Abstract

The research which was conducted in the laboratories of Syrian Arab Standardization and Metrology Organization (SASMO) aimed to estimate the daily intake of lead (Pb) and cadmium (Cd) for adult person of 70 Kg weight when he consumed 100 g/day of canned chicken luncheon meat of 5 different brands samples, three of them were locally processed (A, B, and C), while two of them were imported (D, and E), and all brands were sold in the markets. The results revealed that lead levels of the samples differed significantly and ranged between 0.351 and 0.73 mg/Kg (p≤0.05). The samples A and E exceeded the permissible limit which is mentioned in the Syrian Standardization and Metrology number (2719) (>0.5 mg/Kg) in 2008. Regarding cadmium levels, it ranged between 9.37 and 15.22 µg/Kg, and all samples were within the permissible limit according to FAO, (1980) (>100 µg/Kg), and according to ECR, (2006) (>50 µg/Kg).  The daily intake (DI) from elements was compared with acceptable daily intake (ADI), which is recommended by Syrian Standardization and Metrology number (575) in 2009 (250 µg/day/person of lead and 70 µg/day/person of cadmium). The results exhibited that the daily intake of lead ranged between 35.1 and 73 µg/day/person, with a contribution percentage ranged between 14.04 and 29.2% of the daily intake, on the other hand cadmium daily intake ranged between 0.937 and 1.522 µg/day/person with a contribution percentage ranged between 1.33 and 2.17% of the daily intake. We conclude that the consumed canned chicken luncheon meat of different studied brands constitutes an important source for lead and cadmium, with the possibility of exceeding the permissible limits for some brands.

Key words: Cadmium, Lead, Accepted daily intake, Chicken luncheon meat.

Abstract

This research aimed to identify the proportion of female breeders of cows, who make dairy products, and study the effect of socio- economic variables affecting the women’s decision in making these products, and to determine the value-added, which is caused by the female breeders that due to the dairy products process, in Sweida, Syria. A stratified sample sized of 192 cow breeders was selected, based on a field questionnaire during 2014. The results showed that 82.3 % of cows’ breeders make one product at least of dairy products. The results also showed that 100% of them make yoghurt and labna, 98.7% make cheese, 72.2 % make ghee, 66.5 % make kishk, and 46.8 % make Aelchencklish. The results, also clarified significant negative relations between the dependent variable, which was a dummy variable represented by the women’s decision of making dairy products, and each of the independent variables involving, the educational level of a woman, having another job outside the house, price of milk. While there was a positive relations with each of the independent variables including, the families’ size, and economic awareness. Results also showed that the value-added, which is caused by women from making 1 kg of milk, is accounted to 10sp for yoghurt, 17.4sp of labna, 8sp for cheese, 9.2sp for ghee, 10.3sp Aelchencklish , and 81.4sp of the kishk, which achieved the highest profit as a result of making of milk.

Abstract

The study was conducted at the Shatha Buffalo Research Station in Hama/Syria during 2011, to determine the effect of some factors affecting birth weight, weaning, and growth rate of born buffalo such as the father, season of birth and month of birth, sex and year of study.
The available station records were used for this purpose from 1997 up to 2008. The results showed a significant effect (p ≤ 0.01) for each of the year, season of birth, the father, and month of birth on birth weight, it was noticed that males were heavier than females at birth with a significant effect (p≤ 0.05), and weaning weight of 90 days influenced significantly (p≤ 0.01) by the year and month of birth, also the effects of father and sex were significant (p≤ 0.05), but no effect in terms of the number of the season. Considering the growth rate during breastfeeding period the impacts of year, father, and month of birth were significant (p≤ 0.01), also and the impact of sex was significant (p≤0.05), but no effect of the season number. The genetic heritability was estimated by the variance components of the parents, which was for birth weight 0.360 ± 0.03, and was for weaning weight 0.406 ± 0.06, while it was for growth rate 0.390 ± 0.02, this shows that there are several factors affect birth weight, and weaning, and growth rate in the Syrian calves buffalo during breastfeeding, therefore it is necessary to focus on improving the environment where the animal is besides the genetic improvement in breeding programs to get the required genetic gain.

Keywords: Buffalo, Birth weight, Weaning weight, Rate of daily growth, Heritability.

