摘 要:本试验旨在探究饲粮中添加不同复方精油(CEO)对肉兔健康状况、生长性能、经济效益的影响,为复方精油在肉兔饲粮中的应用提供数据支持。从60窝33日龄断奶伊拉肉兔中,每窝选择4只健康、体重接近(0.798±0.083)kg的仔兔,以窝为单位随机分成4组;(1)对照组,基础饲粮;(2)试验Ⅰ组,基础饲粮+300 mg/kg CEOⅠ;(3)试验Ⅱ组,基础饲粮+300 mg/kg CEOⅡ;(4)试验Ⅲ组,基础饲粮+300 mg/kg CEOⅢ;每组15个重复,每个重复4只兔,共240只试验兔,试验期共42 d。结果表明:(1)试验期间试验组的腹泻率为1.05%~1.76%,试验组的腹泻率有低于对照组的趋势(P=0.06),试验Ⅱ组的死亡率最低与其他各组差异极显著(P<0.01),且试验组的死亡率均低于对照组。(2)试验全期(1~42 d)试验Ⅰ、Ⅱ、Ⅲ组的日增重极显著高于对照组(P=0.009),分别高9.95%、12.54%和13.71%;试验Ⅰ和Ⅱ组的采食量极显著高于对照组(P<0.001),分别提高了10.42%和12.50%(P<0.001);而各处理组的料重比差异不显著(P=0.187)。(3)各处理组出栏肉兔的利润,精油组的效益均好于对照组,试验Ⅰ、Ⅱ、Ⅲ组的效益分别是对照组的1.85倍、3.81倍和1.83倍。综合来看,以复方精油Ⅱ为最好。The purpose of this experiment was to investigate the effects of different compound essential oils(CEO)on the health status,growth performance and economic benefits of meat rabbits,and provided data support for the application of compound essential oil in meat rabbit diet.From 60 litters of 33-days-old Ira rabbits,4 healthy young rabbits with similar body weight(0.798±0.083)kg were selected from each litter,randomly divided into 4 test groups based on litter;(1)Control group,basic diet;(2)Test group I,basal diet+300 mg/kg CEOⅠ;(3)Test groupⅡ,basal diet+300 mg/kg CEOⅡ;(4)Test groupⅢ,basic diet+300 mg/kg CEOⅢ.Each group had 15 replicates with 4 rabbits per replicate,a total of 240 rabbits were tested for 42 days.The results showed as follows:(1)During the test,the diarrhea rate of the test group was 1.05%~1.76%,and the diarrhea rate of the test group was lower than that of the control group(P=0.06);The mortality of groupⅡwas significantly lower than that of other groups(P<0.01),and the mortality of test groups was lower than that of the control group(P<0.01).(2)The whole period of the test(1~42 days),the daily gain of groupsⅠ,ⅡandⅢwas significantly higher than the control group(P=0.009),which increased by 10.42%,12.50%and 13.71%;The feed intake of test groupsⅠandⅡwas significantly higher than the control group(P<0.001),which increased by 10.42%and 12.50%(P<0.001),but the feed to weight ratio of each test group had no significant difference(P=0.187).(3)The profit of the rabbit in each test group was better than the control group,and the benefit of groupsⅠ,ⅡandⅢwas 1.85 times,3.81 times and 1.83 times of the control group respectively.In summary,compound essential oilⅡwas the best in each test group.
