Integrated Herd Health Management in Ankole Cattle:

A Practical Approach to Vaccination, Parasite Control, and Surveillance

By Dr Tinette van Wyk, ARC-Animal Production, Irene, South Africa

Introduction

Sustainable and profitable Ankole cattle production depends on a well-structured herd health program that goes beyond vaccination alone. While vaccination forms the backbone of disease prevention, optimal herd performance is achieved through the integration of parasite control, ongoing surveillance, and strategic seasonal management.

This article outlines a practical, field-applicable approach to combining vaccination programs with internal and external parasite control, tailored to Southern African conditions.

A Holistic Herd Health Strategy

An effective herd health system is built on four key pillars:

Vaccination Programs
Internal Parasite Control
External Parasite Control
Surveillance and Monitoring

These components must work together and not in isolation, to ensure optimal animal health, productivity, and sustainable production.

Surveillance

The foundation of decision-making is surveillance. Routine monitoring is often overlooked but is critical for informed management decisions.

Annually test the whole herd for tuberculosis and brucellosis
Conduct post-mortems on unexplained deaths
Use blood smears for tick-borne disease diagnosis
Perform body condition scoring (BCS) every 2–3 months
Conduct external parasite monitoring
Inspect animals every 2–3 weeks during high-risk seasons. Focus on predilection sites such as ears, tail switch, and underbelly
Treat infestations promptly rather than waiting for scheduled treatments

Internal Parasite Monitoring and Control

Rather than relying on routine blanket dosing, producers are encouraged to implement:

Faecal Egg Counts (FEC)

Every 2–3 months during summer
Every 4–6 months during winter
Focus on young stock and animals in poor condition

Which class of dewormer should be used
Disease surveillance

Internal parasites remain a major production constraint in cattle systems.

Key parasites to monitor for are:

Gastrointestinal roundworms (notably Haemonchus)
Liver fluke in wet or marshy areas
Coccidia in young calves

To minimize resistance and maximize effectiveness, dosing should be strategic:

Late summer (Feb–March): Target peak worm burdens
Early winter (May–June): Reduce carry-over infections
Late winter/early spring (Aug–Sept): Prevent build-up before the rainy season

To control Liver Fluke in high-risk areas treat at the end of summer and mid-winter. Use appropriate flukicides and observe withdrawal periods.

Treating Calves

Give calves their first treatment at 6–8 weeks old. Repeat every 2–3 months until one year of age. During this period monitor for signs of coccidiosis (diarrhoea, straining to defecate, dehydration and reduced appetite), especially under stress conditions.

External Parasite Control

External parasites significantly impact productivity through irritation, disease transmission, and stress.

Tick Control

Ticks are among the most economically important parasites in Southern Africa
Summer (Oct–March): Treat every 2–3 weeks
Winter: Treat only when necessary

To prevent resistance:

Rotate acaricide classes regularly
Implement fly and tick control
Tick loads generally peak during warmer months
Use pour-on’s, fly tags, or feed-through treatments where applicable

Lice Control

Lice are most prevalent in winter
Treat during mid-winter if infestations are detected
Integrating with the vaccination program

Proposed Vaccination and Monitoring Calendar

To improve sustainable production, parasite control and surveillance should align with existing vaccination schedules. Proposed vaccinations and monitoring protocols per month are detailed below:

March

Tuberculosis and brucellosis testing
Add faecal egg counts and targeted deworming if required

April

Clostridial and botulism vaccinations
Combine with internal parasite control where necessary

May–June

Lumpy skin disease vaccination period
Implement winter deworming and monitor external parasites

August

Rift Valley fever and other seasonal vaccinations
Initiate pre-rain parasite control and increase tick monitoring

Key Management Considerations

Avoid:

Routine blanket dosing without evidence
Repeated use of the same deworming class
Ignoring withdrawal periods

Implement:

Rotation of deworming classes
Quarantine protocols for new animals
Regular monitoring and record-keeping

Conclusion

An integrated herd health program that combines vaccination, targeted parasite control, and continuous surveillance is essential for maintaining the resilience and productivity of Ankole cattle.

By shifting from routine treatments to evidence based, strategic interventions, producers can:

Improve animal performance
Reduce input costs
Slow the development of drug resistance

Ultimately, this approach supports both economic sustainability and animal welfare, ensuring long-term success in Ankole cattle production systems.
