  • Title: The effect of vaccination against Leptospira interrogans serovar hardjo infection at the time of service on pregnancy rates in dairy cows.
    Author: Dhaliwal GS, Murray RD, Downham DY, Dobson H.
    Journal: Vet Res; 1994; 25(2-3):271-4. PubMed ID: 8038799.
    Abstract:
    Fertility data from 16 dairy herds vaccinated against hardjo infection were used to assess pregnancy rates in cattle vaccinated around the day of mating. There was no improvement in pregnancy rates 30-60 d after vaccination. Pregnancy rates in the period 5 d before and 10 d after vaccination were statistically lower than those found in 30-60 d around vaccination.
