Effect of Music on Growth Performance, Carcass and Meat Quality in Broilers

Abstract

This study was conducted to investigate the effects of music on growth performance, carcass and meat quality characteristics and feed conversion rate in broilers. The study was conducted with 630 broiler chicks. One hundred five broiler chicks were randomly distributed into six groups with 105 birds in each. Of these, three groups were treatment groups and three groups were control groups. The animals in the experimental group were exposed to 78 dB music in intervals of 5 minutes and 5-minute pauses over a period of 6 weeks. A standard supply program was applied in the study. The animals in the study were weighed every week and the increase of the body weight was determined. While there was a statistically significant difference in feed conversion rate between treatment and control group (P<0.05), no statistically significant differences were found for live weight except for Week 4, carcass weight, leg weight, chest weight and gizzard weight (P>0.05). However, the differences between the heart and liver weights of control and experiment groups were statistically highly significant (P<0.01). Also the chemical composition of the meat sample was analyzed for the treatment and control groups. According to the analysis, there were statistically highly significant differences between treatment and control group in crude protein (P<0.01), and statistically significant effects on crude fat (P<0.05), while there were no statistically significant effects on dry matter and crude ash.
