选用360只番鸭,随机分成4组,分别饲喂玉米、稻谷替代玉米和添加二种不同预混料的日粮,四个试验组(1、2、3和4组)的饲料组成分别是:基础日粮+65%玉米+预混料Ⅰ;基础日粮+26%玉米+39%稻谷+预混料Ⅰ;基础日粮+26%玉米+39%稻谷+预混料Ⅱ与基础日粮+65%稻谷+预混料Ⅱ.研究饲料的各种营养成分对番鸭生长性能、消化代谢的影响及其排泄物对环境的影响.结果表明:稻谷部分或全部替代玉米,同时添加自配预混料(Ⅱ),对肉鸭生长速度、饲料报酬没有明显(P>0.05)的影响;但能显著提高营养物质的消化率,可提高蛋白质的吸收率13.09%和17.14%,必需氨基酸的消化率提高3.82%(3组与2组比);磷的存留率分别提高1 580.47% ...

In order to examine the effect of paddy grains as a replacement of corn on the growth and metabolism of duck,an experiment was carried out with 360 ducks which were randomly allocated into 4 groups,and fed with diet 1 (basal diet+65% corn+premix Ⅰ),diet 2(basal diet+26% corn+39% paddy grain +premix Ⅰ),diet 3 (basal diet+26%Corn+39% paddy grain+premix Ⅱ)and diet 4(basal diet+65% paddy grain+premixⅡ),respectively.Significant differences were not observed in the growth of the ducks,and nor in the feed conversion among the four groups.However,t...
