The aim of the study was to determine the first reaction of the heart rate (HR) in horses to piping music of different genres into the stable for a short time. The study included 26 saddle horses, mares, stallions and geldings, split into three age groups: 1-5, 6-11 and over 11 years. Three kinds of music were played within three 25-minute tests conducted on three successive days, one test a day. The tests differed in the sequence of music genres: rock, country and relaxing music. The analysis considered the mean HR at rest and during the first two and three minutes of the whole sequence of the three music genres, as well as during particular genres: minimum and maximum HR, difference between maximum HR and HR at rest, as well as the time in which HR decreased from the maximum level to the level before music was played. The data were verified by T-Tukey’s test and by ANOVA (GLM) with regard to sex, age group and music test factors. The results show that music played at 80 dB caused a short HR elevation. The level of emotional excitability measured by HR was different for the three music genres. The relaxation music had the mildest effect, the country music acted more strongly, and the influence of the rock music was the strongest. This finding is based on the mean HR for the first two minutes of a music test, extreme HR, difference between maximum HR and HR at rest, as well as the time in which HR decreased from the maximum level to the level before music was played. Differences in reactions of the horses to music were related to their sex and, to a smaller degree, their age.

The objective of the study was to determine the activity of the sympathetic and parasympathetic systems associated with various kinds of behaviour in Thoroughbred yearlings during initial training by natural methods. The initial training lasted approximately one hour a day for three successive days. Each day, the behaviour of each colt during the first 15 minutes of training was filmed. During training, a telemetric device was used to measure heart rhythm parameters: heart rate (HR per minute), which shows the activity level of the sympathetic system, and RMSSD (root mean square of two successive RR intervals in QRS curve; ms), illustrating the activity level of the parasympathetic system. On the basis of the film, the frequency of 10 most typical kinds of behaviour was estimated. The synchronization of the film with the heart rhythm parameters record made it possible to determine the mean values of these parameters for particular kinds of behaviour. The results show that on the successive days of training, the activity of the parasympathetic part of the autonomic system increased, and the frequency of reactions decreased. The heart rhythm parameters show that, among the typical reactions to training, four kinds of behaviour are desirable: turning the head towards the trainer, low position of the head, turning ears towards the trainer and licking the lips. Other kinds of behaviour, that is, running away, a high position of the head, vocalization, teeth grinding, tail movements to the sides and defecation, are undesirable. The highest excitability is associated with running away and a high position of the head, whereas the head turned towards the trainer and a low position of the head show that the horse is calm.
