| 摘 要： | 【目的】研究发酵底物精粗比为7∶3时不同剂量薰衣草精油对体外瘤胃发酵及甲烷产量的影响。【方法】以5只装有永久性瘤胃瘘管的哈萨克公羊为试验动物,采用瘤胃体外培养方法,设对照组和薰衣草精油添加量为100、150、250μL/L的试验组,每个处理三个重复。【结果】薰衣草精油添加量为150和250μL/L体外培养24 h时降低甲烷产浓度分别为9.72%和24.23%(P<0.05);添加不同剂量薰衣草精油显著提高累计产气量、TVFA、乙酸摩尔比例和NH3-N浓度(P<0.05),降低戊酸、丁酸和BCVFA摩尔比例(P<0.05)。【结论】适当剂量的薰衣草精油对甲烷产生有抑制作用。

| Abstract: | 【Objective】 A series of in vitro studies were performed to evaluate the effects of lavender essential oil on rumen fermentation and methane emission with a 7:3 concentrate: forage diet was used as substrate.【Method】Five Kazakh sheep fitted with rumen cannulae were used as donors of rumen fluid.Treatment s were consisted of control group(0) versus three levels of lavender essential oil(100,150,250 μL/L),and 3 times were repeated for per group.【Result】Methane production was dec reased by 9.72% and 24.23%(P<0.01),at supplementation of 150 and 250 μL/L levels of lavender essential oil.Addition of different levels of lavend er essential oil could significantly increased the total gas production,TVFA,acetic acid proportion an d ammonia-N production(P<0.05);and decreased valerate,butyra te and BCVF A proportion(P<0.05).【Conclusion】The results indicated that addi tion of lavender essential oil at a proper level could inhibit methanogenesis. |
