Metabolic Responses on Transport Stress and the Effect on Meat Characteristics (A Review)
ABSTRACT: Transportation plays
important role in animals and animal products business by distributing them
from producers to consumers or from farm to slaughter house. Unfortunately, the
transport from farm to slaughter house is a risky point for meat properties caused
by transport stress. Glycogen and glucose metabolism in stressed animal is more
fastened by epinephrine and
norepinephrine.
Glycogenolysis and glycolysis
process can be in aerobic
(TCA cycle) and anaerobic condition. If anaerobic condition
is dominant, it will produce lactic acid increasingly and cause PSE meat. If the animals
are able to
maintain the physiological
equilibrium by using
muscle glycogen up,
it causes glycogen deficiency and yields DFD meat. Both
are considered as poor quality. Consequently, the products made from these kinds
of meat have low properties and acceptability For avoiding both cases,
pre-slaughter handling is an important stage. The ways of it are adequate
resting time, giving electrolyte and sugar solution and so on.
