Hameed AL-Dalawi Department of Animal Production, College of Agriculture, Kirkuk University, Iraq Abstract This experiment was conducted in the poultry field of the department of animal production at the faculty of Agriculture/Kirkuk University for the from 2019/10/1 until 2019/12/10 and for 70 days (10 weeks) with the aim of studying the effect of using different levels of Gynura procumbens leaf powder on the productive qualities of white chicken type ISA Brown use 144(24) week-old chickens randomly distributed on 6 transactions and by 4 repeaters/transactions and each repeater 6 birds placed in battery cages with four floors and each floor contains four chickens, distributed on 6 transactions T1(control), T2 Contains Gynura procumbens 0.5%, T3 Contains Gynura 1%, T4 Contains Gynura 1.5%, T5 Contains Gynura 2%, T6 T5 Contains Gynura 2.5% .The results of the statistical analysis showed a moral superiority (p0.05) for gynura transactions we find the second and fourth period and the general rate exceed T3, T4, T5 and T6, and in the third period morally superior to the T4, T5 and T6, In the weight of the eggs, the weight of the eggs exceeded in the first and second period the T5 and T6, while the third, T4,T5 and T6, and emerged in the fourth period morally superior to the T4, T5 and T6 and in the general average the third T4, T5 and T6 , In the egg mass we find that the T4,T5 and T6, second, third and fourth period sits above the T3,T4,T5 and T6 and at the general rate is higher than the T6 , The rate feed consumption in the second period is higher than T6 and in the third period is higher the second T3,T4,T5 and T6 and the general rate is higher than the T5 and T6, The food conversion factor in the first period exceeds the T1, T2 and T3 in the second period exceeds T1,T4,T5 and T6 and in the period exceeds T3,T4 and T6 and the fourth period exceeds T1 and the general rate exceeds the T1 and T2 .

Introduction Eggs are considered important in human life because it is a good food source and most studies and research try to improve the mechanisms of egg production and discovered that increased use of antibiotics has side effects as a result of their accumulation in animal products and their negative impact on the health of consumers (Greedy and others, 2015), Avoid the use medicines and recent research and studies have tended to use herbs and medicinal plants to improve the production capacity of meat and eggs and their other beneficial effects of the overall health of chickens and humans (Stadelman and Cotterill, 1998), Food additives play a major role in improving the productive, physiological and immune performance of domestic birds (Aminzade, 2012). Gynura procumbens are medicinal plants and powerful antioxidants are important (Rosidah, 2008) for contains flavonoids, soaps and glycosides (Alownahal et al., 2002) Gynura procumbens is a plant that acts as a natural antioxidant and acts to inhibit free radicals (Mustafa, 2010) and the leaves of this plant are non-toxic (Rasidah, 2009) and anti-inflammatory (Iskander, 2002), and anti-cancer (Agusting, 2006), In poultry, it was used as an antioxidant and reduced cholesterol in egg (Ahn and Du, 2000) (Khan, 2007). Material and Methods This experiment was conducted in the poulty field of the department of animal production at the faculty of Agriculture/Kirkuk University for the from 2019/10/1 until 2019/12/10 and for 70 days he used 144 (24) week-old ISA Brwon chicken sat in it, which was brought from a private company in diyala province of riyadh, after 14 days of breeding, the chicken was randomly distributed to 6 transactions at 4 repeaters per 6- repeater 6 chicken, repeater, and the T1 were fed on a standard bead-free. T2 was fed on attic containing 0.5 kg/ton gynura leaf. T3 was fed on attic containing 1 kg/ton gynura leaf. T4 was fed on attic containing 1.5 kg/ton gynura leaf. T5 was fed on attic containing 2 kg/ton gynura leaf. T6 was fed on attic containing 2.5 kg/ton gynura leaf. The 56– day trial period was divided in to four equal periods of 14 days per term, daily egg production, egg weight every, egg mass, weekly feed consumption rate and food conversion coefficient were calculated, analyzed using SAS (2005) the moral differences between averages were tested using the multi-level Duncan (1955) test al amoral level of 0.05.
