Observations on the Effects of Music Exposure to Growing Performance of Meat-Type Chicks

Abstract

One hundred eight-day old meat type chicks were randomly allotted into a control group and four music exposure treatment groups as follows: high level dinner music, low level dinner music, low level rock and roll music, and high level rock and roll music. Low level music reached a maximum decibel reading of 70 and high level music a maximum reading of 85. Feed consumption by group and individual weights were determined weekly during a nine-week feeding period. Feed consumption by groups was very similar and did not indicate any apparent tranquilizing effect or stress associated with treatments. Final live weight and carcass weight of the high level rock and roll group were somewhat less heavy than the others with the difference between low level dinner (1491 g.) and high level rock and roll (1398 g.) approaching statistical significance (P < .1).
