Extract

It is well established that the equid olfactory system is highly sensitive. It has been suggested that there is an intimate link between the sense of smell in the horse (Williams, 1995) and the fight and flight response, which is mediated by the autonomic nervous system (Marlin and Nankervis, 2002), thus affecting the heart. In humans, it has been demonstrated that lavender can have a pronounced impact on heart rate variability (Saeki, 2000) but it is not yet know whether the autonomic nervous system of the horse can be influenced by odour. It is the aim of the study to determine the effect of odour on the autonomic status of the horses.

Eight geldings were used in the study and the electrical activity of their heart was assessed using the “Polar S810” telemetric system before and during the presentation of either pig faeces or lavender to the horses’ nostrils. The experiment was conducted over a two–day period so that their response to both odours could be determined.
