Description	Milk acetone (AC) is important indicator of energy metabolism of cows. The goal was to investigate infrared method MIR–FT in terms of its calibration for milk AC and to develop an usable procedure. Microdiffusion photometric (485 nm; Spekol 11) method with salicylaldehyde as reference (Re) and mid infrared spectroscopy FT (MIR–FT: Lactoscope FT–IR, Delta; MilkoScan FT 6000, M–Sc) as indirect method were used. The acetone addition to milk had no recovery using MIR–FT (Delta). The reference AC set has to have an acceptable statistics for good MIR–FT calibration (M–Sc). It was 10.1 ± 9.74 at geometric mean 7.26 mg.l–1, variation range from 1.98 to 33.66 mg.l–1. AC correlation between Re and MIR–FT (Delta) was low 0.32 (P > 0.05). Log AC relationship between Re and MIR–FT (M–Sc) was markedly better 0.80 (P < 0.01). The conversion of > 10 mg.l–1 as AC subclinical ketosis limit was: > –0.80 (feedback 0.158 mmol.l–1 = 9.25 mg.l–1) and > –1.66, important for ketosis monitoring by M–Sc.
