Table 1.

Statistical probability of survival of 14–16-day-old nursing piglets at 11 d post-challenge with active PED virus.

Treatment	Probability	Groupings
INJ	0.26	ab
CON	0.09	a
LOV	0.56	b
HOV	0.08	a

Dams were given an injected PEDV vaccine (INJ; n = 4), a low-dose oral PEDV vaccine (LOV; n = 4), a high-dose oral PEDV vaccine (HOV; n = 4), or served as non-vaccinated controls (CON; n = 4) during pregnancy. The probabilities were computed assuming piglets of average weight. Values with different letters (a, b) p ≤ 0.05.
