Speed V-DiarTM enables the rapid identification, in only 15 minutes, of the causative agents of neonatal diarrheas.

Simple, Speed V-DiarTM does not require any specific equipment. It can be undertaken during an on-farm visit and gives an immediate result.

Stable, Speed V-DiarTM can be stored for 18 months room temperature, between 2°C and 30°C

Why use Speed V Diar TM ?

Neonatal diarrhea is the principal cause of mortality and growth retardation in calves under 1 month of age. They represent more than 25% of the reasons for consultation on farms (2). Due to the similarities seen in the symptoms between bacterial, viral, or parasitic diarrheas, laboratory identification is essential.

Furthermore, associations of various different pathological agents are common.
A precise etiological diagnosis enables a specific treatment protocol to be instigated at the farm and adapted preventive measures throughout the calving season.

When use Speed V Diar TM ?

Speed V-DiarTM can be used to determine which pathological agents are implicated in calf diarrhea. The Speed V-DiarTM test is carried out from the first signs of diarrhea, before any form of treatment is administered.

On a larger scale, Speed V-DiarTM can be used to identify the pathological agents that are present on the farm from the first few cases of diarrhea in the calving season. This identification enables the instigation of appropriate sanitary and prophylactic measures.
