    養豬新幫手:3D技術可有效減少咬尾,提高生豬福利

    A high-tech system involving 3D cameras could help swine farmers spot the early warning signs of tail biting in pigs, research in the United Kingdom has revealed.

    英國的一項研究顯示,一個包含3D攝像機的高科技係統可以幫助養豬戶發現豬咬尾巴的早期預警信號。

    Tail biting is a health and welfare concern in affected pigs and a significant economic concern for industry, leading to reduced weight gain, culling and carcass condemnation. Research by Scotland’s Rural College (SRUC) has found pigs hold their tails down against their body when tail biting is about to begin.

    對於受影響的豬來說,咬尾是一個健康和福利問題,也是一個重大的工業經濟問題,會導致體重增加減少,影響宰殺和屠宰評定。蘇格蘭農村學院(SRUC)的一項研究發現,當咬尾巴即將開始時,豬會把尾巴緊貼在身上。

    Research measuring whether pig tails were up

    測量豬尾巴是否豎起的研究

    In experiments, researchers used 3-dimensional cameras, placed above feeders, to automatically measure whether their tails were up and curly, or held down.

    在實驗中,研究人員使用放置在喂食器上方的三維攝像機,自動測量它們的尾巴是向上卷曲還是向下彎曲。

    The study was carried out using 23 groups of weaner-grower pigs which were regularly scored for any signs of tail injury. The animals were closely monitored and tail biting was stopped as soon as an outbreak was detected.

    這項研究使用了23組斷奶育肥豬,觀察這些豬的尾巴任何受傷的跡象,定期進行評分。這些豬受到密切監測,一旦發現咬尾現象,就立即進行幹預。

    The study, which has been published in the scientific journal Plos One, successfully enabled scientists to automatically measure tail posture and proved it can act as an early warning sign of tail biting.

    這項研究發表在科學雜誌Plos One上,得益於此,科學家能夠自動測量尾部姿勢,並證明它可以作為咬尾的早期預警信號。

    使用3D相機可以更快發現豬咬尾行為

    Lead author Rick D’Eath from SRUC said: “This research has achieved everything we hoped for. The challenge for us now is to develop this promising technology into a robust on-farm early warning system that works on any pig farm.

    來自SRUC的主要作者Rick D'Eath說:這項研究已經實現了dafabet888平台所希望的一切。現在dafabet888平台麵臨的挑戰是將這種前景光明的技術發展成一個強大的、適用於任何養豬場的農場預警係統。

    Collecting data from more diverse pig farms

    收集更多不同豬場的數據

    This ‘proof of concept’will now be developed in a follow-on Innovate UK-funded project called ‘TailTech’. The project will collect data from more diverse pig farms and develop and test a prototype early warning system.

    這個概念證明現在將在英國資助的創新項目'TailTech'中開發。該項目將收集來自更多不同養豬場的數據,並開發和測試原型預警係統。

    Dave Stephenson, head of pig and poultry at Harbro –one of the research partners, said: “TailTech is another example of a key initiative from the British pig industry designed to drive higher welfare standards on farm.

    研究合作夥伴之一Harbro的豬和家禽主管Dave Stephenson說:“TailTech是英國養豬業關鍵計劃的另一個例子,旨在提高農場的福利標準。

    Tail biting impacts pig welfare

    咬尾影響生豬福利

    Grant Walling, director of science and technology at JSR Genetics –another research partner, added: “We recognise that tail biting impacts on animal welfare, farm productivity and pork quality. Any tool that can help reduce or eradicate the problem is of benefit to the whole supply chain.

    另一位研究合作夥伴JSR Genetics的科學和技術主管Grant Walling補充說:dafabet888平台認識到咬尾對動物福利、農業生產力和豬肉質量的影響。任何有助於減少或消除咬尾問題的工具都有利於整個供應鏈。

    “This technology has the potential to predict future victims so offers opportunities to update and include information within our selection strategies to reduce the incidence of tail-biting in future generations.

    這項技術可能可以對即將受傷的豬進行預判,因此有機會在dafabet888平台的選擇策略中更新並包含這個信息,以減少後代咬尾的發生率。

    Tail biting in pigs is multi-factorial

    豬咬尾由多因素造成

    Outbreaks of tail biting, an abnormal behaviour, have no single cause –there are a number of contributory factors that could include elements of the pig’s genetics, nutrition, environment and management. Outbreaks can occur unpredictably and quickly spread.

    咬尾這種異常行為的爆發,其原因不是單一的- 有許多促成因素,可能包括豬的遺傳、營養、環境和管理等元素。這種爆發可能無法預測且傳播迅速。

    Tail docking of piglets is partly effective at reducing tail biting in later life, but is seen as an undesirable mutilation and its routine use is banned in the EU. Tail biting results in pain and sickness for bitten pigs and severe economic losses for farmers as infection through tail wounds results in abattoir condemnation of meat.

    斷尾可以在一定程度上可以減少後續咬尾巴的行為,但被認為是一種不受歡迎的殘害行為,在歐盟,這種做法是被禁止的。咬尾巴會給被咬的豬帶來痛苦和疾病,給農民帶來嚴重的經濟損失,因為通過尾巴傷口感染會導致屠宰場對肉類的評定下降。

    This condemnation alone can cost a producer up to 1% of the carcass value and a loss for the processor of 1% of saleable carcass from the pig. There are also unquantified on-farm costs as a result of the increased labour and veterinary treatments resulting from an outbreak.

    僅這種譴責就可能使生產者的損失高達胴體價值的1%,並使加工者損失1%的生豬可用胴體。由於咬尾導致勞動力和獸醫治療成本增加,農場成本也無法量化。

    Research partners

    研究合作夥伴

    The research was the result of a collaboration between SRUC animal behaviour and welfare experts, Scottish farm technology company Innovent Technology and pig supply chain partners including feed company Harbro and Sainsbury’s supermarkets, and the Agricultural Engineering Precision Innovation Centre.

    這項研究是SRUC動物行為和福利專家、蘇格蘭農業科技公司Innovent technology、飼料公司HarbroSainsbury 's超市等豬供應鏈合作夥伴以及農業工程精密創新中心合作的結果。

    As part of the next phase of reasearch the consortium of partners will be strengthened with the addition of pig breeders JSR Genetics, engineers David Ritchie, pig vets Garth Pig Practice and farmers’co-operative Scottish Pig Producers.

    作為下一階段研究的一部分,該合作夥伴聯盟將得到加強,增加了種豬企業JSR Genetics、工程師(David Ritchie、豬獸醫Garth pig Practice和蘇格蘭農民合作社。
