Ticks on cows: what to do? - briefly
Conduct routine herd inspections and treat identified infestations with veterinary‑approved acaricides according to label instructions. Complement chemical control with pasture rotation, controlled burning, and regular animal grooming to suppress tick populations.
Ticks on cows: what to do? - in detail
Infestation of cattle with ticks requires immediate assessment, targeted treatment, and preventive management.
First, identify the species present. Common culprits include Rhipicephalus (Boophilus) microplus, Ixodes ricinus, and Dermacentor spp. Species determination guides chemical choice because resistance patterns vary.
Second, quantify the burden. Count attached ticks on a representative sample of animals (e.g., 10 % of the herd). If more than two ticks per animal are observed, initiate control measures.
Third, implement an acaricide regimen. Options include:
- Synthetic pyrethroids – effective against susceptible populations; apply as pour‑on, spray, or dip.
- Organophosphates – useful where pyrethroid resistance is documented; observe withdrawal periods.
- Macrocyclic lactones (e.g., ivermectin) – provide systemic protection; administer subcutaneously or orally.
- Biological agents – entomopathogenic fungi or botanical extracts for integrated approaches.
Rotate active ingredients every 4–6 weeks to delay resistance. Record dates, products, and dosages in a herd health log.
Fourth, address environmental sources. Conduct pasture management by:
- Mowing or harrowing to reduce vegetation height where ticks quest.
- Rotating cattle to tick‑free pastures for at least two weeks after treatment.
- Applying residual acaricide to high‑risk zones (water troughs, shade trees).
Fifth, strengthen animal immunity. Maintain optimal nutrition, vaccinate against tick‑borne diseases (e.g., babesiosis, anaplasmosis), and monitor body condition scores regularly.
Finally, establish a monitoring schedule. Perform biweekly inspections during peak tick season (spring–autumn) and adjust treatment protocols based on observed efficacy. Early detection and systematic response minimize production losses and protect herd health.
