(148 cards)
Which of the following tests is a measure of stress immune function in swine?
- Alpha-1 acid glycoprotein
- Alkaline phosphatase
- Creatine phosphokinase
- Alpha mannosidase
- Sorbital dehydrogenase
α1 acid glycoprotein (AGP)

Noisy, anxious day-old pigs probably indicate:
- Heat stress
- Cold stress
- Hunger
- Endotoxemia
- Bacteremia
Hunger

What is your diagnosis for the skin condition shown on these pruritic pigs?
- Ringworm
- Parakeratosis
- Sarcoptic mange
- Vitamin A deficiency
- Greasy pig disease

Sarcoptic mange
- Hypersensitivity reaction to mite
- Sensitization takes place over several weeks
- Crusting and pruritis develop

Identify this breed:

Vietnamese Pot-belly

What is your diagnosis of this piglet whose skin was covered with exudate?
- Ringworm
- Parakeratosis
- Greasy pig disease
- Vitamin A deficiency
- Papillomatosis

Greasy pig disease
I would also remember the stupidly small picture below ;)

A 7 week old Pot-bellied Pig is presented with a posterior swelling that looks like this. Which one of the following is the most likely clinical diagnosis?
- Perineal hernia
- Inguinal hernia
- Testicular torsion
- Cryptorchidism
- Intersex syndrome

Inguinal hernia
- A COMMON problem in pigs, Rx surgically: midline skin incision, cranial to scrotum; ligate and excise vas deferens, blood vessels.*
- (Zuku or VetPrep question)*
T/F: Salmonella choleraesuis and Salmonella typhimurium are both treated with Oxytetracycline
False
- Salmonella choleraesuis is treated with Oxytetracycline.
- Salmonella typhimurium is resistant to Oxytetracycline (as well as most other antibiotics allowed in food animals)

Swine pox is transmitted by:
- Culicoides varipennis
- Ixodes ricinus
- Stomaxys calcitrans
- Boophilus annulatus
- Hematopinus suis
Hematopinus suis
Haematopinus suis is also known as the hog louse
- Swine Pox is associated with CUTANEOUS Lesions
-
Transmitted by virus contact associated with skin injury
- The hog louse acts as a mechanical vector – may carry the virus for weeks or months
- Pigs usually recover without problems

Before sows are moved into the farrowing crates they should be:
- Flushed with a high energy ration
- Flushed with a high calcium and protein ration
- Medicated with a broad spectrum antibiotic to help sterilize the intestinal tract and prevent coliform buildup in the environemt
- Vaccinated against tuberculosis
- Washed to remove dirt and parasite eggs
Washed to remove dirt and parasite eggs
The probability for swine influenza occurring in animals reared in confinement on concrete should be less than in animals raised on soil because:
- Concrete can be effectively disinfected
- Pigs raised on concrete retain colostrum derived immunity for a longer period
- Contact with the virus via earthworms is reduced
- Concrete has recently been shown to have viricidal properties
- Contact with the virus via ascarids is reduced
Concrete can be effectively disinfected
Mange in swine can be diagnosed by the vacuum cleaner filter sampling technique. A drug which is useful for treatment of mange is:
- Fenbendazole
- Ivermectin
- Thisbendazole
- Sulfamethazine
- Monensin
Ivermectin

Why is a uniform microenvironment important in a pigpen?
- Water consumption increases
- Need for vaccination is reduced or eliminated
- Feed conversion is better
- Tendency to fight is reduced
- Immune function is improved
Tendency to fight is reduced

The etiology of pityriasis rosea in swine is:
- Fungal
- Bacterial
- Viral
- Neoplastic
- Undetermined
Undetermined
Pityriasis rosea is a sporadic disease of unknown etiology of pigs, usually 8–14 wk old, but occasionally as young as 2 wk and very rarely in pigs as old as 10 mo

Which of the following viral diseases below affects only swine?
- Vesicular exanthema
- Foot and Mouth Disease
- Vesicular stomatitis
- Rinderpest
- Malignant Catarrhal Fever
Vesicular exanthema
Vesicular exanthema does not affect cattle, sheep, goats or any species other than the pigs (and sea mammals). So, unlike FMD, if you keep other livestock they will not be affected. However, keep in mind that it produces a disease in pigs that is clinically indistinguishable from FMD.

Which one of the following clinical signs occurs most commonly in pigs affected with PMWS?
- Sudden death
- Depression
- Inappetance
- Pale mucous membranes
- Peripheral lymphadenopathy
Peripheral lymphadenopathy
T/F: Addition of conjugated linoleic acid to grow-finish diet at the rate of 1% increases average daily gain and improves feed efficiency while cutting market hog backfat levels by 20%
True

Tail biting in swine may cause abscesses in the spine due to:
- Actinomyces pyogenes
- Lawsonia intracellularis
- Bordetella bronchiseptica
- Erysipelothrix rhusiopathiae
- Mannheimia hemolytica
Actinomyces pyogenes
I think this is now called Trueperella pyogenes
Bull nose in swine is caused by the organism:
- Bordetella
- Shigella
- Fusobacterium
- Treponema
- Salmonella
Fusobacterium necrophorum
Necrotic rhinitis is an uncommon, sporadic disease of young pigs characterized by suppuration and necrosis of the snout, arising from wounds of the oral or nasal mucosa
In the southern United States neonatal swine may be affected with which one of the following parasites if a rigid control program is not followed?
- Threadworms
- Roundworms
- Whipworms
- Kidney worms
- Stomach worms
Threadworms
Strongyloides; can be passed through placenta and colostrum and can kill piglets!

On most pig farms today piglets are weaned at what age?
- 5 days
- 10 days
- 15 days
- 3 weeks
- 2 months
3 weeks

A commercial pig farm experiences an explosive outbreak of respiratory disease with high mortality, primarily in young pigs under 6 months of age.
Affected pigs show severe respiratory distress, fever up to 107°F (41.5°C), anorexia, and reluctance to move. Some animals display open-mouth breathing with a blood-stained, frothy nasal and oral discharge.
On necropsy, the lungs are bilaterally dark and swollen and ooze bloody fluid from the cut surface.
Which one of the following choices is the most likely diagnosis?
- Actinobacillus pleuropneumoniae
- Fusobacterium necrophorum
- Mycoplasma hyopneumoniae
- Haemophilus parahaemolyticus
- Swine influenza

Actinobacillus pleuropneumoniae
- This is a classic scenario of an outbreak of pleuropneumonia, caused by Actinobacillus pleuropneumoniae*
- (Zuku or VetPrep Question)*
These animals are all the same age. They have been raised together. Which one of the following diseases is probably associated with this?
- Erysipelas
- Tuberculosis
- Leptospirosis
- Ileitis
- Ascariasis

Ileitis
Lawsonia intracellularis is a Gram [+] organism responsible for causing porcine ileitis (and wet tail in hamsters). One of the main clinical signs is uneven growth - some look normal and some look stunted.
Test and slaughter is the usual method of control for which one of the following diseases in both cattle and hogs?
- Leptospirosis
- Brucellosis
- Corona virus
- Spongiform encephalopathy
- Campylobacter
Brucellosis
Modified medication early weaning programs have been useful in elimination of many pathogens from piggeries. Which one of the following diseases is a good example of this?
- Mycoplasmosis
- Creeper syndrome
- Eubacterium
- Brucellosis
- Splay leg
Mycoplasmosis
