Abstract

Aphthus fever or Foot-and-mouth disease (FMD) is a highly contagious and serious viral disease of animals. It affects animals with cloven-hoofed including cattle, buffalo, camels, sheep, goats, deer and pigs. Africa, the Middles East, Asia and South America were between the countries whom report the disease. High losses of milk and meat production could be occurred due the infection and, affect the trade in livestock and livestock products.

Twenty unvaccinated dairy cows with foot and mouth vaccine and their newborn calves were included in this study to investigate about the effects of their infection with foot and mouth disease virus. The results were revealed high severity clinical signs as weakness, loss of milk production, mastitis with appearance of blisters on teats, lameness, cough, rough coat and sings of panting. Also the study was investigates about the fate of their newborn calves which were mostly dead from the infection through vertical transmission of the virus with lactated milk or owners.

In recommendation, in order to maintain the flock from FMDV, annual vaccination with FMD vaccine contain endemic strains A, O and Asia (Shamir).
