Effect of Music Rhythm on Growth Performance of Growing Pigs
Keywords:pig, environment, performance, audio-stress
Fifteen crossbred barrows (Largewhite X Landrace X Duroc) with average live weight of 30 kg. were divided into 3 treatments (5 pigs/treatment) in a completely randomized design experiment to determine the effects of audio-stress on their growth performance. All the animals were fed with the corn-soybean based diet. The treatments were natural (silence) sounds, light music and rock and roll music during feeding times, respectively It was found that there was no significant difference in dry matter but the DRG of the pigs in the fast rhythm music groups was lower (P<0.05) and FCR was higher (P<0.05) than the other two groups. It was concluded that loud noise and fast rhythm music could lower growth performance of the pigs.
