摘　　要：本试验主要研究以平菇菌糠部分替代全株青贮玉米对育肥期肉用山羊生长性能、表观消化率及屠宰性能的影响。试验选取体重相近(15.46±1.24)kg、2月龄的健康青山羊60只,采取单因素随机分组试验设计,按照添加平菇菌糠替代全株青贮玉米的不同比例将试验羊分成5个组,分别为对照组饲喂基础日粮,不添加平菇菌糠、5%组饲喂添加5%平菇菌糠的基础饲粮、10%组饲喂添加10%平菇菌糠的基础日粮、15%组饲喂添加15%平菇菌糠的基础日粮、20%组饲喂添加20%平菇菌糠的基础日粮,每组12只,每组3个重复,每个重复4只羊。预试期7 d,正试期90 d。结果显示,在平均日增重指标方面,1~30 d,20%组显著高于对照组和50%组(P<0.05);31~60 d,5%组显著高于15%、20%组(P<0.05);60~90 d,15%组、20%组显著高于对照组、5%组、10%组(P<0.05);1~90 d,15%组、20%组显著高于对照组和5%组(P<0.05)。各组干物质采食量无差异显著性(是无差异显著性还是无显著差异性?),但有升高的趋势;在料重比指标方面,1~30 d,20%组显著低于对照组和5%组(P<0.05),31~60 d,15%组、20%组显著高于5%组(P<0.05);1~90 d,20%组显著低于对照组和5%组(P<0.05)。20%组干物质、有机物和粗蛋白质表观消化率高于其它各组,显著高于5%组(P<0.05)。20%组屠宰率高于其它各组,显著高于对照组(P<0.05)。综上可见,在本试验条件下,在日粮中添加平菇菌糠替代青贮玉米秸秆可以改善育肥期肉用山羊生产性能、提高营养物质表观消化率及屠宰率,综合分析比较,以添加20%的平菇菌糠效果最佳,切实可行。In order to provide reference for expanding forage sources and improving the utilization rate of silage corn stalks,this experiment studied the effects of Pleurotus ostreatus fungus chaff partially replacing whole-plant silage corn on growth performance,apparent digestibility and slaughter performance of meat goats in fattening period.Sixty healthy Green goats with similar weight of(15.46±1.24)kg and 2 months old were selected,and the single-factor randomized grouping experiment design was adopted.According to different proportions of adding Pleurotus ostreatus fungus chaff instead of whole-plant silage corn,the experimental goats were divided into five groups,and the control group was fed with basic diet withno Pleurotus ostreatus chaff was added,5%group was fed with basal diet with 5%Pleurotus ostreatus chaff,10%group was fed with basal diet with 10%Pleurotus ostreatus chaff,15%group was fed with basal diet with 15%Pleurotus ostreatus chaff,and 20%group was fed with basal diet with 20%Pleurotus ostreatus chaff,with 12 animals in each group and 3 sheep in each replicate.The advanced experiment period is 7 days,and the formal experiment period is 90 days.The results showed that the average daily gain index of 20%group was significantly higher than that of control group and 50%group from 1 to 30 days(P<0.05).From 31 to 60 days,5%group was significantly higher than 15%and 20%groups(P<0.05).From 60 to 90 days,the 15%group and 20%group were significantly higher than those of the control groups,5%group and 10%group(P<0.05).From 1 to 90 days,the 15%group and 20%group were significantly higher than the control group and 5%group(P<0.05).There was no significant difference in dry matter intake among each group,but there was an increasing trend.In terms of the index of feedto gain ratio,the 20%group was significantly lower than the control group and the 5%group from 1 to 30 days(P<0.05),and the 15%group and the 20%group were significantly higher than the 5%group from 31 to 60 days(P<0.05).From 1 to 90 days,the 20%group wa
