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.
The study carried out on various aged sheep between day to five
months which suffered from diagnostic clinical signs of white
muscle disease. Autopsy to all the sheep dead or slaughtered and
record all observations and histological biopsies of different organs
was collected.
The most outstanding features of gross inspection were wasting,
pale in visual mucous membrane, dyspnea, lung edema, and the
most parts of muscle were white.
In this study, ٢٦٥٠ slaughtered Awassi sheep and ٩٠٠ goats had been
searched for the presence of Hydatid-Cyst and Cysticercus tenuicollis.
As a result of this investigation, ٩,٦٩٪ of sheep and ٢٢٪ of goats were
found to be infested with the Hydati
d-Cyst, whereas ٢٤٪ of sheep and ٣٦٪ of
goats were found to be infested with the Cysticercus tenuicollis. The infestation
ratio was found to be higher in pasture animals older than one year.
The Hydatid-Cyst was found either in the Liver or in the lung and the
Extensity of infestation was more frequent in the liver than in the lung.
All kinds of Hydatid-Cyst such as the fertilized, sterilized, classified, or
caseinied were found in this investigation.
In this work, ١٥ digestive systems of Syrian Awass sheep, slaughtered in
Hama abattoir were examined, in addition faeces smaers, livers, lungs and
mesenteries were examined .
Very high infestation percent of Gastro-intestinal helminths was evident
.
Generally the intensity of infestation was of medium range, but it was very
high in the abomasum, then the small intestine and the large intestine in
decreasing order.
٢٣ species of Nematodes were identified, in addition to ٤ species of
Cestodes, Dicrocoelium dentriticum, ٢ larval-stage (Cysticercus tenuicollis and
Echinococcus cysticus-Hydatid cyst-), ٥ species of the first larvae of the lung
worms and ٩ species of Eimeria.
The most intense and wide spread was Marshallagia marshalli and
Ostertagia (Teladorsagia) circumcincta in the Abomasum, Trichostrongylus
vitrinus, Trichostrongylus capricola and Nematodirius filicollis in addition to
Moniezia expansa in the small intestine and Trichuris- sp. - specially Trich.
ovis and Trich. gazellae in the large intestine.
Gongylonema Pulchrum was found in Oesophagus. The results of this study
identified ٣ species of Nematoda for the first time in the digestive system of
sheep in the middle region of Syria. They are: strongiloides papillosus,
Chabertia ovina and Oesophagostomum venulosum.
This study aimed to provide an assessment of some anatomical
characteristics of the formal comparison to the kidneys of dogs
and sheep by studying of macroscopic anatomical differences and
morphometric measurement between the studied kidneys . (20
)
Kidneys were taken randomly during the slaughter of ten heads of
sheep in the local slaughterhouses, regardless of gender and age ,
Animals were clinically free of diseases and (20) kidneys were
taken from ten local stray dogs and regardless of gender and age ,
Animals were clinically free of diseases . the study showed the
presence of Morvomitrih differences in kidney (length – width -
thickness - weight) and some anatomical variations (renal pelvis -
renal Columns )between the kidneys of sheep and dogs. The study
pointed out there are many similarities between the kidneys of
sheep and dogs whereas revealed the length of the dogs kidneys.
