pre-slaughter handling
cattle: dark, firm & dry (DFD)
pigs: pale, soft & exudative (PSE)
stress > can cause hormonal changes > lower-quality & tougher meat
weight loss > dehydration & reduced muscle mass > impacts meat texture & yield
health issues > may develop or worsen due to pathogens, poor ventilation or temp. flunctiations
unloading: resting animals in pens (resting period)
accidents or injuries > sections of meat being discarted
improves meat quality
transport: moving animals from farm to processing facility
restores energy reserves

transport vehicle design
protection from weather
space for standing naturally > to reduce discomfort & stress
non-slip flooring with bedding > to prevent falling + to absorb waste
ventilation > to prevent heat stress + to reduce buildup of exhaust gasses
cleanliness & sanitation > to prevent illnesses
impact on meat quality
depletes glycogen (muscle's energy store) > affects pH + can lead to quality issues > impacts appearance, tenderness & water-holding capacity (WHC)
lower shelf life
high stress
stress hormones > increase susceptibility to spoilage bacteria
slaugther technology
stunning
minimize negative effects on quality
keeps animal unconsious until death
