Aplicación de un plan de control para campylobacteriosis genital bovina en un establecimiento de cría con pérdidas reproductivas en el departamento de Pichi Mahuida

Abstract

This work addresses the implementation of a control plan against Bovine Genital Campylobacteriosis (BGC) in a cattle breeding establishment in the Pichi Mahuida department, in the province of Río Negro. The study arises as a response to significant reproductive losses in the herd, caused mainly by this venereal disease, characterized by its negative impact on reproductive and economic efficiency. BGC, caused by Campylobacter spp., affects fertility by causing repeated estrus, embryonic death and abortions, which translate into a longer service season. The control plan included pre- and post-service diagnoses, sampling of bulls, elimination of infected individuals, adjustments in the duration of the service season, and systematic records of reproductive indicators. Variables such as pregnancy percentages, pregnancy distribution, reproductive losses, calving and weaning percentages were evaluated; using tools such as digital rectal examination, ultrasound and laboratory analysis. The result of the implementation of the control plan was the absence of reproductive losses in the cycle under study, compared to 33% of reproductive losses in the previous cycle, highlighting the effectiveness of the sanitary and reproductive strategies applied, although challenges related to the comprehensive management of the herd persist.
