Swine Diseases (PPT ni doc) Flashcards
Is a condition that can occur in sows and gilts within 72 hours after farrowing
Mastitis-Metritis-Agalactia Syndrome
Apparent when piglets go from teat to teat when the sow
finally permits them to nurse.
Agatactia
Lack of good nutrition
Mycotoxin
Loss of apetite and general lethargy
Pyrexia
First indication of MMA
weak appearance of the pigs
A common cause of death in neonatal piglets. Glycogen reserves are soon depleted if pigletsbecome chilled or fail to ingest an adequate amount of milk.
hypoglycemia
Is caused by breaks in bones (especially in the pelvic area) weakened by poor mineral or vitamin nutrition. These breaks and lamenesses often occur after weaning but may happen in the farrowing house
Downer sow
Infectious diarrhea in piglet is/are attributed to what bacterial organism?
Escherichia coli
The type of diarrhea is
characterized by yellowish, very
fluid, foul smelling smelling stool. It
affects animals from 1 day old up to one week after weaning.
Infectious diarrhea
Streptococcal arthritis causative agent
Stretococcus suis
can cause acute and chronic arthritis in one to three
week old piglets.
Streptococcal arthritis
found commonly in the nasal cavity of swine and is frequently a secondary invader following pneumonia.
Mycoplasma hyorhinis
Is found commonly in the nasal cavity of swine and is frequently a secondary invader following pneumonia.
Mycoplasma hyorhinis
Causative agent of tetanus
Clostridium tetani
The bacteria are found in soil and can survive there for many years. Swine of all ages maybe affected by tetanus . The majority of all cases however, involve young pigs which may have contracted the disease through castration wound or umbilical infection.
Tetanus
The disease starts with the reddening of the skin
then become wet and covered with crusts.
Greasy Pig Disease also known as
Exudative epidermitis/Marmite disease
Causative agent of Greasy Pig Disease also known as
Exudative epidermitis/ Marmite disease
Staphylococcus hyicus
It may sometimes
resemble mange but the crusts
are easy to remove and the skin
below is wet, rough and
reddish.
Greasy Pig Disease also known as
Exudative epidermitis/ Marmite disease
A disease characterized by 1- to 20-cm raised, reddened, ring-shaped lesions on the skin. Lesions first
develop on the skin of the ventral abdomen but occasionally start in other areas.
Pityriasis rosea or pustular psoriaform dermatitis
is a sporadic disease of unknown
etiology of pigs, usually 6–14 weeks
of age, but occasionally as young as
2 weeks. One or more pigs in a litter
may be affected.
Pityriasis rosea
(pustular psoriaform dermatitis)
A skin disease caused by a fungus Microsporum nanum or Trichophyton verrucosum
Ring worm (dermatomycosis)
Causative agent for ring worm
Microsporum nanum
or Trichophyton verrucosum
Mange in pigs is principally
due to infestation
with?
Sarcoptes
scabiei var suis
The common signs are ear shaking and severe rubbing
of the skin against the sides of the pen. Approximately
3-8 weeks after initial infection, the skin becomes
sensitized to the mite protein and severe allergy may
develop.
Acute mange
Thick asbestos –like lesions develop in the
ear, alongthe sides of the neck and elbows
and front parts of the hocks and along the
top of the neck.
Chronic mange
Characterized by high fever, loss of appetite,
reddening of the skin and hemorrhages hemorrhages of the internal organs, and death which follows
between 2-10 days on the average.
African Swine Fever
ASF causative agent
Asfarviridae family
T or F: ASF is not a human health threat.
True
ASF can spread through
- Biological vector (ticks)
- Direct contact
- Indirect Transmission
A case characterized by combinations of the mentioned signs.
Suspect case
Elements in the suspect case plus history of pig introduction, practice of swill feeding, or pig access to garbage or rubbish dumps
Probable Case
Laboratoy confirmed case; detection of virus
Confirmed Case
Strict Biosecurity Measures
- Biosecurity Level 1
- Health care program
- Awareness of raisers/community
Control
- Culling
- Border Control
- Early reporting and surveillance
- Legislation
