摘　　要：试验通过饲养试验旨在研究牛至油对绵羊生产性能和CH4排放的影响。试验选用20只平均体重为(32.16±4.02) kg的东北细毛羊(Northeast finewool sheep)×美利奴(Merino)杂交的公绵羊,随机分为4组,选用单因素完全随机试验设计,每组5只,对照组饲喂基础饲粮,试验组分别饲喂基础饲粮中添加0.015%、0.030%和0.045%牛至油的试验饲粮。试验持续70 d,其中预试期10 d,正试期60 d,测定绵羊的生长性能、血清生化指标和CH4产量。结果表明:①添加0.015%牛至油组绵羊的干物质采食量(dry matter intake, DMI)、平均日增重(average daily gain, ADG)和饲料转化效率(feed conversion efficiency, FCE)均显著高于对照组(P<0.05),其余各处理组间差异不显著(P>0.05);②各处理组绵羊的血清生化指标和甲烷(methane,CH4)产量均未出现显著差异(P>0.05)。由此可知,绵羊饲粮中添加0.015%牛至油可提高绵羊生长性能,但对血清生化指标和CH4产量无显著影响。The aim of this study was to study the effects of oregano oil on performance and methane production of sheep. Twenty healthy sheep [Northeast fineaool sheep×Merino, average weight was(32.16±4.02) kg] were randomly divided into 4 groups. Sheep in different groups were fed basal diets supplemented with 0, 0.015%, 0.030% and 0.045% oregano oil, respectively. The experiment lasted for 70 days, including 10 days acclimation and 60 days experimentation. The growth performance,blood biochemical indicators and methane production of the sheep were measured. The results showed that: ① compared with control group, adding 0.015% oregano oil significantly increased dry matter intake, average daily gain and feed conversion efficiency(P<0.05);② There were no significant differences on blood biochemical indicators and methane production(P>0.05). In conclusion, methane production of sheep was not affected by oregano oil, however, adding 0.015% oregano oil could boost the growth.
