We conducted this experiment with the aim of investigating the effects of different noise levels from ventilation fans on the growth and slaughter performance, meat quality, blood parameters, and feeding behavior of geese from 21 to 70 days of age. A total of 108 male geese (21-day-old) were randomly assigned to one of three conditions: a control group (no additional fan noise), low-noise treatment (65–75 dB), and high-noise treatment (85–95 dB). Each treatment included six replicates, with six geese per replicate. The results showed that neither ventilation fan noise level significantly affected growth performance, feeding behavior, slaughter performance, or major meat quality traits (p > 0.05). Compared with the control group, noise exposure significantly reduced circulating adrenocorticotropic hormone and corticosterone concentrations (p 0.05). Overall, prolonged noise stimulation (65–75 dB and 85–95 dB) alleviated stress responses in commercial geese aged 21–70 days, without negatively affecting their growth performance, slaughter performance, meat quality, or feeding behavior.
