zoonotic

22
Q

what does SMEDI do?

A

full term litter with small mummies, full grown stillbirth, live weak and small
small litter size

acute episode for 8 w, wanes for 4-6 w then gets lots of mummies

more sows not in pig due to early resorption

23

Q

what is the main pathogen of SMEDI?

A

porcine parvovirus - does not cause abortion!

25
Q

how does SMEDI affect different stages of production sows?

A

if not preg - immune

if preg - SMEDI

26
Q

how can you control SMEDI

A

vac 8w before service and 2 w before each following one as a booster
