摘　　要：为探究不同豆秸长度对12月龄德州公驴生长性能的影响,并结合经济效益得出最适豆秸长度。试验选取12月龄健康、体重接近的德州公驴21头,随机分为3个处理,每个处理7个重复,3个处理豆秸长度分别为1、2 cm和4 cm。试验结果表明,与1 cm和4 cm组相比,2 cm组试验结束重分别提高2.4%和1.6%,差异显著(P<0.05);平均日增重分别提高38.2%和20.0%,差异不显著(P>0.05);料重比分别降低28.7%和19.3%,差异不显著(P>0.05),毛利润分别提高24.35%和34.76%。综合生长性能、饲草的适口性及经济效益确定,德州公驴采食最适豆秸长度为2 cm。The aim of this study was to investigate the effects of length of soybean stalk on growth performance of Dezhou male donkey,and got the optimum length of soybean straw combined with economic benefits.Twenty-one male donkeys aged 12 months were grouped in three treatments with 7 replicates according to weight.The length of three soybean stalks were 1 cm,2 cm and 4 cm,respectively.Growth performance data were collected during the test.The final weight of 2 cm group significantly higher than other groups(P<0.05).Compared with 1 cm group and 4 cm group,the final weight of2 cm group increased by 2.4%and 1.6%.And there were no significant effect on other indexes(P>0.05).Compared with 1 cm group and 4 cm group,the average daily gain of 2 cm group increased by38.2%and 20.0%,and the feed to weight ratio decreased by 28.7%and 19.3%,and the gross profit was 24.35%and 34.76%higher than other groups,respectively.Comprehensive growth performance,forage palatability and economic benefits,the optimum length of soybean straw for donkey was 2 cm.
