Antibody response to the vaccinationsAntibody titres against H. somni (Hs), P. multocida (Pm), and M. haemolytica (Mh) in (1) the first experiment and (2) the second experiment. Calves received (1) the primary vaccination at the age of 5–12 days and the booster dose at 2, 3 or 4 weeks later or (2) the primary vaccination at 1, 2 or 3 weeks of age and the booster dose at 4 weeks later. (1) In control group calves, blood was drawn at the age of 5–12 days and calves received the vaccination only once 2 weeks later (between 19 and 26 days of age). A, B – P < 0.01; a, b – P < 0.05; arrows – time of vaccination
