TL;DR: Sheep and goats are small ruminants that are very good at hiding illness, so problems are often caught late. In Indonesia's humid climate, gastrointestinal worms (especially the blood-sucking barber pole worm) are the number one threat and can cause anemia and even death. Other common problems include bloat, enterotoxemia from sudden feed changes, footrot and overgrown hooves, coccidiosis in the young, pneumonia, orf, and urinary stones in males. The keys to prevention are simple: a stable forage-based diet, dry and well-ventilated housing, regular hoof care, a vet-guided deworming and vaccination program, quarantine for new animals, and daily observation. Remember that sheep are far more sensitive to copper than goats, so their minerals must not be treated as interchangeable. Call a vet promptly if an animal stops eating, is severely bloated, strains but cannot urinate, has pale gums, is badly lame, or if there is sudden death. An initial consultation with our team on WhatsApp is free.
Keeping sheep or goats looks simple from the outside: just give them grass and water. But the moment one becomes lethargic, refuses to eat, or suddenly dies for no obvious reason, many new owners realize how much they did not know. The good news is that most sheep and goat health problems can be prevented or caught early, as long as you know what to look for. Let us walk through it calmly, from the basics of care to when you need to call a vet.

Why sheep and goats need a different approach
Sheep and goats are both ruminants, meaning their stomach is divided into compartments and their digestion relies on microbes in the rumen. Because of this, sudden feed changes can disrupt the microbial balance and trigger serious problems. Good feed changes are always made gradually over several days, never all at once.
Although they are often lumped together, the two have different feeding habits. Goats are browsers that naturally prefer to pick leaves, twigs, and taller plants. Sheep are grazers that prefer to eat grass close to the ground. This difference affects how they are exposed to parasites and certain plants.
One crucial difference: copper sensitivity
This is often overlooked and dangerous. Sheep are far more sensitive to copper than goats. Feed, minerals, or premixes formulated for goats, cattle, or other livestock that contain added copper can build up and poison sheep. So do not simply treat commercial minerals and feed as interchangeable between sheep and goats. If you keep both together, separating feed and choosing the right minerals should be discussed with a vet.
The basics of correct care
Most of a sheep's or goat's health comes down to simple things done consistently every day:
- A forage- and fibre-based diet. The foundation is quality fresh grass, forage, or hay, available in sufficient amounts. Concentrates or grains are only supplements in reasonable portions, not the main meal. A sudden excess of concentrate is a classic trigger for bloat and enterotoxemia.
- Clean water available at all times. Dirty or empty water reduces feed intake and increases the risk of digestive problems and urinary stones.
- Minerals and salt suited to the species. Small ruminants need balanced minerals, but remember the copper point above: the right mineral for sheep and goats is not always the same.
- Dry, well-ventilated housing. Wet, muddy floors are a source of footrot, worms, and respiratory disease. Provide shelter from rain and wind, dry bedding, and enough air flow so ammonia from droppings and urine does not build up.
- Regular hoof care. Overgrown hooves make animals lame, trap dirt, and invite footrot. Periodic hoof trimming is important preventive care.
- Daily observation. Each day, watch whether the animal eats eagerly, whether it is chewing cud (rumination) normally, the shape and consistency of its droppings, whether it moves actively, and whether its breathing is calm. Small changes caught early are far easier to manage.
- Quarantine new animals. Newly arrived animals should be kept separate for a while before joining the group, to make sure they do not bring disease or parasites to the existing flock or herd.
Common diseases: causes and signs to recognise
Gastrointestinal worms (the main threat in the tropics)
In a warm, humid environment like Indonesia, gastrointestinal worms are one of the most frequent causes of death in sheep and goats, but also one of the most manageable. One of the most dangerous is the blood-sucking barber pole worm, which causes anemia. Signs include:
- Pale inner eyelids and gums (instead of a healthy pink)
- Soft swelling under the jaw, known as bottle jaw
- Weakness, low energy, and weight loss
- A dull coat, sometimes with diarrhoea, and stunted growth in the young
Periodically checking the colour of the inner eyelid (a scoring method known as FAMACHA) helps you and the vet decide which animals truly need deworming, so treatment is more targeted and drug resistance can be reduced.
