“…Noise is described as an acute, chronic or intermittent sound [ 1 ], which can act as a potential stressor in farmed species such as pigs [ 2 ], [ 3 ], horses [ 4 ], goats [ 5 ],[ 6 ] and cattle [ 1 ],[ 7 ], [ 8 ], [ 9 ]. In piglets, Talling and colleagues [ 1 ] found that, within 15 min of acute exposures to various noise stimuli at 80–97 dB once per week over a total of 4 weeks, initial increase in heart rate and locomotion indicated an activation of the pigs’ defence mechanisms, followed by habituation.…”

“…In another study, exposure to repeated noise during daily sessions of 2 hours over a period of 4 weeks caused changes in neuroendocrine regulations that reflected a state of chronic stress in growing pigs [ 10 ]. Horses [ 4 ] and goats [ 5 ] spent less time feeding when exposed to acute noise for 1–2 min in a test arena. The goats habituated to the noise (chime of bell and sinusoidal sound with maximum amplitude of 96 dB) within 3 days, i.e.…”

“…The goats habituated to the noise (chime of bell and sinusoidal sound with maximum amplitude of 96 dB) within 3 days, i.e. from the third day of playbacks there was no difference between baseline and playback values in feeding and vigilance behaviour [ 5 ]. Whereas these studies were conducted in rather artificial situations, farm animals are confronted with several acoustic stimuli throughout their lives, including ventilation, feed carts, barn cleaners or the vacuum machine in the milking parlour.…”

Do Bells Affect Behaviour and Heart Rate Variability in Grazing Dairy Cows?

In alpine regions cows are often equipped with bells. The present study investigated the impact of wearing a bell on behaviour and heart rate variability in dairy cows. Nineteen non-lactating Brown-Swiss cows with bell experience were assigned to three different treatments. For 3 days each, cows were equipped with no bell (control), with a bell with inactivated clapper (silent bell) or with a functional bell (functional bell). The bells weighed 5.5 kg and had frequencies between 532 Hz and 2.8 kHz and amplitudes between 90 and 113 dB at a distance of 20 cm. Data were collected on either the first and third or on all 3 days of each treatment. Whereas duration of rumination was reduced with a functional bell and a silent bell compared with no bell, feeding duration was reduced with a silent bell and was intermediate with a functional bell. Head movements were reduced when wearing a silent bell compared with no bell and tended to be reduced when wearing a functional compared to no bell. With a functional bell, lying duration was reduced by almost 4 hours on the third day of treatment compared with the first day with a functional bell and compared with no bell or a silent bell. All additional behavioural measures are consistent with the hypothesis of a restriction in the behaviour of the cows wearing bells, although this pattern did not reach significance. There was no treatment effect on heart rate variability, suggesting that the bells did not affect vago-sympathetic balance. An effect of experimental day was found for only 1 out of 10 behavioural parameters, as shown by a decrease in lying with a functional bell on day 3. The results indicate behavioural changes in the cows wearing a bell over 3 days, without indication of habituation to the bell. Altogether, the behavioural changes suggest that the behaviour of the cows was disturbed by wearing a bell. If long-lasting, these effects may have implications for animal welfare.

“…Although, using music is a vital tool for improving piglets and dairy cows' welfare and behaviour where it reduces the stress on cows and increases milk yield (O'Brein, 2014). Animals may have negative effects on welfare if they are exposed to the music for long-term like goats in the alpine regions that are permanently equipped with chime bell (Johns et al, 2015). Music does not affect horses' behaviour when they are exposed to short term isolation distress.…”

“…Hence, sounds may possibly act as stressors. This depends on their amplitude and frequency (McAdieet al, 1993;Talling et al, 1998;Quaranta et al, 2002;Moore, 2012;Johns et al, 2015). Sheep are able to detect sounds at -6 dB and can hear sounds between 125 Hz to 42 KHz, with the best sensitivity at 10 KHz (Heffner and Heffner, 1990).…”

ABSTRACT:The present study was designed to determine whether playing two music types will improve behaviour of non-pregnant, nonlactating Arabi sheep. Thirty Arabi ewes, aged 2 -3 years, were included in the study. Ewes were divided into three groups, 10 ewes each. The groups were: Control (with no music exposure); Classic music exposure and Fast music exposure. The sound level for classic and fast music groups was 80 dB with the frequency of 1 KHz. The behavioural data were collected using direct observations for six respective days. Results revealed that using music, both classic and fast, significantly decreased the frequency of aggressive behaviours (P < 0.001), vocalization (P < 0.01), defecation (P < 0.05) and walking behaviour (P < 0.05). In addition, there were significant effects of music on the average time spent standing (P < 0.01), lying and feeding (P < 0.001). Whereas no significant difference was found on the average time spent drinking. It was shown that there were significant differences in time spent lying (P < 0.01) and time spent feeding (P < 0.01) over time. Finally, there was a significant difference in the proportion of time spent lying (P < 0.001) as well as in the proportion of time spent feeding between control and music groups (P < 0.01). From this study, it can be concluded that exposing non-pregnant, non-lactating ewes to classical music is beneficial for ewes' welfare, due to the reduction of aggressive behaviour.
