摘 要:为探讨喷浆麸皮对蛋鸡生产性能和营养物质表观消化率的影响,试验采用单因子试验设计,选择240日龄海兰灰蛋鸡500只,分为5组,每组5个重复,每个重复20只。Ⅰ-Ⅴ组喷浆麸皮占配方比例为0、0.92%、1.84%、2.76%和3.68%,预试期7 d,试验期为60 d。结果表明:①喷浆麸皮对蛋鸡的产蛋率、平均蛋重、只日产蛋量、料蛋比和软破畸形蛋率无显著影响。与对照组相比,Ⅴ组只日耗料量降低5.48%(P<0.05)。Ⅳ组死淘率比对照组降低87.5%(P<0.05)。②Ⅱ组蛋白表观消化率低于对照组(P<0.05),其余试验组高于对照组(P<0.05)。各试验组钙表观消化率均高于对照组,其中Ⅱ、Ⅲ、Ⅳ组达到显著水平。Ⅲ组和Ⅴ组P表观消化率高于对照组(P<0.05)。③各试验组经济效益均高于对照组。For investigating the effect of corn fiber feed on production performance in laying hens,in this experiment,500 240-days-old laying hens were randomly allotted to 5 treatments,with each treatment represented by 5 replicates of 20 birds each.Ⅰ to V groups experiment diets used 0,0.92%,1.84%,2.76% and 3.68%.Pre-feeding period was 7 days and the experiment lasted 60 days.The results indicated: ① Compared with the control group,there were no significant effect on the egg production rates,average egg weight,day-egg yields,feed conversion ratio and broken(soft) eggshell rates.V group decreased the day-feed intake by 5.48% significantly than the control group(P〈0.05).Ⅳ group decreased the mortality significantly by 87.5% compared with the control group(P〈0.05).② The apparent digestibility of CP of Ⅱ group was lower than the control group(P〈0.05),others were higher than the control group(P〈0.05).All the experiment groups were higher than the control group in the index of Ca,Ⅱ,Ⅲ and Ⅳ experiment groups were effective.The index of P were higher than the control group(P〈0.05).③ Every group increased the economic efficiency.
