Abstract

The present study was conducted to investigate the effects of time of vaccination in recipients on the pregnancy rate and the viability of calves derived from embryos produced in vitro. In experiment 1, control group was non-vaccinated, group 1-1 received vaccine (Pfizer, Exton, PA, USA) during 0$sim$4 weeks and group 1-2 received vaccine during 4$sim$8 weeks before embryo transfer. The pregnancy rates in the control (42.6%) and group 1-2 (45.3%) were significantly higher (p<0.05) than that in the group 1-1 (32.6%). However, the abortion rates were similar among groups (4.9 to 13.5%). In experiment 2, the recipients received embryos produced in vitro were non-vaccinated (control) or vaccinated. Vaccine was injected during 0$sim$4 weeks (group 2-1) and 4$sim$8 weeks (group 2-2) before parturition. The incidence of a disease in calves was significantly higher in the control (22.4%) than in other vaccinated groups (2.2% and 3.1%, p<0.05). The mortality of calves in the control is 27.6%, which was significantly higher than that of group 2-1 and group 2-2 (11.1% and 7.8%).
