OCCURRENCE OF ABORTIONS AND SEROPREVALENCE OF BRUCELLOSIS IN GOATS AND SHEEP

Occurrence of abortions, still births and seroprevalence of brucellosi s were studied in native, unvaccinated and organised flocks of goats ( Barbari, Jamunapari, Sirohi, Kutchi, Jakharana, and Marwari) and sheep (Muzaffarnagri) with abortion problems during the period from 1985 to 1990. In 6 years, 8.4% lambs and 13.4% kids were lost due to abortion s and still births. Incidence of abortions were recorded as 12.3% and 6.8% and still births 1.0% and 1.6% in goats and sheep, respectively. Serologically, 0.6% goats and 3.6% sheep were found to be positive for brucellosis by standard tube agglutination test (SAT). The regular sc reening of the flocks for Brucellosis and elimination of positive case s partially helped to lower the incidence of Brucellosis in these floc ks.
