Modern startup farms may have less pressure of respiratory diseases infection in winter as they usually have good ventilation design. However, the clinical case described here is an App outbreak in a startup farm with modernized ventilation design.
Nitrite poisoning does still occur in modern pig facilities, even more with the presence of the biological air treatment.
The farmer contacted the veterinary surgeon concerning an increase of subcutaneous haemorrhages and bruises in the skin of several piglets in eight different litters. No deaths have yet been attributed to the problem.
Weaning is a critical event in the pig’s life. It is a very important and stressful transition that, if not handled properly, can be responsible for the occurrence of diarrhoea and/or poorly adapted piglets.
Once the first symptoms of the infection emerged in pigs the facility was locked and the possibility to get in from outside was the only used.
This article shows the different measures taken and the strategy followed to eradicate PEDv in a commercial farm: stabilization, creation of a disinfection bubble, monitoring and verification.
We were called for clinical problems on weaners that appeared a few days after a feed transition in a farrow-to-finish farm: swelling of the eyelids and forehead, incoordination, dyspnea and sudden death.
The owner contacted us because he has seen a reduction in performance in recent months, although no decline has been identified in any particular parameter. He says that, overall, “the sows are doing worse".
This case report highlights the importance of a comprehensive approach to achieve a correct differential diagnosis.
