Abstract: In order to clarify the physiological effects of noise on meat ducks and improve the animal welfare of meat ducks, 60 ducks were randomly divided into 3 groups. The 80 and 100 dB noise were applied by noise generator to establish stress model in experimental group 1 and 2, respectively. The control group did not apply noise stress. Liver, spleen, lung and kidney tissues were collected after the stress treatment. RT-PCR was used to detect the expression of HSP70 and HSP90 mRNA in each tissue. The results showed that transcription levels of HSP70 and HSP90 mRNA in the liver, spleen, lung and kidney of experimental group 1 and 2 were significantly higher than those in the control group (P<0.01), and the transcription levels of HSP70 and HSP90 mRNA in experimental group 2 were significantly (P<0.01) higher than those in experimental group 1. Therefore, acute noise stress would increase the transcript of HSPs mRNA in the internal organs of meat ducks.

Key words: noise stress, meat duck, HSP70, HSP90
