This study was carried out at the laboratory of artificial insemination and
embryo transfer in Ezra station Belongs to ACSAD during 2009 to estimate the
efficiency of local diluents (sodium citrate with egg yolk, EYC and skimmed
milk, SM)in compar
ison to Andromed® as a standard diluent for short and long
-term preservation period of semen in Awassi rams. Four rams, two years old
with live body weight 75± 3 Kg, were used. Semen was collected by artificial
insemination twice/ per day per week for 4 months during the breeding season.
Progressive motility and live – dead sperms were evaluated at each step of
semen handling. Results showed that there was a significant effect (p<0.05) for
the ram on ejaculate volume (1.8-2.46 ml) and sperm concentration (2.4-3.8 X
109/ml) and more significant effect (p< 0.01) for the diluents on studied traits
after each step of semen handling. The highest final survival rate of viability
(65.1%) was shown in semen diluted with Andromed® compared with 51.3% in
EYC and 22.3% in SM and the total rates of dead sperms were 41.9, 56.9.
78.9% in the standard, EYC and in SM, respectively. It was concluded that
local diluents can be used for extending and using Awassi semen as a fresh
diluted semen for a short time preservation using SM and as a frozen and
preserved semen for a long time with EYC in artificial insemination programs
and it was suggested that EYC with glycerol can be replaced for Andromed® if
sperm concentrate is increased by 10-15% at dilution.
This Study was carried-out at Shami Goat Improvement Station in Karahta.
Ten growing Shami male goats, aged 8 months, housed and managed under the
same conditions were used to study the semen characteristics. Artificial vagina
was used to collect
semen at weekly intervals, for 13 months to determine the
volume, motility, pH, and sperm concentration using Neubaure- Spectrophotometer
and Spermiodensimeter techniques.
Overall averages and standard errors of volume, motility, concentration,
and pH were 0.9 ± 0.07 ml, 65.24 ± 1.41%, 3.57 ± 0.14 billion/ml, and 6.52 ±
0.07, respectively. Seasonal variations were observed. A positive significant
correlation between volume and motility (r= 0.42, P<0.01) was found, while
negative correlations (P<0.01) between pH and other studied semen
characteristics were recorded.
Linear equations for detecting sperm concentration as measured by either,
Spermiodensimeter or Spectrophotometer were obtained.

Albumin has an important extra cellular antioxidant effect which prevents
lipid peroxidation. This study was conducted to investigate the effect of low
albumin level in patients with chronic moderate renal failure(CMRF) and
nephritic syndrome(NS)
on the susceptibility of LDL to oxidation, and the
protective role of vitamins C and A in this process.
This research was done as a collaboration work between Tishreen University and the
General Commission for Scientific Agricultural Research in Karahta research station for
improvement of Shami goats and Der Al-Hajar station to set tables for normal
values of
some blood and chemical parameters in Awassi sheep during pregnancy to predict any
nutrition or health disorders. Forty seven Awassi ewes in the same age (in the third season)
were used for that purpose. Blood sample were collected from all ewes every month of the
pregnancy period. Thealanine aminotransferase (ALT),the aspartate aminotransferase
(AST), the alkaline phosphatase (ALP), the glucose (Glu) were analyzed.
Results indicated the existence of significant changes (P<0.05) between the
increase and decrease in all indicators studied throughout The study period, which shows
the change in functional status of liver in conjunction with stage of pregnancy.The overall
average of the effectiveness of enzymes (2.05-26.47), (32.65-181.40) and (11.17-79.76)
U/l for each of the ALP, ALT and AST, respectively, and total concentration of glucose
(37,50-95.20 mg/dl) throughout the study period.
