Weight gain in vaccinated animals. Three-week-old pigs were divided into four groups. Animals from two groups were vaccinated with 10⁶ TCID₅₀/animal of rTGEV-RS-SPEDV virus (red) or a virulent US PEDV strain (PEDV-NVSL, green). Three weeks after vaccination (21 dpv indicated in red), non-vaccinated animals were either mock infected (Mock, grey) or challenged with 10⁷ TCID₅₀/animal of a virulent PEDV strain (Non Vaccinated, black). Vaccinated animals were also challenged with the same dose as non-vaccinated animals. Clinical signs and weight were observed daily after vaccination and challenge, and once per week during the course of the experiment. Average daily gain represents the mean from six different animals. Error bars represent the standard deviation for each value; p value, ** <0.01.
