摘　　要：试验系统研究不同季节(春、夏、秋、冬)与养殖密度条件下(2.7、3.6、4.4只/m2)发酵床养殖对樱桃谷肉鸭生产性能的影响。结果表明:相比较传统的水养模式,不同季节发酵床养鸭均可显著改善肉鸭的成活率、出栏重和饲料报酬(P<0.05);夏季肉鸭成活率、出栏重与采食量均为最低,秋季肉鸭成活率、出栏重与总料重比为最优;不同饲养密度条件下,发酵床养鸭较传统水养均可显著提高肉鸭成活率和料重比(P<0.05),且肉鸭生产性能随着养殖密度的降低而提高。结论:不同季节和饲养密度条件下,发酵床养殖均可改善肉鸭部分生产性能,肉鸭生产性能随饲养密度降低而改善。This experiment was conducted to investigate the effect of deep litter system on the produc- tion performance of meat duck in different seasons （spring, summer, autumn and winter） and with different stocking densities （2.7, 3.6,4.4 birds/m2）. The results showed that,compared with the traditional water raising system,deep litter system could significantly improve the survival rate, final weight and feed con- version in different seasons （P〈0.05） survival rate, final weight and feed intake of meat duck were the lowest in summer and the highest in autumn deep litter system also could significantly increase the birds＇ survival rate and feed conversion with different stocking densities. In addition, the duck production per- formance was improved when the stocking density decreased. It could be concluded that deep little system improved the performance of meat duck in different season and with different stocking density, and the duck＇s production performance increased with the decrease of stocking density.
