How Zimbabwean Cattle Herders Are Innovating To Manage January Disease
Since 2016, January disease, also known as theileriosis, has wreaked havoc on cattle populations across rural Zimbabwe, claiming more than half a million animals. This devastating blood parasite, Theileria parva bovis, transmitted by the brown ear tick (Rhipicephalus appendiculatus), has forced cattle herders into a battle for survival, impacting not only livestock numbers but also livelihoods dependent on ploughing, manure, and milk production.
The outbreak’s severity varied across regions, with wetter areas experiencing more intense infections due to higher tick prevalence. For instance, Matobo District, noted for its drier climate, has remained relatively unscathed, highlighting the tick’s environmental sensitivities. Conversely, places like Zvishavane, Gutu, and Mvurwi have faced repeated battles against this relentless disease.
The impact on livelihoods and food security
FFA’s Zimbabwean field research indicates that many farmers describe January disease as the most significant shock in recent years—derailing their progress and pulling families back from improved economic and food security pathways. Entire herds wiped out translate into fewer draught animals to till fields, diminished manure for soil fertility, and reduced milk supplies, crucial for household nutrition and income.
Diverse approaches to treatment and prevention
In the absence of consistent government veterinary services, farmers have innovated and adapted a variety of strategies to combat the disease. These range from traditional plant-based remedies to biomedicines, often sourced both locally and from neighbouring countries such as South Africa and Zambia.
Traditional medicines and religious practices: Many herders use local plant concoctions known as ‘maguchu’, powerful drenches administered orally to sick animals. These recipes are closely guarded secrets within communities. Additionally, some local church pastors promote spiritual protection against the disease, administering “minato”—holy water or mealie meal—believing divine intervention can shield their herds.
Biomedical treatments and local experimentation: Oxytetracycline-based antibiotics like Terramycin, Limoxin, and Penicillin are widely used, though responses vary. Some farmers, frustrated with conventional treatments, have developed innovative protocols. In Mvurwi, farmer LC observed that death was linked to constipation caused by the disease. He administers cooking oil as a laxative followed by consecutive antibiotic injections, an approach that has remarkably stopped losses in his herd of over 60 cattle. Similarly, another herder, EC, uses unused motor oil with salt to relieve digestive blockages with notable success.
Emergence of local specialist veterinary services: In Zvishavane’s Siboza area, retired wildlife veterinarians now provide treatment services, charging fees to help farmers manage outbreaks. Entrepreneurs buy sick animals cheaply, treat them successfully using acquired veterinary knowledge, then build profitable herds, illustrating grassroots business models emerging from the crisis.
Challenges with trust and medicine efficacy
Despite these efforts, a pervasive distrust of modern biomedicines has grown. Many farmers report inadequate results from locally available drugs and acaricides, leading some to prefer medicine imports from South Africa and Zambia. Timely diagnosis and correct dosages remain critical for treatment success, alongside rigorous herd monitoring. Vital symptoms such as loss of appetite, swollen lymph nodes, and breathing difficulties must be recognised early to improve survival rates.
Zimbabwean policy and the National Development Strategy 1 (NDS1)
Combating January disease aligns directly with Zimbabwe’s National Development Strategy 1 (NDS1), which prioritises agricultural resilience, youth engagement, and women’s empowerment. By integrating local expertise, encouraging youth involvement in innovative veterinary practices, and supporting women farmers with access to effective treatments and education, the sector can improve disease management and livestock productivity.
The way forward: participatory disease surveillance and research
Zimbabwean farmers’ adaptation to January disease underscores the urgent need for an integrated, participatory approach to animal health. The current fragmented efforts must evolve into a coordinated national strategy involving veterinary services, local specialists, researchers, and the farming community. This will enhance disease surveillance, increase treatment efficacy, and enable responsive interventions tailored to shifting disease ecologies impacted by climate change and land use alterations.
In practice, this might mean:
- Establishing community-based animal health worker networks trained in early disease recognition and treatment.
- Funding collaborative research projects to validate and improve local treatment innovations such as those pioneered in Mvurwi and Zvishavane.
- Ensuring supply chains for effective acaricides and biomedicines are resilient and reach remote areas.
- Supporting knowledge-sharing platforms that respect and document traditional medicines and local expertise.
The devastating economic losses from January disease—running into hundreds of millions of dollars—justify urgent investment in these areas. Zimbabwe’s experience offers a powerful example of resilience and ingenuity among cattle herders, providing valuable lessons for other African countries battling similar livestock diseases.
Zimbabwe case study: LC’s innovative approach in Mvurwi
LC, a cattle farmer in Mvurwi, exemplifies successful local innovation in disease management. After observing the ineffectiveness of standard antibiotic treatments alone, he identified constipation as a key issue contributing to animal deaths. Combining a laxative dose of cooking oil with carefully timed injections of oxytetracycline-based medicines, LC has maintained a zero-mortality record since the onset of January disease in his community. His approach, while unconventional, highlights the critical role of hands-on experimentation and observation in managing emerging veterinary challenges.
FFA explainer box: What Is January Disease?
January disease, or theileriosis, is a cattle illness caused by protozoan parasites transmitted through tick bites. It leads to fever, swollen lymph nodes, breathing difficulties, and often death if untreated. The brown ear tick is the main vector. Early detection, tick control through dipping, and effective medication are essential for managing the disease. Climate conditions such as wet seasons favour tick proliferation, increasing outbreak risks.

As Zimbabwe navigates the intricate challenges posed by January disease, strengthening collaboration between government, veterinary experts, researchers, and farming communities will be vital. Elevating local knowledge and integrating scientific research will ensure sustainable livestock health, bolster rural incomes, and contribute to national food security and economic growth under the NDS1 framework.
