Q
what is health surveillance?
A
set of planned measures in a hunting ground
2
Q
what are the goals of health surveillance?
A
- recognise the risk of a disease, its occurrence and possibility to spread over
3
Q
what are the basic components of health surveillance
A
coprological exams
PM exams
quarantine measures
4
Q
what is the most common cause for morbidity and mortality of game species?
A
parasitic disease
5
Q
what should partial necropsy follow?
A
sanitary and harvesting culling
6
Q
two type of measures in health surveillance
A
preventive:
- understand the situation which needs implementing of preventative measures at the high risk area
corrective:
- implementation of targeted therapy
- speeding up transportation of game
- reducing time required to implement quarantine measures
- reliable relocation of game
7
Q
methods of implementation of health surveillance
A
- collecting data about game (species and number)
- collecting about hunting ground
- abundance of certain game species
- collect about epizootiological situation
- collect specimens of faeces
- implement quarantine measures
- collect samples for diagnostic test
- assessment of stress levels
- necropsy of carcass
- inspection of slaughterhouse
8
Q
coprological monitoring
A
- carried out in 2 ways: either joint sample or individual sample
- collection at selected locations
- faeces are collected at game gathering places
- should be fresh. required number is relative to size/number of population
- should represent at least 40% of population
- collected in special plastic containers
- individual sample should be taken twice a year (spring and autumn)
9
Q
stress level assessment
A
- major problem with stress, is decreasing immune system and making them susceptible to disease
- done by taking faeces and testing level of cortisol metabolite in faeces
- frozen straight away to prevent further degradation
- immunoenzymatic assay
10
Q
necropsy
A
- carry out as many as possible
- dead game is rarely found that is suitable so often based on sanitary and harvesting culling
- prior to necropsy check for either anthrax or rabies
- field necropsy - only be county vet
- wear protective clothing and researcher should have rabies vaccine
11
Q
advantages of health surveillance
A
- know the cause of the mortality of morbidity
- prevent critical moments
- safer procedure for handling and transportation
- cheapest prophylaxis
- improving health and quality of game population
12
Q
field work - health surveillance
A
- it’s necessary to visit the hunting ground
- need map of ground with drawn positions
- all objects should be marked with numbers
- introduce the members of the society and explain:
> the purpose of it
> what’s the reasonable time window
> who need to do what
> individual and total cost and method of reporting - need to do final report with opinion and advice
13
Q
sample collection and delivery
A
- maximum caution is required during sampling
- when rabies suspected:
> small - whole corpse sent
> large - only head, in airtight containers - blood samples be taken in pre-prepared tubes
- samples accompanied by a cover letter
- samples sent by courier, hygiene service deliver or in person
14
Q
hygiene and sanitary measures
A
set of measures with a preventive purpose in order to protect wildlife/domestic animals/humans
- partial sanitary culling
- reducing culling of overabundant predaotrs
- removal of stray dogs and cats
- harmless carcass removal
- reclamation measures
- disinfection, disinsection and pest control
15
Q
sanitary culling
A
- measure by which game animals with visible signs of disease are excluded from further breeding
- measure is justified only in case if no medical treatment is possible/ not achieve healing
- 2 levels of implementation: single (non expert) or total (vet authorities)
- advantages of sanitary culling is it completely eliminates sick animals and helps to find the cause
- disadvantage, is changes in behaviour doesn’t mean sanitary culling is needed
- single sanitary culling if curing isn’t possible
- total = cannot be avoided in case of severe or highly contagious disease
- hunt rights holder is obliged to report each culling with certificate and proof of disease
16
Q
first detection of the disease
A
- easiest and most unreliable is observation and visual assessment but it’s the first step in game animals
- observed from observation points at high seats
- look for thinness, blood, deformities, bad hair coat, etc
- sudden death of large number = infectious disease or poisoning
- reduce the overabundant predator
- remove stray dogs and cats
17
Q
harmless carcass removal
A
- to prevent the spread of pathogens
- collect carcass and eliminated the infection or to determine the cause of death
- shipped to incineration plants or necropsy
18
Q
burying
A
- simplest way to bury is make it deep enough that animals cannot reach
- should be poured with lime for disinfection purposes
- surface of soil that animal was lying on, also buried
- drained terrain
- pour on with non-slaked/quick lime
- minimum of surface soil layer is 0.5m
- small game at finding site
19
Q
burning
A
- depending on season and potential risk of forest fire
- dig a shallow pit
- fold the combustible material
- put on the corpse
- wait until combustion is completed
- bury the pit
20
Q
disinfection, disinfection and pest control (DDPC)
A
- for fenced game breeding, it’s important
- PC for forest company to protect oak saplings
- PC by agricultural company to protect crops
- at management facilities
- PC doesn’t eliminate all rodents
- advisable to undergo microbiological and serological monitoring twice a year
- game management practice use fenced hunting grounds….

