Abstract

The authors compared heart rate (HR) and heart rate variability (HRV) parameters of dairy cows (N=18; parity: 2.34±1.12; milk yield: 24.40±6.78 kgld; DIM: 148.30±57.44) during milking in a conventional system to those of the same animals when milked after changeover to an automatic milking system. They analyzed HRV parameters in frequency (IF, HF, IF/HF) and geometric domain by Poincaré plot (SD1, SD2, SD2ISD1). When conventional milking was in operation, HR was higher in the holding area, before entering the milking parlour/milking unit and during milking (P=0.000; P=0.000; P=0.046, respectively) compared to HR in the mentioned phases in the automatic milking system. Sympathetic HRV parameters SD2 and 5D2/SD1 measured in the conventional system during the phases of waiting in the holding area, before entering the milking parlour/milking unit, and during udder preparation were also higher compared to automatic milking (P=0.012 and P=0.013; P=0.0012 and P=0.004; P=0.033 and P=0.031, respectively). Based on the results, the conventional milking process imposed greater stress on the animals, particularly in the holding area, before entering the milking parlour/milking unit and during udder preparation.
