Grower/Finisher Pig Diseases Flashcards
what is the weight of grower/finisher pigs (16-17 weeks old)?
60-280 lbs
What are 7 respiratory diseases that can occur in grower/finisher pigs?
- mycoplasma hyopneumoniae
- pasteurella multocida
- actinobacillus pleuropnuemoniae
- SIV
- PRRSv
- CV2
- Ascaris suum
A group of grower/finisher pigs have dry, hacking coughs and have seemingly stopped growing. You diagnose them with mycoplasma hyopneumoniae. How do you treat these pigs?
lincomycin
what is the best way to prevent mycoplasma hyopneumoniae?
vaccinate them!
What is a unique feature of actinobacillus pleuroneiumoniae in grower/finisher pigs?
it creates caudodorsal fibronecrotic lung consolidation as opposed to cranioventral.
how do you treat actinobacillus pleuropneumoniae in grower/finisher pigs?
penicillin or ampicillin but mostly not successful. This disease is notorious for causing sudden death.
A group of grower/finisher pigs have moist coughs and are thumping (rapid, shallow breathing). One pig was found dead, so you perform necropsy and find milk spots on the liver. What is the most likely diagnosis?
Ascaris suum –> verminous pneumonia
The reason for the moist cough and thumping is transtracheal roundworm larval migration
how do you treat ascaris suum in grower/finisher pigs?
injectable ivermectin
What are the 4-5 MAJOR causes of diarrheal disease in grower/finisher pigs?
- Salmonellosis
- Swine Sysentery (brachyspira hyodysenteriae)
- Proliferative Enteropathies (lawsonia intracellularis)
- Trichruris suis (whipworm)
- Transmissable Gastroenteritis Virus (TGE)
E. coli, rotavirus, coccidiosis are MUCH less likely to occur in this age group of pigs.
Which of the following is/are NOT a feature of salmonellosis in grower/finisher pigs?
A. diarrhea
B. septicemia
C. purple skin discoloration
D. abscesses
E. enlarged mediastinal lymph nodes
F. swollen joints
G. button ulcers
D. abscesses
F. swollen joints
how do you treat proliferative enteritis in pigs?
tylan (tylosin)
what organism causes proliferative enteritis in pigs?
lawsonia intracellularis
(a gram neg, NSF, anaerobic obligate intracellular bacteria)
What is the prognosis for hemorrhagic bowel syndrome in pigs?
poor
causes sudden death
Gastric ulcers in pigs relatively common. What are some causative factors?
- finely ground feed
- stress
- anorexia
how can we treat/prevent gastric ulcers in pigs?
- increase courseness of food
- decrease stress
- change feed
- give gastroprotectants
what are 6 GI conditions that affect grower/finisher pigs?
- hemorrhagic bowel syndrome
- gastric ulcers
- mesenteric torsions
- ascaris suum
- hemorrhagic ileitis (lawsonia)
- rectal prolapse
how do we treat rectal prolapses in grower/finisher pigs?
place pig whistle to cause ischemia and necrosis, give something for pain relief and antibiotics.
Separate the pigs because the other pigs will chew off the prolapsed tissue :/
what are 9 skin lesions that occur in grower/finisher pigs?
- external parasites (mites, lice)
- insect bites (flies)
- sunburn
- PCV2 lesions
- pityriasis rosea
- erysipelas
- calluses of knee/hock/etc
- abscesses
- ringworm (not common)
how would you treat pityriasis rosea in pigs?
no treatment, they will grow out of it in 3 weeks.
how would you treat ringworm in pigs?
dilute bleach
what are the 8 causes of lameness and locomotor lesions in grower/finisher pigs?
- erysipelas + mycoplasma infection (swollen joints + stiffness)
- osteochondrosis dessicans (bc fast growing)
- osteoarthritis, DJD
- laminitis
- overgrown and torn hooves + dewclaews
- bruises + cracks in feet, etc
- rickets (uncommon)
- porcine stress syndrome
what is the cause of most lameness in grower/finisher pigs?
standing on concrete for long periods of time.
The plastic coated wire flooring is easier on them.
T/F: we do not treat OCD in grower/finisher pigs
true
