“…( 2013 ); Roy et al. ( 2014 )). Furthermore, a sound pressure level of 90 dB compared to 70 dB has been shown to result in earlier hatching, higher hatchability, better chick quality and lower weight at hatching (Donofre et al., 2020 ).…”

“…Excessive noise during incubation can influence social behaviour, fearfulness, cognition and stress reactivity of the chicks (Chaudhury et al., 2010 ; Kauser et al., 2011 ; Sanyal et al., 2013 ). It is a rather unexplored topic, but the nature of the noise, the sound pressure level and the pattern of noise are among the factors influencing the impact of the noise (Chaudhury et al., 2010 ; Kauser et al., 2011 ; Sanyal et al., 2013 ; Roy et al., 2014 ). The effects of noise demonstrated have mainly been short‐term (e.g.…”

This Scientific Opinion considers the welfare of domestic fowl (Gallus gallus) related to the production of meat (broilers) and includes the keeping of day-old chicks, broiler breeders, and broiler chickens. Currently used husbandry systems in the EU are described. Overall, 19 highly relevant welfare consequences (WCs) were identified based on severity, duration and frequency of occurrence: 'bone lesions', 'cold stress', 'gastro-enteric disorders', 'group stress', 'handling stress', 'heat stress', 'isolation stress', 'inability to perform comfort behaviour', 'inability to perform exploratory or foraging behaviour', 'inability to avoid unwanted sexual behaviour', 'locomotory disorders', 'prolonged hunger', 'prolonged thirst', 'predation stress', 'restriction of movement', 'resting problems', 'sensory under-and overstimulation', 'soft tissue and integument damage' and 'umbilical disorders'. These WCs and their animal-based measures (ABMs) that can identify them are described in detail. A variety of hazards related to the different husbandry systems were identified as well as ABMs for assessing the different WCs. Measures to prevent or correct the hazards and/or mitigate each of the WCs are listed. Recommendations are provided on quantitative or qualitative criteria to answer specific questions on the welfare of broilers and related to genetic selection, temperature, feed and water restriction, use of cages, light, air quality and mutilations in breeders such as beak trimming, de-toeing and comb dubbing. In addition, minimal requirements (e.g. stocking density, group size, nests, provision of litter, perches and platforms, drinkers and feeders, of covered veranda and outdoor range) for an enclosure for keeping broiler chickens (fast-growing, slower-growing and broiler breeders) are recommended. Finally, 'total mortality', 'wounds', 'carcass condemnation' and 'footpad dermatitis' are proposed as indicators for monitoring at slaughter the welfare of broilers on-farm.

“…This hypothesis is further confirmed by a study demonstrating that exposure to music in the perinatal period improves learning performance and alters BDNF signaling in adult mice [ 52 ] (Chikahisa et al, 2006). These results suggest the facilitation of postnatal synaptic plasticity after prenatal stimulation with music [ 53 ] (Roy et al, 2014), which could explain the higher concentration of BDNF in the MM treatment when compared to the others. Although the neurotrophic factor did not increase between birth and weaning in the MM group, music therapy may have inhibited the natural reduction of BDNF expression, leading to the maintenance of its concentration and a higher average compared to piglets in the other treatments at the same age, which showed statistically lower averages at weaning.…”

The rearing environment of pigs can cause a high level of stress due to the lack of stimuli and the impossibility of carrying out natural behaviors. Music therapy is a way to enrich the environment and promote stress relief. Few studies in swine using environmental enrichers focus on functional benefits, such as stress resilience, improved biological functions, or mental status. The effect of environmental enrichment on neurobiological processes is particularly poorly understood in farm animals. Thus, our study sought to elucidate the influence of music in piglets exposed to music therapy in the intrauterine and extrauterine phase on neuroplasticity, evaluating the levels of brain-derived neurotrophic factor (BDNF). Behavioural responses were also evaluated using fear tests related to stress resilience. The productive performance of these piglets was analysed to relate the possible reduction in stress levels to greater productivity gains. Forty-eight sows were used at 90 days of gestation until the weaning of their piglets. In the gestation phase, the sows were divided into two treatments: control (without music therapy) and music (with music therapy). In the farrowing/lactation phase, the sows were separated into four treatments: control-control (no music in any phase); control-music (music only in farrowing/lactation); music-control (music only during pregnancy); and music-music (music in both reproductive phases). Music therapy did not cause a difference in the BDNF levels of piglets at birth. However, piglets born from sows of the music-music treatment did not show a reduction in BDNF between birth and weaning, unlike the other treatments. Exposure to music in the last 1/3 of pregnancy and farrowing/lactation improved the weight of piglets at birth and at weaning. Musical enrichment during pregnancy and lactation was able to cause changes in the piglets’ neuroplasticity and improve their productive performances.

“…At a higher intensity, these patterned and rhythmic sounds have no harmful effects on the embryonic development of the auditory system, and spatial orientation and the ability to resist stress [ 3 , 28 – 30 ]. However, in other studies, unpredictable noise, such as vehicle honking, was used [ 6 , 30 32 ]. These dissonant and noisy structures are associated with aggression, fear and defense [ 27 , 28 ], which may be the main reason for the different results.…”

Objective: Early environmental enrichment in life can improve cognition in animals. The effect of prenatal auditory stimulation on learning ability and fear level in chick embryos remained unexplored.Therefore, this study investigated the effect of prenatal auditory stimulation on the learning ability and fear level of chicks.Methods: A total of 450 fertilized eggs were randomly divided into 5 groups, including control group (C), low-sound intensity music group (LM), low-sound intensity noise group (LN), high-sound intensity noise group (HN) and high-sound intensity music group (HM). From the 10 th day of embryonic development until hatching, group LM and group LN received 65-75 dB of music and noise stimulation.Group HN and group HM received 85-95 dB of noise and music stimulation, and group C received no additional sound. At the end of incubation, the one-trial passive avoidance learning (PAL) task and tonic immobility (TI) tests were carried out, and the serum corticosterone (CORT) and serotonin (5-HT) concentrations were determined. Results:The results showed that compared with the group C, 65-75 dB of music and noise stimulation did not affect the PAL avoidance rate (p>0.05), duration of TI (p>0.05) and the concentration of CORT (p>0.05) and 5-HT (p>0.05) in chicks. However, 85-95 dB of music and noise stimulation could reduce duration of TI (p<0.05) and the concentration of CORT (p<0.05), but no significant effect was observed on the concentration of 5-HT (p>0.05) and PAL avoidance rate (p>0.05). Conclusion:Therefore, the prenatal auditory stimulation of 85-95 dB can effectively reduce the fear level of chicks while it cannot affect the learning ability.
