Chicken Meat production Flashcards
what steps need to happen for broiler management
- preparation for chick arrival
- brooding management
- growing out management - environment factors, rearing sexes, uniformity
- preparation for broiler marketing
- biosecurity and barn clean out
how do you prepare the barn for arrival
- litter is removed
- barn is cleaned (dry or wet) and disinfected, sprayed for bugs
- new litter
- equipment in place including supplemental feeders and drinkers (ensuring they are working properly)
- temperature is increase at least 2-3 days before delivery (everything needs to be warm)
- lighting set up needs to be set up before placement
what are RWA flocks
- raised without antibiotics
- they try to reuse litter to build immunity - natural immunity - but they arent aloud
what are advantaged to rearing sexes seperately
- management = specific diets/ compositions / amount
what are disadvantaged to rearing sexs seperately
- additional work and cost to sex the birds
how are chicks raised in canada
- typically raised together
- as hatched or straight run
why is uniformity important
- for the broiler industry
- for the producer
- for the processor - set all the equipment and determines where the cut is - to small may not get the right process of killing
- uniformity within flocks and between flocks
what factors effect broiler uniformity
- everything on farm = temp, diet, feeder space, ventilation, sex differences, culling
how do you prep broilers for slaughter
- remove feed 8-12 hours priors to slaughter = less contaminated (if inner meat touches GI stuff its contaminated)
- remove water when birds are caught - dont want then to get wet and cold
- raise all equipment to the ceiling
- dim lights or use blue lights for catching
what must you do for biosecurity
- all in all out - break disease cycle - clean out organic material and then wash and disinfect
- insecticide to control darkling beetles (vector for disease)
what is the primary method for disease spread
-transfer = use of contaminated equipment or exposure to contaminated clothing and footwear of humans
how does transfer happen
- bird transporting equipment, trucks, tractors, and other farm equipment as well as egg flats and cases = fomite
- humans - clothes, shoes, skin and hair = shower in and out at hatcheries
- animals - dogs cats mice rate and free flying birds
- insects - flies beetles and moquits
what should happen for prevention
- PPE - boots, gloves, masks coveralls
- limite visitors
- limit visitation to other poultry farms
- keep animals out of the barn
- rodent and pest control programs
-avoid contract with wild birds - location of the farm should be considered
- inspects barn daily - mortality and disease cases, cracks and barn opening s
- environmental control - appropriate little quality for example controls
- bird movement from barn to barn
what are the barn designated control zones
CAZ - controlled access zone = outer area which include entire area where poultry are kept and handled
RAZ - restricted access zone = located inside the CAZ to which access is more tightly controlled
CAP - controlled access point - each access point to the CAZ or RAZ referred to as controlled access point and are entrances used by all traffic
what are zone requirements
- biosecurity sign at each CAP to instruct unauthorized people not to enter
- visibly defined barriers with clear instructions to be followed at CAZ or RAZ
- doors locked at all timed, including around the entire CAZ
- training on biosecurity protocols
- handwashing, boot supplies before entering RAZ
- shower in and out if possible
