摘要本试验旨在研究饲粮中添加枯草芽孢杆菌和复合酶制剂对獭兔生长性能、养分表观消化率、屠宰性能、免疫器官指数及毛皮质量的影响。采用单因子设计，选取体重相近的健康42日龄獭兔126只，随机分为3组，每组42个重复，每个重复1只兔。对照组饲喂基础饲粮+300 mg/kg金霉素，试验Ⅰ组饲喂基础饲粮+200 mg/kg枯草芽孢杆菌＋200 mg/kg复合酶制剂，试验Ⅱ组饲喂基础饲粮+400 mg/kg枯草芽孢杆菌＋400 mg/kg复合酶制剂。预试期5 d，正试期41 d。结果表明：1）各组之间獭兔的末重、平均日采食量、平均日增重、料重比、腹泻率和死亡率无显著差异（P>0.05），腹泻率和死亡率均以试验Ⅰ组最低。2）对照组獭兔的粗纤维表观消化率极显著高于试验Ⅱ组（P<0.05），对照组和试验Ⅱ组獭兔的钙表观消化率极显著高于试验Ⅰ组（P<0.01）。各组之间獭兔的干物质、粗蛋白质、粗灰分、磷、中性洗涤纤维和酸性洗涤纤维表观消化率无显著差异（P>0.05）。3）各组之间獭兔的宰前活重、胴体重、半净膛率和全净膛率无显著差异（P>0.05）。4）各组之间獭兔的胸腺指数、脾脏指数和圆小囊指数无显著差异（P>0.05）。5）对照组和试验Ⅰ组獭兔的臀部被毛密度极显著高于试验Ⅱ组（P<0.01），对照组和试验Ⅰ组獭兔的肩部被毛密度显著高于试验Ⅱ组（P<0.05）；对照组獭兔的腹部被毛密度极显著低于试验Ⅰ组和试验Ⅱ组（P<0.01），试验Ⅰ组极显著低于试验Ⅱ组（P<0.01）。对照组獭兔的臀部皮张厚度极显著低于试验Ⅱ组（P<0.01）。由此可见，饲粮中添加枯草芽孢杆菌和复合酶制剂对獭兔生长性能、屠宰性能、免疫器官指数无显著影响，对粗纤维和钙表观消化率及被毛密度、臀部皮张厚度有显著影响。综合考虑以上指标，獭兔饲粮中添加200 mg/kg枯草芽孢杆菌＋200 mg/kg复合酶制剂效果较好。

Abstract：This experiment was conducted to study the effects of dietary Bacillus subtilis and complex enzyme preparation on growth performance, nutrient apparent digestibilities, slaughter performance, immune organ indexes and fur quality of Rex rabbits. A single factor design was adopted, a total of 126 healthy 42-day-old Rex rabbits with similar body weight were randomly divided into 3 groups with 42 replicates per group and 1 rabbit per replicate. Rabbits in the control group were fed a basal diet+300 mg/kg aureomycin, rabbits in the experimental group Ⅰ were fed a basal diet+200 mg/kg Bacillus subtilis+200 mg/kg complex enzyme preparation, and rabbits in the experimental group Ⅱ were fed a basal diet+400 mg/kg Bacillus subtilis+400 mg/kg complex enzyme preparation. The pre-experimental period lasted for 5 days, and the experimental period lasted for 41 days. The results showed as follows: 1) there were no significant effects on the final weight, average daily feed intake, average daily gain, feed to gain ratio, diarrhea rate and mortality rate of Rex rabbits among all groups (P>0.05), and the diarrhea rate and mortality rate were the lowest in experimental group Ⅰ. 2) The crude fiber apparent digestibility of Rex rabbits of control group was significantly higher than that of experimental group Ⅱ (P<0.01), and the calcium apparent digestibility of Rex rabbits of control group and experimental group Ⅱ was significantly higher than that of experimental group Ⅰ (P<0.01). There were no significant effects on the apparent digestibilities of dry matter, crude protein, crude ash, phosphorus, neutral detergent fiber and acid detergent fiber of Rex rabbits among all groups (P>0.05). 3) There were no significant effects on the live weight before slaughter, carcass weight, semi-eviscerated ratio and eviscerated ratio of Rex rabbits among all groups (P>0.05). 4) There were no significant effects on the thymus index, spleen index and sacculus rotundus index of Rex rabbits among all groups (P>0.05). 5) The hair density in buttocks of Rex rabbits of control group and experimental group Ⅰ was significantly higher than that of experimental group Ⅱ (P<0.01), the hair density in shoulder of Rex rabbits of control group and experimental group Ⅰ was significantly higher than that of experimental group Ⅱ (P<0.05); the hair density in belly of Rex rabbits of control group was significantly lower than that of experimental group Ⅰ and experimental group Ⅱ (P<0.01), and experimental group Ⅰ was significantly lower than experimental group Ⅱ (P<0.01). The pelt thickness in buttocks of Rex rabbits of control group was significantly lower than that of experimental group Ⅱ (P<0.01). In conclusion, dietary Bacillus subtilis and complex enzyme preparation have no significant effects on growth performance, slaughter performance and immune organ indexes of Rex rabbits, but have significant effects on apparent digestibilities of crude fiber and calcium and hair density and pelt thickness in buttocks. Considering the above indices, dietary supplemented 200 mg/kg Bacillus subtilis+200 mg/kg complex enzyme preparation for Rex rabbits has better effects.
