摘　　要：为了探讨高生产性能的蛋鸭饲养模式,以替代传统饲养方式,试验研究了3种不同饲养方式(网上平养、笼养和散养)对山麻鸭产蛋期生产性能的影响。结果表明:经过231 d的饲养试验,笼养组每只山麻鸭的产蛋量和总蛋重分别为179.3枚和11.95 kg,极显著低于散养组(189.9枚和12.75 kg)和网上平养组(192.2枚和12.54 kg)(P<0.01),散养组与网上平养组差异不显著(P>0.05);网上平养组全期料蛋比为3.68,与散养组(3.58)差异不显著(P>0.05),二者极显著低于笼养组(4.56,P<0.01);网上平养组畸形蛋率为3.21%,极显著低于笼养组(5.44%)和散养组(4.12%,P<0.01),而笼养组极显著高于散养组(P<0.01)。说明网上平养的饲养方式不仅不影响山麻鸭的产蛋性能,而且能降低饲料消耗,可以替代传统的饲养方式。To investigate a rearing method with high productive performance for laying duck instead of traditional raising method, the effects of three different rearing methods including net, cage and free- range rearing on the productive performance of Shanma duck were studied during the laying period. The results showed that after 231 d of feeding trials the average egg number and the total egg weight per Shanma duck were 179.3 and 11.95 kg at 231 d in the cage rearing group, respectively ; which were extremely significantly lower （ P 〈 0.01 ） than those in the free - range rearing group （ 189.9, 12.75 kg） and the net rearing group （ 192.2, 12.54 kg） , and there was no significant difference （P 〉 0.05 ） between the free - range and net rearing groups. The feed/egg ratio in the net rearing group duriug the total period was 3.68, and which was similar （P〉0.05） in the free -range rearing group （3.58）. The feed/egg ratio both in the net and free - range rearing groups was. ex- tremely significantly lower （P 〈 0.01 ） that in the cage rearing group （4.56）. The abnormal egg rate in the net rearing group was 3.21% , which was extremely significantly lower （ P 〈 0.01 ） than that in the cage rearing group （ 5.44% ） and the free - range rearing group （4.12%）, but the abnormal egg rate in the cage rearing group was extremely significantly higher （P 〈 0.01 ） than that in the free -range rea- ring group. The results indicate that the net - rearing method not only does not affect the laying performance of the Shanma duck, and can re- duce feed consumption and replace the traditional methods.
