In Zimbabwe, tick-borne diseases pose a significant threat to cattle. Among these diseases, Theileriosis, also known as “January disease,” has been particularly devastating.
1. Theileriosis (January Disease):
Theileriosis is one of the four major tick-borne diseases in Zimbabwe.
In recent years, Zimbabwe has lost around half a million cattle to Theileriosis, impacting livelihoods and farming communities. Theileriosis, caused by protozoa of the genus Theileria, is transmitted by ticks of the genus Rhipicephalus. This disease can cause fever, anemia, weakness, and death in cattle.
2. Other Tick-Borne Diseases:
Anaplasmosis: Anaplasmosis is caused by the bacteria Anaplasma marginale and is transmitted by the brown ear tick (Rhipicephalus appendiculatus). Infected animals may experience symptoms such as fever, anemia, jaundice, and decreased milk production.
Babesiosis: Babesiosis, also known as redwater fever, is caused by protozoa of the genus Babesia and is transmitted by various tick species, including Rhipicephalus (Boophilus) spp. and Amblyomma spp. Infected animals may exhibit symptoms such as fever, anemia, jaundice, and hemoglobinuria.
Heartwater: Heartwater, caused by the bacterium Ehrlichia ruminantium, is transmitted by Amblyomma spp. ticks. Infected animals may display symptoms such as fever, neurological signs, respiratory distress, and even sudden death.
Here are some strategies to help prevent and manage these diseases:
Regular Dipping: Compulsory short interval dipping of cattle is enforced in Zimbabwe. Dipping helps control ticks and reduces the risk of tick-borne diseases. It’s essential to follow recommended dipping schedules.
Vaccination: Some tick-borne diseases can be prevented through vaccination. Consult with veterinary professionals to determine the appropriate vaccination protocols for your livestock.
Prompt Diagnosis and Treatment: Early detection is crucial. If you suspect a tick-borne disease, seek veterinary assistance promptly. Administer antibiotics containing oxytetracycline as soon as the disease is diagnosed and provide supportive treatments to aid recovery.
Integrated Tick Control: Implement effective tick control measures. This includes regular dipping, strategic use of acaricides, and managing tick habitats.
Benefits of using a spray race:
Effective Disease Control: Spray races ensure complete drenching of cattle with acaricides, controlling tick-borne diseases.
Efficiency and Reduced Labor: They handle large herds efficiently with minimal labour requirements.
Waste Reduction and Recycled Acaricide: Less water usage, no acaricide ingestion, and recycling of spray wash.
Animal Welfare and Stress Reduction: Less stressful for cattle, suitable for weaker animals, and reduced mishaps.
Flexibility and Adaptability: Portable and suitable for other livestock like goats and sheep.
