Abstract: This study was conducted in poultry farm in animal resources department, College of agriculture, Diyala University during period 1\2 to 1\4 2015 to determine the effect of adding different levels of date palm pollen in productive performance and some eggs quality of layer hens chicken by use of 156hens of lohman brown 50 weeks age. The treatments was 0, 6, 8, 10 gm.\kgm diet (T1, T2, T3andT4) respectively. The results shows that there was a significant different (p ≤ 0.01) in hen day production which was 84.59, 82.39, 81.53, 77.37 % for T4,T3,T2,T1 respectively ,the cumulative eggs , eggs weight , eggs mass, feed conversation were have a significant different for T4 compared with experiment and control treatments. There was a significant decreased in body weight and feed consumption for T2, T3 and T4 compared with T1 (cont), there were no significant different in eggs quality except shell weight and thickness which have significant different for date palm pollen treatments.Abstract: This study was conducted in poultry farm in animal resources department, College of agriculture, Diyala University during period 1\2 to 1\4 2015 to determine the effect of adding different levels of date palm pollen in productive performance and some eggs quality of layer hens chicken by use of 156hens of lohman brown 50 weeks age.

Abstract: Background: There are many factors affecting successes of quail production system , one of important factor is provide sufficient number of egg for needs of hatcheries to produce chicks . This study was conducted in poultry farm of Animal Resources – College of Agriculture – University of Diyala - Iraq, to determine suitable conditions for storage of Japanese quail eggs belong to three varieties of Japanese quails( White , Black and brown plumage color ). Materials and Methods: Eggs from three varieties allocated in two groups represented two storage temperatures 7 C° and 20 C° (average room temperature ) , and each temperature group divided into four sub-groups represented storage periods length 3 , 7 , 10 and 14 days , thus the total number of egg groups were 16 groups. The experiment performed in factorial experiment 3 × 2 × 4 for three factors included variety, storage temperature and storage period , conducted in Randomized Completely Blocks Design with three replicates. The experimental flock consist of 450 birds belong to three varieties , the eggs collected daily and stored according to these various treatments before entered the incubator , and after hatching of eggs , the data recorded for hatchability and embryonic mortality percentages for treatments. Results: The results showed that the black variety quail has significant superiority in fertility ( 80.19 %) with compare to White and Brown varieties ( 69.07 and 68.03 % respectively ) . There were significant effect ( P< 0.05 ) of storage period on hatchability , hence there were significantly decline in hatchability after storage period for 14 days ( 36.58 %) , also there were significant interaction between varieties and storage periods . While there were no significant effect of storage temperature and other interactions on hatchability and embryonic mortality percentage.Abstract: Background: There are many factors affecting successes of quail production system , one of important factor is provide sufficient number of egg for needs of hatcheries to produce chicks .
