Umbilical outpouchings in pigs - an international survey on fitness for transport, welfare and management.

BACKGROUND

Umbilical outpouchings (UOs) in pigs are a multifactorial disease and little is known about effective prevention strategies and risk factors for UO development. UOs are common in Danish pigs and legislation complicates and increases the cost of keeping and raising pigs with UO. Recommendations for preventive measures exist but the scientific evidence behind the recommendations is often lacking. This study´s purpose was to investigate veterinarians' perspectives on UO pigs´ fitness for transport, the welfare of UO pigs, the significance of UO, risk factors for the development of UO, and the management of pigs with UO. This study´s purpose was to investigate veterinarians' perspectives on UO pigs´ fitness for transport, the welfare of UO pigs, the significance of UO, risk factors for the development of UO, and the management of pigs with UO.

RESULTS

The survey received 93 complete responses from veterinarians working within porcine health management. Because of the large proportion of replies from Danish veterinarians, all reporting of results was divided among Danish and non-Danish veterinarians. There were no statistically significant differences between the two groups in the assessment of fitness for transport. Both groups mainly agreed to a series of statements regarding the significance of UO and risk factors for UO development. The management of UO was also similar across the groups except for the use of neonatal antibiotics which was used considerably more in Danish herds.

CONCLUSIONS

Umbilical outpouchings seem to be perceived as a challenge across pork production; affecting the welfare of the individual pig as well as the management of the entire production. There were no significant differences between Danish and non-Danish veterinarians' assessments of fitness for transport, and almost all the veterinarians agreed that some UO pigs might need special attention and care. Most would also recommend preventive measures. Despite most respondents in this survey working under the laws of the European Union, some were unaware of legislation regarding UO pigs.
