Midterm Flashcards
mental health
state of well-being where an indiv realizes own capabilities, can cope with w/ normal stressors, work productively, & contribute to commun
animal health
absence of disease
normal physiological functioning
normal behavior
productivity (prod an)
healthy living envir
good welfare
3 circles of an welfare
physical ⟶ health & functioning
mental ⟶ affective states
natural state ⟶ nat behav
5 domains of an welfare
- nutrition ⟶ water & food access & quality
- envir ⟶ temp, confinement, shelter
- health ⟶ disease, injury
- behav ⟶ choices/limitations
all above affect
# 5. mental state: pain, thermal comfort, boredom, frustration, happiness
disease
disorder of structure or function, esp one prod specific sympt/affects specific location
- includes physc injury
envir health management
external factors impacting an health/welfare
- preventative
- human controlled
- human decisions
areas of envir health management
- general husbandry
- biosecurity
- nutrition
- housing, ventilation, & shade
- behavior needs
general husbandry practices for best envir health management
ways prod/facility staff can ↓risk of dis for indiv/group
a) avoid/minimize mixing social groups
b) ↓ stocking density
c) good access to reliable food/water
d) climate/weather control
- ex: phys changes from heat stress ↓ immune
e) preventative & reg vet exams/tx
f) waste removal
g) handling/procedures
- well-trained handlers able to identify disease sympt/behav
- poor handling ⟶ stress ⟶ phys changes
⟶ ex: pinning cats for BG test
⟶ ex: lab animals ⟶ phys changes skew data
biosecurity practices for best envir health management
protocols to prevent/minimize intro/spread pathogens
1. people:
- PPE
- facility clothes/scrubs/boots
- footbath
- showers in/out
- disinfect new equipment
2. fomites: frequently sanitize all surfaces/equipment (new & old)
3. animals:
- new ⟶ isolation & vet exam
- vx
- routine exams & dx testing
4. contaminated feed/water:
- know source
- closed/safe storage
- reg path testing
5. envir exposure:
- ecosystems an exposed to
- types of chem/phys/bio ways required of envir
- managing wildlife
nutrition practices for best envir health management
key to ensuring health/prod
- good nutr can improv health, ↓ risk dis, improv immune,
- poor nut = poor phsy cond, immune, GI, ↓ prod, welfare
housing, ventilation, & shade practices for best envir health management
- animals confined indoors need:
- reliable source of ↑quality food/water
- good waste management ⟶ breeding ground for dis/vectors
- adequate vent/humid control:
- ex: chx: >80% hum ⟶ excess
moisture ⟶ wet litter ⟶ skin
infx/lesions = foot pad
dermatitis
- ex: chx: >80% hum ⟶ excess
soln: ↓ stocking density, improve vent/hum control, litter material, ↓water = ↓ urine
- animals liv outdoors/outdoor access:
- ↑ risk accidents, predation, dis, death
- protection from envir/ elements necessary ⟶ partial/full shelter
- ex: heat stress in cattle
- adequate access to food/water
behavioral needs practices for best envir health management
behavior changes/stereotypies indicative of poor health/welfare
- behav manifestations
- important for identifying
- ex: parasitic eye fluke & rainbow trout
solution:
- add behavioral assessment to clinical exams
- limit handler influence
- assess animal under natural housing conditions: O vid of natural vs concerning behaviors
housing influences on health
species & indiv-specific housing necessary ⟶ chronic stress & ↓ immune fx ⟶ ↑ risk of dis
ways of improving envir
envir enrichment provides captive anim an opportunity to perform highly motivated species-specific behaviors
- supervised testing necessary
- ex: FB
genome to phenome
genetic-phenotypic connection
humans select traits for:
a) food: ↑ prod an mass/output helps global food security
b) ag sustainability: ↓ land/water use, ↓ GG
c)↑ fitness ⟶ more resilient to CC, dis, pests
d) consumer/O needs
- lean/healthier meats
- pet breeds
AMR
antimicrobial resistance: one of biggests threat to global health
pathogens mutate & no longer respond to meds ⟶ infx hard to treat ⟶ ↑ risk dis spread, severe I’llness, death
antimicrobial
antibiotic
med inhibits growth/destroys microbe
antimicrobial for bacteria
major uses of animal abx
- growth promotion:
- indoor intensive livestock facilities
⟶ ex: pigs & poultry
- low sub-therapeutic dose
- in feed/water
- thought to decrease GI bac ⟶ more food = more energy to grow - prophylactic
- reg therapudic dose
- preop: injury ⟶ 2h prior to op
- periop: 2h prior surg ⟶ completion (best)
- postop: completion ⟶ recovery
- all species: companion, lab, livestock, aquaculture - treatment for clinically diagnosed
- clinical signs: observable symptoms
- DVM dx
- control infx & ↓spread
economic goal of food prod
large farms w/ max livestock best for feeding huge pop w/ minimal effort & cost
food prod styles
intensive
- ↑ farms/barns
- ↑crowding = ↓space
- no outdoor access = ↑ risk & spread
semi-intensive
- smaller farms/barns
- ↓ crowding = ↑ space
- some outdoor access
6 degrees of one health
all living org are ≤6 steps from eachother
systems approach
non-traditional proactive approach to complex world health issues
- no boundaries
- often uncertainty
- transdisciplinary
1) focus: understand dis/health = comlpex
2) cause: complex interactions; mult factors
3) treatment: multifactoral, multimodal
4) approach: holistic, broad
challenges to a systems approach
- diff to solve specific problems alone
- costly & time-consuming
- relies on new treatments/philosophies
traditional approach to health
biomedical
1) focus: physical aspects of illness
2) cause: external factors ⟶ disease beyond indiv control
3) treatment: healthcare providers ⟶ diagnostics ⟶ meds & surgery
4) approach:
- reductionist
- examine indiv parts, not whole
- mechanistic
- inflexible
- body ⟶ organs ⟶ cells
