What are the signs of vibriosis?
Top The initial indication of a vibrio infection in a herd is cows returning to service and low pregnancy rates. Poor conception rates, especially in heifers, are often seen after the introduction of an infected bull. In newly infected herds conception rates can be as low as 40%. Permanent infertilty may occur due to damage to the reproductive tract. In a vibrio outbreak, a high proportion of females may not return to service for 3 to 5 months. Sporadic abortions can occur commonly 5 to 7 months into pregnancy. Infected bulls show no obvious signs but can act as long-term carriers, infecting cows and heifers at service. Vibriosis causes significant reproductive losses especially in the first year of infection.
