A reverse transcriptase-polymerase chain reaction (RT-PCR) technique was used
to detect infectious bronchitis virus (IBV) in the commercial broiler flocks in
Syria. 50 tissue samples were taken from tracheal tissue, trachea and kidney of
the broil
ers suspected of infectious bronchitis (IB) from different governorates
of Syria i.e. Latakia, Tartous, Hama and Damascus countryside. RNA was
extracted directly from the tissue samples and then RNA was converted to cDNA
by RT-PCR technology; PCR reaction and Nested PCR interaction were carried
out sequentially. The primers used in the RT-PCR reaction were selected from
the S1 gene (spike), where mutations of the virus genome were concentrated in
this region (the hypervariable region). Some positive samples (10) were injected
at an age of 9-11 days old SPFEE-specific pathogen free embryonated eggs
according to the methods adopted in virology. This research was carried out at
the laboratories of Latakia Research Center, General Commission for Scientific
Agricultural Research GCSAR, in cooperation with the PCR laboratory at the
Faculty of Veterinary Medicine in Hama. The results showed the existence of 37
positive case for RT-PCR (74%), and the infectious embryos showed clear and
characteristic anatomical lesions of the infectious bronchitis virus after 5-6 days
post injection, delayed and undeveloped fetal (dwarfism), fingertip entanglement
and hemorrhage compared with the negative control. The results also showed the
sensitivity and speed of the RT-PCR test in the detection of the IBV virus.
The effect of adding two organic acids(formic acid, acetic acid). with broiler drink
water was tested to evaluate their efficacy on the their performance and health Groups
treatment consumed amounts of feed that are greater than the control but for
The results in
the six trials showed superiority of the feed conversion ratio and the final weight of broiler
in the two groups that was added complex to its drink water, compared to the control with
significant differences at 0.05.
There was no significant difference between the replicates of each trial on its own
while the results of laboratory parasite testing of samples litter showed that the number of
oocysts in the litter was the lowest in the treatment groups with significant differences
compared to the control. It was noted that the number of oocysts in litter increased until a
certain age and then began to decline.
The results also showed reduced mortality in all trials with treatment and there were
no significant differences in treatment groups compared to the control.
This research carried out in the Video Center for Research on Animal Production of
the Faculty of Agriculture at Tishreen University with the beginning of the summer of
2010 in order to study the possibility of improving the performance of broiler
chickens
under the conditions of the coastal area and increase economic returns.
Search Results showed that the addition of black bean and thyme powder by 0.5% to a
low-energy diet led to increased average live weight of age (9-28) days totaled 864.9 g

weight has 850.7) g) of the same age
FCR feed conversion ratio stood at 2.63 at the group G1, compared with 1.89 when the
Control CSearch results also showed that the addition of 0.25% of the black bean and
thyme powder led to the live weight increase of 848.6, compared with 670.7 members G1)
g) FCR feed conversion ratio stood at 1.96 at the G4 Group added (0.25% of the black
bean powder and thyme), compared with 2.63 at the G1 group.
This research aims to assess and study the evolution of broiler breeding in Syrian
Arab Republic in general and in Syrian Coast and Lattakia Governorate particularly, in
period between 2003 – 2012, and account of production costs for all stages of
broiler
breeding according and analyze these costs, and economical evaluation of production
broiler by using some economic indicators, and clarifying the impact of crisis in Syria the
process of broiler breeding and production in Lattakia Governorate, by comparing the
prices and costs befor and after the crisis.The research shows the production efficiency for
table chicken breeding in Lattakia Governorate amounted to /1.85/ in year 2010, and /1.20/
in year 2014, while the economic efficiencyreached /1.72/ in year 2010, and /1.09/ in year
2014, the return of capital period was 1.3 years in 2010, then it became 9.8 years in 2014.
Two hundred fecal samples were randomly collected from various
aged broiler flocks farms, which suffered from diarrhea or
respiratory problem or both in Tartous and Latakia Provinces of
Syria.
This study demonstrated the infection of the broiler
flocks with
Cryptosporidium in Tartous Province of Syria with a rate of 5.6%
only.
The results of tests based on morphology and size of
Cryptosporidium oocysts showed that the parasite is probably
C. baileyi which ranged in size about (6 μm X 4.5 μm).
Two experiments were carried out to determine the effect of flock
age on egg laying pattern, floor laying, egg weight, hatchability,
fertility and body weight at hatch. Eggs were collected from 32and
43 wk old Cobb 500 broiler flocks for 6 consecu
tive days hourly to
study egg laying pattern and floor laying (experiment 1). In
experiment 2, 2916 eggs from the flock at 32 ,43 and 49 wk old
were used to determine the effect of flock age on egg weight,
hatchability, fertility and body weight at hatch.
This study aimed to determine the effect of antifungal drug (copper
Sulphate) on blood picture of broiler chickens Vaccinated with
Newcastle Disease Vaccine, We used the drug being tested by two
doses: (50, 100) ppm from the age of 7 till 45 Days.
We used /150/
chick were divided into three equal groups.
Coccidiosis is one of the major parasitic diseases of poultry . The disease has s great economic impact in poultry due to resistance of the organisms to anticoccidial drugs.
This study aimed to determine the effect of anticoccidial drug (Sulphaquinoxaline), that deployed in poultry farms in The Syrian Arab Republic, on some blood parameters, of broiler chickens for the commercial type(Ross), that available in Syria. We u
sed drug being tested by two doses(therapeutic dose and a double therapeutic dose), as the following: (125, 250)ppm, respectively .The experience birds that braved /120/ chick at aged one day were divided to three equal distribution groups (Control, group(1), Sulphaquinoxaline, group(2) at concentration(125)ppm, Salafaquinoxaline, group(3) at concentration(250)ppm). The experience period continued for(45) days. The anticoccidial drug were presented continuously with fodder, and the blood samples were collected three times during this period. The blood samples were taken from broilers at the age(15 - 30 - 45) days. 10 samples were taken of each group from indentified three groups, then lab tests were done on the blood picture. These Tests included determination of the values of total protein, albumin and Globulin in blood serum, and also it included determination the values of some mineral elements in blood serum. These elements contained[Ca- P- Mg ] in serum.
This study aimed to determine the effect of anticoccidial drug
(Sulphaquinoxaline), that deployed in poultry farms in the Syrian
Arab Republic, on some biochemical parameters, of broiler
chickens for the commercial type (Ross) available in Syria.
