| dc.description.abstract | SUMMARY
The authors surveyed 52 pig fattening units (58,950 sows, 493,878 growing pigs
and fatteners) between March 2011 and October 2012 in Hungary in terms of
environment, management, housing, animal parameters and respiratory health
status including vaccinations applied against PRDC with the Respig Farm Audit
Tool™. Between April 2013 and April 2014 the audit was repeated in 15 swine farms
(16,524 sows, 166,491 growing pigs and fatteners). The environmental, management
and housing conditions pose a moderate risk in terms of PRDC and the fi nishing
facilities always had lower evaluations compared to the growing ones. Between
the two surveys the post-weaning ADG increased from 612 to 657 g/day, the FCR
decreased from 3.0 to 2.75, and the post-weaning mortality rate, including premature
disposal, also reduced from 8.90% to 8.60%. The animal health cost did
not change, amounted to €6.7-6.8/fi nisher. The most prevalent herd-level PRDC
pathogens were Porcine circovirus (93.2%; 100.0%), Mycoplasma hyopneumoniae
(90.4%; 100.0%) and Actinobacillus pleuropneumoniae (82.7%; 93.3%), but the
most severe was PRRSV in both examined periods. Refl ecting the prevalence
of PRDC pathogens the majority of swine herds vaccinated against PCV (75.0%;
86.7%) and M. hyopneumoniae (67.3%; 86.7%), however, none of them against
swine infl uenzavirus. | en_US |
