PIGS diarrhoea Flashcards
what age are piglets weaned
28 days
aim to be >7kg
What are the SIX causes of infectious piglet scour
- Rotavirus
- PED/TGE
- PRRS
- E.coli
- Clostridium perfringes
- Coccidiosis
features of rotavirus and how to limit
very common and prevalent
usually non-fatal.
ensure good hygine with sufficient heat in environment.
what virus is PED/TGE and when are pigs mostly affected
coronaviruses
<4 wks old
usually self limiting
new variant causing bright yellow feaces and is more fatal
how are piglets infected with PRRS and what other clinical other than scour is caused
piglets infected in utero during a disease breakout in the herd.
scour, conjunctivitis, brusing and anemia seen
when do piglets get E.coli and what does the scour look like
occurs during first week of life
watery/CREAMY scour seen
treatment and prevention of e.coli scour
hydration and antibiotics
vaccination of breeding herd
what makes clostridium perfringes scour stand out
death!
type-C causes sudden death in 24hrs due to haemorrhagic enteritis (outdoor systems mostly
type-A low mortality, mild scour
vaccination for long term control
when are piglets usually affected by coccidiosis and what is the type of scour seen
10-21 days old piglets
PASTY YELLOW feaces seen
treatment of coccidiosis
no treatment
control by giving piglets oral toltrazuril at 4 days old
coccidiosis does self resolve at weaning however weaning weight much lower as a result
what are diseases causing diarrhoea in adult pigs
- swine dysentery
- lawsonia intracellularis
- salmonellosis
- Trichius suis
what feature of swine dysentery is almost diagnostic on it own
characteristic smell!
swine dysentery causative agent and clinical signs
brachyspira hyodysenteriae
mucohaemorrhagic scour with characteristic smell.
ulcerative colitis and easily spread
what are the two form of disease cause by lawsonia intracellularis
porcine haemorrhagic enteropathy
porcine intestinal adenopathy
clinical signs of lawsonia diseae
sub clinical form: thickened distal ileum causing malabsorbtion and weight loss
acute form: haemorrhagic diarrhoea with rotten blood smell and blood clots seen in intestinal lumen
what ages do pigs get salmonella
all ages but most common in wenaers and growers
clinical signs of salmonella
pig is fucked
necrotizing enteritis of large and small intstine. congested lungs
if septicaemic purple skin lesions and hepatomegaly
what is seen in pigs with trichius suis and how to treat
mucoid or muchaemorrhagic disease similar to ones seen with swine dysentery.
ivermectin to treat
although not a problem clinically what is a parasite of high significance when it comes to slaughter and why
ascaris suum
milk spot liver!
bz/ivermectins to treat
eggs exceptionally resistant
what are diseases causing diarrhoea in weaner pigs
E.coli
salmonella
characteristic E.coli infection
sudden onset waterzy diarrhoea ONE WEEK post weaning.
apramycing to treat
characteristic salmonella infection in weaners
low grade scour usually
necrotic enteritis causes high grade high mortality diarrhoea
what is the notifiable disease causing diarrhoea
porcine epidemic diarrhoea
coronavirus causing. profuse watery scour and vomiting
PED type 1 in growers
PED type 2 in other pigs
PRRS has many different clinical presentations depending which stage of their lives pigs are affected.
describe PRRS clinical disease in neonate, grower, finisher, sows and boars
neonate=dyspnoea, CNS signs, scour, anemia, high mortality
grower=failiure to thrive
finisher=fever and less food consumption
sow=abortion, stillborn or weak pigs
boar=fever, semen changes
