摘　　要：文章旨在探究日粮中添加不同比例发酵豆渣对育肥猪生长性能、养分表观消化率和血清生化指标的影响。试验将100头生长状况和体态良好的90日龄杂交育肥猪随机分为4组,每组5个重复,每个重复5头。试验日粮分别使用0%、3%、6%和9%的发酵豆渣替代基础日粮中的豆渣。试验为期100d,其中预试验7d,正式试验93d。试验结果表明,在初始体重无显著差异的前提下(P> 0.05),与对照组相比,使用6%和9%的发酵豆渣替代豆渣,育肥猪的终末体重分别显著提高3.87%和4.58%(P <0.05);平均日增重分别显著提高7.5%和8.6%(P <0.05);料重比分别显著降低5.2%和6.5%(P <0.05)。此外,使用发酵豆渣替代豆渣对育肥猪平均日采食量无显著影响(P> 0.05)。与对照组相比,使用6%和9%的发酵豆渣替代豆渣可显著提高育肥猪粗蛋白质和粗脂肪表观消化率(P <0.05);此外,使用发酵豆渣替代豆渣对育肥猪干物质、能量和粗灰分的表观消化率无显著影响(P> 0.05)。使用6%和9%的发酵豆渣替代豆渣可显著提高育肥猪血清总蛋白和白蛋白含量(P <0.05);与对照组相比,使用3%~9%的发酵豆渣替代豆渣显著降低育肥猪血清尿素氮含量(P <0.05);此外,使用发酵豆渣替代豆渣对育肥猪血清GLB含量以及AST、ALT和ALP活性均无显著影响(P> 0.05)。综上所述,使用发酵豆渣替代豆渣可通过提高育肥猪养分表观消化率和改善血清生化指标促进育肥猪生长发育。The article aimed to explore the effects of adding different proportions of fermented soybean residue to the diet on the growth performance,nutrient apparent digestibility,and serum biochemical indicators of fattening pigs.10090 day old hybrid fattening pigs with good growth and physical condition were randomly divided into 4 groups,with 5 replicates in each group and 5 pigs in each replicate.The experimental diet used 0%,3%,6%,and 9%fermented soybean residue instead of soybean residue in the base diet.The experiment lasted for 100 days,with 7 days of pre testing and 93 days of formal testing.The experimental results showed that,under the premise of no significant difference in initial body weight(P>0.05),compared with the control group,using 6%and 9%fermented soybean residue instead of soybean residue significantly increased the final body weight of fattening pigs by 3.87%and 4.58%,respectively(P<0.05);The average daily weight gain significantly increased by 7.5%and 8.6%,respectively(P<0.05);The material to weight ratio significantly decreased by 5.2%and 6.5%,respectively(P<0.05).In addition,the use of fermented soybean residue instead of soybean residue had no significant effect on the average daily feed intake of fattening pigs(P>0.05).Compared with the control group,using 6%and 9%fermented soybean residue instead of soybean residue significantly improved the apparent digestibility of crude protein and crude fat in fattening pigs(P<0.05);In addition,the use of fermented soybean residue instead of soybean residue had no significant effect on the apparent digestibility of dry matter,energy,and crude ash in fattening pigs(P>0.05).Replacing soybean residue with 6%and 9%fermented soybean residue can significantly increase the total serum protein and albumin content of fattening pigs(P<0.05);Compared with the control group,using 3%to 9%fermented soybean residue instead of soybean residue significantly reduced the serum urea nitrogen content of fattening pigs(P<0.05);In addition,the use of fermented soybean residue i
