ABSTRACT
Mixed bee pollens were collected from fields cultivated by sunflower, palm and oxeye daisy plants at Fayoum governorate. The gross chemical composition and the profiles of amino acids and minerals of bee collected mixed pollens were determined. Nutritional experiments were preformed on adult and elderly female rats fed on basal diet and orally supplemented by mixed bee pollen at 2% and 4% levels. Blood samples of adults and elderly female rats were collected at start and after 10, 20, and 30 days of the experiments. Serum total lipids, high-density lipoproteins, triglycerides, total lipids, progesterone and calcium levels were estimated for both adults and elderly female rats. At the end of the experiment, the adult and elderly female rats were allowed to mate and the numbers of fetuses in both cases were counted. The basal diet supplemented with mixed bee pollen induced a lowering lipid effect, increased HDL-cholesterol, progesterone, calcium levels and fertility of elderly female rats
