A non-contact laser thermometer Raynger ST-6 was utilized to quantify temperatures of the inward surfaces of liners immediately subsequent to draining. In a gathering of 12 dairy cows, the base liner temperature in the wake of draining was 15.3°C, the greatest temperature was 28.9°C. It follows from the relapse relationship that an expansion in the cooling time by 1 second reductions the temperature of the liner inward surface by 0.0324°C. All things considered, front left quarters were drained inactive 2.55 min, front right 2.21 min, back left 0.24 min, back right 0.56 min.
