摘要

目的:本研究旨在确定添加柠檬皮精油(EO)作为饲料添加剂对改变热带荷斯坦奶牛粪便微生物多样性的影响。方法和结果:本研究使用了 12 头泌乳中期的弗里斯兰荷斯坦热带奶牛,其平均产奶量为 6.97 ± 0.77 千克/头/天,体重为 426.23 ± 11.83 千克,变异系数为 6.5%。每头/天使用的柠檬皮环氧乙烷剂量如下:S1=0毫升,S2=2.50毫升,S3=5.00毫升。参数包括粪便微生物门和属的丰度。然后,采用描述性定量分析对数据进行分析。主要成分为柠檬烯的柠檬皮精油在 5 mL/头/天的剂量下增加了固着菌门的相对数量,但减少了杆菌门的数量。在 2.5 毫升/头/天的剂量下,坚固菌门和杆菌门的数量与对照组相对接近。与对照组相比,添加剂量为 2.5 毫升/头/天和 5 毫升/头/天的柠檬皮精油减少了前鞭毛菌门的数量。研究的结论、意义和影响:本研究得出的结论是,5 毫升/头/天的柠檬皮精油剂量会影响具有蛋白水解活性的热带荷斯坦奶牛粪便中普雷沃氏菌的微生物丰度。这项研究通过抑制蛋白水解菌普雷沃特氏菌,对提高牛奶产量产生了影响。

Evaluation of lemon peel essential oil on fecal microbial diversity of tropical Holstein dairy cows
Aims: This study was aimed to determine the effects of adding lemon peel essential oil (EO) as a feed additive to change fecal microbial diversity in tropical Holstein dairy cows. Methodology and results: This study used 12 mid-lactation Friesian Holstein tropical dairy cows with an average milk production of 6.97 ± 0.77 kg/head/day and a body weight of 426.23 ± 11.83 kg, coefficient of variation (CV=6.5%). The doses of lemon peel EO used for each head/day were as follows: S1=0 mL, S2=2.50 mL and S3=5.00 mL. Parameters consisted of an abundance of fecal microbes in phylum and genus levels. Then, the data were analyzed using descriptive quantitative analysis. Lemon peel essential oil with the main component limonene increased the relative population of the Firmicutes phylum at a dose of 5 mL/head/day but decreased the population of the Bacteriodetes phylum. The 2.5 mL/head/day dose has a relatively similar population with controls in Firmicutes and Bacteriodetes phyla. Adding lemon peel essential oil at doses of 2.5 and 5 mL/head/day reduced the population of Prevotellaceae compared to the control. Conclusion, significance and impact of study: This study concluded that a lemon peel EO dose of 5 mL/head/day affects the microbial abundance of Prevotella in the feces of tropical Holstein dairy cows with proteolytic activities. This research impacts increasing milk production due to the inhibition of Prevotella , a proteolytic bacterium.

期刊介绍: The Malaysian Journal of Microbiology (MJM) publishes high quality microbiology research related to the tropics. These include infectious diseases and antimicrobials. In addition, the journal also publishes research works on the application of microbes for the betterment of human society and the environment. The journal welcomes papers on isolation, identification, characterization and application of microbes and microbial products. The MJM is published under the auspices of the Malaysian Society for Microbiology. It serves as a forum for scientific communication among scientists and academics who deal with microbes and microbial products. The journal publishes research articles, short communications and review articles on various novel aspects of microbiology, which include topics related to medical, pharmaceutical, food, agricultural, industry, plant pathology, biotechnology, microbial genetics, environment, soil, water and biodeterioration. The journal aspires to emphasize the important roles played by microbes in our daily life.
