Swine health
Pig diseases can be caused by bacteria, viruses, protozoa, nutritional deficiencies, poisonous substances, internal and external parasites.
Bacterial diseases include swine erysipelas, swine dysentery, infectious poly-arthritis etc. Viral and mycoplasma diseases include African swine fever, swine influenza, enzootic pneumonia of pigs, vesicular exanthema of swine, transmissible gastroenteritis etc. Helminthiasis as a health problem in pigs is mainly caused by worms like the lungworm, ascaris worm etc. Nutritional diseases include piglet anemia, parakeratosis etc. External parasitic infections include mange, lice, jiggers etc.
How to tell that a pig is in bad health:
General signs: dullness, loss of appetite, labored or rapid breathing, sudden deaths, loss of weight, low weight gain and fever usually manifested by shivering of the pig.
Signs expressed on the skin: reddening of the skin or skin discoloration, loss of hair and hardening of some parts of the skin, itching and cracking of the skin.
Other signs: lameness, cough, abnormal nasal discharges, diarrhea with a putrid smell, abnormal content and color of feces and abortions.
Lameness among sows may be and must be regarded as a loss-making disease. Lameness is not a common state for sows, and several international studies indicate losses due to lameness amounting to 50 - 100 Euros per sow. According to professor John Deen, University of Minnesota, loose sows increase the risk of lameness by a factor 25; this will consequently increase the lameness problematic in European pig production due to the fact that all sows as...

Antibiotic Associated Diarrhoea (AAD) is diarrhoea caused by antibiotic (ATB) supplementation and usually occurring during or following ATB treatment. This phenomenon is highly spread in hospitals or health care houses where patients usually contract diarrhoea when receiving ATB treatment. The major identified bacteria causing AAD is Clostridium difficile . Many C.diff infections can be observed in UK hospitals causing up to death of some patients, mainly...

Feedback from the usage of Levucell SB (LSB) in sow diets is rich of visible signs of success during the lactation period and around farrowing. However, these results are usually obtained after feeding LSB throughout the gestation phase whith no visible signs. Consequently, LSB is often perceived as a cost-increasing factor by nutritionist. Production trials allowing a chance to measure any improvement are very unlikely to be performed. Due to 'natural'...

It is widely recognized that a large variation in productivity and profitability exists between farms in a country, and similarly, between countries in a global economy. Some profitability variables are due to cost of inputs and management and these are controllable by producers; other factors are not so easily predicted or controlled, for example: 65% of income variation is estimated to be due to: Feed conversion, ...

Introduction Through the late 1990's and on into the present century the global swine industry experienced very profound changes. The price crash in 1997/98 was especially traumatic and the outbreaks of CSF and FMD were also particularly damaging. A new emerging disease that became known as Post-weaning Multi-systemic Wasting Syndrome (PMWS) and its related Post-weaning Dermatitis Nephropathy Syndrome (PDNS) then appeared all over...

Salmonella control has a high priority in European pork production. It is a significant cause of human Salmonellosis and causes major economic losses in the pork production chain, through reduced productivity, increased veterinary and hygiene control costs. Preventing the spread of salmonella to the consumer requires special control measures during slaughter and processing. The extra cost of these controls is increasingly being...

Dear Users,
This is an interesting forum from our Spanish community, generated by Fabián Ruiz Herrera from Perú:
Is it proper the use of iron dextran at doses of 1 mL at 3 days old and then a second dose at 10 days with equal doses for the prevention of iron deficiency anemia (both associated with vitamin B12)? Or are there other additional doses? Or another schedule?
Best Regards.
Fabián Ruiz Herrera

The porcine Circovirus type 2 (PCV2) is considered an important emerging pathogen in swine production. It has been associated to different syndromes and porcine diseases like the Porcine Dermatitis and Nephropathy Syndrome (PDNS) and the Post weaning Multisystemic Wasting Syndrome (PMWS). There have been found other infectious agents associated to PCV2, like the Aujeszky's disease Virus (ADV), Porcine Parvovirus (PPV), Porcine Reproductive Respiratory Syndrome Virus...

Preliminary results from three researches indicate that the novel influenza A virus (H1N1) is transmittable in swine populations, earlier Swine Influenza Virus immunity does not seem to protect against the virus, but the novel virus does not seem to affect any other tissue than the respiratory tract.
A British study, released in the end of May and, coordinated by the Veterinary Laboratories Agency in Weybridge, UK, found that the virus can be transmitted among pigs,...
