Abstract:
Poultry industry has been gaining prominence in the field o f Animal
Agriculture during the recent years; along with that there is a trend of
consumers to buy the best food at a least cost. Inspection is a major process,
which is commonly used by poultry manufacturing agencies as a promising
technique assuring the quality of broiler meat. Therefore this study was
conducted, to find out an effective sampling plan for post mortem inspection of
poultry. Random and systematic sampling methods were selected for testing,
while visual observations of characters were selected for the checklist. Visual
observations were done to observe on pathological defects, emaciation,
ammonia burns, bruising, breaking of wings and legs, inadequate bleeding,
dark coloured carcasses, fecal and bile contamination. Control charts were
drawn for wing tip bruises, breast bruising, bile contamination, fecal
contamination and wing bone breaking. There was no significant difference
(P>0.01) between the two sampling methods and however the systematic
sampling was considered as easier than random sampling. Inadequate bleeding
and ammonia burns were almost absent in bird carcasses on arrival at the plant.
The upper limit of average fraction defectives determined for wing tip bruises,
breast bruising, bile contamination, fecal contamination and wing bone
breaking were: 0.3185, 0.2837, 0.0746, 0.1356, and 0.1433 respectively. Fecal
contamination and leg bruising had over controlled points, so they should be
statistically controlled. Further studies are required for determination of upper
control limits for other important characters.
