Counts per million aligned to each viral gene in the challenged Fayoumi and Leghorns at 2 dpi. The NDV genes are listed in the order nucleoprotein (NP), phosphoprotein (P), matrix protein (M), fusion protein (F), hemagglutinin-neuraminidase (HN), and large polymerase protein (L). The least-square means of the counts per million are shown for the challenged Fayoumis (n = 4) and Leghorns (n = 5). Error bars represent standard deviations of the means. The connecting letters report was generated with a Student t test.
