The wide geographical spread and the exponential growth of the numbers of goats
around the world clearly demonstrate the ability of these ruminants to adapt to
harsh climates and grazing land. The aim of this study was to assess the genetic
divers
ity of 42 samples of Syrian goats from many domestication stations including
Jabali, Shami and hybrid (hybridization between both Shami and Jabali). The study
was done by DNA extraction of these samples, application of SSR technology using
7 microstellite markers. The alleles number of markers were 29 alleles, at a rate of
4.1 allele for each genetic locus. The number of alleles of each locus ranged from 3
alleles in genetically markers (BMS1714, INRAD07, SRCRSP09) to 8 alleles at the
genetic marker SRCRSP01. The rate of allele-frequency across all studied genetic
sites ranged from 0.071429 with the molecular size of 210 bp for the McM527
genetic site to 0.97619 with a molecular size of 55 bp for the SRCRSP09 genetic site.
This study was carried out at Hamah Research Centre during 2014/ 2015 season
on Shami goat flock (25 heads) in late pregnancy to determine some indicators of
pregnancy toxemia in Shami goat. The blood samples were taken from both groups
at differe
nt stages of late pregnancy to be used in several biochemistry tests (BHB,
NEFA, glucose, total protein, albumin and triglyceride). The blood tests showed a
significant increase (p≤0.01- 0.001) in BHB and NEFA, and a significant decrease
(p≤0.05) in glucose during 2- 3 weeks antepartum, but one week antepartum for
the albumin. But regarding triglyceride it was high (p≤0.05) during 1- 3 weeks
antepartum. It was noticed a trend to acidic pH in urine of the tested animals.
Also, the acetone was positive (+++) one week before partum. In conclusion, it is
important to evaluate some clinical and biochemical parameters, besides acetone
and pH estimation in urine for the early diagnosis of risks of pregnancy toxemia
in Shami goat’s prior the birth time. This can give time for owners to take some
protection procedures.
The aim of this search was to compare two Laparotomy (Flank And mid
ventral). Twelve (n=10) apparently healthy goat of native breed and different
sex.
This study was performed to investigate the analgesic effects of lidocaine ,
Xylazine and Lidocaine / Xylazine combination in eye regional anesthesia.
Twenty four goats were randomly designed in 4 groups .
β-galactosidase enzyme was isolated from the new born goat brain by nine
methods, It was found that the sodium acetate 0.2 Mole/Liter +0.2Mole/Liter
NaCl PH5 method have given the highest specific activity of crude enzyme in
comparison with the ot
her methods. Also, this enzyme was purified by using
four methods, the second one (cold acetone) was the butter. As a result the
purification fold was about 135.46 times and the yield about 77.14% by using
Sephacryl S200 (second step). This enzyme is 187.437 KDa as a molecular
weight.
Some characteristics of β-galactosidase enzyme that was isolated from a new
born goat brain were studied. This study concluded that the enzyme is glucoenzyme
in which the carbohydrate part constitutes 22.1% in accordance with
phenol –sulfate acid
method.
The optimum pH for the enzyme activity is 5.5. The enzyme lost its activity
completely at pH8.5, and showed great stability at the range of pH 4-6.
The results indicated that the optimum temperature for the enzyme activity
is 55Co at the optimum pH. The stability temperature for the enzyme is
35-60Co.
The analytical results of 5%lactose solution hydrolyzed by the enzyme have
indicated that the hydrolysis rate is between 40% after 60 minutes, to 95%
after 270 minutes.
The research was carried out in Karahta Research Station for Shami goats
by using 84/head/Shami kids (122±18.65 days old and 18±3.77 kg body weight).
This trial continued for a 90 day period. Its goal was to find out the possibility
of reducing th
e offered concentrated feed in about 40% from the regular
requirements for growing and replacing it by improving the nutritive value of
the offered straw when they treated with urea, molasses or both of them.
The Animals divided randomly into six treatments according to the offered
feed for each treatment as the follows:
Untreated wheat straw (control), wheat straw treated with 20% molasses,
1% urea, 1% urea and 20% molasses, 2.5% and with 2.5% urea and 20%
molasses.
This study was carried out using white German goat race during 2000-2001
at the Research Center of Animal Production Division, Humboldt University,
Berlin, in order to examine the validity of the Lactocorder instrument, which
has been used for det
ermination of milking curve of cows, to determine the
milking curve of goat, and to study the timing changes of this curve.
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.
This study was carried out at the Shami Goat Improvement Station at
Karahta. Twenty one week old Shami male goats were used to measure the
concentrations of testosterone and LH hormones in plasma over a period of 21
months, using the Enzyme Linked
Immune Sorbent Assay (ELISA), in order to
determine the sexual puberty age. All kids were housed and managed under the
husbandry regimes applied at Karahta station.
