Five common diseases in sheep include Footrot, a contagious hoof infection; Flystrike, where flies infest wounds or wool; Internal Parasites (like Barber's Pole Worm); Ovine Johne's Disease (OJD), a chronic gut infection; and Clostridial Diseases (like Enterotoxaemia/Pulpy Kidney), often fatal sudden illnesses, along with issues like Scabby Mouth, Pinkeye, and Pneumonia, affecting various parts of the sheep's body and leading to significant losses if untreated.
Diseases that affect sheep
Johne's disease (JD) is an incurable, infectious wasting disease of sheep that can result in significant economic losses on infected farms due to sheep deaths and lost production in meat, lambs and wool.
Scrapie. Scrapie is a fatal, degenerative disease that affects the central nervous system of sheep and goats. It is classified as a transmissible spongiform encephalopathy. Infected flocks typically experience significant production losses.
Two common causes of sudden death include clostridial infections and pasteurella diseases. Investigate any cases of sudden death with your vet promptly to reduce further losses.
Major predators for sheep and goats are coyotes and dogs, but for younger animals, foxes, bobcats, vultures, or even raccoons can be problems as well.
Twenty common diseases, covering chronic and infectious types, include Heart Disease, Cancer, Diabetes, Asthma, Arthritis, Hypertension, Stroke, Chronic Obstructive Pulmonary Disease (COPD), Alzheimer's, Depression, alongside infections like COVID-19, Influenza (Flu), Pneumonia, Strep Throat, UTIs, Common Cold, Chickenpox, Chlamydia, Gastroenteritis, and skin issues like Acne/Eczema, impacting millions globally with varied causes from lifestyle to viruses.
Bacteria can cause a range of infections and illnesses, for example:
Clinical Signs of Coccidiosis of Sheep
When lambs are all of a similar age, most may show clinical signs. Acute infections result in sudden onset diarrhea, anorexia, dullness, and abdominal pain. Dehydration may result and there is marked loss of weight and body condition. Fever is unusual.
Bluetongue virus affects cattle, goats, sheep, deer and camelids such as llamas and alpacas. It can cause ulcers or sores around the animal's mouth and face, difficulties swallowing and breathing, fever and lameness, foetal deformities and stillbirths.
"Big Three" Infectious Diseases: Tuberculosis, Malaria and HIV/AIDS.
Dementia is one of the most feared conditions among Australian health service consumers, second only to cancer.
Vaccinate all adult sheep annually with a 6in1, ewes should be vaccinated 4 weeks before lambing. marking between 2-8 weeks old with 6in1 + Vit B12 and Gudair. the first vaccine to boost immunity, lambs can be weaned at this time.
Scrapie is a fatal, degenerative disease affecting the central nervous system of sheep and goats. The name "scrapie" was derived from the characteristic scraping infected animals do to relieve itching.
Lambs may be affected in both forelimbs, both hind limbs and all four limbs, with no evidence of any swelling. If able to stand, affected lambs have a stiff, stilted gait and an arched back; they exhibit muscle trembles and weakness. Affected lambs lie on their chest then roll onto their side and die within a few days.
Common signs in infected flocks include:
Sulfadimethoxine (Albon) is the only FDA-approved medication for coccidia in the United States. A few other medications, such as ponazuril, are often used off-label to treat coccidia with success. Coinfections with other parasites are common and may require additional medications.
Sheep infected with footrot become progressively more lame and exhibit the following signs in progressive order: Inflamed, red and moist skin between the digits. A grey pasty scum between the digits. Lifting of skin-horn junction between digits.
There are four main types of disease: infectious diseases, deficiency diseases, hereditary diseases (including both genetic and non-genetic hereditary diseases), and physiological diseases. Diseases can also be classified in other ways, such as communicable versus non-communicable diseases.
A Brief Introduction to the Top 3
The top 3 bacterial infections are Strep Throat, Urinary Tract Infections (UTIs), and Bacterial Pneumonia.
Common Illnesses
Number of deaths for leading causes of death. Heart disease: 680,981. Cancer: 613,352. Accidents (unintentional injuries): 222,698. Stroke (cerebrovascular diseases): 162,639.
Germs that cause infectious diseases include viruses, bacteria, fungi, parasites and, rarely, prions. We all get infectious diseases. You can get them from breathing in germs (like after someone coughs or sneezes), from bug bites, from contaminated food and from the environment around you.
