You are called by a feed technician in your company who has observed some unusual
symptoms at a company-owned 400 sow farrow to finish research herd. He is
concerned the signs could be related to the ration. The technician reports that the
herd feeds cracked high moisture corn, soy bean meal, dried distillers grains with
solubles and vitamin mineral premix. At the farm there is an increased incidence in
anestrus in some sows, persistent estrus in other sows and enlarged vulvas in gilts.
Which of the following choices is the most likely cause of these signs?
Give this one a try later!
High concentrations of Zearalenone in the feed
Of the following clinical disease problems in pigs, which does NOT have an FDA
labeled drug treatment?
Give this one a try later!
, Staphylococcus hycius
As part of the treatment and prevention program for post-weaning diarrhea due to
Escherichia coli, you attempt to find an Escherichia coli isolate in the herd that will
work as a "competitive exclusion" culture and interfere with the pathogenic
mechanism of the disease causing strain. You subject the isolates that you culture to
genotyping via PCR. Which of the following genotypes would be the best choice for
the competitive exclusion culture assuming the genotypes are expressed
phenotypically?
Give this one a try later!
Same pilus genes as the disease causing strain, no toxin genes
Bagley Pig Farm is experiencing a 12% abortion rate this week after a 2% rate last
week. There are no other clinical signs in the sows that abort. The manager suspects
PRRSV infection as the cause. What is the best diagnostic strategy to determine if
PRRSV is causing the abortions?
Give this one a try later!
Collect and pool the fetal thoracic fluid of 6 pigs from each of three
aborted litters and request PCR testing for PRRSV
Which of the following is the best definition of "parity?"
Give this one a try later!
, used to measure sow age and equal to the number of litters that the sow
has farrowed
A sow farm has brought in and bred new gilts to their current herd. Once these gilts
farrow, within 3-4 days the piglets become listless, depressed, and anorexic, and the
piglets' skin becomes reddened and lesions develop in the groin area. Brownish
spots, 1-2 cm in diameter and covered by serum and exudate begin to appear on the
skin of the face and head of the piglets. The lesions later turn from brown to black
crusts and enlarge and spread from the head posteriorly within 24-48 hours. The
youngest pigs are dying within 24 hours and others will survive 3-10 days. When
necropsied the piglets show evidence of dehydration and emaciation. The lymph
nodes draining the skin are swollen and edematous. Upon further examination of the
gross lesions the formation is odorous and crusty and below the crusty layer the skin
is grossly thickened and wrinkled. What is the most likely cause?
Give this one a try later!
Staphylococcus hyicus
You are called out to a 5,000 head sow farm in Iowa in December that has
experienced a large number of sudden reproductive losses. When you arrive at the
farm the farm manager shows you the farrowing room where all of the losses have
occurred. The sows had just been moved into farrowing and were due to farrow in a
day or two. The affected sows have had entire litters born dead, but appear full-term
and otherwise normal. You do not appreciate any gross lesions in piglets. No other
sows on the farm are affected. The manager is very concerned because they had a
huge number of late-term abortions two winters ago and last time it "took months for
everything to cool down" and start weaning normal, healthy pigs again. What is the
most likely cause of the current losses on the farm?
Give this one a try later!
, High levels of carbon monoxide resulted in fetal death and pregnancy loss

Chapter 66—Coccidia and Other Protozoa
A young swine producer and his wife have just taken over management of a 800 head
farrow to finish farm. They pride themselves on efficient management and high
standards of animals health and welfare. You see evidence of this in every aspect of
their farm, but one area of contention you have with them is rodent control. Their
solution to this seems to be founded on a hearty feline population that roams the
farm. The producers frequently save back one pig at marketing time for their own
consumption. Given this scenario, which disease poses their biggest zoonotic health
risk?
Give this one a try later!
Toxoplasma gondii
Which of the following would NOT typically be considered part of the "core" or
standard vaccination program for a typical reproductive herd?
Give this one a try later!
Transmissible gastroenteritis virus (TGE)
