Deepthi Infrared, thermography, a non-invasive, tool, ectoparasite, dairy cattle 67-69 Volume 2 (4) July 2026 Cattle raised under field or pasture conditions frequently endure infestations by multiple ectoparasite species simultaneously, which significantly affects livestock health and productivity.
