摘　　要：试验旨在研究日粮中添加不同水平甜菜粕对焉耆马营养物质消化代谢的影响。选取运动成绩、体重、年龄和体尺相近的焉耆马12匹,随机分为3组,每组4匹。对照组、试验Ⅰ组和试验Ⅱ组在饲喂相同的基础日粮和粗饲料(燕麦秸)的条件下分别补饲0、0.6和1.2kg/d甜菜粕。试验期20d,其中预试期15d,正试期5d。结果表明,与对照组相比,试验Ⅱ组焉耆马对有机物、NDF、ADF的消化量和对日粮NDF、ADF的表观消化率均有极显著提高(P<0.01),对粗蛋白质、钙的消化量和对有机物的表观消化率影响差异显著(P<0.05);试验Ⅰ组焉耆马对NDF和ADF的消化量分别增加了8.19%、9.43%,均达到了显著水平(P<0.05),而对有机物、粗蛋白质、钙的消化量和表观消化率均差异不显著(P>0.05);试验Ⅱ组焉耆马对有机物、NDF和ADF的消化量和表观消化率与试验Ⅰ组相比,均达到了显著或极显著水平(P<0.05;P<0.01),但对粗蛋白质和钙的消化量和表观消化率影响差异不显著(P>0.05)。试验Ⅱ组焉耆马的消化能与对照组和试验Ⅰ组相比分别提高14.92%(P<0.01)和11.23%(P<0.01),而试验Ⅰ组与对照组相比差异不显著(P>0.05);对代谢能而言,试验Ⅱ组比对照组和试验Ⅰ组分别提高11.73%(P>0.05)和14.83%(P<0.05)。因此,日粮中添加1.2kg/d的甜菜粕,可显著提高焉耆马对日粮有机物和粗蛋白质的消化量,极显著提高NDF和ADF的表观消化量(率)及消化能,可明显改善焉耆马对营养物质的利用率。This experiment was conducted to study the effects of supplemental different levels of sugar beet pulp on the nutrients of digestion and metabolism in Yanqi horse.12 Yanqi horses were randomly divided into three groups according to performance,body weight,body measurement and age.The groups were referred to as the control group,group Ⅰ and group Ⅱ,each group with 4Yanqi horses.Yanqi horses in the control group,group Ⅰ and group Ⅱ were supplied with 0,0.6,1.2kg/d of sugar beet pulp on the condition of feeding the same basal diet and roughage（oatstraw）.The total duration of the experiment was 20 days,the first 15 days of the experiment was the preliminary period,and the formal experiment lasted for 5days.The results showed that compared with the control group,the apparent digestibility of OM,NDF,ADF and digestibility amount of NDF,ADF in groupⅡ was extremely significantly improved（P〈0.01）,the digestibility amount of crude protein,calcium and the apparent digestibility of OM in group Ⅱ was significant difference（P〈0.05）;The digestibility amount of NDF,ADF of group Ⅰ was increased by8.19%（P〈0.05）and 9.43%（P〈0.05）,respectively,and the apparent digestibility（amount）of OM,crude protein,calcium were no significant difference（P〉0.05）.Compared with groupⅠ,the apparent digestibility（amount）of OM,NDF,ADF of groupⅡ were significantly or extremely significant difference（P〈0.05;P〈0.01）,but the apparent digestibility（amount）of crude protein,calcium were no significant difference（P〉0.05）.Compared with the control group and group Ⅰ,the digestible engergy of group Ⅱ was increased by 14.92%（P〈0.01）and 11.23%（P〈0.01）,but no significant difference was observed between group Ⅰ and control group（P〉0.05）;The metabolic engergy of group Ⅱ was increased by 11.73%（P〈0.05）and 14.83%（P〈0.05）,respectively.Therefore,the digestion amount of OM,CP of Yanqi horse and the digestion amount and the apparent digestibility of NDF,ADF could
