摘　　要：为探讨秸秆生物发酵饲料对肉羊生长性能、营养物质消化率与血液生化指标的影响,本试验选择体重在20 kg左右小尾寒羊48只,随机分成3组,即对照组(铡切玉米秸秆)、试验1组(青贮玉米秸秆)和试验2组(玉米秸秆生物饲料)。试验结果表明,平均日增重2组极显著高于对照组(P<0.01),1组显著高于对照组(P<0.05);料重比2组与1组较对照组分别降低26.84%和23.42%(P<0.05)。干物质消化率1组、2组显著高于对照组(P<0.05);粗纤维消化率2组极显著高于对照组(P<0.01),显著高于1组(P<0.05);粗蛋白消化率,2组显著高于对照组及1组(P<0.05)。总蛋白水平2组显著高于对照组(P<0.05);白蛋白水平1组、2组均显著高于对照组(P<0.05);尿素氮水平2组较1组及对照组显著下降(P<0.05)。说明秸秆生物饲料可促进肉羊生长、提高饲料效率,改善肉羊消化吸收功能及免疫水平。To study the straw biological fermentation feed on growth performance and blood indexes in mutton sheep, 48 small tailed han sheep were allocated to three dietary groups as control group （cut corn stalks） ,group 1 （si- lage maize straw） and group 2 （straw biological fermentation feed）. The result showed that the average daily gain in group 2 increased more significantly higher than the control group （P〈0.01）. Group 1 was significantly higher than the control group （P〈0.05）. Feed to gain ratio of group 2 and group 1 reduced 26.84% and 23.42% compared with the control group （P〈0.05）. Dry matter digestibility （P〈0.05） of group 2 was more significantly higher than the con- trol group （P〈0.01）, and digestibility of crude fibre of group 2 was significantly higher than group 1 （P〈0.05）. Di- gestibility of CP of group 2 was significantly higher than group 1 and control group （/~〈0.05）. TP of group 2 was sig- nificantly higher than control group （P〈0.05）. Albumin level of group 1 and group 2 were significantly higher than the control group （P〈0.05）. Nitrogen level of urea of group 2 was depressed compared with group 1 and control group （/~〈0.05）. The results demonstrated that the straw biological fermentation feed promoted the growth of mutton sheep, increased the feed efficiency and improved the digestion and absorption function as well as immune level.
