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.

1 Introduction Among all infectious agents affecting swine, airborne pathogens are the most costly and difficult to control (Hyslop 1971). Porcine reproductive respiratory syndrome (PRRS), influenza A (IA), foot and mouth disease (FMD), classical swine fever (CSF) and porcine epidemic diarrhea (PED) viruses are important swine pathogens that spread via aerosols (Sta¨rk 1999)....

INTRODUCTION Pig production around the globe has become very sophisticated with well-controlled environments that, if controlled properly, maximize animal well-being and production efficiency. The major thermal challenge in pig housing is economical mitigation of heat stress. Unlike cold weather periods where relatively inexpensive heating devices can be used to optimize thermal conditions, mechanical...

The period following weaning is characterized by a high incidence of intestinal disturbances with diarrhoea and depression of growth performance in piglets. At weaning, pigs have to deal with the abrupt interruption in the established social interaction with sow and littermates and the stress of adapting to a new environment. In addition, the piglet has to cope with the sudden withdrawal of sow milk and adapt to less digestible, plant-based dry diets containing complex protein and...

INTRODUCTION Streptococcal infections are one of the leading causes of economic and production losses in pig farming (1, 4). These infections are caused by the Streptococcus suis bacterium, whose natural habitat is swine (mainly in the upper respiratory, digestive and genital tracts), where it represents the most important primary pathogen (1, 2). Exist 35...

The presence of zearalenone in feed is unavoidable and zearalenone toxicosis is hard to treat. The most practical way to treat zearalenone toxicosis is to use an enterosorbent to prevent the initial dietary absorption by the gut and subsequent conjugated zearalenone compounds from being reabsorbed via enterohepatic circulation. Due to its rapid absorption in the small intestine, the inactivation of zearalenone after ingestion becomes extremely critical in...

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...
