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 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.
