Abstract

The concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb), cadmium (Cd) in propolis and bees wax were determined by using atomic absorption spectrophotometry. The samples were collected from five different locations of Latakia; Qardahah (Asitamo), Haffeh (Dabba), Jableh (Snouper), Latakia city (Al-Ramel Al-Shamali\ Autostrade of Al-Jomhouria) and Eastern Entryway to Latakia, during the spring and autumn in 2014. The results showed that there were significant differences in the concentrations of all tested elements between the locations, it was also demonstrated significant differences between the mean concentrations of all elements in propolis and  bee wax except cadmium. The concentration of nickel, zinc and lead were significantly higher in propolis than bees wax, except the concentration of copper which was high  in  bees wax. The concentration of copper, zinc, nickel and lead was similar in both spring and autumn, unlike the concentration of cadmium in autumn (0.019 ppm) which was higher than in spring (0.009 ppm).

Key words: Bee, Propolis,  Bees wax,  Copper, Zinc, Nickel, Lead, Cadmium.

Abstract

The study was conducted to evaluate the effects of supplementing selenium, zinc and combination of them on the level of antioxidants and some blood biochemical indicators of 12 individual Kurdi rams, aged between 16 – 18 months. The rams were divided to four groups and each group contained 3 rams. The control group, basal diet without Se and Zn, the second group selenium (sodium salinate) was added as 0.5 mg / kg of feed, the third group zinc (zinc sulphate) was added as 100 mg/kg of feed, and the fourth group selenium with zinc were added as 0.5 + 100 mg/kg of feed, then given by gelatinous capsules daily for 90 days. Blood samples were taken from the rams (three for each treatment), on the 30 days, 60 days and before ending the feeding trails (90 days). The results showed a significant increment in Testosterone hormone, blood urea, glutathione (GSH) and Malondialedhyde (MDA) in the blood serum in the groups that added Se, Zn and combinations of them to the feed compared to the control group. An increase in the concentration of the Aspartate Transaminase (AST) and Alanine Transaminase (ALT) in blood serum in the groups that added Se, Zn and combination of them to the feed compared to the control group. In addition, the total protein in the blood serum did not differ significantly between treatments on the 30, 60 and 90 days of the experiment. The results concluded that the addition of selenium and zinc supplements improved significantly of the situation of antioxidants, Testosterone hormone and some serum biochemical indicators of Kurdi rams.
