| Abstract | ||
| Spiro/ina was isolated (rom EI-Khadra lake Wadi EI-Nalroun, Beheira. Egy~t. The alga was identirled as Spiro/ina p/aten:sis. The isolated algae were cultivated onl a large-scale in 8 basin constructed near the lake. The dry biomass analysis show,d that the algae biomass contains as high as 60 % crude. protein. 5 % fats, 20 Vo carbohydrates. 7 % minerals and 5 % moisture. Unwashed biomass was found 10 be toxic to mice. while mice Injected with washed biomass suspension still healthy survived. Spiru/ina dry biomass added to the diet of Rahmany male sheep in the rate of 50glKg signifICantly increased Ca, P. Mg and Cu concentrations in the blood serum of the animals. The treatment atso reduced the period to puberty and sexual maturity to 69 % of that of control animals. Addition of Spiro/Ina to the diet significantly increased semen volume. semen mass activity and number of sperms in unite volume. The effect of Sp < /em>iro/ina biomass andlor cnude extract on dominant rumen bacteria (13 isolates) was studied. | ||
