It is important to study the effect of sex and day-old weight on subsequent weight and body mass index. This study was conducted during the period from 15/10 to 27/11/2017. A total of 79 broiler chicks (Ross 308) (35 male and 44 female) cut was used. Results revealed that the effect of sex was not significant on the body weight of birds at the first, second, third, fourth weeks, whereas the effect was significant (P< 0.05) on the body weight at 5 th week (1648.28 g in males vs 1534.97 g in females). In regards with the effect of the day-old weight the effect was significant (P<0.05) on the body weight for all the five weeks. The body weight of chicks with the highest day-old weight showed the highest body weight at 4 th and 5 th weeks. Also, the results showed that the effect of sex was not significant on the body mass index (BMI) at the first, second, third, and fourth weeks, while the effect was significant (P<0.05) at the 5 th week. The effect of the day-old weight was significant (P<0.05) on the BMI at the 1 st , 2 nd and 5 th weeks. In conclusion: The two studied factors should be taken in our consideration to increase the production and then increase the profitability of broiler projects.

The current work designed to explore the porpolis potential on some characters related with fertility in Iraqi local roosters. Thirty mature white local roosters, age between 27-28 weeks, randomly distributed into three groups (n=10). Treatment 1 (T1) group, control group, taken the standard diet during the research period (ten weeks), each rooster of treatment 2 & 3 (T 2 & T 3) received 0.25 & 0.5 g/day of propolis, respectively. At ten weeks ending, blood samples obtained from vein of wing to evaluate the levels of cholesterol, globulin, albumin, total protein, testosterone hormone, Interstitial cell-stimulating hormone (ICSH) and Follicle-stimulating Hormone (FSH) in serum. Roosters were euthanized and testes collected to determine their length, weight, width and height. Roosters of T 2 and T 3 groups' showed a significant elevation in morphological measurements of testes compared to control group (T1) (P<0.05). In addition, the values of serum globulin, protein, testosterone hormone, ICSH and FSH raised significantly in T 3 and T 2 roosters compared to T 1 group (P<0.05). We can conclude that the Iraqiporpolis plays a vital role in fertility efficiency because its ability to reduce oxidative stress and act as a phytoestrogens leading to improve the testicular size and weight, as well as, enhance the reproductive hormones in Iraqi local roosters.

This study was carried out on 26/5/2019 until 17/6/2019 At local hatchery (College of Agriculture / University of Karbala), to investigate of Different spraying protocols on the eggs of local chicken with the eggs of local chicken with different solutions at variant periods on embryonic mortality during incubation period and on the hatchability of setting eggs. 600 eggs (55 g weight ) used in this study from local chicken divided into three groups each group sub divided into 5 groups spraying by distilled water, olive oil, ethanol alcohol 70%, egg albumen and not treated groups that represented as GW, GO,GE,GC. first group G1 (n = 120) was sprayed at the first day of incubation period, the second group G2 was spraying at beginning of the 2nd week of incubation at aged 7 days, the third group G3 in which the eggs was sprayed at the beginning of 3rd week of incubation at aged 14 days. The results recorded significant reduction of early embryonic mortality in G1 and GC The statistical analysis of the in all groups spraying by ethanol alcohol GE, water group GW and control groups GC. At 14 days of the incubation period, there were no significant differences. At 15-21 days of incubation period, late Embryonic mortality was not recorded in groups treated olive oil, water and albumen when compared with groups treated with alcohol or control. Conclusion, that spraying Iraqi local eggs with water and olive oil at 14 days of incubation period caused high percentages of hatchability of setting and fertilized eggs recorded 100% compared with different materials that used in current research.

اجريت هذه التجربة باستخدام 350 فرخ لحم من نوع ASA آسا الفرنسي لدراسة احلال نسب مختلفة في البروتين الميكروبي 10.0 , 7.5, 5.0 , 0.0 المنمى على الايثانول بديلاً جزئياً عن كسبة فول الصويا في العليقة مع وجود مستويين من الكالسيوم 1.25و 2.5% وبمكررين للمعاملة الواحدة ، وبواقع 25 فرخاً لكل مكرر وقد وفرت الظروف الملاءمة للطيور في قاعة التجربة ، وقد أظهرت النتائج للفترة 3-0 اسبوع من عمر الطيور عدم وجود فروق معنوية بين المعاملات كافة عند مستوى 1.25% كالسيوم ولكافة الصفات ، ولكنها اختلفت معنوياً (P < 0.05) في معدلات استهلاك العلف ومعامل التحويل الغذائي للطيور عند مستوى 2.5% كالسيوم لنفس العمر ، اما للفترة 6-3 اسبوع من عمر الطيور فقد اظهرت النتائج عدم وجود فروق معنوية بين المعاملات كافة وعند مستوى %1.25 كالسيوم ولكنها اختلفت معنوياً (P < 0.05) في معدلات اوزان الجسم الحي ومعدلات استهلاك العلف عند مستوى 2.5% كالسيوم ، اما نتائج الفترة الكلية 6-0 اسبوع فقد انخفضت معدلات كل من وزن الجسم الحي والعلف المستهلك معنوياً (P < 0.05) لمعاملات الاحلال مقارنة بـ T1 عند مستوى %2.5 كالسيوم ، فيما لم تختلف جميع المعاملات في معامل التحويل الغذائي للطيور ، هذا ولم تظهر النتائج فروق احصائية بين جميع المعاملات في نسبة التصافي والوزن النسبي لقطعيات الذبيحة الرئيسية والثانوية للصدر ، الفخذ ، الاجنحة ، الظهر والرقبة والوزن النسبي لكبد الطيور .

This study was conducted at the poultry farm for department of Allatefya Researches, Agricultural and biological researches directorate, ministry of sciences and technology, during the period from 20/8/2019 to 28/12/2019. The aim of this study was to investigate the effect of licorice ( Glycyrrhiza glabra) extract  on some semen traits for local black turkey males. A total of 36 local Iraqi turkey males in 44 weeks old were used in this study. The turkey males were randomly distributed on 4 treatments, each treatments consisted of 9 birds depends on level of licorice addition. Birds were fed during the experimental period on diet contain 2950 Kcal metabolic energy / kg and 18 % crude protein/ kg. Licorice extract was added with drinking water for three levels 5g, 10g, and 15g to treatments T2, T3 and T4 respectively. While T1 treatment stay without any addition as control group. The birds were housed in ground pens (cages) during this study. Semen was collected after ganders trained for two weeks to give semen before the collection began, the semen collection by using abdominal massage procedure. The characteristics were investigated were ejaculate volume, individual motility, mass motility, sperm concentrations, percentage of dead spermatozoa, deformation spermatozoa ratio and spermatocrit.   Results revealed that T4 (15 g per liter) recorded highest values in all traits except in deformation spermatozoa ratio as compared with other treatments (T1, T2 and T3) in most of all experimental period. On the other hand T3 (10 g per liter) achieved high significant effect compared with T2 (5 g per liter) and T1 (0 g per liter), whereas T1 recorded lowest values during all experimental period. However, the overall means of all traits achieved the same trend of treatments effect. While deformation spermatozoa ratio trait had not significant affects recorded from licorice extract addition on this study.