38
reproduction of brown hare
special attention of: exterior, health, body condition, temperament and productive properties of ancestors
if breeding pair is acquired from other farm/directly from nature quarantine of 30 days is requires
female fertile at 4-6 months of age
pairs are in reproductive function 3-4 years, but best is 2nd and 3rd
sex determination
mating of hares in cages starts naturally in second 1/2 of jan
1st litter = march/late feb, last in sep, then reproductive rest
average 5-7 litters per year
- young hares spend 23 days with their parents
- after 1st 2 weeks, start solid food intake
- after 23 days, removed and houses in cages for young hares
- 70 days, moved into the polygon for adaptation
39
adaptation of brown hare
- performed at farm location or in hunting area
- terrain of polygon must be dry, with quality grass cover and covered by protective net
- inside: feeding and fresh water
- natural instincts last minimum 7-10days (self preservation) after that, they're caught and transported
daily monitoring is required due to entry of predators
40
capture and transport of brown hare
- after netting capture, they're placed in transport boxes, which should provide: enough space, sense of safety and good ventilation
- bottom of box mustn't be slippery

51
factors that influence dosage calculation
specific dose - according to game species - mg of active sybstance/1kg bw
individual dose = specific dose x kg
condition, body weight, older animal needs less dosage, environmental conditions
52
approach and post capture maangement
after induction period carefully approach to animal
physical restrain is recommended
put blindfold on eyes
remove tongue tip out of mouth cavity
measure body temp
use portable pulse capnograph
53
medical emergencies from chemical immobilisation

- bloat and regurgitation - darting at feeding/drinking point, main risk is aspiration pneumonia
- vomiting - occurs at end of induction period but im ruminants usually at beginning stage
- cardiac arrest - overdosing of active component, immediately administer antagonist
- hyper/hypothermia
prevent all these by using sternal position
54
drug selection
1. neuromuscular blocking drugs
2. central acting drugs (mostly opioids, cyclohexmine, alpha 2 agonist)
55
commonly used drugs for immobilisation
ketamine hydrochloride

what is wildlife management?
attempts to balance the needs of wildlife with the needs of people using the best available science
includes: game keeping, wildlife conservation and pest control
90
is game breeding?
game keeping is the management or control of wildlife for the wet being of game and may include killing other animals which share the same niche or predators to maintain a high population of more profitable
91
manipulative maangement
acts on a population, either changing its numbers by direct means or influencing numbers by indirect means (altering food supply etc)
92
custodial/conservation management
preventive or protective
aim is to minimise external influences
93

limited entry
- where number of animals taken is to be tight controlled
closed season:
- wildlife is protected from hunting and is enforced by law
94
killing vs culling
to kill is to kill
to cull is to pick or take someone or something from a larger group
culling is a strong selection force and can therefor impact the population genetics of a species. process of removing or segregating animals from a breeding stock based on specific trait
