In Nigeria, where goat farming plays a vital role in rural economies and food security, maintaining the health of your herd is paramount. Goat vaccination stands as one of the most effective tools in preventing devastating diseases that can lead to significant losses. By implementing a robust goat vaccination programme, farmers can protect their animals from common infections, reduce mortality rates, and improve overall productivity. This article delves into the key aspects of goat vaccination, drawing from established guidelines to help Nigerian farmers make informed decisions. Whether you’re a smallholder or managing a larger operation, understanding goat vaccination is crucial for sustainable farming.

The Importance of Regular Goat Vaccination

Goat vaccination is not just a recommendation; it’s a necessity for all goats, regardless of age or breed. Experts advise vaccinating goats at least twice a year, with additional checks and adjustments if an animal falls ill. This routine helps build immunity against a range of bacterial, viral, and parasitic threats that are prevalent in tropical climates like Nigeria’s. For instance, vaccines such as Multivax-P Plus should be administered annually in September to guard against issues like enzootic abortion, brucellosis in goats and sheep, and internal parasitic worms. Incorporating goat vaccination into your farm management can prevent outbreaks that might otherwise decimate your herd.

One of the core components of goat vaccination is the CD-T combined vaccine, which targets Clostridium perfringens types C and D, along with tetanus. This vaccine is essential because goats are highly susceptible to enterotoxaemia, a condition that can be fatal if not addressed. Similarly, vaccines for pulpy kidney and blackleg, such as Pulpkidney, provide critical protection. Brucellosis, caused by Brucella melitensis bacteria, leads to abortions, swollen testicles, mastitis, and lameness. In such cases, treatments like oxytetracycline combined with streptomycin can be used, but prevention through goat vaccination is far more effective. Products like Coglavax and Pulpkidney Vaccine offer defence against clostridial toxins, while Botuvax immunises against botulism in cattle, sheep, and goats.

Vaccines for Specific Diseases in Goats

A comprehensive goat vaccination strategy must address specific diseases that affect goats in Nigeria. Pasteurellosis, which causes pneumonia, can be combated with the OBP Pasteurella vaccine for sheep and goats. In outbreaks, antibiotics like penicillin V, doxycycline, or long-acting tetracyclines such as oxytetracycline are recommended. Caseous lymphadenitis (CLA), a contagious disease caused by Corynebacterium pseudotuberculosis, requires vaccines like Linfovac, Biodectin, Glanvac 3, or those from Zoetis. All animals should receive annual booster doses, with goats needing revaccination every six months to maintain immunity against enterotoxaemia.

For clostridial diseases, the CDT vaccine (also known as CD&T) is widely used for Clostridium perfringens type C + D and tetanus. This is one of the must-have vaccines for anyone raising goats. Chlamydia abortion, occurring in the first 28-45 days of pregnancy, leads to abortions in the last two months, with fresh-appearing foetuses and no clinical illness in the doe. Caused by Chlamydia psittaci, it’s a major cause of abortions and stillbirths. Treatment involves tetracycline or tylosin, but goat vaccination with appropriate products is key to prevention.

Poxvirus, also known as Orf or sore mouth, often self-heals, but the Ovine Ecthyma vaccine can be applied as one drop on the affected area. Peste des Petits Ruminants (PPR), a viral disease with a 3-6 day incubation period, can kill goats within 5-10 days. Symptoms include diarrhoea, depression, and nasal discharge. There’s no specific treatment, but secondary bacterial and parasitic infections can be managed with antibiotics like oxytetracycline, chlortetracycline, ceftriaxone, gentamycin, along with 5% dextrose, multivitamins, and meloxicam. Prevention relies on the PPR vaccine, as it’s caused by a morbillivirus related to rinderpest. Disinfectants like phenols or 2% sodium hydroxide, combined with biosecurity, are essential.

Contagious Caprine Pleuropneumonia (CCPP), with a 6-10 day incubation, is caused by Mycoplasma capricolum subsp. capripneumoniae. Signs include severe fever, respiratory distress, coughing, sneezing, nasal discharge, dyspnoea, pyrexia, pleurodynia, and general malaise. Treatment involves tylosin at 10mg/kg every 24 hours for three days, or antibiotics like penicillin G, oxytetracycline, procaine, or dihydrostreptomycin sulphate. The CCPP vaccine is vital for prevention, emphasising the role of goat vaccination in herd health.

Goat Vaccination for Newborn Kids and Pregnant Does

Special attention must be given to newborn kids in any goat vaccination plan. Administer Pulp Kidney to goat kids from three weeks of birth, followed by Pulpyvax at three months old, with a second dose 4-6 weeks later, and then annual boosters. Pregnant does should receive the vaccine 30 days before kidding to pass on passive immunity through colostrum. Always read the vaccine manufacturer’s guidelines before proceeding, as not all vaccines are licensed for goats.

The goal of goat vaccination is to stimulate an immune response that protects adults and confers passive immunity to kids via colostrum. While vaccines don’t offer complete protection, they reduce disease severity and frequency. Key diseases with available vaccines include clostridial enterotoxaemia and tetanus, pneumonia (pasteurellosis), caseous lymphadenitis (CL), and infectious causes of abortion. For enterotoxaemia, products like Bar-Vac 10, One Shot Ultra 7, Multivax P, or Oviclos P are recommended, as goats are extremely susceptible. For CL, Glanvac 3 helps decrease incidence, though in some regions, positive animals may be culled.

For abortion causes, Ovilis Enzovax or similar products are useful. If reproductive issues arise, consult a veterinarian to identify infectious agents. Factors like nutrition, stress, and general health influence vaccine effectiveness, so administer to healthy animals only.

Research indicates shorter immunity duration in goats compared to sheep or cattle, suggesting vaccinations every 3-4 months for enterotoxaemia, though every six months may suffice in some cases. Initial vaccinations need a booster four weeks later. Kids should start at 6-8 weeks, before weaning, with boosters 3-6 weeks after. If born to unvaccinated does, vaccinate within two weeks. Tetanus protection is crucial, especially with banding castration. Vaccinate ewes 30 days pre-kidding for colostral antibodies, and don’t overlook bucks or replacements with unknown status.

Best Practices and Considerations in Goat Vaccination

Implementing goat vaccination effectively requires adherence to guidelines. Choose vaccines based on local disease prevalence and veterinary advice. In Nigeria, where environmental factors like humidity and parasites exacerbate risks, a tailored approach is essential. Biosecurity measures, such as quarantine for new animals and proper disinfection, complement vaccination efforts.

Remember, goat vaccination isn’t a one-size-fits-all solution. Monitor your herd for signs of disease and adjust schedules accordingly. Regular boosters ensure sustained immunity, particularly against clostridial diseases. By prioritising goat vaccination, Nigerian farmers can safeguard their livelihoods, reduce veterinary costs, and contribute to healthier livestock populations.

In conclusion, goat vaccination is the cornerstone of preventive health in goat farming. With consistent application of the right vaccines and treatments, you can mitigate risks from diseases like brucellosis, PPR, CCPP, and more. Aim for at least biannual vaccinations, consult professionals, and stay informed about product updates. Healthy goats mean prosperous farms, invest in goat vaccination today for a brighter tomorrow.
