EVALUATION OF THE PRESENCE OF COLOSTRAL ANTIBODIES IN PIGLETS OF DIFFERENT AGE ORIGINATING FROM SOWS VACCINATED WITH CHINA CLASSICAL SWINE FEVER VIRUS
Since the placenta is multilayered, there is no transfer of maternal antibodies into the pig fetal circulation, so passive immunity is completely acquired by post-farrowing colostral intake. When speaking about investigation of maternal immunity, the problem of lasting colostral protection of pigle...
