abstract = "In Serbia, there are different animal production systems, including extensive ones, which are
common and traditional in Serbia. Nowadays, extensive pig production with very low or almost
no biosecurity measures plays an important role in the spread of ASF and other infectious
diseases. Extensive farming systems are traditionally practiced in villages, hamlets, and forests,
usually near riverbanks. In Serbia, there are different types of extensive production systems:
small farms, backyards, semi-free-range, free-range, and a small percentage of organic pig
production units. In traditional systems, pig production can also be divided into indoor and
outdoor housing. However, it is not easy to make a clear distinction between extensive indoor
and outdoor units. In traditional backyard housing systems, pigs are not confined to the units at
all times, and often there is no complete fencing. According to Serbian law, disease surveillance
is mandatory in all pig production. However, local veterinarians are mainly focused on the control
and diagnosis of transboundary infectious diseases such as ASF and CSF. For these reasons, many
other parasitic, bacterial, and sometimes viral infections are detected but underestimated.
During 2019-2023, we retrospectively analyzed the most common diseases in pigs from
traditional extensive husbandry necropsied in the Institute of Veterinary Medicine of Serbia and
the Scientific Veterinary Institute "Novi Sad". Among the most common parasitic diseases in pigs
in extensive husbandry are ascariasis and trichurosis. As for bacterial pathogens, Escherichia coli
and enteric clostridial infections, Pasteurella multocida, Glaesserella parasuis, Streptococcus spp.,
and Salmonella spp. were the most frequently isolated bacteria from various organs of the
examined pigs. The viral pathogens most commonly detected were suid herpesvirus 1 (Aujeszky's
disease) and porcine parvovirus (PPV), in addition to ASF, which was confirmed in infected
counties nationwide. Low biosecurity measures or lack of external biosecurity measures in
extensive swine production farms pose a high risk for transmission of various pathogens,
including not only diseases caused by conditionally pathogenic microorganisms, but also
notifiable diseases that can have a significant negative impact on the country's economy.",
