Formulating Disease Prevention Protocols
factors to consider:
❏ Prevalent disease in the area
-confirm from reliable sources (e.g. PVO, BAI bulletins, OIE bulletins)
❏ Disease history of the farm
-trace the records of previous disease occurrences in the farm
❏ Current pathogen exposure of the animals
-have a monitoring program for diseases exposure (e.g. serological data, PCR data)
❏ Farm resources
- formulate what program is best fit to the farm based on its unique situation
example of farm reports
The program should encompass:
be ______in ur programs
recording of previous cycle, harvest recovery, survival rates, mortalities
holistic
the prgram should encompass 4 things (BAVB)
Biosecurity
- E.g. structure, farm practices, disinfection
❏ Animal nutrition
- E.g. Feed formulation, feed storage
❏ Vaccination/Medication program
- the programs should be applicable to the fram, based on needs
❏ Building management
-Hygiene, ventilation-temperature management, animal handling
before implementation of programs (DDCO)
Discuss the plan with the farm owner
-Keep an open channel, make sure both of you are in the same page
❏ Discuss the plan with the farm manager and farm hands
-Be ready to advice, convince, or push for the program
❏ Consider the resources available
-You might need additional equipment, facilities, or medications
❏ Oversee the preparations/implementation
- See to it that the agreed plans are applied
In an ____ system, a building
should at least have ___ week
downtime before loading
all
-in all
-out
1 week
alcohol is inhibitory in , the rest cidal
spores, mycobacterium (flammable, strong odor)
formaldehyde, glutaraldehdye, peroxides and acids, halogens is cidal in all (virus, bacteria, fungi, spores, mycobacterium) t/f
f - acids ay walang nakalagay kung cidal or inhibitory sa spores and myco. the rest cidal
HUman risk: formal irritating, explosive, carcinogen, allergen
perox: explosive, irritating
glutal: ellergen
halogens: chlorine and bromine iodine is cidal in alcohol in mycobac and cidal sa the rest t/f
t
human risk: irritating, reactive with other chemicals
phenols is cidal in spores, inhibitory sa iba t/f
f - inhibitory sa spores, cidal sa iba
human risk: toxic, absorbed through skin bioaccumulative
quartenry compounds is cidal in virus, cidal/lipophylic in bacteria, cidal in mycobacterium and inhibotiry in spres t/f
t - inhibitory in myco
acid is corrosisve t/f
t
in disinfection protocol –> use phenol 1st, 2nd and 3rd
glutaral 2nd, 3rd aldekol
- Phenol → after 24 hrs, airdy → glutaraldehyde → after 24 hrs, airdy→ aldekol → stay at least 7 days
: if no hx of disease challenge form previous cycle
single disinfection
if meron, 2nd then 3rd disinfection
routes of vacccination and medication (3)
❏ Feed medication
-oral route, medication is mixed
with the feed
❏ Water medication
-mixed with the drinking water
❏ Parenteral
-injections, topical application
dose of bacitracin for feed premix
ex. 500kg feeds; 2.5kg bacitracin x 0.5 ton
= 1.25kg
2.5kg/ton feed
brand: ZAMBAC MD 100 Zamira
use of overhead tank per building (e.g. 2000 Lts)
manual water medication
dose of vitamin supplment to finisher
80kg vitamin supplement requirement? or water requirement?
1ml / 1Lt water
15L/days
equipment for accurate dispensation of medications in drinking water
example of this
proportioner
dosatron
unit can handle a whole building with a large number of heads
proportioner
Routes other than through ingestion
