A new study, underwritten by the US Pork Checkoff and conducted by Iowa State University, estimates that porcine reproductive and respiratory syndrome (PRRS) continues to be a major drag on the US pork industry – costing the pork industry $664 million per year.
This translates into $1.8 million per day or $114.71 per sow annually. The previous economic study in 2005 calculated PRRS losses at $560 million annually.
National Pork Board president Everett Forkner, said, "This Checkoff-funded work offers producers, veterinarians and every part of the pork chain a new and valuable insight into the economic impact of PRRS and underscores why we’ve leveraged domestic and international government funds to offer producers tools for regional control of this virus."
The 2011 study differed most significantly from the 2005 study in the allocation of losses between the breeding and the growing pig herds. Specifically, losses in the growing pig herd accounted for 88% of the total cost of PRRS in the 2005 study compared with 55% in the current analysis.
Differences
Iowa State University veterinarian Derald Holtkamp and agricultural economist Jim Kliebenstein collaborated on the study with others in academia, swine veterinarians in private practice and the USDA. They found that differences between the 2005 and the 2011 studies may be attributed to several key factors, including changes in the prevalence of PRRS virus and incidence of outbreaks, production and animal health management practices, inflation (accounts for 40% of the increase) and other pathogens that have emerged since 2005, such as porcine circovirus.
The report summary stated, "Since the 2005 study, pig production and health strategies have evolved, PRRS virus control/elimination strategies have improved and structural adjustments have occurred in the industry. Because of these developments, it was reasonable to question whether the incidence, severity and/or impact of PRRS outbreaks on pig health and productivity in the US herd may have changed since the 2005 study was conducted."
New study
The new study collected much of its data from cooperating producers and veterinarians across the United States in late 2010. While not benchmarked in 2005, additional PRRS-related costs that producers must contend with, such as veterinary and biosecurity measures, were collected in this study. Researchers found these costs added $477.79 million annually to total PRRS costs, putting the cumulative cost of the disease at more than $1 billion per year when added to production-related losses.
Based upon a survey of swine veterinarians from across the United States, the study’s researchers were able to estimate additional PRRS statistics. They found that 28% of sows and gilts used for breeding in the United States were PRRS virus-free and 60% of weaned pigs were PRRS-negative at placement.
Outbreaks
"This study also confirmed conventional wisdom that says outbreaks in PRRS virus-free herds are more severe than outbreaks in PRRS virus-infected herds," Holtkamp said. "When comparing elimination methods, we found that the time required for herds to provide a return on investment was still relatively short with herd closure and rollover. However, we found that complete depopulation/repopulation appears to make economic sense only if there are other reasons to depopulate the herd or for high-value genetics herds."
According to Lisa Becton, Checkoff’s director of swine health, the complete Checkoff-funded research study on PRRS will serve as a valuable resource for producers, veterinarians and the entire industry for years to come as more of its data is analyzed. She said the full report is expected to be available in coming months and will be available on pork.org.

Massive pig deaths in Myanmar linked to bacteria rather than PRRS
//07 Jun 2011
Several sources in Myanmar indicate that an unidentified bacterial pig illness has ravaged hundreds of pigs across the country, where PRRS has also been prevalent for some months now.
Since May 2011, pigs on farms and in small-scale household farming operations in Insein, Hlaingthayar and Hlegu townships have died. Initially Porcine Reproductive and Respiratory Syndrome (PRRS) was suspected, as the disease has been ravaging Myanmar since mid-February.
Bacteria
Tests indicated, however, that these farms were infected with bacteria, but the exact cause is unknown.
"According to laboratory results, they were not infected by blue ear pig disease (= PRRS, ed.). They were infected by a bacterium," Dr Soe Win, head of the Rangoon Region Animal Husbandry and Veterinarian Department, told the India-based Mizzima website.
Cats, dogs, cows
The ‘Democratic Voice of Burma’ reported that cats, dogs and cows were also succumbing to illness in alarming numbers, and carcasses were being spotted on the sides of streets. This information, however, has so far not been confirmed from any official veterinary source.
As a consequence of the outbreaks, farmers have been known to slaughter pigs at the first sign of disease and sell them - sparking concern among meat eaters. Prices of pork on the local markets are said to have already been lower than usually due to the PRRS outbreaks.

