摘 要:选取健康、体重差异不显著的产蛋期微山麻鸭800只,自由采食与饮水,常规免疫与饲养管理。以人工模拟的水池为对照组,另设喷淋、深水槽、纯旱养3种旱养模式作为试验组,每组设置5个重复,每个重复40只鸭。试验结果表明:深水槽组日采食量显著高于纯旱养组(P<0.05),其余各组之间所有生产性能指标差异均不显著(P>0.05);不同旱养模式之间蛋形指数与蛋壳强度差异不显著(P>0.05);3个戏水组(水池、喷淋、深水槽)蛋壳厚度均显著高于纯旱养组(P<0.05);喷淋组在所有蛋品质指标中均表现出明显的优势;除纯旱养组外,喷淋组水源利用与污染减排的综合效益最佳。综合生产性能、蛋品质、水质污染等指标,本试验中喷淋组得到了最佳综合效果。800 healthy Weishan Ma ducks whose body weight were non-significant in laying period were selected in the study. Immunization and feed were according to routine. Artificial ponds (AP) served as controls,showing group (SG),deep water tank (DWT),only drink water (ODW) were experiment groups,every group was divided into 5 replicates of 40 ducks. Results showed that,DWT daily feed intakes improved remarkably compared with ODW (P0.05),all the other performance were not significant (P0.05);egg shape index and shell strength among all the groups were not significant. Shell thickness in other three groups improved remarkably compared with ODW (P0.05),SG achieved a distinctadvantage over the others on egg quality. Besides DWT,SG were the best choose on water utilization and environment benefit. Considering performance,egg quality and water pollution,SG were the best choose in this trial.
