Conditions for Gas chromatography (GC) equipped with Flame Ionization Detector (FID) were optimized in order to dtermine volatile N-nitrosamine in meat and meat products, using optima XLB (30m × 0.25 mm × 0.25µm) column. Results reveal that the metho
d has a low detection limit with repeatability and linearity and with average recovery ranging from 89% to 105.5% and accepted relative standard deviation
The aim of the present study was to determine the levels of lead and cadmium in the
meat, liver and kidney of sheep exposed in the local markets of the city of Latakia, and to
compare the results with those reported by other countries and with the
maximum
acceptable levels for human consumption, Lead and cadmium were determined by atomic
absorption spectrometry (AAS).
The mean concentrations of lead in meat, liver and kidney were 0.043, 0.284 and
0.118 mg/kg fresh weights, respectively, while mean concentrations of cadmium were
0.017, 0.173 and 0.252 mg/kg fresh weights, respectively. Statistical analysis showed a
significant difference in lead and cadmium concentrations between liver and kidney and in
meat.
This study was conducted to use regression equations as indirect methods to
estimate amounts of meat and fat in broiler carcasses of Arbor-Akroz hybrid.
Sixty broiler birds (٣٠ male and ٣٠ female) aged ٤٩ days and reared at a
private farm were use
d . The length of (truck, neck sternum, head, tibia.
lemur, libula, rumb), the width of (head, intervel between iliums, chest,
abdomen), circumference of (thigh, tibia) the high of head and chest and depth
of chest were measured before slaughtering. Birds were slaughtered, cooled for
٢٤ haurs, weighted before and after cooling and the above measure merits
were repeated after slaughtering. Carcasses were dissected and weights of
muscles in the chest, thigh and hypo thigh, amount of fat in the abdominal
cavity and weight of heart and the head were recorded .
This study was conducted at the farm of the Faculty of Agriculture
(Damascus Univ.), using twenty local rabbits.
These rabbits were housed, managed and fed under the same conditions.
They were identified and distributed into two groups according to the weaning
times (٢٨ vs ٤٢ days).
It was concluded that weaning time has no significant effect on meat
proportion in local rabbits.
