This study used Sixty ISA Brown layers were produced egg of brown layer, all at 22 weeks of age. The objective of this study was to determine the possibility of using hatchery by product as a source of animal protein and its effect on egg of Brown layer hens quality traits. Four levels of hatchery by product were used (0, 3, 7 and 9)% so four treatment were obtained with 5 replicate (3 bird/replicate) for each were used in this study which lasted for five periods (March- July), The duration of each period was 28 day. The result of egg quality traits indicated improvement in thickness and weight egg as compared with control diet. Also the results showed that T3 significantly different (p<0.05) with other treatment in percentage of the shell to egg weight. The results showed there are no significant differences in yolk weight and Haugh unit. The thired on T3 showed significant increase with T2 and T4 in white weight but there were no significant difference with T1. Also T3 showed significant difference in white index as compare with other treatment. All eggs quality traits showed significantly reduced during May, June and July as compare with March and April.

This study was conducted in poultry farm of College of Agriculture, Al-Anbar University. The objective of this study was to determine the effect of partial and total replacement of (Vicia faba L.) instead of Soybean meal and this effect on laying hens performances. Five treatments were obtained with 5 replicates for each. Seventy-five ISA Brown layers were used in this study which lasted for three periods (July-September) the duration of each periods was 28 days.
The results indicated (2.5% Vicia faba L.) showed significant increase (P<0.05) in egg production and egg mass while the control showed significant increase (P<0.05) in egg weight, feed consumption and feed conversion efficiency than other treatments. The results showed that egg production, egg mass, egg weight, feed consumption and feed conversion efficiency were significantly reduced at August than July and September.

This study was conducted in poultry farm of College of Agriculture, Al-Anbar University. The objective of this study was to determine the possibility of using partial replacement of (Vicia faba L.) instead of Soybean meal on egg quality during summer months. Five levels of (Vicia faba L.) were used (0, 2.5, 7.5, 12.5 and 17.5)%, so five treatments were obtained with 5 replicates for each Seventy five ISA Brown layers aged 30 weeks were used. This study lasted for three periods (July-September). The duration of each period was (28 days).
The results indicated significant increase in egg quality when feeding hens an theist included 2.5-7.5% (Vicia faba L.) during the summer month. However, significant reduced in Yolk index, specific gravity and shell thickness at August as compare with July and September.
The results of this study also revealed, no significant differences among different treatments in shape index, Yolk index and Haugh Unit. There's no significant differences between experimental months in shape index and Haugh Unit.

This study was conducted on Al- Muradia Poultry project infested with red mites for the first time in Iraq. Details of morphology of the mites, symptoms of the infestation on the laying hens have been discussed. Treatments of Red mites infestation with malathion 0.5% and formalin 30% revealed that treatments with malathion give the best result (90%) as compared with the treatment with formalin (30%)., also it has been concluded from this study that the affection of caged layer flock has been reported for the first time in Iraq.

This experiment was conducted in Therthar poultry fields of the animal's product Theraar company consist two periods. The first period from one day old up to 20 weeks of age. 315 chicks were used in an experiment included 7 treatments. (3 replicat/ treatment. Each repl. Consist of 15 chicks). The second period of experiment started at 21 weeks up to 40 weeks of age. 189 laying hens of the first peroid were used in an experiment contained 7 treatments (3 replicat/ treatment. Each repl. Consist of 9 hens). Two periods included, the first treatment considered as control (T1) without any additive, in the 2nd t‌reatment (T2) supplemented with 3kg local probiotic / ton feed , the 3rd t‌reatment (T3) supplemented with 5kg local probiotic / ton feed, 4th t‌reatment (T4) supplemented with 7kg local probiotic/ ton feed, the 5th t‌reatment (T5) supplemented with 1kg Biotronic SE/ ton feed, the 6th t‌reatment (T6) supplemented with 2kg Biotronic SE / ton feed, the 7th t‌reatment (T7) supplemented with 3kg Biotronic SE/ ton feed. The results of the first stage showed that using 3, 5 and 7 kg of local probiotic/ ton feed caused significant reduction (P < 0.01) in feed intake as compared with Biotronic SE treatment and control treatment. Significant improvement (P < 0.01) was obtained in feed conversion coefficient in local probiotic and Biotronic SE treatments compared with control treatment at 20 weeks of age. The results of second stage showed Significant improvement (P < 0.01) for treatments with added local probiotic in egg production rate (HD%),egg numbers for hen, feed conversion coefficient, accumulative egg mass and meat and blood spots. and significant reduction (P < 0.01) in accumulative feed intake as compared with control treatment. The treatment with added 2 kg Biotronic SE / ton feed improved significantly (P < 0.01) as compared with control treatment in egg production rate (HD%), egg numbers for hen, feed conversion coefficient, accumulative egg mass and meat and blood spots. But treatments of added local probiotic improved significantly over Biotronic SE treatments in most productive traits except accumlative feed intake during the accumulative period (140 days).

This experiment was conducted in one of privet commercial field at Al-Nahrowan , South of Baghdad, from 8/11/2005 to 17/7/2006. Force resting were used to face low prices of eggs because of avian influenza outbreak, 33 thousand of brown layer (ISA Brown) from 48 to 83 weeks of age (36 weeks) were used, the layer were distributed into 5 houses (mean of layer were 5500 to 6500), force resting were conducted at 61 weeks of age , the layers were fasted for 15 days, after that , the evaluation were lasted for 13 weeks before and after force resting.
The results from this study showed that force resting significantly improve accumulated egg at rate of 10.92 egg/layer/13 wks , also, significantly improve feed conversion at rate of 14.90 gm per egg, also, daily feed intake were significantly improve at rate of 6.8 gm/layer/day for period after force resting. The conclusion of the study was the force resting is a good method for some problem that faces layer management.
