  1. Which vaccination strategy is most effective for controlling Mycoplasma hyopneumoniae in a continuous-flow growing facility?

    Answer: Two-dose piglet vaccination at 1 and 3 weeks of age

    A two-dose vaccination protocol starting at 1 week of age provides optimal protection against M. hyopneumoniae-associated enzootic pneumonia in growing pigs.

  2. In swine biosecurity, what does 'all-in/all-out' (AIAO) flow primarily prevent?

    Answer: Pathogen cycling between older and younger age groups

    AIAO management prevents older, infected pigs from continuously exposing younger, naïve pigs to pathogens, breaking disease transmission cycles.

  3. Post-weaning multisystemic wasting syndrome (PMWS) is primarily associated with which pathogen?

    Answer: Porcine circovirus type 2 (PCV2)

    PMWS is primarily associated with PCV2, causing wasting, lymphadenopathy, and immunosuppression in post-weaned pigs.

  4. Which disinfectant class is most effective against porcine parvovirus due to its non-enveloped nature?

    Answer: Glutaraldehyde or bleach (sodium hypochlorite)

    Non-enveloped viruses like PPV are resistant to many disinfectants but are susceptible to aldehydes and oxidizing agents like sodium hypochlorite.

  5. What is the primary route of transmission of African Swine Fever (ASF) virus in swine herds?

    Answer: Direct contact with infected pigs and contaminated feed/fomites

    ASF spreads primarily through direct contact with infected pigs and indirect contact via contaminated feed, equipment, and personnel (fomites).

  6. Greasy pig disease (exudative epidermitis) in suckling piglets is caused by which organism?

    Answer: Staphylococcus hyicus

    Staphylococcus hyicus produces exfoliative toxins that cause greasy pig disease, characterized by generalized seborrheic dermatitis in neonates.

  7. Which reproductive parameter best reflects overall female productivity in a commercial swine operation?

    Answer: Number of pigs weaned per sow per year (PSY)

    PSY (pigs weaned per sow per year) integrates farrowing rate, litter size, pre-weaning mortality, and number of litters per year into a single productivity metric.
