Piglet diarrhea (Bromfield) Flashcards
1
Q
Colibacillosis
A
- E. Coli
- white scours/wet tail scours
- up to 100% morbility
- 60-75% mortality
- around 2-3 days of age
- TX
- fluid/electrolytes
- DX
- history, CS
- response to Gentamycin
- Control
- vaccination for sows
- All in all out
2
Q
TGE
A
- Transmissible Gastroenteritis
- highly infectious viral disease (coronavirus)
- all ages
- Eipzootic morbidity: 100%
- vx and dx: attacks villus
- Enzootic: usually outbreaks in weaned kids
- Necropsy: thin walled SI
- No tx
- vaccines not great
- birds can be carriers
3
Q
PEDv
A
- Porcine Epidemic Diarrhea Virus
- coronavirus
- morbidity up to 100%
- villus blunting
- same as TGE
- 3 wk old pigs will not survive
- profuse water diarrhea and vx
- biosecurity, vaccination, bird/animal control
4
Q
Coccidiosis
A
- Sow not source
- oocysts in piglet environment
- must be at least 4.5-5 days old (piglets)
- merozoites, micro and macro gametes in SI
- hygiene and heat treatment
- coccidiostats only
5
Q
Clostridial Enteritis
A
- < 7 days old
- necrotic, hemorrhagic enteritis
- perfringens type C
- in soil
- CS: death, or bloody diarrhea, or death
- post mortem, impression smear, culture
- TX: penicillin (PPG)
- vaccination
- antitoxin, abx to sows, hygeine
6
Q
Rotavirus
A
- takes off tip of villus
- killed by ethanol and everything
- very common
- 7-14 days old piglets
- some vomiting
- TX: fluids, Abx, TLC
- vaccination not great, sow management
7
Q
breakdown preweaned pigs
day 3-4 or younger
day 6-7
day 7+
A
- day 3-4 or younger: likely E. Coli
- day 6-7: coccidia
- day 7+: Chlostridia, possibly rotavirus
8
Q
Colibacillosis
post weaning
A
- E. Coli (different from other E. Coli)
- postweaning diarrhea
- loss of lactogenic immunity
- edema
- 20-50% morbidity, up to 10 % mortality
- fever, maybe
- no villous damage
- dx: clinical signs, culture (look for specific E. Coli)
- TX: anything that treats G-s (feed medication)
- control: creep feeding
- vaccination for little guys not great
9
Q
Edema Disease
A
- related to E. Coli
- edema
- gut, eyelids, face, nervous signs
- death of good doers
- oral exposure
- DX: CS, culture spec E. Coli and edema inducing toxin
- DDX:
- PRV (pseudorabies)
- Mulberry heart
- arsenic
- ABX, acidifying feed
- vacc not great, get rid of genetic carriers
10
Q
Salmonellosis
A
- not typcally same salmonella that people get
- primary dz of grow/finish pigs
- septicemic form
- fever, restless, anorexia, cynosis
- enteric form
- fever, dehydration, dec body cond, fast spreading diarrhea
- necropsy: skin discoloration, larger LN, focal nec, inc L.N. size
- isolate, dec stress, inc hygeine
- pulse feed antibiotics, or vaccines
11
Q
Serpulina (brachyspira) hyodysenteriae
A
- bloody, mucoid diarrhea
- up to 40% of farms
- anaerobic spirochete
- morbidity: 100%, mortality 30%
- can shed for up to 70 days
- organism can survive in lagoon, H2O, dogs, mice, starling, flies
- not a ton of chronic dz
- lesions limited to mucosa
- DX: CS, postmortem, culture
- DDX: salmonellosis, NPE (ileitus), TGE
- TX: anything
- De pop/ re pop
12
Q
Serpulina (brachyspira) pilosicoli
A
2nd verse same as the first
13
Q
PIA
Procine Intestinal Adenomatosis Complex
A
- ileitis
- inc prev in hi health herds
- easy to treat
- lawsonia intracellularis
- fecal oral transmission
- mid-grower, early finisher
- PIA: mild signs => wt. loss, dec appetite, diarrhea
- NE/RI: more severe diarrhea and wt. loss
- PHE: acute hemorrhagic anemia, melena, death
- spontaneous recovery in 4-6 weeks
- Necropsy: icky ileum (thickened)
- DX: HX and clinical signs, clean herd
- DDX: salmonella, swind dysentery (SD)
- Oral vaccine when off antibiotics
14
Q
Gastric Ulcers
A
- ulceratio of pars esophagae
- 2-100% animals at slaughter
- 24 hours off feed (chicken or egg?)
- Etiology: stress, finely ground feed, gastric acidity
- Clinical signs: Peracute-dead; chronic-melena, weight loss, anemia, abdominal pain
- bleached out pigs…
- DX: HX and CS, melena, anemia
- DDX: PHE
15
Q
Grower sized pigs with bloody diarrhea could be
NAVLE
A
- Salmonella
- PHE (Ileitis)
- SD
