This behaviour was believed to be due to a nutritional deficiency in the sows (not substantiated). Sows are more likely to try and break the creep box to use as nesting material. The use of creep boxes was much better in Quang Tri than Hue. • There is still some confusion as to the use of ordinary light bulbs as a heat source for piglets and lactating sows. • Many farms had wet floors in the pens which might have been due to farmers cleaning them before our visit. The weather was mostly wet (drizzle) and cool which meant pens would take longer to dry. • I was not aware of any monthly farm audits being conducted during my time in Vietnam.

However, it might have been due to the commune paraveterinarian selecting these farms for the trial and that these farms had sows at the correct stage of pregnancy when vaccination was carried out. Although CARD project farms would also have had sows in late pregnancy. • The other main issue was that faecal sampling of piglets was undertaken at the wrong time (age of piglet).
