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.
