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.

Research summary
تتناول هذه الدراسة تأثير استخدام النشاء والكاراجينان في الخلطة العلفية على الكفاءة الإنتاجية لصيصان الفروج. تم إجراء التجربة على 120 صوص من إحدى هجن الفروج التجارية، حيث تم توزيعها على أربع مجموعات غذائية مختلفة. المجموعة الأولى كانت مجموعة الشاهد التي قدم لها خلطة علفية تقليدية، بينما تم تقديم خلطة علفية تحتوي على 5% نشاء للمجموعة الثانية، وخلطة تحتوي على 5% كاراجينان للمجموعة الثالثة، وخلطة تحتوي على 2.5% نشاء و2.5% كاراجينان للمجموعة الرابعة. أظهرت النتائج عدم وجود فروق معنوية في متوسطات الوزن الحي للمجموعات خلال الأيام الثلاثة الأولى من العمر، ولكن بعد اليوم الرابع تفوقت مجموعة الشاهد والمجموعة التي تحتوي على 5% نشاء على المجموعة التي تحتوي على 5% كاراجينان. كما أظهرت النتائج أن استخدام النشاء بنسبة 5% يحسن معامل التحويل العلفي على عكس الكاراجينان، ولم يلاحظ اختلاف في تطور الجهاز الهضمي للمجموعات المدروسة.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو فهم تأثير مكونات الخلطات العلفية على الكفاءة الإنتاجية لصيصان الفروج. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة اقتصرت على فترة زمنية قصيرة (7 أيام)، مما يجعل من الصعب تعميم النتائج على فترات زمنية أطول. ثانياً، لم تتناول الدراسة تأثير هذه المكونات على صحة الصيصان على المدى الطويل، وهو جانب مهم يجب مراعاته. ثالثاً، كان من الممكن تضمين مجموعات إضافية تحتوي على نسب مختلفة من النشاء والكاراجينان للحصول على صورة أكثر شمولية. وأخيراً، لم يتم التطرق إلى التكلفة الاقتصادية لاستخدام هذه المكونات في الخلطات العلفية، وهو جانب مهم يجب أخذه في الاعتبار عند تطبيق النتائج في الواقع العملي.

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.
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
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.
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.
By the time of hatching, the residual yolk sac (RYS) should be completely internalized into the body cavity of the chick through the navel, then the navel should be completely closed (healed). After hatching, the RYS contents are used for general growth including growth of the small intestine. The aim of this study was to verify if there is any effect of navel condition on the growth of small intestinal villi. Jejunum samples from 200 new hatched chicks (at the age of 1 up to 5 days), with the average of 20 chicks per day were obtained, and divided into 2 groups: healed navels and unhealed navels, which were collected and studied histologically. For the first time, this study demonstrated the negative effect of unhealed navel on the growth of small intestinal villi. The results of this study also demonstrated by Morphometric Parameters Measurements of small intestinal villi that the high and the surface areas of villi were increased in healed navel chicks in comparison with unhealed chicks.
