Abstract

ALFIERI, Amauri Alcindo; LEME, Raquel Arruda; AGNOL, Alais Maria Dall  and  ALFIERI, Alice Fernandes. Sanitary program to reduce embryonic mortality associated with infectious diseases in cattle. Anim. Reprod. [online]. 2019, vol.16, n.3, pp.386-393.  Epub Nov 28, 2019. ISSN 1984-3143.  http://dx.doi.org/10.21451/1984-3143-ar2019-0073.

Among reproductive disorders in dairy and beef cattle worldwide, embryonic mortalities stand out as one of the most frequent. Because of the multifactorial etiology, the clinical and laboratory diagnoses of embryonic mortality causes in cattle are quite complex. Often, infectious causes may account for up to 50% of bovine embryonic mortality rates after 30 days of conception. This review will address the main causes of early and late embryonic mortality, with emphasis on infectious causes and, particularly, those more frequent in the Brazilian cattle herds. In addition, we will discuss ways of controlling and prophylaxis including those related to reproductive and sanitary management, with emphasis on immunoprophylaxis of the three most frequent reproductive infectious diseases in Brazilian dairy and beef cattle herds.
