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.

The total number of born piglets increases with parities, but the higher prolificacy results in lower individual average birth weights and more heterogeneous litters. Variations in piglets’ birthweights are related to their number of muscular fibers resulting in variable performances after birth (Rehfeldt and Kuhn 2006). The skeletal muscle...

1. Introduction. There are limited data on the effectiveness of disinfectants against Lawsonia intracellularis, a Gram-negative obligately intracellular bacterium that causes proliferative enteropathy (PE) (Lawson and Gebhart, 2000). This is mainly due to the difficulty of finding good methods to measure the efficacy of disinfectants against an obligately intracellular bacterium. One study used a conventional tissue...

I am having a problem with the viability of boar sperm. Human, horse and other animal sperm are viable in a glass chamber used for counting sperm but boar sperm die. I think it might be the UV curing adhesive. to hold the glass together. Also I have been coating the glass with PVA. Any recommendations for a UV adhesive that is not toxic to boar sperm. Any recommendations for coating glass so boar sperm do not stick?...

Swine Dysentery (SD), commonly known as bloody scours, is a troublesome disease which had been virtually eliminated through scientific breakthroughs in the 1970s and 1980s. But today, likely due to changes in production practices, it has begun to re-emerge and again cause disease and death in hogs. SD is too costly a disease to live with. When an infection is suspected, it is important to get as early and accurate a diagnosis as...

In the early 1940´s the first antibiotic— penicillin—was used successfully to treat bacterial infections and to save thousands of lives, including those of wounded World War II soldiers. Today, antibiotics, which target microorganisms like bacteria, fungi, and parasites, are essential for human and animal health. They continue to save lives as well as increase animal production and efficiency. However, exploration of alternative...

The name “Brachyspiral colitis” recently was introduced into the literature on swine diseases to describe the situation where colitis, diarrhea and/or dysentery occur in pigs infected with one or more pathogenic Brachyspira species (Hampson, 2012). The term was created to emphasise an increasing understanding of the diversity of anaerobic intestinal spirochetes in the genus Brachyspira and the fact that a number of different species...

(1) Coliform Mastitis (CM) in sows is the term used for a variety of different Mastitis Problems in sows. Some names are MMA, PPDS, and PDS. It can cause high mortality rates in nursing piglets. (2) Since Coliform Mastitis usually occurs at 12 to 48 hours after parturition, it occurs when the piglet is most vulnerable. Piglets are still absorbing some “Colostral Effect” up to 24 hours of age, and even at 48 hours of age they do not have an...

Introduction Necrotic ear syndrome or ear necrosis in pigs has been reported as an increasing health problem in many countries with intensive pig farming. 1 It is characterized by large erosive lesions at the margin of the pinna(e) in both sexes. It occurs mainly in weaning pigs and growers/ fatteners with bodyweight ranging approximately from 10 to 40 kg. 2 The earliest lesions are normally visible on the ear' tips at 6-7...

Meningitis is a serious complication of Streptococcus suis bacteremia in young piglets. This microorganism is also an emerging human pathogen that has been recently implicated in a case of meningitis in a swine handler (Wertheim et al., 2009; Fowler et al., 2013). In order to access and infect the brain meninges, blood-borne S. suis must penetrate the blood-brain barrier of affected animals or humans. The purpose of this article is to briefly...

H. parasuis is considered one of the most important bacterial pathogens affecting pigs. Vaccines and other management strategies have not always been successful in controlling the losses associated to H. parasuis . This bacterium frequently colonizes the mucosal of the swine upper respiratory tract. Oliveira et al., (2004) showed that exposure of young pigs to a low dose of...