Myanmar reports outbreaks of PRRS in Naypyidaw region
//28 Apr 2011
An outbreak of porcine reproductive and respiratory syndrome (PRRS) was reported in Naypyidaw District in early April, according to the Myanmar Animal Husbandry and Veterinary Department.
Independent press agency Mizzima News, ran by Myanmar journalists located in Thailand and India, report that the Naypyidaw District Animal Husbandry and Veterinary Department is educating the public about the disease, which causes reproductive failure in breeding stock and respiratory tract illness in pigs.
On April 7, 100 pigs out of a total of more than 300 pigs at two pig farms in Pobba Thiri and Zabu Thiri townships in Naypyidaw were infected with the disease. Ten of them died. Four days later, the pigs were diagnosed with PRRS. Authorities say there is no treatment for the disease and no prophylaxis.
Naypyidaw
There are an estimated 100,000 pigs in the district around the country’s newly built capital city Naypyidaw, according to the Health Department. The new capital, is located 320 km north of the previous capital Rangoon.
Similarly, in March, the disease was reported in Aungmyetharsan, Chanayetharsan, Mahaaungmye, Chanmyatharsi, Pyigyitagun, Amarapura and Madaya in the Mandalay region, where more than 1,000 pigs died of the disease.
Dr Tun Myint Soe, the deputy head of the Amarapura Township Animal Husbandry and Veterinary Department, told Mizzima that, currently, there is no PRRS in Amarapura.
Amapura
"There is no spreading of PRRS in Amarapura. The spread of PRRS was stopped by the intense heat," he said. A veterinarian in Pyigyitagun Township told Mizzima that the disease is still spreading in small pig farms in some townships, including Myitnge, Sintkai, Myinchan, and Pyinoolwin in Mandalay region.
"At first, the disease was spread among small farms in urban areas," he said. "Later, the weather was colder. Now the new outbreak has occurred in suburban areas. The death rate is high."
Veterinary department
Earlier this month, the Mandalay Division Animal Husbandry and Veterinary Department distributed insecticide and disinfectant to large pig farms and small scale domestic pig owners free of charge and provided bio-technology control methods during field trips to inspect farms.
The disease was first reported in February in the Mandalay area.
The World Organisation for Animal Health (OIE) earlier issued an emergency warning in Myanmar on the spread of PRRS.

New Zealand pig farmers concerned over PRRS introduction
//15 Apr 2011
Pig farmers in New Zealand are not happy with the government's plans to relax biosecurity around pork imports.
New Zealand Pork is concerned that waste from imported pig meat could end up in the food chain for New Zealand livestock, and potentially spread a disease, porcine reproductive and respiratory syndrome (PRRS).
Ministry of Agriculture and Forestry (MAF) biosecurity officials last year proposed rules that would allow imports of consumer-ready cuts of uncooked pork from Canada, Europe, Mexico and the United States, but were advised by a review panel to look at 29 deficiencies, including their import risk assessment.
But today MAF said it had issued updates to those four import health standards for pig meat, pig meat products and by-products which would effectively manage the risk of introducing PRRS to New Zealand. It said imports of fresh uncooked pork would be restricted to cuts smaller than 3kg that had the lymph nodes removed.
"The risk of PRRS introduction through pork imports will be effectively managed," MAF's deputy director-general for standards Carol Barnao said. "The likelihood of the virus being introduced through the importation of uncooked pork would be equivalent to an average of one outbreak per 1227 years."
But New Zealand Pork said that pigmeat currently imported from countries with PRRS must undergo treatment to deactivate the disease, and eliminating the treatment would open the door for transmission of the disease.
"Pork producers are doing it tough at present," New Zealand Pork chief executive Sam McIvor said. Farmers were "extremely concerned about the risks from the proposed relaxing of biosecurity standards ". Farmers who were already making changes to meet tougher new pig welfare standards did not need to be undermined by the potential for new and exotic diseases "introduced as a result of short-sighted legislation".

