Bottle Jaw in Sheep & Goat: Causes, Signs, and What to Do

Bottle jaw is a soft, fluid-filled swelling beneath the lower jaw of sheep and goats caused by oedema. It is often associated with liver fluke infection and other conditions that cause low blood protein, leading to fluid accumulation, poor body condition, chronic scour, and weakness. Bottle jaw most often caused by parasites such as liver fluke (Fasciola hepatica) or barber’s pole worm (Haemonchus contortus). This Parasites like fluke (Fasciola hepatica) effect the liver which reduce the production of important blood protein. while barber’s pole worm feeds on blood in the stomach, causing severe anemia. Both lead to a drop in albumin (a key blood protein), allowing fluid to leak into tissues under the jaw.

The condition can appear suddenly, especially during warm and wet seasons when parasite activity is high. Affected animals often show signs such as swelling under the jaw, pale eyes and gums, weakness, weight loss, and in severe cases, sudden death. Bottle jaw is a warning sign of serious internal problems and should never be ignored. You can find parasites with faecal tests or blood tests. Your veterinarian will tell you how to deworm your animals. Getting treatment early stops parasites from hurting more animals in your flock or herd.

Animal’s Farming is a platform that provides information about various animal diseases, including their causes, symptoms, treatment, and prevention. Let’s dive into bottle jaw disease in goats and sheep.

Symptoms of Bottle Jaw in Goats and Sheep

The most noticeable sign of bottle jaw is a soft, cool, and fluid-filled swelling under the lower jaw, also known as submandibular edema. The swelling may feel squishy or pitting when pressed, and in severe cases, it can extend down toward the throat area. This swelling often appears more prominent later in the day when the animal has been grazing with its head down, as gravity causes fluid to pool in the loose tissues beneath the jaw. In the early morning, the swelling may temporarily appear reduced, giving a false impression of improvement.

Along with swelling, animals suffering from bottle jaw typically show signs of anemia and general weakness. Their gums and inner eyelids become pale to white, which can be quickly assessed using the FAMACHA scoring system. Affected goats and sheep may become lethargic, tire easily, and show reduced interest in feed. Weight loss, poor body condition, and rough or dull hair coats are common as the animal’s body struggles to absorb nutrients properly due to internal parasitic damage.

Cause for Bottle Jaw in Goats and Sheep

Parasites such as liver fluke (Fasciola hepatica) or barber’s pole worm (Haemonchus contortus) are main cause of bottle jaw. Bottle jaw in goats is severe anemia resulting from heavy infestations of barber’s pole worms (Haemonchus contortus) — a type of blood-sucking internal parasite. These worms live in the abomasum, which is the goat’s true stomach, and attach themselves to the lining using small teeth. They pierce the stomach wall, creating tiny wounds that bleed, and feed directly on the goat’s blood. While a small number of worms may not cause noticeable harm, a large infestation can lead to significant blood loss over time, resulting in severe anemia and low blood protein levels.

As the goat’s red blood cells and proteins (especially albumin) are depleted, the blood can no longer hold fluid properly within the vessels. This causes fluid to leak out and accumulate in the loose tissue under the lower jaw, forming the characteristic swelling known as bottle jaw. If worms keep feeding, your goat loses blood faster than it can make new blood cells. This makes the goat weak and pale around the eyes. Without treatment, the goat can die.

It’s also important to note that barber’s pole worm infestations usually do not cause diarrhea. If your goat shows both bottle jaw and diarrhea, the cause may be another internal parasite, such as liver fluke or a digestive infection. Environmental conditions like warm, wet weather and overgrazed pastures can increase the risk of infection, as they allow worm larvae to thrive and spread easily among grazing goats.

Treatment of Bottle Jaw in Goat and Sheep

The primary treatment of bottle jaw involves the execution of internal parasites, including liver fluke. It uses effective anthelmintics such as macrocyclic lactones and specific flukicides like triclabendazole.

If bottle jaw is suspected in goats or sheep, immediate veterinary consultation is essential to identify and address the cause.

Your veterinarian might suggest protein-rich feed or special additives if your animal lacks protein or nutrients. These supplements help the animal recover.

In severe cases, fluids and electrolytes may be administered intravenously to stabilize the animal.

It is important to note that Johne’s disease is untreatable, while lymph node abscesses are generally best left untreated. If the cause is related to salivary gland blockage, treatment may include gentle massage and the removal of grass seeds or other obstructions from the salivary duct openings under the tongue or inside the cheek.

Supplements Used in Bottle Jaw

When you recognize that your sheep is not feeling well and also shows symptoms of bottle jaw, at an early stage you can use supplements to prevent your goat or sheep from becoming weak, or you can also start supplements afterward to help the animal recover faster. As bottle jaw decreases the number of red blood cells in the animal, vitamin B12 is a must for the animal. There are a few more; let’s discuss each one separately.

Vitamin B12 Supplements for Goat and Sheep in Bottle Jaw Disease

Vitamin B12 is a supportive supplement that increases the production of red blood cells, which fight anemia, one of the common symptoms of bottle jaw in goats and sheep. It also supports the animal’s energy recovery, weight gain, and appetite.

• Kaeco Vitamin ADE B12 Oral Gel is one of the best B12 vitamin supplements for goats and sheep.
• Rooster Booster B-12 Sheep and Goat Liquid, 32-Ounce, is also good for vitamin B12.
• Growel Agrovet Growvit Power Multivitamin: Here you will get some other beneficial vitamins for the animal too. In Growel Agrovet, you will get Vitamin A: 120,000 IU, Vitamin D3: 60,000 IU, Vitamin E: 500 mg, Vitamin B12: 200 mcg, Selenium: 100 ppm, Biotin: 0.50 mg, Lysine: 100 mg, Choline: 100 mg, Methionine: 100 mg.

Electrolytes

Electrolytes help animals to rehydrate and support the animal’s system, especially if they are not drinking well. Here are a few of the best electrolytes for goats and sheep.

Prevention of Bottle Jaw in Goat and Sheep

Parasites are the main cause of bottle jaw in goats and sheep. Prevention of bottle jaw is possible by managing parasites, providing a clean and healthy diet, and maintaining hygiene. The best way to protect your herd from bottle jaw is deworming, providing enough nutrition, and also separating new animals to prevent the spread of this in the herd.

Conclusion of Bottle Jaw Disease in Goat and Sheep

Bottle jaw in goats and sheep is not a disease itself but a serious symptom of underlying health issues, most commonly caused by internal parasites such as liver flukes and barber’s pole worms. These parasites lead to anemia and loss of blood proteins, resulting in the characteristic swelling under the jaw.

Early detection and prompt veterinary intervention are crucial for successful treatment. Regular deworming, maintaining proper nutrition, and ensuring clean, parasite-free pastures are the best preventive measures. Supportive care with vitamin B12, electrolytes, and protein-rich supplements can help affected animals recover faster.

Feed your herd well and check their health often. Use deworming regularly. This stops bottle jaw and keeps your goats and sheep healthy and productive.
