Abstract
BackgroundSevere outbreaks of interdigital phlegmon (IP) associated with a high morbidity and major economic losses have occurred in Finland in the past decade. A survey was performed to indicate the current occurrence of infectious hoof diseases and to identify herd level risk factors predisposing to an outbreak of IP.ResultsResponses to a questionnaire revealed that an outbreak of IP defined as morbidity ≥5% within the 1st month of the outbreak, had occurred in 18.0% of the respondent study farms. Risk factors for an outbreak included animal transport between herds, i.e. either animal purchase or contract heifer rearing, enlargement or renovation of the barn, and if the fields of the farm had been organically cultivated. Having any kind of mechanical ventilation in comparison to natural ventilation seemed to lower the risk of IP. Additionally, the farms that had experienced an outbreak of IP often had other infectious hoof diseases. However, it was unclear which disease appeared first.ConclusionsMore attention is needed before and during enlargement or renovation of the barn and substantial planning is crucial for every part of the enlargement process in dairy farms.
Highlights
Severe outbreaks of interdigital phlegmon (IP) associated with a high morbidity and major economic losses have occurred in Finland in the past decade
Eighteen percent of the herds who responded to the questionnaire in our study were diagnosed as having an outbreak of IP with morbidity ≥5% within the 1st month of the outbreak, whereas 9.0% of the herds who reported having sporadic cases of IP did not fulfill our definition of an outbreak
A study from the Netherlands reported that the presence of other infectious hoof disorders, such as interdigital dermatitis and heel horn erosion (IDHE) and IP, increased the risk for DD, and IP appeared to be strongly associated with DD (OR = 4.4) [17]
Summary
Severe outbreaks of interdigital phlegmon (IP) associated with a high morbidity and major economic losses have occurred in Finland in the past decade. A survey was performed to indicate the current occurrence of infectious hoof diseases and to identify herd level risk factors predisposing to an outbreak of IP. Several dairy herds in Finland experienced a sudden outbreak of interdigital phlegmon (IP). These outbreaks mainly occurred in recently built or renewed free stall barns and caused major economic losses due to high morbidity, antibiotic treatment of the affected cows and discarded milk [1]. Only a few cases of infectious hoof diseases were detected in Finnish dairy farms. Several new techniques have been introduced in the farms, like mixed ration feeding and automatic milking system
