生物安全高度重視在對豬傳染性病毒IPPE討論   發布日期: 201425

豬流行性腹瀉病毒的情況下  PEDV)的報導,在美國不到一年的時間。就在這個時候,獸醫學到了很多關於這個疾病的,但也有未回答的問題。

“什麼是已知的是這種病毒具有很高的死亡率,高達100%的非常年輕的動物死亡和病毒是非常穩定的,能夠留在一個環境,星期,這可能會導致持續的損失,”博士說:瑪麗授予Battrell,高級生產豬獸醫在墨菲-布朗有限責任公司,在國際集約化畜牧生產的豬肉2014年期間舉行的峰會豬流行性腹瀉病毒圓桌討論國際生產加工博覽會  IPPE)。本次峰會贊助VIV的荷蘭的貿易展覽會組織者。

雖然在沒有一定的傳輸的方法中,很顯然,該病毒是高度傳染性的。

“基本上,底線是你需要鎖定你的農場了。有很多的豬流行性腹瀉病毒可以進入一個農場積極的方式,”授予Battrell說。“我們需要把很多重點的生物安全。”

預安排農場的馬修·特納博士指出,生產恢復緩慢下一個浪潮豬流行性腹瀉病毒的一些原因。雖然PED是辦法傳染性胃腸炎(TGE)類似,PED是更難擺脫,而且生產週期可能會受到影響,只要幾個月。因為豬棚這種高度傳染的病毒量巨大,很難為母豬,以保護他們的年輕人傳遞的免疫力。此外,流產和降低受孕率可以與豬流行性腹瀉病毒爆發相關聯,有時當豬繁殖與呼吸病毒傳播的同時引起的。

在他的演講對美國豬肉行業的全球視野的未來,詹姆斯建伍,荷蘭合作銀行的常務董事,觀察,豬肉是領先的全球消費肉類蛋白質,雞肉趕上和牛肉相當穩定。他還指出,中國是微積分的重要組成部分。這是最大的單一蛋白消費市場和豬肉代表近75%都消耗蛋白質。這些數字可能​​加起來好消息,在美國,它已經從增加全球豬肉需求中受益,特別是如果中國遵循日本模式。

“對於豬肉產業的前景是基於理解的價值鏈,”肯伍德說,使用亞特蘭大的爆炸降雪天氣,提醒聽眾,天氣是一個原因為什麼豬肉價值鏈是不穩定的,“不是為微弱的心臟。

雖然早期預測稱2014年是一年的盈利紀錄,從日元貶值事情 - 這使得美國生產的豬肉更貴 - 對豬流行性腹瀉病毒的傳播可能會影響預測。

從中國的角度來看,馬闖,副秘書長,動物科學協會中國獸醫和合作夥伴,博伊爾傳播有限公司,詳細介紹了一些未來的挑戰和機遇。他分享了牛羊肉價格在中國大幅飆升,使得豬肉的消費者誰渴望更多的蛋白質在他們的飲食更加經濟實惠的選擇。如果牛肉生產不能滿足這種需求,那麼其他來源都會有一個開口,包括豬肉和家禽。對家禽的需求也隨之上漲,儘管它遭到H7N9禽流感爆發的最後一年。還預計豬肉及食用雜碎的進口增長。

Biosecurity highly emphasized at IPPE discussion on contagious pig virus    Release Date: 2014年2月5日
Cases of porcine epidemic diarrhea virus (PEDV) have been reported in the U.S. for less than a year. In this time, veterinarians have learned a lot about the disease but also have unanswered questions.

"What is known is this virus has a high mortality rate-up to 100 percent of very young animals die-and the virus is very stable, capable of remaining in an environment for weeks, which can lead to ongoing losses," said Dr. Mary Battrell, senior production swine veterinarian at Murphy-Brown LLC, at the VIV International Pork Production Summit Porcine Epidemic Diarrhea Virus roundtable discussion held during the 2014 International Production & Processing Expo (IPPE). The summit was sponsored by Dutch-based trade show organizers of VIV.

Although the method of transmission in not certain, it is clear that the virus is highly contagious.

"Basically, the bottom line is you need to lock your farm down. There's a lot of positive ways PEDV can get into a farm," Battrell said. "We need to put a lot of emphasis on biosecurity."

Dr. Matthew Turner of Prestage Farms pointed out that production is slow to recover following a wave of PEDV for a number of reasons. Although PED is similar in ways to transmissible gastroenteritis (TGE), PED is much harder to get rid of, and the production cycle can be affected for as long as several months. Because pigs shed enormous amounts of this highly infectious virus, it is difficult for sows to protect their young by passing on immunity. Also, abortions and reduced conception rates may be associated with a PEDV outbreak, sometimes caused when porcine reproductive and respiratory virus spreads at the same time.

In his presentation on the future of the U.S. pork sector in a global perspective, James Kenwood, managing director of Rabobank International, observed that pork is the leading globally consumed meat protein, with chicken catching up and beef fairly stable. He also noted that China is an important part of that calculus. It is the largest single protein-consuming market, and pork represents nearly 75 percent of all protein consumed. These numbers could add up to good news for the U.S., which has already benefitted from increased global pork demand, particularly if China follows the model of Japan.

"The outlook for the pork sector is based on understanding the value chain," Kenwood said, using Atlanta's blast of snowy weather to remind the audience that weather is one reason why the pork value chain is volatile and "not for the faint of heart."

Although early predictions call for 2014 to be a year of record profitability, anything from devaluation of the yen - which makes U.S. produced pork more expensive - to the spread of the PEDV could affect that forecast.

From a Chinese perspective, Ma Chuang, vice secretary general, Chinese Association of Animal Science and Veterinary Medicine and partner, Boyar Communication Co., detailed some of the challenges and opportunities ahead. He shared that beef and mutton prices in China have soared, making pork a more affordable option for consumers who crave more protein in their diets. If beef production cannot meet this demand, then other sources will have an opening, including pork and poultry. Demand for poultry has also risen, although it was hit by the outbreak of H7N9 bird flu last year. Importation of pork and edible offal is also expected to grow.
