來自蘇格蘭的科學家農村大學(SRUC)已經成功地從水仙花稱為haemanthamine提取的一種化學物質。他們顯示提取能減少甲烷排放96%但在實驗室,使用一個人造牛的胃。在田間應用程序中,通過飼料,科學家們樂觀的可能減少排放30%的奶牛。作為四年項目的一部分是由資金從英國環境、食品和農村事務部(Defra)和英國創新的£2.8(合3.6美元)的資金接近£1 m工業夥伴,提取將評估在英國幾家商業奶牛場。花力量傑米•紐伯爾德教授SRCU動物科學教授告訴FeedNavigator水仙花的勘探工作進行提取是正在進行的研究的一部分甲烷排放阻滯劑的機構。“我們已經工作了很長時間的合作夥伴植物提取物可能操縱瘤胃和減少甲烷。作為的一部分,我們遇到haemanthamine,加蘭他敏生產的副產品。”Galantamine is used to treat mild to moderate confusion - dementia - related to Alzheimer's disease. "We saw that haemanthamine had beneficial effects in the rumen. We verified that finding in-vitro, using assays, and we showed that haemanthamine can inhibit both methane production and protein degradation.” Daffodil supply chain The Defra backed project is going to test that laboratory-type observation further; there are three parts to it. “Firstly, we need to establish a daffodil supply chain and develop an extraction procedure that is commercially viable. The second phase is working to prove that the extract is safe for both animals and humans. The third phase will involve working with a series of farmer partners to test the additive on four or five dairy farms in England and Wales to show that it works in terms of reducing methane and allowing the farm to feed less supplemental protein,” continued the academic. The project consortium is a combination of scientists, agronomists, and agricultural experts including SRUC, Bangor University, the Centre for Innovation Excellence in Livestock (CIEL), Rumenco and Wynnstay, Grampian Growers and Agroceutical Products Ltd, the Analox Group, Beneve Ltd, and Bioextraction Ltd. "SRUC is doing the rumen screening type work and our colleagues in Bangor have academic expertise in the extraction of bioactives," said Prof Newbold. Grampian Growers, Agroceutical, Bioextractions, Rumenco and Wynnstay will manage the production of the bioactive compound through to the finished feed, while Analox Group will develop on-farm technology for monitoring methane emissions. CIEL will assist with driving knowledge exchange and industry engagement. "Rumenco is the commercial lead and, together with Wynnstay, it will have a key role in marketing the additive," said Prof Newbold. "Livestock farming faces scrutiny in terms of its environmental impact and resource utilisation, particularly when it comes to methane contributions. Through the project, we can work to address these challenges head-on, and find a practical solution for making livestock farming more sustainable," said Annie Williams, business development manager, CIEL. Mode of action SRUC will also be undertaking the initial animal work, to determine the right dose level for the feed additive, and to understand its mode of action. "We know what, we don’t know how.” In addition, the college has an advisory role on the animal trials and will ensure compliance with the relevant environmental regulations as well. "There will be an initial subset of experiments, which will involve 12 cows in quite controlled conditions, and then, as the project rolls on into year three and four, the extract will be tested on partner farms in wider groups of animals." Prof Newbold reckons the final feed addtive would be cost effective to apply on farms given that it is an industrial by-product. "It would probably cost about 5c per animal per day."
