Swine Diseases

COMMON SWINE DISEASES

Enteric Diseases

1 . Colibacillosis- is the leading killer of piglets , accounting for 42 percent of all death losses nationwide . It attacks piglets as young as 2 to 3 hours . It is caused by an E . coli bacterium which attacks the lining of the intestine which then produces toxins . Such toxins make fluid and food absorption impossible resulting to fluid loss and dehydration

2 . Ileitis (proliferative enteropathy )- causes inflammation of the ileum and a sudden onset of diarrhea . There are cases when Ileitis causes persistent diarrhea leading

to death of grow-finish pigs

3 . Swine dysentery (bloody scours ) - a common diarrheal diseases that affects the large intestine which is caused by Brachyspira (Serpulina hyodysenteriae . The bacterium causes an inflammation of the beneficial mucosa which leads to a bloody diarrhea

4 . Enterotoxemia - is caused by the rapid multiplication of the bacterium known as Clostridium perfringens Type C in the intestine . The release of toxins by these types of bacteria causes death to its victim The Type A of this bacterium produces exotoxins which causes yellow-to-white pasty diarrhea that usually attacks during the first weeks of the pig 's life . It naturally resides in the swine 's intestine and said to be the leading cause of diarrhea in neonatal pigs

REPRODUCTIVE DISEASES

Erysipelas - a bacterial infectious disease classified as acute sub-acute and chronic erysipelas . The most susceptible to this disease are the newborn piglets especially those that are recently weaned . Acute Erysipelas causes red skin lesions that appear within 2 to 3 days of high fever . The skin lesions usually appear to be diamond-shaped from which its common name diamond skin disease ' came from . The said disease also causes depression and lameness of the victim . The sub-acute erysipelas form has the same symptoms but is less severe . Arthritis lameness and other sub-clinical infections are the symptoms that are exhibited by the chronic form of this disease . If breeding herd is affected , the disease will cause abortion and stillbirth . Affected will then have a poor reproductive performance , producing weak piglets

Leptospirosis - causes abortion and stillbirths , including the birth of weak piglets . AS with mice and dogs , this contagious disease contaminates the feeds and water through the urine which spreads the disease . It will then be transmitted thru the milk by nursing piglets

PRRS (Porcine Reproductive and Respiratory Syndrome ) - a viral causing abortion , stillbirths and mummified fetuses . Sows and grower /finisher pigs affected have breathing difficulty . It causes death in pre-weaned and nursery pigs and poor performance in those that were able to survive . PRRS is a recently recognized disease of pigs , the agent of which is the virus identified to be one classified in the of Nidovirales family of the Arteriviridae . There were already reported cases this disease in the USA , Japan , Vietnam , Korea and the Philippines

The disease occurs in two phases : first , the reproductive failure and second , the respiratory failure . Reproductive failure affects sows the respiratory disease attacks on herd lasting for about 6 to 12...
