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.

Introduction Coccidiosis is an infectious disease of the intestinal tract of wild and domestic animals caused by different protozoa. These include but are not limited to Isospora, Neospora, Cryptosporidium, and Eimeria of the phylum Apicomplexa. Those parasites are widespread, especially where intensive production systems are used to raise livestock. They cause mortality, poor growth, and impaired performance. In addition to mortality and reduced growth, coccidiosis also affects...

In the last 10 years, Clostridium difficile has been implicated as a major cause of neonatal diarrhea in pigs.1 Clostridium difficile infection (CDI) typically affects piglets ranging in age from 1 to 7 days. Clinical signs of CDI include diarrhea, abdominal distention, and scrotal edema, with most of the pathology being attributed to toxins A and B. 2 The prevalence of C difficile is widespread in the United States and has been referred to as the most important uncontrolled cause...

1. Introduction Porcine reproductive and respiratory syndrome is an important disease in swine industry. The disease has become endemic in many countries throughout the world following an epidemic phase. It is caused by infection with the Porcine Reproductive and Respiratory Syndrome Virus (PRRSV), a small single-stranded, non-segmented RNA virus [1]. The virus is enveloped, spherical and ranges in size from 45 to 80 nm in diameter. PRRSV is differentiated into two genetically...

1. Introduction Classical swine fever (CSF) remains a highly relevant disease in swine, causing major losses to the industry which are related to various forms of disease [1]. CSF has been eradicated in the US and Western Europe and remains endemic in several countries, including Asia, Central and South America, and Eastern Europe, with a recent outbreak being reported in Japan [2]. The disease is caused by the CSF virus (CSFV), a positive stranded RNA virus that belongs to the...

Introduction Calcium (Ca) and phosphorus (P) are the two most abundant minerals in the body of the pig and are required for many important physiological functions (Oster et al., 2016). The vast majority of Ca—about 99%—is not only present in skeletal tissues (Nielson, 1972), but it also fulfills other very important roles involving blood clotting, nerve impulse transmission, muscle contractility, and fluid balance, to name a few (Pravina et al., 2013). In contrast,...

1. Introduction Creatinine (2-amino-1-methyl-2-imidazoline-4-one) is the final metabolism product of creatine in mammals [1], which is excreted exclusively by the kidneys via glomerular filtration and, to a lesser extent, by tubular secretion [2]. Under physiological conditions, its excretion throughout the day is relatively constant, the amount of creatinine produced is proportional to the muscle mass of the individuals [3]. In contrast, urine production depends on the...

Erysipelas is a contagious infectious disease of pigs caused by the bacterium Erisipelothrix rhusiopathiae. The Swine Erysipelas is an actual disease, as reported Schwarts (AASV 2002) with the increase of cases at the University of Iowa, with economic impact in the herd losses may include loss of death (1%) - $ 2.50dls/hembra; treatment cost $ 1/hembra; abortion (4%) - $ 5dls/hembra for a total of $ 10dls/hembra. Also in the growth stage - complete the death loss (3%) - $ 2.50dls; treatment...

1.1 | Introduction
Effective biosecurity protocols are essential towards protecting the health status of swine farms. In the United States, tremendous resources have been invested to reduce the risk of viral pathogens, such as the entry of porcine reproductive and respiratory syndrome virus into susceptible populations. Protocols including shower in-shower out, transport...

Salmonella 1,4,[5],12:i:-, an emerging serotype in swine, has become one of the most identified serotypes in pigs, pork, and humans worldwide. It captured the attention of an American Association of Swine Veterinarians member who recommended the Swine Health Information Center (SHIC) develop a fact sheet on this bacteria for the benefit of the US pork industry. As a result, the new S....
