Lambs typically get clinical coccidiosis between 4 and 8 weeks of age, especially in contaminated environments, though infection starts earlier as they ingest oocysts from their mothers or contaminated feed/water. Younger lambs (under 3 months) are most at risk, but older lambs can show poor performance or chronic issues, with immunity usually developing around 12 weeks.
Coccidiosis is caused by single celled parasites (protozoa) called Eimeria, which undergo a simple life cycle in the gut. Coccidiosis is most common in young lambs aged between 2 – 8 weeks, peaking at 5-6 weeks of age when they start to eat grass.
Coccidiosis is a parasitic disease that can occur in calves from as young as 4 weeks of age, but normally between 3-8 months. Infection is by ingestion of coccidia oocysts, from contaminated pasture, feed, water or grooming each other.
Lambs four to six week-old are most commonly affected. The common presenting signs are a rapid loss of weight and foetid diarrhoea containing mucus and flecks of blood, causing staining of the perineum and tail. Straining, with partial eversion of the rectum, is often accompanied by painful vocalisation.
Coccidiosis is a gastrointestinal illness caused by a protozoan. Clinical signs include diarrhea (with or without mucus), hematochezia, lethargy, weight loss, vomiting, signs of abdominal pain, pallor, and anorexia.
Bloody Poop
If blood is found in a chickens feces, this can be an indication that a chicken has coccidiosis. This is a serious intestinal infection that can spread to your entire flock, and can unfortunately result in death if not attended to properly (and can result in death if not attended to properly).
As with any disease, prevention is the best cure for coccidiosis. Coccidiosis in lambs and kids can be prevented by using sanitary feeding conditions (whether feeding dams or offspring), including clean, manure-free feed troughs for supplements and not feeding supplements on the ground.
Diclazuril and toltrazuril are oral drenches which can be used for treatment in the face of an outbreak. They should be given to all lambs over three weeks of age in a group where coccidiosis has been diagnosed as the cause of clinical disease. It may be necessary to repeat the diclazuril dose after three weeks.
Several articles and opinions exist on how to treat chickens with coccidiosis naturally. Many people recommend apple cider vinegar, garlic, oregano, and other herbs and oils. I prefer to give my flock Chicken E-lixir™. Chicken E-lixir is a supplement I give to my chickens that's like a daily vitamin.
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.
Coccidia lives on the vitamin thiamine (b1); and CORID strips all vitamins, therefore killing the Coccidia. That's why we recommend only giving CORID water and feed during treatment days — and liquid vitamins after treatment days.
Animals infected with coccidia pass parasite eggs in their faeces. These eggs can survive for up to two years in moist environments such as soil and calf sheds, which means that infection can be carried over from one season to the next. However, the eggs are destroyed by drying and heat.
Coccidia is contagious between dogs. Fortunately, the protozoa are host-specific, so while cats can become infected with certain subspecies of Isospora, your dog cannot pass the disease to cats in the household. Similarly, the disease is not contagious for humans.
An infection with coccidia does not always mean an illness is present. Many cats will eliminate the parasite on their own while others may shed oocysts in their stool without ever showing symptoms (asymptomatic).
Scouring (diarrhoea) is watery poop that can be serious if left untreated. Scouring is often caused when new milk is introduced so bottle lambs are prone to it in the beginning. It can also be a sign of infection. It is very important to keep your lamb hydrated during a scouring episode.
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.
Prevention
To begin with, there is no effective, safe chemical to apply to the soil to kill the coccidia cysts. Over time, the cysts die from the drying and rays of the sun. Preventive measures are focused on sanitation by reducing manure and providing clean, dry environment.
Diagnosis and Treatment
If you suspect your pet may have coccidiosis, it is important to seek veterinary care promptly. At Mission Veterinary Clinic, our experienced team will perform a thorough examination and may conduct a fecal test to identify the presence of coccidia.
Coccidiosis is a disease of young lambs, usually from 3-8 weeks of age. New-born lambs have passive immunity transferred in colostrum. Lambs become susceptible at 2-3 weeks of age and remain susceptible until immunity develops at approximately 8 weeks of age.
Common signs in infected flocks include:
Garlic is a natural antibiotic
I have also used it for sheep with upper respiratory infections that I've been able to catch in the early stages. (I've often used fresh garlic on myself in the early stages of a cold too -- and does it ever work!)
It has been shown diclazuril appears to have a direct effect on several stages of the parasite's life cycle (in particular, the large, first-generation meronts) and that maximum benefits can be obtained if treatment is provided early in the infection – before damage to the intestine occurs.
If added to sheep and lamb drinking water apple cider vinegar will assist in keeping waterers free of algae and mosquito larvae. Improves the quality and yield of wool. Reduces the incidence of urinary calculi and kidney stones. It has powerful healing, cleansing, and natural antibiotic and antiseptic qualities.
How do sheep become infected with coccidiosis? Contaminated water and feed troughs, and the skin of dams' udders are common routes for the spread of coccidiosis and infection is by the faecal-oral route: once oocysts (eggs) are passed out they can be eaten by the same or new animal.
