25
what are the two approaches to disease?
prevention (biosecurity) and treatment/control
26
what is the goal when approaching disease?
to prevent rather than treat
27
How can most diseases be avoided?
management, sanitation, and immunization programs
28
what are 5 disease prevention strategies?

29
What are the 6 causes of swine disease?
- bacterial - viral - parasitic - nutritional - genetic - toxins
30
what is an example of a bacterial disease in swine?

33
What is an example of a nutrition related disease in swine?
- Anemia (iron deficiency) - Rickets (Ca:P) - Para keratosis (low zinc) - Mulberry heart (low selenium)
34
What is an example of a toxin related disease in swine?
- Mycotoxins - Ionophore toxicity - Sodium ion toxicosis (water deprivation then rapid rehydration)
35
Why is the distinction of viral vs bacterial disease important?
They can cause similar symptoms
36
Why is it common to treat viral with antibiotics?
they kill the specific invading bacteria
37
What are the 4 evaluation levels when walking pens in a barn?
1.) building (site) 2.) barn 3.) pen 4.) animal
38
How are pigs assessed at the animal level?
Graded A, B, C, E which allows for effective communication of the status of a pigs health
39
what describes an A pig?
acute, treat and leave in the pen
40
What describes a B pig?
subacute, treat and either leave in pen or pull (company dependent)
41
What describes a C pig?
chronic illness, treat and pull to fallout pen and watch for signs of progress
42
What describes an E pig?
Humanely euthanize
43
when is the best time to treat a sick pig?
the earlier the treatment the better the response
44
what is bioexclusion?
keeping pathogens out of a population
45
what is biomanagment?
managing pathogens already in a population to minimize spread and negative outcome
46
what is bio-containment?
preventing pathogens from escaping from a populations
47
what is direct transmission of illness?
direct contact with an infected pig - gilts, weaned pigs
48
what is indirect transmission of illness?
indirectly through a contaminated object or other organism - equipment, feed, people
49
what is a pathogen carrying agent?
anything that can carry a pathogen from a source to a susceptible herd
50
what is an example of a pathogen-carrying agent?
- semen - truck - people - other animals - feed
51
What are the 3 failures of disease spread?
1.) Failure to prevent viral contamination/infection 2.) Failure to mitigate viral contamination or infection 3.) Failure to prevent transmission from virus agent to pigs
52
what is the most significant disease affecting swine in the US?
PRRS at nearly 1 billion lost
53
What are a few solutions to keeping a PRRS negative sow farm?
- advanced biosecurity - air filtration - feed mitigation - on-site disposal (composing)
54
What is PRRS?
Porcine reproductive and respiratory syndrome
55
what is sensible heat
conduction, convection, and radiation
56
what is latent heat
heat lost through the lungs by breathing or panting
57
how is latent heat lost?
evaporation of moisture
58
What impacts thermal comfort?
- metabolic rate - flooring - radiant temperature - air temperature - air speed - group size - relative humidity
59
how is air pulled into a barn?
exhaust fans create a slight vacuum
60
Definition of static pressure
different in pressure that creates a suction between the inside and outside, indoor air pressures lower than outdoors
