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.
