Impact of strategic control of Rhipicephalus (Boophilus) microplus on the productive indices of breeding herds in Formosa Argentina

The cattle tick Rhipicephalus (Boophilus) microplus is the most significant ectoparasite affecting cattle production in northeastern Argentina (NEA), as it negatively impacts both animal productivity and health. This study evaluated the implementation of a strategic tick control program in a breedin...

This study evaluated the implementation of a strategic tick control program in a breeding herd in Formosa Province and its effect on productive performance indices. A total of 120 cows were monitored and assigned to two experimental groups: Group I (treated) and Group II (control). The treated group received a therapeutic regimen consisting of 2.5% fluazuron, 3.15% ivermectin, and 1% fipronil. Which were maintained under similar pasture conditions throughout the study period (198 days). Tick control efficacy exceeded 90%, except on days 54 and 167 (83% and 79.5%, respectively). Significant differences in tick burden were observed between groups (p≤0.05). In the treated group, the pregnancy-to-weaning loss rate was 5%, and the pregnancy rate reached 84.7%. The findings indicate that the application of a strategic control program did not result in productivity losses associated with animal handling or corral movements, while effectively reducing parasitic losses and contributing to the sustainability of cattle production in the region. La garrapata común del bovino, Rhipicephalus (Boophilus) microplus, es el ectoparásito de mayor importancia en la producción bovina del Noreste Argentino (NEA), ya que impacta negativamente en la productividad y sanidad animal. Este trabajo evalúa la aplicación de un esquema de control estratégico de garrapatas en un rodeo de cría en Formosa y su impacto en los índices productivos. Se monitorearon 120 vacas distribuidas en dos grupos experimentales: grupo I (tratado) y grupo II (control). El grupo tratado recibió un esquema con fluazurón 2,5%, ivermectina 3,15% y fipronil 1%. Las mismas fueron mantenidas durante todo el seguimiento (198 días) en potreros con condiciones similares. En cuanto a los niveles de eficacia observados, estos fueron superiores al 90% con excepción de los días 54 y 167 (83%-79,5%, respectivamente). Hubo diferencias significativas en la carga de garrapatas entre grupos (p≤0,05). En el grupo I, el porcentaje de pérdida preñez - destete fue de 5% y el porcentaje de preñez 84,7%. Los resultados indican que la aplicación de control estratégico no generó pérdidas productivas asociadas a los movimientos a corral y manejo de los animales, y permite reducir las pérdidas asociadas a la parasitosis y contribuir a la sostenibilidad de la actividad ganadera en la región.
