Why Goats Get Sick More Often Than You Think
Goats have a reputation for being hardy, but experienced keepers know the truth: they are actually one of the more health-sensitive livestock species, prone to a specific set of diseases that can move quickly through a herd. Understanding the most common threats, building a vaccination calendar, and managing internal parasites proactively are the three pillars of goat health management.
Common Diseases in Goats
Clostridial Diseases
Enterotoxaemia (pulpy kidney) and tetanus are caused by Clostridium bacteria and rank among the most common killers in goat herds. Enterotoxaemia is triggered by sudden dietary change, particularly a rapid increase in grain. Animals may be found dead with no prior signs, or display neurological symptoms and bloat. Tetanus follows wounds, castration, or disbudding. Both are almost entirely preventable through vaccination.
Caseous Lymphadenitis (CLA)
Caused by Corynebacterium pseudotuberculosis, CLA presents as firm, painless abscesses around the lymph nodes of the neck, shoulder, or flank. The condition is highly contagious within a herd, spreads via pus from ruptured abscesses, and has no reliable cure once established. Biosecurity and culling of affected animals remain the primary control tools. Vaccines are available in some regions and should be discussed with your vet.
Caprine Arthritis Encephalitis (CAE)
CAE is a retroviral disease spread primarily through infected colostrum and milk. Young kids may develop encephalitis, while adult animals present with progressive joint swelling, particularly in the knees, and a gradual wasting condition. There is no treatment. Testing breeding stock and separating kids from infected dams at birth — using heat-treated colostrum or colostrum from tested negative animals — is the management approach.
Respiratory Disease
Pneumonia in goats is frequently polymicrobial, with Mannheimia haemolytica and Pasteurella multocida as key bacterial agents, often preceded by viral infection or stress. Poor ventilation, sudden weather changes, and overcrowding are major risk factors. Early signs include nasal discharge, increased respiratory rate, and fever. Prompt veterinary treatment with appropriate antibiotics can be effective if caught early.
Vaccination Schedules for Goats
Core vaccinations vary by country, but clostridial cover is universally recommended. A combined clostridial vaccine (typically covering Clostridium perfringens types C and D, plus tetanus) should form the foundation of every goat health programme.
- Kids: primary course of two injections four to six weeks apart, starting from four to eight weeks of age
- Does: booster three to four weeks before kidding to maximise passive immunity transfer via colostrum
- Annual boosters for all adult animals
- Any animal with an unknown history should receive a primary two-dose course before relying on single annual boosters
Always consult your vet about regional disease risks. In some areas, vaccination against pasteurellosis, foot-and-mouth disease, or other endemic conditions may be recommended alongside the core clostridial programme.
Internal Parasite Control: The Biggest Challenge in Goat Keeping
Haemonchus contortus: The Barber's Pole Worm
Haemonchus contortus is the single greatest health threat to goats in most of Europe, Australia, and the Americas. This blood-sucking abomasal worm causes anaemia, bottle jaw (submandibular oedema), and death. Unlike sheep, goats metabolise anthelmintics more rapidly and require higher dose rates — always seek veterinary guidance on correct dosing rather than following sheep product labelling.
FAMACHA Scoring and Targeted Selective Treatment
The FAMACHA system allows keepers to assess anaemia by examining the colour of the ocular mucous membranes and treat only those animals showing clinical signs. This approach, combined with faecal egg count monitoring, reduces the overuse of anthelmintics and slows the development of drug resistance. Blanket treatment of entire herds is now widely discouraged.
Pasture Management
Larvae survive on pasture, so rotational grazing, mixed-species grazing with cattle or horses (which do not share goat parasites), and resting paddocks for several weeks are all effective tools. Avoid overgrazing, which forces animals to graze closer to the ground where larval burdens are highest.
External Parasites and Foot Care
Lice and mange mites cause significant welfare concerns in goats, presenting as scratching, hair loss, and skin thickening. Treatment depends on the species involved; your vet can advise on appropriate licensed products. Foot care is equally important — goats are susceptible to footrot (Dichelobacter nodosus), foot scald, and foot-and-mouth disease. Regular hoof trimming, footbathing with zinc sulphate solution, and prompt treatment of lame animals reduce herd-level lameness substantially.
Key Action Points for Goat Keepers
- Establish a vaccination programme with your vet, centred on clostridial cover as a minimum
- Conduct regular FAMACHA scoring and faecal egg counts rather than routine blanket dosing
- Use correct anthelmintic doses for goats — sheep doses are typically insufficient
- Test breeding stock for CAE and manage colostrum feeding of kids accordingly
- Maintain good biosecurity when introducing new animals: quarantine for at least three weeks
- Ensure adequate ventilation in housing to reduce respiratory disease risk
- Trim hooves every six to eight weeks and footbathe regularly
- Record all treatments, vaccinations, and health events as a legal and management requirement
Goat health management rewards consistency. Building a relationship with a vet experienced in small ruminants is one of the most valuable investments a goat keeper can make.
