  微评:早在2013年,美国华盛顿州就开启了首个娱乐用大麻合法市场之际,种植者不希望大麻杆、根、叶白白浪费,想出一个"废物利用"的奇招:喂养"大麻猪"。据个别使用大麻的养猪场测验所得,大麻可提高生长猪的上市重。201311月,华盛顿州选民投票通过决议,使该州成为美国率先将娱乐用大麻合法的州之一。科罗拉多州也通过了类似决议。成功的经验总是希望得到无限的复制,扩张,今天我们来看欧洲丹麦的做法。

  RESEARCH: Bioactive ingredients from industrial hemp will be used in new research to optimise the diets for sows and piglets, thus reducing post-weaning diarrhoea, the use of antibiotics and piglet mortality.
  研究:从工业用大麻提取的活性成分可用在新的研究中,优化母猪和仔猪的日粮,从而减少断奶后腹泻,降低抗生素的使用率以及仔猪死亡率。
  The pig industry in Denmark is challenged by high piglet mortality which is very costly for the industry. But now scientists from Aarhus University will be testing a new strategy in an effort to reduce mortality and to enhance animal welfare.
  丹麦的养猪业被仔猪高死亡率所威胁,这是非常昂贵的成本代价。但是现在奥胡斯大学的科学家正在致力于研究新的战略来降低仔猪死亡率,提高动物的福利。
  It is the industrial variety of hemp that scientists and a number of industrial partners are putting their faith into with the aid of a 6.7 million DKK ((8.9 mln欧元) grant from the Green Development and Demonstration Programme under the Ministry of Food, Agriculture and Fisheries.
  这是个工业大麻的项目,科学家和一些工业合作伙伴寄希望于食品,农业和渔业部下属的绿色发展和示范计划的拨款,共670万丹麦克朗(890万欧元)。
  Hemp contains protein, fibre and fatty acids of a very high nutritional value plus some potentially immuno-modulating substances that present a hitherto untapped bioactive resource for pigs.
  大麻含有蛋白质,纤维和脂肪酸,营养价值很高,还有些潜在的免疫调节物质,这些物质是迄今为止尚未开发的猪生物活性源。
  - In the project we will focus on the potential in using protein and oil from industrial hemp as a special feed and feed supplement for piglets and sows. The cold-pressed therapeutic hemp seed oil and protein may help solve the production challenges of post-weaning scours and early mortality due to their unique ingredients, explains project leader and section manager at the Department of Animal Science, Charlotte Lauridsen.
  在此项目中,我们重点研究工业大麻的蛋白和油的潜在利用,这种大麻可作为仔猪和母猪的特殊饲料和饲料添加物。冷榨的治疗大麻籽油和蛋白质可帮助解决断奶后腹泻和早期死亡率的挑战,这是由于它们具有独特的成分,动物科学项目负责人及部门经理Charlotte Lauridsen讲到。
  The rationale for the project is the positive experience from a pig farm where a hemp oil product was added to the diet of piglets and weaners. This led to a marked improvement in piglet survival and it is this improvement that the project participants hope to copy.
  该项目的基本原理是从一个将大麻油产品添加到仔猪和断奶仔猪日粮中的农场所获得的积极经验。正是这种对仔猪死亡率的改善效果,让项目参与者希望能复制这种经验。
  Before the effect of the hemp products can be tested in the project, processes need to be developed to remove THC from hemp (THC = tetrahydrocannabinol - a psychoactive substance that is found only in low concentrations in industrial hemp and is therefore useless for recreational purposes) so that the hemp can be used for animal feed. The project will look at the effect of hemp on piglet survival. This is done by supplementing hemp to the lactation diet for sows, which via the colostrum will provide energy and vitamin E to piglets and raise their concentration of immunoglobulin and thus their resistance to infections. Particularly energy depots and vitamin E levels are low in newborn pigs.
  之前大麻产品的效应也在本项目中进行了测试,需要卡法工艺,从大麻中取出THC(THC=四氢大麻酚,这是一种仅在工业大麻中存在的低水平的精神刺激物质,因此除了休闲娱乐别无它用),这样大麻就能添加到动物饲料中。该项目研究了大麻对仔猪死亡率的影响。他们将大麻添加到母猪的哺乳期日粮中,这样可凭借初乳为仔猪提供能量和维生素E,提升它们的免疫球蛋白的浓度,这样就会提高它们抵抗感染的能力。特别是对于那些能量源和维生素E水平低下的新生仔猪。
  The project will also explore the effect of substances in hemp on post-weaning diarrhoea and the growth potential of piglets.
  该项目还将探索大麻成分对仔猪断奶后腹泻以及生长潜力的影响。
  - Fatty acid composition, protein allocation and the content and composition of fibres are important for intestinal health and immune response in pigs during the critical post-weaning period. The hemp plant contains substances with therapeutic properties that are of interest for the control of inflammation of the intestines due to infection, says Charlotte Lauridsen.
  脂肪酸成分,蛋白质分配和纤维构成对于仔猪刚断奶后的肠道健康和免疫反应是非常重要的因素。大麻植物具有的治疗功效可用于控制肠道由于感染引起的炎症,Charlotte Lauridsen讲到。
  Project participants estimate that the commercial utilisation of hemp products can reduce piglet mortality by 1.5 pigs per litter and that the incidence of post-weaning diarrhoea can likewise be reduced and thus the consumption of antibiotics.
  项目参与者评估了大麻产品的商业应用,它们可使每窝仔猪减少1.5的死亡,而且也会降低断奶后腹泻的发病率,自然也就降低了抗生素的使用。
  - E. coli is the leading cause of diarrhoea in the first few weeks post weaning, and we expect that hemp products can reduce mortality. At the same time, it is estimated that the majority of the antibiotics consumed is used to treat gastrointestinal disorders in pigs, and these disorders are therefore the major causes of the use of antibiotics in pig production, says Charlotte Lauridsen and continues:
  - 大肠杆菌可引起仔猪断奶后头几周发生腹泻,我们预测大麻产品科降低死亡率。与此同时,据估计,大多数抗生素将用来治疗仔猪的胃肠道疾病,这些疾病是养猪业大量使用抗生素的原因,Charlotte Lauridsen补充说。
  - Supplementation with hemp products will hopefully result in fewer outbreaks of post-weaning diarrhoea and will improve the health of the gastrointestinal tract in piglets, which in turn will lead to a reduced need for antibiotic treatment.
  添加大麻产品有望减少断奶后腹泻的爆发,将会改善仔猪的胃肠道健康,反过来也将会降低治疗对抗生素的需求。
  In addition to the expected effects on mortality, post-weaning diarrhoea and animal welfare, the project participants believe the cultivation of hemp also offers environmental benefits since its cultivation does not require pesticides.
  除了对死亡率,断奶后腹泻和动物福利的预期效果,项目参与者认为种植大麻还可提供环境效益,因为它的种植不需要农药。
  The project started on 1 January 2014 and will run until 31 July 2017.
  该项目开始于2014年1月1日,将进行至2017年7月31日。
