Antibody titers of ALV-A in the sera of the chickens, quails and pigeons on different days post infection with ALV-A strain. *P < 0.05 between two groups; Number of chickens is 10 (ALV-A group) and 6 (control group); Number of quails is 12 (ALV-A group) and 6 (control group); Number of pigeons is 10 (ALV-A group) and 6 (control group); the line with arrow means the cut off of antibody titers (S/P = 0.4).