Coccidiosis
This protozoal parasite disease most often affects lambs and kids, especially under high stocking density and in dirty pens. Signs include diarrhoea (sometimes bloody or mucoid), straining, weakness, reduced appetite, and stunted growth. Clean housing and reasonable stocking density are the keys to prevention.
Bloat (ruminal tympany)
Bloat happens when gas builds up in the rumen and cannot escape. It is often triggered by wet young legumes, sudden feed changes, or excess concentrate. The signs are distinctive: the left side of the abdomen becomes enlarged and tight, the animal is restless, short of breath, and reluctant to move. Severe bloat is an emergency that can kill quickly.
Enterotoxemia (overeating disease)
This condition is triggered by clostridial bacteria that multiply rapidly when there is a surge of starch-rich feed, for example when an animal suddenly gets a lot of concentrate or grain. Often it is the healthiest, greediest animals that are affected. Signs can appear very fast: sudden death, seizures, diarrhoea, or apparent severe pain. Because it progresses so quickly, prevention through vaccination and feed management is far more effective than treatment after signs appear.
Pneumonia and respiratory problems
Respiratory disease is fairly common, especially with changing weather, poor ventilation, dusty pens, or stressed animals. Signs include coughing, nasal discharge, rapid or noisy breathing, fever, lethargy, and reduced appetite. This can worsen quickly and should be seen by a vet.
Footrot and hoof problems
A muddy environment softens hooves and makes them prone to infection. Footrot causes lameness, foul-smelling hooves, and a reluctance to stand or walk. Long, neglected hooves make it worse. Keeping floors dry and trimming hooves regularly is the best prevention.
Orf (contagious ecthyma)
Orf causes scabby sores around the lips, mouth, and sometimes the udder. It spreads between animals, and importantly, orf is zoonotic, meaning it can spread to humans through direct contact. Always wear gloves and wash your hands when handling affected animals.
Caseous lymphadenitis (abscesses)
This chronic disease is marked by pus-filled lumps in the region of the lymph nodes, such as around the neck or under the jaw. It spreads within the group and is hard to eliminate completely, so managing and preventing its spread needs vet guidance.
Urinary stones in males
Urinary stones (urolithiasis) are more often a serious problem in males, especially castrated ones fed high concentrate with a poor mineral balance. Signs include straining to urinate, dribbling or no urine at all, restlessness, painful vocalising, and an enlarged abdomen. This is an emergency that must not be delayed.
Mastitis in nursing females
Inflammation of the udder in a nursing female makes the udder swollen, hot, hard, or painful, and the milk becomes abnormal (clumpy, bloody, or watery). Besides being painful for the mother, mastitis also endangers the nursing offspring.
External parasites
Lice, mange mites, and ticks cause itching, hair loss, crusting, and restlessness. Beyond the discomfort, some external parasites also lower body condition and can transmit disease.
Diseases that must be watched for and reported
Some livestock diseases are highly contagious or dangerous to humans, so managing them involves animal health authorities:
- Foot and Mouth Disease (FMD). This highly contagious disease of cloven-hoofed animals causes sores or blisters in the mouth and around the hooves, excessive drooling, lameness, and refusal to eat. If you suspect it, contact a vet immediately and report it to your local animal health officials.
- Anthrax. This disease can cause sudden death and is zoonotic (transmissible to humans). If an animal dies suddenly for no clear reason, do not slaughter, open, or consume the carcass. Report it promptly to a vet or animal health officer for safe handling.
What you can do at home to prevent problems
Prevention in sheep and goats rests mostly on daily management, not medicine. Here are steps you can take:
- Quarantine every new animal before joining it to the existing group, to keep out disease and parasites.
- Manage parasites in a targeted way, not blindly on a schedule. Deworming indiscriminately actually speeds up resistance. Combine monitoring (such as checking eyelid colour), pasture management or rotation, and deworming as advised by a vet so treatment hits the right animals.
- Follow a vaccination program as advised by a vet. Vaccines against clostridial diseases (such as enterotoxemia and tetanus) are commonly recommended for sheep and goats. The type, timing, and boosters are best arranged with your vet.
- Trim hooves periodically and keep floors dry to prevent footrot and lameness.
