In the milking parlour, feeding with concentrates was analysed in order to establish whether too short time for the consumption of concentrate caused increased heart rate (HR), one of the stress indicators. Average HR was 82.38 min-1. In the evening, milking cows had higher HR (83.4 min-1), compared to the morning one (81.2 min-1). In the second month after calving, HR of cows was higher (85.10 min-1) compared to the first (81.04 min-1) and the third month (80.79 min-1) after calving. Higher quantity of consumed concentrate (over 3 kg) resulted in an increased HR. If the cows received larger quantities of concentrate, HR increased towards the end of milking process. It can be concluded that large quantities of concentrate, which could not be consumed in a short period of available time during milking, caused stress in highly productive dairy cows.

Key words: heart rate, dairy cows, milking parlour, Polar monitors


Merjenje srčnega utripa krav v molzišču

V molzišču je bilo proučevano dodajanje koncentrata molznicam kot možnost kratkega časa za zauživanje krme kot povzročitelja povečanja srčnega utripa (SU) kot enega izmed indikatorjev stresa. Poprečni SU je bil 82,38 min-1. V večerni molži so imele krave višji srčni utrip
(83.4 min-1), v primerjavi z velikostjo SU v jutranji molži (81,2 min-1). V drugem mesecu laktacije so imele krave višji SU (85,1 min-1) v primerjavi s prvim in tretjim mesecem laktacije (81,04 min-1; 80,79 min-1). Večja konzumacija koncentrata (preko 3 kg) se izraža v povišanem SU. V primeru, da so krave dobile večje količine koncentrata je SU narastel proti koncu molže. Lahko zaključimo, da večje količine koncentrata v zelo kratkem času molže povzročajo stres pri visoko produktivnih kravah.
