Resumen

ABSTRACT

Objective. The aim of this field trial was to investigate the relationships among subclinical laminitis, hematological, ruminal and faecal alterations. Materials and Methods. To this extent dairy cows presenting subclinical laminitis (n=11) and to those of other healthy cows without laminitis (n=10) were enrolled and assigned into two groups. All animals were receiving the same daily ration formulated to contain 47% cornsilage and 18% hay, mainly. Effects of subclinical laminitis challenges on measurements of feces, and blood samples, were investigated to determine which of these measurements may aid in the diagnosis. pH changes in ruminal fluid collected via rumenocentesis were measured. Besides the following parameters were also measured; blood pH, faecal pH and faecal scoring. Blinded investigators performed the sample collection. Results. No statistical differences between the groups were detected for blood gas values studied regarding pCO2, HCO3, BE, indeed mean that pO2 values decreased statistically (p<0.05) and faecal pH was significantly decreased (p<0.05) in cows with subclinical laminitis in contrast to healthy controls. Conclusions. pO2 values and faecal pH may be valuable as indirect indicators of subclinical laminitis in cattle.

RESUMEN

Objetivos. El objetivo de esta prueba de campo fue investigar las relaciones entre la laminitis subclínicay alteraciones hematológicas, ruminales y fecales. Materiales y métodos. Las vacas lecheras que presentaron laminitis subclínica (n=11) y las vacas sanas sin laminitis (n=10) fueron reclutadas y asignadas en dos grupos. Todos los animales recibieron la misma ración diaria que contenía 47% de ensilaje de maíz y 18% de heno, principalmente. Los efectos de la laminitis subclínica sobre las mediciones de las heces y muestras de sangre, fueron investigados para determinar cuál de estas mediciones pueden ayudar en el diagnóstico. Se midieron los cambios de pH en el fluido ruminal recogido a través rumenocentesis. Además, también se midieron los siguientes parámetros; pH de la sangre, el pH fecal y la puntuación fecal. La toma de las muestras se realizó a doble ciego. Resultados. No se detectaron diferencias significativas entre los grupos para los valores de los gases sanguíneos estudiados en relación con la pCO2, HCO3, BE; lo que significa que los valores de pO2 disminuyeron estadísticamente (p<0.05) y que el pH fecal se redujo significativamente (p<0.05) en las vacas con laminitis subclínica; en contraste con los controles sanos. Conclusiones. Los valores de PO2 y pH fecal pueden ser valiosos como indicadores indirectos de la laminitis subclínica en el ganado.
