Ileitis in growing pigs caused by Lawsonia intracellularis most commonly presents in which form in nursery-age pigs?
Answer: Porcine intestinal adenomatosis (PIA)
Porcine intestinal adenomatosis (PIA) is the most common form in younger pigs, causing chronic diarrhea and poor growth, while PHE occurs more in older/finishing pigs.
What pen space allowance (sq ft per pig) is generally recommended for finishing pigs weighing 100–125 kg in North American operations?
Answer: 7–8 sq ft
Standard North American guidelines recommend approximately 7–8 sq ft per pig for finishing pigs at market weight to reduce aggression and support performance.
Which clinical sign most strongly suggests Glässer's disease (Haemophilus parasuis) in nursery pigs?
Answer: Polyserositis with fibrinous pericarditis, peritonitis, and pleuritis
Glässer's disease is characterized by polyserositis (fibrinous inflammation of multiple serous membranes) along with arthritis and meningitis in stressed nursery pigs.
In boar management, what is the recommended minimum rest period between semen collections to maintain optimal sperm quality?
Answer: 48–72 hours
Boars should rest 48–72 hours between collections to allow epididymal sperm reserves to replenish and maintain optimal motility and morphology.
What is the primary purpose of strategic antibiotic metaphylaxis in swine production?
Answer: To prevent disease in high-risk animals before clinical signs appear during a defined risk period
Metaphylaxis involves treating a high-risk group (e.g., newly weaned pigs post-transport) before or at the onset of disease to prevent clinical illness during the risk period.
Swine dysentery caused by Brachyspira hyodysenteriae is characterized by which type of diarrhea?
Answer: Mucohemorrhagic diarrhea in growing/finishing pigs
Swine dysentery causes mucohemorrhagic colitis in growing and finishing pigs, resulting in bloody, mucoid diarrhea and significant production losses.
Which internal parasite control strategy is most effective in a modern, confinement swine operation?
Answer: Strategic deworming of sows before farrowing and treating all new introductions
Strategic deworming of sows 1–2 weeks before farrowing prevents larval transfer to piglets and treating new animals before entry prevents introduction of new parasites.
