تم دراسة التركيب الكيميائي لحليب الأم و مقارنته مع حليب الأبقار في محافظة حمص - إن قيمة المادة الصلبة الكلية في حليب الأبقار (12.26 ± 1.2%) مساوية تقريبا لمحتوى حليب الأم من المادة الصلبة الكلية (12.11 ± 0.09%). - بلغ محتوى حليب الام من العناصر المعدنية (02% ±001%)في حين أن محتوى الأبقار(0.71 ± 0.14%) - بالنسبة لقيمة المادة الدسمة في حليب الأم (3.5 ± 0.02%)تتساوى تقريبا مع محتوى حليب الأبقار من المادة الدسمة(3.4 ± 0.05%). - محتوى حليب الأبقار من المادة البروتينية يعادل(2.92 ± 0.019%) في حين محتوى حليب الأم يعادل( 1.25 ± 0.009%) إن قيمة الكالسيوم في حليب الأم (32 ± 4.3 mg)أقل بكثير من قيمة الكالسيوم في حليب الأبقار(118 ± 8.2 Mg/ kg).
A study of chemical composition of woman's milk has been made and compared with cow's milk in the province of Homs. The findings of this study show that The total value of the solid material in cow's milk is (12.26 ± 1.2%). It is approximately equal to woman 's milk content of the total solid material which is (12.11 ± 0.09%). The woman 's milk content of mineral elements is (02% ± 001%), while the cow's milk content is (0.71 ± 0.14%). For the value of fatty material in the mother's milk, it is (3.5 ± 0.02%) and this is almost equal to cow's milk content of the same material which is (3.4 ± 0.05%). The cow's milk content of protein is equivalent to (2.92 ± 0.019%), whereas cow's milk content is equivalent to ( 1.25 ± 0.009%). The value of calcium in the mother's milk is (32 ± 4.3 mg), and this is significantly lower than the value of the calcium in cow's milk, which is (118 ± 8.2 Mg/ kg).

In this paper, we evaluated some varieties of local white cheeses (Baladi and
Akkawi). 100 samples were collected randomly from various production sites in
Syria between 2003 and 2004. Chemical and microbiological analyses were
applied to determin
e their suitability to the Syrian standards. This study shows
that their quality do not fulfill the set minimum Syrian quality standards. The
microbiological analyses (Coliform, Escherichia, Staphylococcus aureus, and
Salmonella), rate was 75% for Coliform organisms and 66% for Escherichia in
Baladi, while it decreased to 43% for Coliform and 25% for Escherichia in
Akkawi. As concerns the positive coagulation bacteria (S. aureus), the rate
exceeded 15% for both types of cheeses. 18% and 12% of Salmonella were
found in Baladi and Akkawi also respectively. Various types of Coliform and
Salmonella were identified. This study indicated that local cheeses have no
uniform or standardized chemical characteristics. The averages of acidity,
moisture content and salt percentage were 0.24%, 60%, and 2.6%, for Baladi
and 0.28%, 53.53%, and 9.96% for Akkawi, respectively. The fat content had a
wide range for all cheese samples. This study classified these fresh cheeses as
raw cheeses that have vast flora and no uniform chemical and quality
characteristics. The above findings, lead to different defects and properties
which do not fulfill the Syrian quality standards. Thus, the quality of Syrian
cheeses varieties is still questionable.
the residual lead effect in cows milk was
studied in the Governant of Tartous. For this end,135 dairy cows in
different milking seasons and from three different farm stationes
(Zahed cow station,Cement factory farm station and Banias refinery
cow
station) were used.
The objective of the study was to accurately determine lead
concectrations in cows milk in the three different farms. Samples of
milk,soil,water and feedstuff were collected and lead concentration
was determined then statistically analyzed.
The aim of this research is to study the most important physical, chemical and
microbial changes in several kinds of infant milk available in local markets. The milk
samples were studied in conditions similar to those used by mothers when they prep
are
infant milk bottles at their houses. The results showed that moisture content increased in all
samples from approximately 1% to 3.2-4.4% after storage for 9 days. Acidity increased
considerably from 0.14% to 0.2%.
The results showed that peroxide value passed the allowable limits (0.25) and
reached about (0.47) in samples stored for 9 days at room temperature. However, the value
for samples stored in the refrigerator ranged between (0.25-0.29). The free acidity number
of fat for all samples specially the refrigerated ones was within the natural limits (<0.5).
Chromatographic analyses showed apparent differences in fatty acid percentages between
the kinds of milk. The rate of lenoleic acid (C 18-2 ) decreased during storage in all samples
and in all conditions.
Soluble nitrogen increased in all samples at the end of storage and the highest value
was 0.49% in Nido milk samples. The solubility of milk samples was checked during
storage and was found to decrease very little ( 1%).
The total count of aerobic bacteria showed that all samples conform to the Syrian
standards (No. 197, 1996) during the first six days of storage, but they passed the upper
limits at the end of storage. However, all samples were free of pathogenic microbes .
The research was carried out in the center of the Research and
Improvement of Sheep and Camels in salamiah. The study was
conducted on 9 female camels, within semi-open barns, semiintensive
care system, and the camels were fed on mixtures of
barl
ey, vetch and some concentrated fodder, Fodder mixtures were
determined to suit the nutritional needs of the physiological and
age-related condition of the study. The herd was also applied to the
preventive vaccination system according to the preventive immunity
program.
Food safety and monitor of the contents of agricultural products are matters of great
importance for consumers, as a result of food awareness, public health and disease
prevention.
The aim of this study is to know the concentrations of some heavy
metals (lead -
cadmium - nickel - chromium), in some fodder plants (Trifolium ssp., Cynodon dactylon.,
Avena sativa L.), and the extent of its secreted in the milk of cows in the area of Banias on
the Syrian coast.
