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? - ANSWERSToxoplasma gondii
Of the following primary pathogens that affect pigs, which one is least likely to be
adequately prevented or controlled with a vaccination program? - ANSWERSPRRSV
Your swine practice has a 10% contingent of clients with non-conventional management
systems, such as outdoor/pasture housing. One of these clients has been 50 sows and
4 boars, all of which practice natural breeding. This producer has been having
increased numbers of sows returning to estrus after breeding. There are few other
clinical signs noted, with the current herd in good health and body condition other than a
decreased reproductive performance. The only thing you have noted is an increases
occurrence in the boars of granulomas and absecesses, and one boar had edematous
testicles for a few weeks. However, you have attributed those signs in the boars to the
fact that they are housed together and occasionally tussle with each other. You have
submitted herd serology and tissues from two litters that aborted in the past 6 months,
finding negative test results for PRRSv, Porcine parvovirus, and leptospirosis. Assum -
ANSWERSBrucella suis
Which of these postures suggests that the effective temperature is more likely too cold
for the pigs than too warm? - ANSWERSSternal with legs tucked underneath
You are called to a 2400 head breed to wean farm that has been experiencing an
increased number of piglets that are falling behind immediately after birth. Two
farrowing rooms in particular at one end of the building are affected. The piglets in these
rooms are born with no dystocia and in numbers average for the industry, but fail to
, thrive the first 3-4 days of life. When you examine the piglets, you can see they have a
gaunt appearance, are underweight for their age, remain close to the sow even when
not feeding, and some minor diarrhea is noted. Before examining the females, you run
through a list of differentials. Which of the following factors is least likely to be
influencing the females' poor milk production? - ANSWERSHigh levels of fiber in the
lactation feed
Which of the following values are NOT CORRECT and would not represent
expectations for normal biological performance for the associated parameter? -
ANSWERSFinisher daily weight gain =4.9#
You are called to investigate a group of sick pigs that have just recently been placed in
the nursery. They had a delayed arrival due to traffic problems from the inclement
January weather. Almost 20% of these piglets are anorexic, thin, and sneezing. Most of
the piglets are piled together in groups. Approximately 5% of the group has been pulled
to the sick pen because severe dyspnea and neurologic signs that range from unsteady
walking to lying on the pen floor and paddling. So far about half of the severe cases
respond to intensive care and treatment with ceftiofur crystalline free acid. Your
diagnostic workup includes a necropsy of mortalities and a culture of all tissues in the
submitted pigs. Isolation of the causative agent from which organ would be significant
and most aid your definitive diagnosis? - ANSWERSBrain
Which of these postures suggests that the effective temperature is more likely too warm
for the pigs than too cold? - ANSWERSLateral recumbency with legs stretched out from
the body
A farmer is receiving pigs from a new supplier at the end of the nursery phase and
entering them into her finisher farm to raise for market. She has asked you to review the
performance data for the group from the 54 day nursery phase to see if you have any
concerns about health or growth. Which of the following is most likely to suggest that
there was a growth performance or health issue? - ANSWERSDaily average weight
gain = 0.5 lbs/day
The normal respiratory rate for a recently weaned pig weighing 12 pounds is: -
ANSWERS25-40 bpm
An established sow herd is experiencing severe shoulder lesions in sows that impact
sow movement, feed consumption and reproductive performance. Approximately 10%
of sows are affected and the lesions are usually bilateral. Your client asks for a
treatment strategy to fix the problem and lower the prevalence. What is the best
strategy? - ANSWERSCull the most severely affected sows, treat the remainder of
affected animals with topical antiseptics and increase feeding rate for the 10% of sows
with the lowest body condition scores
You are called to sow farm where piglets are developing creamy, pasty diarrhea within
48 hours of birth and it will last up to 5 days. The piglets display a rough hair coat and
