Abstract This experiment was carried out to investigate the effect of vaccination during lactation with PorciW Ery+Parvo on the weaning-to-oestrus interval and the reproduction in sows. An exploratory study had indicated that vaccination during particularly the first few days of lactation might lead to a longer weaning-to-oestrus interval. To find out whether vaccination during lactation and/orthe moment of vaccination actually affects the weaning-to-oestrus interval, sows were vaccinated the first, second or last weeks of lactation with either Porcilis@ Ery+Parvo or a placebo. In the same experiment the combination with induced parturition on the weaning-to-oestrus interval was examined. Also the influence of the treatments on the use of PGGOO@ was considered, as was pregnancy rate from first insemination and litter size, and the number of stillborn piglets or born alive in the subsequent litter. The main results and conclusions are: 1- Vaccination of sows during the first week of lactation (with PorciW Ery+Parvo) against Swine erysipelas and Parvo has no significant adverse effect on reproductive performance. 2- Induced parturition causes earlier parturition, which results in lighter piglets. Induced parturition has no effect on percentage of piglets born alive; the percentage of piglets with splay leg is significantly higher
