Effects of N. sativa on ND antibody titer of broilers: T0 = control 1 (without vaccination and without supplementation of N. sativa in diet), T1 = control 2 (T0 + vaccination), T2 = T1 +N. sativa 0.5%, T3 = T1 + N. sativa 1%, T4 = T1 + N. sativa 2%, T5 = T1 + N. sativa 4%, T6 = T1 + N. sativa 8%, and T7 = T1 + N. sativa 16%. Different alphabetical letters indicate significant () differences between the means of the groups.
