A special feed aimed at the reduction of boar taint will be tested as of this month on a large farm in Eastern Germany. The trial will be happening on a 5,000 sow farm, with a finishing capacity of 60,000 pigs.
一种旨在减少公猪膻味的特殊饲料将于本月在德国东部的一个大型农场进行试验。这项试验将在一个5000头母猪农场进行，出栏能力为60000头。
The approach, called Taintstop, reduces boar taint as in-feed additives and fibres break down skatole inside the pig’s intestines, which effectively means that the liver is freed up for other duties, like the breaking down of the other compound causing boar taint: androstenone.
这种被称为“膻味停”的饲料可以减少公猪膻味，因为饲料添加剂和纤维可以分解猪肠道内的粪臭素，这实际上意味着可以解放肝脏的某些功能，例如分解造成公猪膻味的另一种化合物：雄甾烯酮。

采用这种减少膻味的策略，屠宰线上的公猪胴体最多只有1%有膻味。
A large German retailer has shown interest in the approach, which is produced and marketed by Belgian feed company Dumoulin. The company claims that a maximum of 1% of Taintstop-fed boars on the slaughterline eventually will have boar taint.
一家德国大型零售商对这种由比利时饲料公司Dumoulin生产和销售的饲料产生了兴趣。Dumoulin表示，使用了这种饲料的公猪，最终屠宰时最多只有1%会有膻味。
The trials shall be carried out under the supervision of an independent institute with a total of 2,000 boars.
试验将在一家独立机构的监督下进行，共2000头公猪接受试验。
Trials with various pig breeds
对不同品种猪进行试验
Werner Reuter, head of research at Dumoulin, explained at the recently held livestock event AgriFlanders in Belgium, that the company has carried out 14 trials so far, with various breeds. The company tested the results on offspring of e.g. DanBred, Topigs and PIC sows. Mr Reuter explained that the risk of boar taint is mainly occurring with Duroc genetics.
Dumoulin的研究负责人Werner Reuter在最近举行的比利时畜牧展AgriFlanders上解释说，到目前为止，该公司已进行了14次试验，其中包括各种品种。公司对丹育母猪、Topigs母猪和PIC母猪的后代进行了检测。Reuter先生解释说，公猪膻味的风险主要发生在杜洛克遗传学上。
Mr Reuter said: “There is no such thing as 0% risk. Within the group of boars fed Taintstop there is a maximum of 1% with boar taint,” adding that, even with barrows and gilts tainted carcasses can occur.
Reuter先生表示：“0%的发生率是不可能的。该公司饲喂‘膻味停’的公猪中，最多仍有1%会有膻味”，他还表示，哪怕是阉猪或者后备母猪都可能有膻味。
Worldwide interest for feeding approach
该饲料引起全球关注
Mr Reuter added that the international interest has grown for the strategy since EuroTier, held in November 2018. At the show, Taintstop won a silver medal. In for instance Brazil, Canada, Colombia and Mexico producers have expressed interest in Taintstop to reduce the risk of tainted carcasses.
Reuter先生称，自2018年11月汉诺威国际畜牧展（EuroTier）举办以来，这种饲料引起了越来越多国家养猪企业的关注。“膻味停”当时在展会上赢得了一枚银牌。巴西、加拿大、哥伦比亚及墨西哥等国家的养猪户对“膻味停”表现出浓厚兴趣，以期减少公猪膻味。
In addition, in France, the feed has been tested with boars that would be slaughtered at on average 120 kg liveweight.
另外，在法国，这种饲料已经用将于平均120公斤活重时屠宰的公猪进行了试验。
Additional costs of the feed strategy is about € 3-4. The animal nutrition company has been trying to create a simpler version of the feed concept, aiming to reduce costs. Mr Werner said that that did not prove possible, which effectively means that the components haven’t changed. The company advises to feed the product about 2 weeks prior to slaughter.
这种饲料策略的额外成本约为3-4欧元。Dumoulin一直在尝试创建一个更简单的饲料概念版本，旨在降低成本。但Werner先生表示，事实证明这是不可能的，这实际上意味着配方没有发生变化。该公司建议在屠宰前约2周饲喂该产品。