- Give colostrum to newborns. Young that get enough colostrum in the first hours of life are far more resistant to disease.
- Change feed gradually and avoid concentrate surges to prevent bloat and enterotoxemia.
- Choose species-appropriate minerals and keep the sheep copper sensitivity in mind.
- Record and monitor body condition and weight. A drop in body condition is often the earliest alarm, before other signs appear.
- Maintain hygiene and biosecurity, including washing your hands after handling animals, since some diseases can spread to humans.
When you need to call a vet
Many things can be managed at home, but some situations should not be delayed. Seek a vet's help promptly if you see:
- An animal that stops eating or stops chewing cud, is weak, or isolates itself from the group.
- The left side of the abdomen swelling rapidly with the animal short of breath. This can signal dangerous bloat.
- A male straining but unable to urinate, or only dribbling urine. This is a urinary stone emergency.
- Pale eyelids or gums, swelling under the jaw, or other signs of anemia.
- Severe lameness, foul-smelling hooves, or reluctance to stand.
- Persistent diarrhoea, especially in the young, or bloody diarrhoea.
- Rapid breathing, coughing, nasal discharge, or fever.
- Difficult birthing that does not progress within a reasonable time.
- Scabby mouth sores, excessive drooling, or other suspicious signs pointing to a contagious disease.
- Sudden death in one or more animals. Do not open the carcass yourself; contact a vet or animal health officer.
We can help by examining them right in your pen
Handling sick sheep and goats is often calmer when the vet comes directly to the location, because the animals do not have to endure the stress of travel and the vet can also assess the housing, feed, and the whole group at once. You can request a home visit vet for sheep and goats to check the animals, assess the risk of worms and anemia, and set up a prevention program suited to your pen.
Not sure whether your animal needs urgent attention or can be monitored for now? You can start with a free online consultation first. Tell us the signs, the number of animals, the feeding routine, and your area, then reach a Prabasa vet on WhatsApp. Our team will help assess whether it can be handled in the pen or needs further steps, and schedule a visit if needed. For serious cases or a suspected contagious disease, we will be honest and recommend the right course of action, including involving animal health authorities when needed, for the safety of your animals and your family.
FAQ
Can goat medicine be given to sheep, and vice versa?
Not always safely. The most important difference is copper: sheep are far more sensitive to copper than goats, so a mineral or product that is safe for goats can be dangerous for sheep. Doses and product choices also differ by species, weight, and the animal's condition. So follow your vet's advice and do not simply treat the two species as interchangeable.
What vaccines are commonly recommended for sheep and goats?
Vaccines against clostridial diseases (such as enterotoxemia and tetanus) are commonly recommended for small ruminants. The right type, schedule, and boosters depend on your housing, the animals' ages, and pregnancy status, so they are best arranged with a vet rather than decided on your own.
Can sheep and goat diseases spread to humans?
Some can. For example, orf (scabby mouth sores) and anthrax are zoonotic. So make a habit of wearing gloves when handling sick animals, washing your hands afterwards, and never slaughtering or opening the carcass of an animal that died suddenly. When in doubt, consult a vet.
Does Prabasavet handle sheep and goats?
When you contact us on WhatsApp, mention the type of animal, how many, the signs you see, and your area. Our team will help point you to a suitable partner vet for small ruminant livestock.
Wrapping up
Sheep and goats are relatively hardy animals, but that is exactly why they are so good at hiding illness until things are fairly advanced. With a stable diet, dry and well-ventilated housing, regular hoof care, a targeted deworming and vaccination program, and the habit of observing them daily, most common diseases can be prevented or caught early. When you are unsure about an animal's condition, an earlier consultation is always better than waiting.
Notes & references
This article is general and educational, drawing on the principles of small ruminant livestock medicine, and does not replace a direct exam by a vet handling your case. The choice of dewormers, vaccines, minerals, and other products, including doses and suitability for sheep, goats, young animals, or pregnant animals, must follow a vet's advice, because some substances that are safe for one species can be dangerous for another (notably sheep sensitivity to copper). Conditions such as severe bloat, enterotoxemia, urinary stones, Foot and Mouth Disease, and anthrax can be life-threatening and some are zoonotic, so they require prompt medical care and, where necessary, the involvement of animal health authorities.
