Abstract: The paper reviewed the effects of music and stock density on the growth performance and carcass quality for crossbreed broilers. The results showed that music can remarkably enhance the feed conversion（P<0.05）， and reduce the death-rate（P<0.05）. The results also indicated that music can increase the abdomen-fat rate，liver rate and PE，but decrease the brisket rate and leg muscle rate（P<0.05）in high stocking density. Stocking density only have markedly effect on briskets rate（P<0.05） with music，the briskets rate of high stocking density is lower than that of low stocking density.
