Environmental sampling is an effective means of describing the health and drug residue status of swine populations. Environmental samples can be used to describe anything in the pigs' living area, such as pen floors, feeders and other barn equipment. This video will provide basic instructions of this simple technique for better on-farm health monitoring.

Blood collection, or "bleeding" is one of the most basic and useful skills for the swine practitioner. Serology from blood collection allows veterinarians to run several diagnostic tests, both in the face of disease outbreaks and for routine surveillance.

This video outlines swine lactation, which is one of the most critical factors in the husbandry and health of both sows and piglets. The lactating sow or gilt is the sole source of neonatal piglet nutrition and immunity. Proper lactation is essential for providing baby piglets the ability to grow, thrive, and be successfully weaned. Several management and biological factors play a role in swine lactation. This video will: - describe basic lactational physiology - troubleshoot any issues that may occur during lactation - briefly detail milk collection from the sow

Previously, lactation failure in swine was known as MMA (Mastitis, Metritis, Agalactia) syndrome. Now it belongs to the Postpartum Dysgalactia Syndrome (PDS) and affects the optimum expression of the sows’ productive capacity in a way that is much less clinically visible. It is referred to as a syndrome to indicate that there may be several risk factors and clinical signs that are referred to collectively as lactation failure or, more exactly, an early and temporary dysgalactia (i.e. reduced or insufficient milk production). MMA can be seen as the emerging part of an iceberg represented by PDS, which is the more important and underestimated part and thus most dangerous. It is a major concern to pork producer because of the economic impact although it is difficult to quantify.

A compromised animal, in biological terms, refers to an animal which is unable to function optimally. Observing pigs daily, by walking the pens will contribute to early identification of compromised pigs (1,2). In order to identify sick pigs, it is important to know what a normal, healthy group of pigs should look like. This fact sheet provides illustrations and a system, to be used as a tool, for assessing nursery pigs. This tool systematically assesses the body, eyes/ears/nose, skin/hair, and temperament which can easily be remembered by the acronym B.E.S.T

Tuberculosis or mycobacterial disease (Tb) is reported in about 0.4% of all swine slaughtered under Federal inspection (based on reports from United States Department of Agriculture, Food Safety and Inspection Service [USDA] and probably costs the swine industry an estimated $7.3 million annually. This is not a large amount compared to losses from other swine diseases. Although there are relatively few commercial herds infected with TB, the economic losses can be devastating to those producers that have the disease in their herds. The disease in swine has no apparent effect on the health of the animal. Lack of transmission of the disease from swine to humans cannot be proven. Therefore, USDA meat inspection regulations formulated in 1972 call for special handling of carcasses in which evidence of lesions containing acid fast bacteria are found. Economic losses occur to the swine industry because of these regulations. Tuberculosis has been nearly eliminated in cattle and poultry. Tuberculin testing of cattle with subsequent slaughter of reactors and in some cases depopulation of entire herds, has lowered the prevalence of the disease to about 0.0001% (USDA, 2010 records) in slaughter cattle., The poultry industry has changed to all-pullet flocks and has essentially eliminated Tb. Elimination of older birds over a year of age has been an effective control measure. The rate of condemnation for Tb is 0.0001% in light fowl (USDA, 2011 records). It has been assumed by many that eradication of Tb from cattle and chickens would ultimately lead to its eradication in swine. This has not occurred and mycobacterial infections in swine remain a problem for pork producers.

Porcine pleuropneumonia (PPP) caused by the Gram-negative bacteria Actinobacilluspleuropneumoniae (App) occurs throughout the world. It is rather well controlled in the United States and Canada, however PPP remains a major concern in many Latin-American, Asian and European countries.

Pharmaceutical compounds are increasingly being detected at low levels in ground and surface waters. Although environmental concentrations of pharmaceuticals measured to date are far lower than the intended therapeutic doses, there is concern that the potential exists for these chemicals to have an adverse impact on aquatic life and human health. Disposal of pharmaceutical compounds is becoming a complex environmental issue. According to the United States Geological Survey (USGS), little is known about the potential health effects to humans or aquatic organisms exposed to the low levels of most of the chemicals or mixtures commonly found in their studies. But the safety and health of the environment is directly affected by the disposal method, so it is important that we all be responsible when disposing of these products. Presently, the American Veterinary Medical Association (AVMA) does not offer specific guidelines for disposal of pharmaceutical waste, but they do offer an educational video on the subject, available by visiting www.avma.org and searching “drug disposal”.

In the past few years an expensive swine disease that had largely disappeared has begun to re-emerge in a few Eastern and Midwestern as well as Canadian swine operations. Swine dysentery (SD or bloody scours) is a “gut” disease which is very expensive to treat medically and difficult to effectively remove once pigs and facilities are contaminated. SD is carried by infected swine, other animals in contact with infected swine, as well as small amounts of manure adhered to equipment or clothing. Biosecurity steps that can reduce these exposure risks, and protect your facilities and investments should be immediately implemented to slow the spread of this disease. Your swine veterinarian can assist you in diagnostics and biosecurity plan formulation to protect your herd.

Streptococcus suis infection is a significant disease in intensive, indoor swine operations. Strep suis is now the most common cause of meningitis in pigs submitted to veterinary diagnostic laboratories. Furthermore, there has been a marked increase in Strep suis cases in nursery pigs from herds that have experienced an outbreak of the Porcine Reproductive and Respiratory Syndrome (PRRS). Strep suis is a bacterium living in the tonsils of most pigs and capable of causing disease in the brain (meningitis) and other organs (septicemia). While Strep suis is most often associated with meningitis, other manifestations caused by Strep suis include polyserositis, arthritis, valvular endocarditis, myocarditis, pericarditis and abortion. It is also considered a secondary agent of pneumonia. There are several types of Strep suis. In North America, Types 2 and 3, followed by Types 1/2, 7, and 8 are most prevalent, but types may slightly vary depending on location.
