摘要
该文就音乐及饲养密度对笼养肉杂鸡的生产性能及屠宰性能进行了初步探讨。试验表明音乐可显著降低死淘率,提高料肉比。音乐显著提高肉杂鸡的全净膛率、腹脂率、肝脏比率(P＜0．05)。高密度情况下,音乐显著降低胸肌率和腿肌率(P＜0．05)。饲养密度仅在有音乐的情况下对胸肌率具有显著性的影响,高密度的胸肌率低于中低密度的胸肌率。
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.
