The purpose of this study is to investigate the
effects of both music and frequency of sound on egg-damaging in Japanese quail
under controlled environmental conditions. For integrative investigation of the
effects of music and frequency on the complex interrelation between
egg-damaging and sound, we measured egg yield and behaviour characteristics. 48
female and 8 male Japanese quails (Coturnix
coturnix japonica) were randomly divided into two groups with two
replicates. The experiments were carried in two phases. In the first phase of the study, individuals in
the experimental group were exposed to classical music for 10 days to a total
of 30 hours in a scheduled program. It is determined that the experimental
results obtained from individuals in the experimental group of eggs, damaged
egg / egg ratio is 1/17 as the lowest, 1/10 as the highest. This value is
observed that 3 / 13 is the lowest, 5 / 7 is the highest in the control group.
In the second phase, with specified time intervals subjects were exposed to
different frequencies. Frequency experiments were carried out in 3 stages (500
Hz, 600 Hz and 400Hz). Whenever the effects of the frequencies and the time intervals
on the subjects were examined, it is determined that the ratio of damaged eggs/
eggs is 1/16 as the lowest, is 2/16 as the highest, whence the eggs obtained
from the individuals of experimental cages, listened to 600 Hz (Hertz)
frequency for 60 minutes per a day.
According to the results of these experiments, it is determined that quails
exposed to 600 Hz frequency per day reduced the damaged egg ratio and have a
positive impact on total egg weight.
