Internal parasites include various types of internal worms that can naturally infect pigs due to oral ingestion of worm eggs from the pig's environment (pen floors, dirt lots, deep bedding, etc.). Once ingested, internal parasites go through several life-cycle changes as they mature. They compete with the pig for nutrients and may cause tissue damage. Pigs that are heavily infested with internal parasites grow slower and are less resistant to disease and stress. In some cases liver damage due...

At the 2nd Annual London Swine Conference, Dr. Gary Dial spoke eloquently about the costs, consequences and control of endemic diseases in the swine industry. He believes that "we have entered a stage in the competitive evolution of the pork industry when we are being forced to consider any technology promising an advantage either in terms of cost management or revenue enhancement". Thankfully, genetic selection has enabled the industry to take advantage of recent, promising...

Several trials in Kansas have demonstrated that circovirus vaccination improves the performance of growing pigs even on high health farms. On a 300 sow, PRRS negative farm with a history of PCVAD, 235 animals were vaccinated with a porcine circovirus type 2 (PCV2) vaccine at three and six weeks of age. They were housed in the same pens as 250 control (non-vaccinated) animals. Mortality rate and growth rate were significantly better in vaccinated pigs. In the wean to finish stage, the...

A pig virus that exists worldwide has become more dangerous as the virus has mutated and then combined with other pathogens, according to Purdue University researchers. It's not known why a virus that has been known to infect swine for almost 40 years in North America suddenly started causing disease in young pigs in 1991 and then began mutating into more deadly forms. Evidence from research being conducted at the Indiana Animal Disease Diagnostic Laboratory on the Purdue campus has...

Swine internal parasites (worms) are estimated to cost 250 million dollars annually in the United States but they are not considered to be swine killers. Internal parasites devitalize pigs by robbing them of essential nutrients and injuring vital organs. Pigs heavily parasitized are more susceptible to diseases such as scours and pneumonia. The resulting diseases and unthriftiness are a major cause of economic loss. Swine producers should be aware of the common internal parasites of swine and...

Preventing Swine Disease Build-Up Swine disease outbreaks are often related to a high concentration of pigs raised continuously in the same facility or accumulation of disease producing organisms in the environment. These organisms can keep reinfecting the herd. In addition, the movement of hogs from farm to farm can introduce new infectious disease-producing agents into the herd. The possibility of an outbreak can be greatly...

Researchers have identified a new strain of swine influenza—H2N3—which belongs to the group of H2 influenza viruses that last infected humans during the 1957 pandemic. This new strain has a molecular twist: It is composed of avian and swine influenza genes. Agricultural Research Service (ARS) veterinarians Juergen Richt, Amy Vincent, Kelly Lager and Phillip Gauger conducted this research with Iowa State University (ISU) visiting scientist Wenjun Ma, ISU veterinarian Bruce Janke and...

New studies led by the Animal Sciences Group at the Wageningen University in the Netherlands have confirmed that using specific plant extracts proved to be effective for organic deworming in pigs. Researchers stated that the combination of conventional synthetic drugs and a diet with herb mixture containing Thymus vulgaris , Melissa officinalis and Echinacea purpurea is a good option for organic farmers with mild infection levels of Ascaris suum in...

On Friday, November 23, Lallemand Animal Nutrition and ISPAIA, the French Institute for Animal Production and Agro Industry, hold a technical meeting dealing with the nutrition and health issues around sow’s farrowing, the cornerstone of pig production cycles. The event focused on the importance of a balanced digestive microflora and the unique potentials of probiotic yeast Saccharomyces boulardii, for which research and development have been driven by human applications for over 50...

Pigs can now be added to the list of potential carriers of the drug-resistant "superbug" methicillin-resistant Staphylococcus aureus (MRSA). Researchers at the University of Guelph have discovered the bacterium in 25 per cent of pigs and 20 per cent of hog farmers in Ontario. Their study — the first in North America — was published this week in the journal Veterinary Microbiology. It's an important finding because it shows the bacterium can be readily passed from...

A zoonosis is an infectious disease naturally transmissible between vertebrates and man. At first sight the list of potential zoonoses is quite imposing; however when the exotic and rare zoonoses are removed from the list it is easier to focus on a relatively short list of important pathogens. Whilst the threat of zoonoses from pig meat is significantly lower than that from other species, it is vitally important that all parties involved in the pig industry focus on reducing the risk of...

It is estimated that in 2030 the world population will be close to eight billion people, which corresponds to an annual increase of 4%. In the same period, global food production is projected to increase by only 2% per year. Therefore, given that an increasing amount of grain and oilseed crops will be used for human food, a growing concern exists in terms of a shortage of conventional feedstuffs to be used in animal production. Additionally, legislation in some countries has banned the use...

Agricultural Research Service (ARS) scientists are part of a team that has found a vital clue for battling a disease called porcine reproductive and respiratory syndrome virus (PRRSV), which costs U.S. swine producers about $560 million annually. PRRSV-infected pigs are susceptible to pneumonia and reproductive losses, and infected sows give birth to weak piglets. It can take weeks or even months for them to recover from the virus, which evolves and adapts quickly to environmental...

It is now clear that Bio-Mos® improves the growth performance of young pigs (Miguel et al., 2004). The response occurs over a wide range of weaning ages, types of diets, and dietary Bio-Mos® concentrations, and with or without antibiotics in the diet. The performance improvement is greatest during the early days after weaning, and is greater in situations where pigs grow more slowly, but we did not identify other factors consistently related to the Bio-Mos® response. The greater...

China is stepping up efforts against an outbreak of deadly pig disease that has spread through much of the vast nation and sent pork prices skyrocketing, the Agriculture Ministry said Thursday. Blue ear, also known as porcine reproductive and respiratory syndrome, has infected 280,000 pigs since the start of the year, killing more than 70,000, chief veterinary officer Jia Youling was quoted as saying at a news conference by the official Xinhua News Agency. China has already...
