أجريت تجربة هضم استخدم فيها 105 صوصاً غير مجنسة من أحد الهجن التجارية (الفروج) المتوفرة في سورية من أحد المفاقس القريبة من مكان التربية، جمعت الصيصان عند بدء عملية الفقس دون الحاجة لإتمامها، لتأمين صيصان فاقسة في الوقت نفسه تقريباً.
A digestibility experiment was carried out using 105 unsexed chicks of a commercial broiler breed taken from a hatchery nearby the farm of the experiment. When the chicks started to hatch, the chicks were collected without need to complete the operation of hatching to ensure that the hatching chicks were hatched at the same time.

Research summary
تجربة الهضم التي أجريت على 105 صوصًا غير مجنسة من أحد الهجن التجارية للفروج في سوريا، هدفت إلى تقدير القيم الغذائية لخلطات علفية تحتوي على مكونات غنية بالطاقة والبروتين لاستخدامها في التغذية المبكرة لصيصان الفروج. وزعت الصيصان على سبع مجموعات، كل منها قدمت خلطة علفية مختلفة: الجليسيرين، زيت عباد الشمس، نشاء الذرة، بودرة الحليب خالي الدسم، بودرة البيض الكامل، بودرة الكازائين، ومجموعة الشاهد. أظهرت النتائج أن إضافة الجليسيرين بنسبة 5% حسنت من الطاقة القابلة للتمثيل الظاهرية والحقيقية للخلطة العلفية بشكل معنوي مقارنة بمجموعة الشاهد. كما أظهرت النتائج أن إضافة بودرة البيض الكامل بنسبة 5% أو بودرة الحليب خالي الدسم بنسبة 4% رفعت معامل هضم البروتين بشكل معنوي مقارنة بمجموعة الشاهد. لم يكن هناك فرق معنوي في الوزن الحي ومعامل التحويل العلفي بين المجموعات المدروسة. تشير النتائج إلى أن إضافة الجليسيرين وبودرة البيض الكامل وبودرة الحليب خالي الدسم يمكن أن تحسن من القيم الغذائية للخلطات العلفية المقدمة لصيصان الفروج في الأيام الأولى من عمرها.
Critical review
دراسة نقدية: الدراسة قدمت معلومات قيمة حول تأثير مكونات غذائية مختلفة على القيم الغذائية للخلطات العلفية لصيصان الفروج. ومع ذلك، يمكن تحسين الدراسة من خلال زيادة عدد العينات لتقليل التباين وزيادة دقة النتائج. كما أن الدراسة لم تأخذ في الاعتبار تأثير هذه المكونات على المدى الطويل، مما يمكن أن يكون له تأثيرات مختلفة على النمو والصحة العامة للفروج. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لمزيد من الدراسات حول تأثير هذه المكونات على الجهاز المناعي للصيصان، خاصة في ظل الظروف البيئية المختلفة.

An experiment was carried out using 280 unsexed chicks of a
commercial broiler breed taken randomly from a hatchery after the
start of hatching. The chicks were distributed into four groups of 70
chicks each. The chicks were fed a certain type of
mash feeding for
7 days as follows:
The chicks of the 1st group were given the basal diet directly after
hatching containing 1.2% lysine, This diet is conformed to the
American feed tables of (NRC, 1994).
The 2nd and the 3rd group of chicks were given the diet directly
after hatching but containing 1.45%, 1.70% lysine respectively, and maintaining the rest of the nutrients as in the basal diet.
The chicks of 4th group were given the diet directly after hatching,
but containing 24% protein, and maintaining the rest of the
nutrients as in the basal diet.
After 7 days the chicks of four groups fed a broiler pellet
commercial diet until the age of 42 days.
The results showed the importance of adding lysine to the diet
directly after hatching on the average live weight at the end of the
first week, the differences were significant (P ≤ 0.05) between the
chicks of the third group compared to chicks of the first group. It
was also noted that the increase in lysine in the diet is better than
increasing the crude protein to 24% (P ≤ 0.01) on the average live
weight at the end of the first week. No significant differences were
noticed among the average live weight of the chicks of all groups at
the end of the experiment
An experiment was carried out using 120 unsexed chicks of a
commercial broiler breed taken from a hatchery nearby the farm of
the experiment. When the chicks started to hatch the chicks were
collected without the need to complete the operation of
hatching to
ensure that the hatching chicks were hatched at the same time.
The chicks were distributed into four groups of each group divid into 6
sub groups each sub group contains 5 chicks. The chicks were fed
different diets.
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
G3)) compared to the control (without the addition), which amounted to an average live
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.
Antimicrobial compounds have been used for decades in poultry diets to increase
performance and decrease morbidity particularly in broiler chickens. However, consumer
pressure related to the potential development of antibiotic-resistant bacteria ha
s resulted in
the development of non-antibiotic feed additives that may also improve broiler erformance.
In recent years, aromatic plants and their extracts have received attention as growth and
health promoters. Such products have several advantages over commonly used commercial
antibiotics since they are residue free and they are also, generally recognized as safe and
commonly used items in the food industry. The antimicrobial properties of medical plants
and their extracts have been widely reported because they consist of many active
ompounds such as carvacrol, eugenol,which partition lipids in the bacterial cell wall and
mitochondria, disturbing the structures and rendering them more permeable.
Generally,medical plants are slightly more active against Gram-positive than Gramnegative
bacteria. Medical plants are well known for their antioxidant activity and show a
considerable effect on increasing the antioxidant capacity of chicken meat because they
consist of many of active compounds such as tocopherol, carvacrol. Spices or their active
principles have been reported to stimulate digestive secretions such as lipase, amylase and
proteases.because they consist of many active compounds such as anothol, eugenol.
Variable effects of medical plants and their extracts on the productive performance of
broiler have been reported. The majority of experimental results indicate improved body
weight gain or final body weight and feed conversion ratio.
The present study was conducted at the First of May Station belongs to the
General Commission For Scientific Agricultural Research (GCSAR) at
Damascus during 2011 and 2012 growing seasons to estimate gene action,
heritability, genotypic and phenot
ypic coefficient variations (GCV, PCV) and
genetic advance for two crosses of soybean. The five population (P1, P2, F1, F2,
F3) of each cross were grown in a randomized complete block design (RCBD)
with three replications in order to evaluate oil and protein contents and seed
yield traits. Results of mean square analysis showed significant differences
(p<0.05) among mean values of the five populations for all studied traits
between the populations of each cross. The second cross achieved high broad
and narrow sense heritability (66%, 44%) for protein content, high value of
phenotypic and genotypic variations in seed yield in the second cross achieved
(18.03,17.30) and high value of expected genetic advance was obtained 11.09%.
In most traits, epistasis of the dominance × dominance type of gene action
occupied the first rank in order of importance in controlling inheritance of the
evaluate traits in both crosses indicating the importance of selection in late
segregating generations to improve these traits. These findings are supported
by high values of heritability, which was related with low to moderate expected
genetic advance in two crosses.
