Abstract

Seven cyanobacteria groups recorded in Wadi-EL-Natrun lakes included five
genera (two Sp < /em>iro/ina, two Oscillatona • one Nostoc, one Ch/om/fa and one ~avicu/s) .   Spirofina was isolated from EI-Khadra lake. Behelra, Egypt. The alga was
identified as Spiro/ina p/atensis, and purified as axenic strain. Effect 0 antibiotic
treatment on the Spiro/ina p/atensis was studied. Bacterioplankton were different in
their antibiotic sensitivity, ampicillin was more effective. Axenic Spirufina p/atensis
strain (bacteria free) was cultivated on a large-scale. The dry biomass algal yield
contains as high as 60 % crude protein, Sp < /em>irofina dry biomass added to t~e diet of
Rahmany male sheep in the rate of 50g/Kg signifICantly increased Ca, P, Mg and Cu
concentrations in tl'le blood serum of the animals. This treatment reduced t e period
to puberty and sexual maturity to 69 % of that in control animals. Moreover, addition of
Spirofina to the diet significantly increased semen volume, semen activity and number
of sperms in unit volume. As Sp < /em>iro/ina could optimize tI'le blood picture and
accelerates growth of male sheep, it could be recommended as growth prcroter in
the diet of sheep and similar animals.
