possible. Smears of intestinal contents can be examined for large numbers of gram-positive, rod-shaped bacteria, and filtrates can be made for detection of toxin and subsequent identification by neutralization with specific antisera. As you can see, the vaccinated ewes developed a rapid antibody response that declined over time and, more importantly, their lambs also received a huge dose of antibody at birth after consuming colostrum. Follow vaccine label instructions for dosage and timing as they differ slightly between manufacturers. Usually, the bacteria proliferate causing the toxin to be released within a short period.

Antibody levels in lambs from vaccinated moms declined over time of course, but the authors surmised that lambs were adequately protected for up to 12 weeks disease age. Contact your local county Extension office through our County Office List. This may explain why only a handful of unvaccinated adult sheep may die from enterotoxemia when a flock of ewes gets loose and finds a pile of grain. This posture is caused by the effects of the toxins on the brain.

  • Death commonly occurs within minutes to hours after this sign is seen.

  • Extension programs are available to all without discrimination.

  • Home Health. Smears of intestinal contents can be examined for large numbers of gram-positive, rod-shaped bacteria, and filtrates can be made for detection of toxin and subsequent identification by neutralization with specific antisera.

  • Providing trusted, practical education to help you solve problems, develop skills and build a better future. Tetanus protection is particularly important in lambs docked outdoors in pasture birth programs, as they are more prone to infection from this largely soil-born organism.

What Vaccine Should Be Used? My recommendation is days, as most booster immunizations will elicit a fast antibody response. Get the best thinking of the most accomplished group of Ph. Make sure the vaccine has been refrigerated, stored properly, and is not expired. Dosage: read and follow label directions as timing and dosage differ slightly between manufacturers.

Merck Veterinary Manual. On necropsy examination, a large section of the small intestine can appear dark red to purple Figure 1. A form of enterotoxemia caused by type B or type C C. Typically, it affects young lambs under two weeks of age or the weaned lambs that are consuming a high-carbohydrate diet grain. Smears of intestinal contents can be examined for large numbers of gram-positive, rod-shaped bacteria, and filtrates can be made for detection of toxin and subsequent identification by neutralization with specific antisera. In young lambs, the disease usually is restricted to ewes with single lambs, because ewes with twins seldom give enough milk to allow enterotoxemia to develop.

A product labeled for goats is recommended. Figure 1. Goat enterotoxemia. Types B and C both produce the highly necrotizing and lethal beta toxin responsible for severe intestinal damage. Follow vaccine label instructions for dosage and timing as they differ slightly between manufacturers.