Abstract

This study was carried out at sheep section – Shami Camels Research Station, Damascus country side. Twenty-four lactating Awassi ewes homogenous in terms of age (5 years) and production season (fourth) and milk yield in the previous season. The ewes were divided randomly into three groups. All housing and management conditions were similar for all sheep throughout experiment period (105 day post-weaning). The first group T (control) was fed on basic ration (concentrate feed, barley-vetch hay, fresh forage), while the second T1 and the third T2 groups were fed on basic ration supplemented by yeast (3 and 5 g/head/day, respectively). The results showed that the average total gain was higher in T2 (P≤0.05) as compared with control (6.25 vs. 4.89). Milk yield amounted 65.82±2.47, 71.57±3.86, and 70.27±7.81 kg for T, T1 and T2, respectively. T1 milk yield was higher (P≤0.05) by 8.7% than that of T. There was no significant differences between the three groups for milk components (fat, protein, lactose and total solids), while amount of total fat was significantly (P≤0.05) more than 16.1 and 13.7%, respectively for T1 and T2. It can be concluded that the addition of live yeast Saccharomyces cerevisiae at a rate of 3 g/head/day to the diets of dairy ewes gives the highest milk production vs 5 g/head/day for better gain in body weight.

Keywords: Awassi sheep, Yeast culture, Milk yield, Fat.

Abstract

This research was carried out aiming to survey diseases of Mountain and Hybrid goats (1/2Mountain, 1/2Shami) and to assess disease infections and their rates at Aura Goats Research Station in Al-Sweida, General Commission for Scientific Agricultural Research (GSAR), Syria, during 2006-2011. The most important repeated infections at the station were recorded by using phytosanitary records, and observing goats closely, in addition of making serum laboratory exams for Toxoplasm gondii by using Toxo –Hat Fumouze test, and Chlamydia Psittaci by using  (ELISA) test. These infections were classified according to their positions in the animal’s body systems. Results showed that Mountain and Hybrid goats at the station were infected with several diseases, where the infection rates varied from race to race. The infections with alimentary and respiratory systems diseases were higher, where infection rates with alimentary system diseases at Mountain and Hybrid goats were (46.36,  33.36)% respectively, whereas infection rates with respiratory system diseases were (21.51, 24.31)% respectively. Mastitis, nervous system diseases, metabolic diseases, urinary system diseases, skin diseases, abscesses, foot infectious, eyes diseases, general weakness and frailness had related rates in Mountain and Hybrid goats, but Enterotoxaemia spread in Mountain goats only. The statistical analysis showed that there is no significant difference in most diseases between Mountain and Hybrid goats except alimentary system, metabolic, urinary system diseases (p<0.05). Serological tests showed infection prevalence with Toxoplasma  gondii, Chlamydia Psittaci in both races, but with different rates, where the serum spread rates of Toxoplasm gondii were 13.04%, 16.66% in Mountain and Hybrid goats respectively, whereas the spread rate of Chlamydia Psittaci was 4.16% in Hybrid goats, without any infection in Mountain goats. Chi square test showed insignificant difference of diseases rates between Mountain and Hybrid goats for both diseases, where chi square value was (1.148) (P≥0.05).

Key words: Disease infections, Mountain goats, Hybrid goats.

Abstract

This research was carried outduring the period 2009-2012to identify locations of wild olive (Oleasylvestris) distribution in Hama governorate in Syria. The most important three locations of wild olive were chosen i.e. Sigata, Tal Aafar, and Ain Al Nabed. 20 morphotypes were selected and characterized from the three main regions, depending on IOC application; also the fruits were characterized depending on the oil content. The results indicated wide diversity within wild olive genotypes at the same location and between all locations. Wild olive is a collection of genotypes rather than ecotypes. Genotypes wa6, wt8, and ws2 were selected as double purpose (oil and pickling), wa4 and wt4 for oil, while wt6 was selected as pickling genotype. The results exhibited the efficiency of the characterization of wild olive phenotypes methods, and it is recommended to be used in olive biodiversity studies.

Abstract

Chemical insecticides have a major role in insect pest control, especially organophosphates insecticides; their non-selective mode of action may cause devastating environmental problems. In vitro assays with cultured insect cells were used as the first step in toxicity studies and to achieve a simple, low cost and rapid system that allows testing of insecticides. In this study, the effect of the organophosphorus pesticide “Dimethoate” was evaluated in vitro on cultured Sf9 cell line.  Cell viability was estimated using Trypan blue stain. Analysis of regression was used to estimate the 50% inhibition of cell growth (IC50), resulting in: IC50 =75µM. Deformation of treated cells was observed, as cells became larger and included cavities; number of deformed cells was positively correlated with concentration of Dimethoate. This research presents an important example of applying in vitro insect cell culture as a useful tool in the prescreening of insecticides’ effect and mode of action, especially newly introduced ones.

Key words: Insect cell lines, In vitro test, Dimethoate, IC50.
