Abstract

When piglets fail to receive colostrum from the sow, as an alternative means passive immunization can be carried out with antibodies derived from non-maternal sources. In this study, pregnant cows were vaccinated intramuscularly and intramammarily with killed ETEC vaccine and developed a high level of colostral antibodies. These antibodies were specifically of IgG and IgA. Day-old piglets fed with colostrum containing a high titre of IgG survived the challenge infection. However, 75% piglets fed with colostrum from unvaccinated cows, and 100% piglets receiving no colostrum, died from challenge infection.
