10. Manual system- utilizes gravity or manual
pushing/pulling and lifting
Semi-mechanized system- utilizes a mechanized system
on selected slaughtering processes.
Fully-mechanized system- utilizes fully automated
equipment for elevating and lowering of animal and
carcass. The overhead railing system for this classification
is continuous at a constant speed.

13. It should have complete facilities for prior care of animals prior to
slaughter
Should have good ventilation
It should have separate dressing floors for hogs and large animals
Separate room for handling meat and offals
There should have an equipment and implement for proper handling of
meat and byproducts
There must be provisions for hanging carcasses and if possible
refrigeration facilities
14. Adequate water supply and if possible pressurized,
water supply should be potable. Water heater should
be provided to facilitate cleaning of facilities and to
minimize use of detergents
Requirements for water: Cattle - 60 gallons/heads Hogs
- 30 gals/head Goat/sheep - 15 gals/head Poultry – 7
gals/head
With waste disposal facility

18. Recommended Extraction Rate
Refers to the proportion of animals in a given population that can be slaughtered for
one year. The following are recommended percentage per species.
Carabao 11.15%
Cattle 22%
Hogs 135%
Goat 85%
Chicken 397%
Ducks 65%
19. 1
Reasons for the differences in the Recommended Extraction Rate
1. Species differ in production/growing period
- carabao/cattle – 2-3 yrs slaughter wt
- hogs - 2 batches/yr
- chicken - 38-40 days/batch
2. Species differ in reproduction rate
- carabao/cattle - 1 calf/birth
- hogs - 10 piglets/litter
20. Reasons for the differences in Extraction Rate
3. Species differ in reproduction cycle/ gestation period
- carabao - 324 days
- cattle - 283 days
- hogs - 114 days

21. depends mainly on the purpose the meat is to be used
and on the cost of the end-product
the meat produced should possess the characteristics
necessary for the products or recipes to be made
ex. for comminuted products manufacture then it should
have high water holding capacity, high emulsion capacity
22. 1. Sex Type
◦Fresh meat retailing – gilt, barrow, heifer & steers are
recommended
◦For processing – stag, sow, bull, cow
- Boars are not used for processing and fresh meat retailing
due to the boar taint odor – the 5-α-androst-16ene-3one,
◦For processed meat:
a. Intact meat (ham, bacon) – gilt & barrow
b. Comminuted – sausage, hamburger – stag, sow, cow (Has
high WHC, flavorful)
23. 2. Age
the older the animals the darker the meat and is less
tender (tougher) but is more flavorful compared to young
ones
• hogs – 6-12 months before, now 4-5 months weighing
about 90 kg
• cattle/carabao – 2.5 to 3 years
• native cattle - 3 to 5 years; crossbreds- 3 years
24. 3. Condition and Health of the Animal
-should have an optimum condition, not too thin, not too fat
-Only healthy animals are recommended for slaughter
-Slaughtered animals are intended for human consumption
26. 5. Loin Eye area and other measurements considerations
◦wide loin eye area in swine is indicative of high lean cut and
low fat cut yields
- hogs with wide loin eye area are ideal for slaughtering
29. 6. Degree of fatness consideration
◦in meat, palatability factors like flavor, tenderness and
juiciness are influenced by fat
◦30 to 40% fat is the most acceptable for comminuted beef
and pork products
◦at this fat level meat tends to lose much weight during
cooking but remains juicy, tender and flavorful
--thicker backfat= higher dressing percentage but yield lower
percent ham, loin and lean cuts
30. 1. Fasting – the withdrawal of feeds and giving an ad
libitum amount of water
-Ruminants – 48 hrs (24-48 hrs)
-Hogs – 12 to 24 hours
-Poultry – 6 to 12 hours
HANDLING OF ANIMALS FOR SLAUGHTER
31. Why fast?
to save feeds
make cleaning of entrails easy
makes cleaning and evisceration easy
thorough bleeding (longer shelf life and bright colored
carcass)
saving in water consumption and reduced water waste
HANDLING OF ANIMALS FOR SLAUGHTER
32. 2. Let animals relax and avoid any form of stress prior to
slaughter
◦For mild stress (usually stress condition) – let the animals
relax for 12 – 24 hours
◦Severe stressful condition – rest for 24 hours with sufficient
feed and water, fasting will follow for another days
33. Disadvantages of stress:
a. loss of muscle glycogen (the reserve energy) and meat pH
b. Affects the water holding capacity
c. Loss of flavor, color, juiciness, tenderness
in a carcass, glycogen is converted into lactic acid that controls the pH
of the meat (ideal pH-5.7 to 6.0)
more glycogen present in the muscle, the greater the potential for
lower ultimate pH.
High pH =DFD (Dark, Firm and Dry) meat---Long term stress
Low pH= PSE (Pale, Soft, Exudative) meat--- short term stress
34. 3. Handle the animal gently or with care
prior to slaughter
- avoid mishandling the animal, like: kicking or boxing – causes
blood clots,
- provided in the RA 8485 “ Animal Welfare Act”
4. Cleaning the exterior of the animal
- before slaughtering to avoid contamination
- the hide is a potent source of contaminants
35. 1. Cleanliness of the carcass
- proper hygiene to produce clean
carcass
2. Hygiene of production
- Good Manufacturing Practice (GMP)
-Hazard Analysis Critical Control
Points (HACCP))
FACTORS TO CONSIDER IN SLAUGHTERING
ANIMALS
36. 3. Efficiency of meat inspection
- to avoid spread of disease to humans
4. Adequacy of meat preservation
- availability of chiller/ refrigeration
facilities
- allow to drip for 30 minutes before
transfer to chiller
