What Is Scouring In Sheep? In livestock, diarrhea is called scours. There can be many causes of diarrhea: bacterial, viral, parasites, and diet. Flystrike risk. Sheep that have diarrhea are more prone to flystrike (blowflies or maggots). To help prevent flystrike, it is recommended that lambs be docked.
What causes scouring in sheep? There are numerous causes of scouring in sheep, including bacterial and other infections, plant toxicities and some mineral imbalances, but the overwhelming causes relate to worm infection.
What does scours in lambs look like? Lamb Scours
Nutritional scourers is identified by white or yellow sticky runny faeces. Infectious scours are more common in young lambs. Faeces can be watery and brown or yellow. Lambs will become very dehydrated which can lead to sunken eyes.
How do you treat diarrhea in sheep at home? If you cannot get veterinary help you can give the animal a home treatment of rehydration fluid. To make rehydration fluid mix six teaspoons of sugar and half a teaspoon of salt with 1 litre of clean, warm water. Give this as a drench (500 ml for sheep or goats) four times a day for 3 days.
What causes coccidiosis in sheep? Coccidiosis is caused by parasitic protozoa in the genus Eimeria. The Eimeria are host-specific and those that infect cattle will not infect sheep or goats. The life cycle of coccidia is complex with its reproduction occurring in the animal’s intestinal cells.
Whatever the microbial cause of scours, the most effective treatment for a scouring lamb or kid is re-hydration by administering fluids. The most common causes of diarrhea in older lambs and kids are coccidiosis and gastro-intestinal parasites (worms).
Aureomycin is the only antibiotic currently approved for use in the feed for sheep.
They have a watery, whitish-yellow or greyish diarrhoea that is known as “white scours”. The umbilical cord is sometimes red and swollen. The back legs are dirty with droppings. Lambs/kids usually die as a result of dehydration.
Symptoms. Lambs with coccidiosis present with diarrhoea (sometimes showing blood), high temperature, poor appetite, weight loss, anaemia and sometimes, death. The coccidial oocysts are readily identified in faecal samples.
Sulfaquinoxaline in drinking water at 0.015% concentration for 3–5 days may be used to treat affected lambs. In groups of lambs at pasture, frequent rotation of pastures for parasite control also helps control coccidial infection.
Recommended treatments for calf scours:
The highest priority in treating scours is to give back to the calf the water and electrolytes that it has lost in scours – this is called fluid therapy. This corrects dehydration, restores normal acid-base balance, and replaces salts in the calf’s bodily fluids.
Treatments include intravenous fluids, drenching with bicarbonate solution or milk of magnesia, intraruminal antibiotic injections, thiamine or steroid injections, and surgery for very valuable animals.
There are two other medications that can be used to control coccidiosis in sheep and goats; however their ability in the US is limited: Baycox® (Toltrazuril) and Vecoxan® (diclazuril).
The most popular treatment for coccidiosis is Amprolium, which blocks the parasite’s ability to uptake and multiply. Treatment is usually administered by adding Amprolium to the chickens’ water supply, however in some cases, where sick chickens aren’t eating or drinking enough, the medication is given orally.
In some kittens or adult cats, coccidiosis may spontaneously go away on its own. In severe cases, both symptomatic and causative treatments may be needed. A course of antibiotics such as Sulfadimethoxine, Trimethoprim-Sulfonamide or Amprolium can stop the coccidia from reproducing.
People also need to be aware that orf virus can also live on wool, fencing and hedges.” Ringworm is occasionally seen in sheep and infected stock should be treated. However, the fungus can enter the human body through wounds. “Infections can even occur around shirt cuffs, where they rub on arms,” says Mr Davis.
Rehydion gel can be fed with milk or, in animals that are up and about with a good suckle reflex, administered neat using a pump. In early cases, this is often enough to counteract the initial effects of scour and associated electrolyte imbalances.
DEXAMETHASONE INJECTION 2 mg/mL is indicated for the treatment of acute musculoskeletal inflammations, such as bursitis, carpitis, osselets, tendonitis, myositis, and sprains.
Affected sheep can be drenched with 15g of baking soda (sodium bicarbonate) in 600ml of water. Repeat if necessary. Losses can occur when sheep are given high protein feeds after a period of fasting or after moving from dry pastures to rapidly growing crops.
If pasture is limited and you can’t move onto rested areas then it’s important that lambs are wormed every three or four weeks from six weeks of age.
It is also approved by the World Health Organisation as a food additive and has the e-number E234. Tests have so far shown that nisin J is effective against a range of harmful gram-positive bacteria including MRSA and Cutibacterium acnes, which causes acne.
“But overfeeding is the biggest issue once a lamb is on milk replacer, and it too can produce scours.” This is because milk should be processed in the sheep’s fourth stomach, and overfeeding can spill milk into the rumen, where it ferments, so the lamb gets gassy and the stomach becomes extended.
Coccidiosis is a problem of intensively-reared lambs, occurring primarily indoors where stocking densities are high but may also occur in lambs at pasture, where there is heavy contamination around feed troughs in creep areas during warm wet weather. Loss of gut absorptive capacity results in profuse diarrhoea.
While you can technically wean a healthy lamb at 6 weeks of age, we suggest weaning at around 10-12 weeks of age. Before you start to wean your lamb, they should be at least 3 times their birth weight (no less than 10kg), and be eating and drinking water themselves.
Several oral medications may be used to treat coccidiosis. Most pets will require daily treatment for 5 to 10 days, but some pets will have to be retreated if the infection isn’t resolved after the first or even second go-round.
