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.

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.

The current experiment was aimed to explore the influencing of the sex-linked dwarf gene on some fertility hormones and biochemical profile in normal local and dwarf roosters. Thirty normal local and dwarf roosters at age 28 weeks were housed at opened system for 6 weeks. At end of 6th week, blood samples collected from all roosters and centrifuged to obtained sera for measuring the concentrations of Interstitial cell stimulating hormone ‘ICSH’, Follicle stimulating hormone ‘FSH’ and testosterone hormone, total protein, albumen, globulin, glutamic oxaloacetic transaminase ‘GOT’, Alkaline phosphatase ‘ALP’, and glutamic pyruvic transaminase ‘GPT’. The statistical analysis documented significant (P<0.05) decline in FSH and testosterone hormone in dwarf group roosters compared with normal local roosters. As well as, the level of total protein and globulin registered significant decline (P<0.05) in dwarf group roosters in comparison with normal local group roosters. On the other hand, the level of hepatic enzymes, GOT, GPT and ALK, recorded a significant (P<0.05) elevation in dwarf group roosters when compared with normal local group roosters. Concluded, that the sex-linked dwarf gene could be affected on hormonal fecundity profile and some biochemical traits in dwarf roosters.

The turkey females were randomly distributed on four groups, each group consisted of 12 birds depend on strain. The strains as follow, (T1): red turkey strain, (T2): bronze turkey strain, (T3): white turkey strain, (T4): black turkey strain. Each group constituted from 3 replicates and each replicate has 4 females. All birds housed under same environmental conditions. Feed and water were available (ad libitum) for all the period. Birds were fed on diet contains 20% crude protein and 2950 Kcal metabolic energy / kg through the experimental period. The flock was reared in a ground cages (pens) during the experiment period. Eggs were collected twice daily. Black turkey strain achieved the highest results, whereas the red strain recorded the lowest results in all traits measured in this study, also white turkey strain had superior on bronze turkey strain in all traits. Results revealed that strain had Significant effected on egg production rate, cumulative eggs number, egg weight, egg mass and feed conversion ratio, but, there was no significant effected for strain on feed intake.
