In this study are evaluated the effects of addition of vitamin E and Selenium on the sperm
motility and vitality of Syrian rooster, at storing at 4 C⁰ for 24 and 48 hours. The Results
showed that the addition of both vitamin E and E with Selenium i
mproved the sperm
vitality and movement, but the vibration movement was decreased during 24 and 48 hours.
Our results also showed that the concentration of (5mg E+0.6mg Se) gave the highest
value of sperm vitality, rapid and slow movement with 17.79%, 10.65%, 8. 28%
respectively for 24 hours, and 19.29%, 10.06% 10.37% respectively for 48 hours. Whereas
the concentration of (10 mgE+0.6 Se) gave the lowest values of mentionned parameters.
Contrarily, the first concentration gave the lowest and the second the highest values of the
vibration movement. Finally, the statistical analysis (p<0.001) showed a significant
difference between studied parameters.
An experiment was conducted on maize crop (Zea mays L.) in plastic pots in two
different soils (Qurna soil, which is poor organic matter and the other soil from
Maysan marshes, which is rich in organic matter), to study the effect of selenium,
sul
fur and phosphate and their interaction on dry weight of shoot of maize crop.
Selenium was added at four levels (0, 10, 20 and 40 g Se ha), sulfur at three
levels (0, 30 and 60 kg S ha), and phosphorus at three levels (0, 60 and 120 kg P
ha).
The glassy carbon electrode has been used as working electrode,
to study the electrochemical behavior of Se(IV), by using anodic
stripping voltammetric method (ASV) in acidic media HCl. We
found that The reason for the absence of analytical signal
s
expressed on flow any electrodic process due to reduction
mechanism of Se(IV) on glassy carbon electrode from Se4+to Se2-
and formation H2Se.