PRRS spreads in Burma with over 1,000 pig deaths, OIE issues emergency warning
//14 Mar 2011
Last week it was indicated that Porcine Reproductive and Respiratory Syndrome (PRRS) struck Burma’s second biggest city, Mandalay. The first report of the disease was made on 15 Feb, while currently the disease is rapidly spreading.
Recently it was also said that more than 1,000 pigs have died due to PRRS, also known as blue-ear disease.
Amrapura Township Veterinary and Animal Husbandry Department officer, Dr. Tun Myint Soe, has stated “The disease spreads very fast. Now thousands more pigs have been infected.”
The disease has affected Aungmyetharsan, Chanayetharsan, Mahaaungmye, Chanmyatharsi, Pyigyitagun, Amrapura, and Madaya and Sagaing townships.
No treatment available
Dr. Tun Myint Soe further stated: “We have no treatment for this disease so we’re trying to control it by bio-technology preventive methods and by providing awareness campaigns to the townships. We told people to spray insecticide and disinfectant around a pigsty, to boil their pig feed, to wear footwear before entering pigsties and to use quick lime if they can not afford pesticide and disinfectant’.
Dr. Tun Myint Soe has also stated that the exact number of pig deaths is still currently unknown.
Emergency warning
The World Health Organisation (OIE) for Animal Health has issued an emergency warning in Burma on the spread of the disease.

สถานการณ์โรคระบาด PRRS ในสุกรของไทย
รายงานจำนวนสุกรเสียหายจากโรคระบาด PRRS ของไทย
ที่มา : จากการสอบถามสมาคมฯ หน่วยงานภาครัฐ และผู้เลี้ยงสุกร
หมายเหตุ : ข้อมูลความเสียหายในช่วงตั้งแต่มิถุนายน-ตุลาคม 2553
โรค PRRS (Porcine Reproductive and Respiratory Syndrome) เป็นโรคที่เกิดจากการสืบพันธุ์ และระบบทางเดินหายใจสุกร หรือที่เรียกว่าโรคหูหมูน้ำเงิน (Blue ear) เกิดจากไวรัส PRRS ซึ่งเชื้อดังกล่าวจะผ่านจากท้องแม่สุกรที่ยังไม่คลอดลูก ทำให้สุกรแท้ง หรือแท้งในขณะคลอด โรค PRRS ที่ระบาดในสุกร เป็นโรคที่ระบาดเฉพาะในสัตว์เท่านั้น ไม่ติดต่อสู่คน
เมื่อวันที่ 21 กรกฎาคม 2553 เวียดนามประกาศการระบาดของโรคหูน้ำเงินในเขต 5 เมือง Tan An และได้ทำลายสุกรที่เสียชีวิตและเจ็บป่วยไปแล้ว 200 ตัว ระบาดหนักไปยัง 13 จังหวัดแล้ว พบสุกรติดเชื้อทั้งสิ้น 13,377 ตัว และได้ทำลายสุกรไปแล้ว 5,598 ตัว
โรคหูน้ำเงินสุกร (Blue ear) ที่ระบาดในเวียดนามและลาว ทำให้สุกรในกัมพูชาตายไปแล้วหลายร้อยตัว กัมพูชาจึงได้มีการประกาศห้ามนำเข้าสุกรมีชีวิตตั้งแต่วันที่ 5 สิงหาคม 2553 เป็นต้นไป ทั้งนี้ส่งผลกระทบต่อการส่งออกสุกรมีชีวิตของไทย ไม่มีการส่งออกสุกรมีชีวิตไปยังกัมพูชาตั้งแต่สิงหาคม-กันยายน 2553
นอกจากปัจจัยเรื่องโรคระบาดแล้ว ปัจจัยหนึ่งที่ทำให้ไทยไม่มีการส่งออกสุกรมีชีวิตไปกัมพูชา เกิดจากราคาสุกรของไทยมีราคาสูงกว่าในกัมพูชา โดยสุกรมีชีวิตของไทย (เดือนสิงหาคม-กันยายน 2553 ) อยู่ที่ราคากก.ละ 59-60 บาท ขณะที่ราคาสุกรมีชีวิตในกัมพูชาอยู่ที่ราคากก.ละ 54 บาท ประกอบกับเวียดนามส่งสุกรเข้ากัมพูชาอยู่ที่ราคากก.ละ 54 บาท
ที่มา : มกอช. และสมาคมผู้ผลิตและแปรรูปสุกรเพื่อการส่งออก
