Tick infestation in tropical and subtropical cattle production causes significant welfare harm through blood loss, disease transmission, and the stress of heavy infestation.
Heavy tick infestation causes continuous welfare harm through blood loss, skin irritation, and immune activation in affected cattle. The combination of direct parasite burden and tick-transmitted disease creates a welfare double impact that severely compromises health and productivity. In tropical smallholder systems, livestock welfare from tick management is also a food security issue — productive cattle support family nutrition and income. Integrated tick management that combines genetic selection, strategic acaricide use, and biological control provides the most sustainable welfare improvement pathway.
