Diet-induced diarrheal disease can be prevented by not overfeeding protein and other ingredients such as fat. Gradually switch the pig from one type ration to another. Make sure the pig finds the water source because water intake is important for adequate feed consumption. A lack of water for a couple of days followed by overconsumption of water can be fatal; this condition is called salt toxicity or water deprivation.
Routine deworming in show pigs is commonly performed during the first week after purchase at about 8 to 10 weeks of age or 50 pounds, and then about a month later.
Another option is to take a fresh stool sample to a veterinarian for fecal flotation and microscopic examination for whipworm eggs. It takes a minimum of 42 days from the time a pig is infected until adults are present and eggs are passed in feces. This means fecal examination for whipworm eggs before 6 weeks of age is not necessary. Also, whipworm adults are intermittent egg layers so one negative fecal flotation does not completely rule out whipworm infection.
Swine dysentery is preventable by obtaining pigs directly from a farm that is free of swine dysentery and minimizing exposure to other swine or feces-contaminated premises, trailers and equipment such as scales.
Absence of diarrhea containing blood and mucus, excellent growth performance and no significant death loss in pigs from weaning through market weight are evidence of freedom from swine dysentery in a herd. The following medications are included in show swine rations by feed manufacturers to prevent swine dysentery:.
Mecadox is another alternative feed medication to prevent swine dysentery, but it has an extremely long withdrawal time. It is best to take show pigs off of all medication even 0-withdrawal medication at least 24 hours before exhibition. The best prevention for salmonellosis is to obtain the healthiest pigs possible and to manage pigs to reduce stress and maintain good sanitation practices.
It is generally not a good practice to put antibiotics in the feed to prevent salmonellosis because antibiotic resistance is very common with salmonella species. Vaccines are available for S. There are numerous sources of salmonella, and any of these can cause human disease if the organisms are ingested. Animal and human exposure to salmonella can be minimized by proper sanitary measures, such as handwashing with antiseptic soap, proper livestock and pen management, bedding changes, premise cleaning and disinfection, pasture rotation, rodent control, and proper food preparation and cooking.
TGE can be prevented by not exposing swine to sources of the virus. Vaccines are available that control the effects of disease; they do not prevent infection with TGE. Diarrheal disease is one of the most important disease problems in show swine from 5 weeks of age about 25 pounds through the last day of exhibition.
Prompt diagnosis and treatment are important because chronic, undiagnosed diarrhea frequently results in death. A veterinarian should be consulted to assist in the prompt diagnosis, treatment and prevention of this and other conditions.

Dietary Causes Nutritional causes are relatively easy to detect and correct. Parasitic Causes Whipworms are a major cause of diarrheal disease in show pigs. CNN A year-old Maryland man is doing well three days after receiving a genetically modified pig heart in a first-of-its-kind transplant surgery, University of Maryland Medicine said in a news release Monday. More Videos Hear from doctors who transplanted a genetically modified pig heart to a man David Bennett had terminal heart disease, and the pig heart was "the only currently available option," according to the release.
Bennett was deemed ineligible for a conventional heart transplant or an artificial heart pump after reviews of his medical records. I want to live. I know it's a shot in the dark, but it's my last choice," Bennett said before the surgery, according to the release.
Virus can be demonstrated in frozen sections of small intestine using a specific fluorescent antiserum or monoclonal antibody using immunoperoxidase, or by detection of viral nucleic acid in fixed tissue. Virus can be isolated from mesenteric lymph node, tonsil and small intestine which may be frozen. There is no treatment. Affected piglets can be supported using electrolyte replacer solutions. Early weaning, high environmental temperatures and hygiene may all help reduce mortality. Cross sucking of litters onto immune sows may also help.
Water should be freely available to weaned pigs. Antimicrobials may control infections by other enteric pathogens. Prevention of entry to farms relies on isolation, exclusion of unnecessary visitors or contaminated lorries and use of showers or disinfectant dips for visitors. Pigs remain carriers for days and should not be purchased during epizootics of TGE, but may be safe after 40 days.
Entry may still occur by bird or wind transmission up to 1. When an outbreak occurs, sows due to farrow within 14 days should be maintained in isolation. Sows which are more than 14 days from farrowing can be infected with intestinal contents from dead pigs where legal and may develop immunity in time to protect their litters. It was concluded that TGE virus probably replicated in all feeder swine exposed, and that the presence or absence of clinical signs of TGE in these pigs was related to the severity and extent of the villous atrophy and columnar cell replacement induced in their small intestines.
