Kamel Z. Mahmoud, Saad M. Gharaibeh, Hana A. Zakaria and Amer M. Qatramiz
Asian-Australian Journal of Animal Science
ABSTRACT : Forty-eight 40-wk-old Hi-sex laying hens were individually caged in an environmentally controlled house to evaluate the effect of garlic (Allium Sativum) juice administration on egg production, egg quality, and yolk cholesterol. Garlic juice was prepared by blending pealed garlic cloves with distilled water (1:1, w/w). Hens were randomly divided into four equal groups; one served as a control and the other three groups were individually gavaged, 3.75 ml, 7.5 ml, or 15 ml garlic juice, three times a week, which respectively represented 0.25, 0.50 and 1% of body weight. Egg production was recorded on a daily basis; egg weight, albumen height, albumen and yolk pH, Haugh unit, and bacterial count of E. coli-challenged eggs were recorded at day of oviposition (day-1) and after 5 and 10 days of storage at room temperature. Yolk cholesterol content was analyzed for five successive weeks. Garlic juice increased (p

Effect of sources and levels of Dietary zinc on the performance, carcass traits and blood parameters of broilers
Zakaria H.A.. Jalal M, Al-Titi HH, Souad A.
Brazilian Journal of Poultry Science ABSTRACT A total of 400 one-day-old, straight-run, commercial (Ross 308) broiler chicks were used to evaluate the effects of two dietary levels of zinc (Zn) sources on broiler chick performance, carcass traits and blood parameters. Corn-soybean diets were formulated for three rearing phases (starter, grower and finisher). The two dietary treatments applied consisted of the addition per kg of diet of 80mg of inorganic Zn (ZnO) (T1), or 80mg of ZnO plus 42mg of an organic Zn-amino acid complex (Availa-Zn120; Zinpro Corporation, Eden Prairie, MN, USA), totaling 122mg of the combined organic and inorganic Zn sources (T2). Birds were distributed according to a completely randomized design in the two treatments with eight replicates (pens) of 25 birds each. Feed and water were provided ad libitum. On day 42, blood samples were taken from four birds closest to the group average weight per replicate (32 per treatment) and then slaughtered for carcass evaluation. The results of this study did not find any significant effect of either of the evaluated Zn sources on broiler growth performance. Mortality rate was significantly lower (p

Functions of Duckweed as a natural water purifying agent and as a feed source for laying hens
Maisa'a W. Shammout and Hana zakaria
International conference on Mathmatical , Computational and statistical Sciences and Engineering (MCSSE, 2016) Keywords: Jordan, Irrigation ponds, Duckweed, Water purifying, Laying hen, Egg production. Abstract. Duckweed plants have been seen to grow naturally in Jordan’s irrigation ponds. Their massive reproductive capacity causes the formation of a dense cover of these plants, and raises the attention towards studying their functions as a natural water purifying agent, and as a feed source for laying hens. Therefore, this paper examined the average percentages of nutrients’ removal by duckweed, and the production performance of laying hens. The results showed that the growth of duckweed in irrigation ponds serves as a purifier for irrigation water. These plants remove an average of 20% Ca, 33% Mg, 21% K, 13% Cl, 25% SO4, 35% PO4, 1.5% Na, and 40% NO3. The analysis of the water source in irrigation ponds showed that the heavy metals (Zn, Cd, Pb, and Cu), are within Ideal Detection Limits. The analyzed duckweed samples contain; 26% protein, 2913 Kcal/Kg metabolizable energy, 5.2 fiber, 3.1% fat, 4.3% Ca and 0.86% P. A feeding trial was conducted on laying hens by replacing part of soybean with percentage of duckweed, and proved its efficiency on laying hens egg production. The results highlight the importance of this research to undergo further studies as to the utilization of these plants as a water purifier, and as the future promising feed source for livestock sector.
Water lentils (duckweed) in Jordan irrigation ponds as a natural water and protein source for broilers
Maisa’a W. Shammouta,*, Hana Zakaria
A B S T R A C T The growth of wild water lentils (duckweed) in Jordan’s farm irrigation ponds has focused attention on the need to study the functions of these plants as a natural water bioremediation agent and as a potential protein source for broilers. This paper examined the water source and water quality (nutrient composition) of irrigation ponds that support duckweed plants and their suitability as broilers feed. The results showed that the source of the irrigation ponds is Zarqa River, and the analyzed water quality parameters of the source fall within the allowed limits set forth in the Jordanian Standard. The growth of duckweed in farm irrigation ponds reduces the nutrient supply to irrigated crops and serves as a purifier of irrigation water. These plants remove an average of 20% Ca, 33% Mg, 21% K, 13% Cl, 25% SO4, 35% PO4, 1.5% Na, and 40% NO3. Fresh duckweed contains approximately 94% water and 6% dry matter; the average nutrient concentrations in dry matter are 26% protein, 4.16 % N, 5.2% fiber, 3.1% fat, 0.86% P, 2.4% K, 4.3% Ca, 0.88% Mg, 0.2% Fe, 1.62% Cl, 0.16% Na, 0.008% Zn, 0.07% Mn and 0.002% Cu. This research reveals the potential for Jordan to examine the availability of duckweed in farm irrigation ponds and their function as water bioremediation agents and their suitability as a protein and nutrient source for broilers. If harvested at frequent intervals and dried, water lentil plant (duckweed) could be of great benefit to Jordan's livestock sector, especially with regard to poultry, where feedstuffs are limited in supply and prices are typically high. ã 2015 Elsevier B.V.

T.M.A. TAHA, H.Zakaria, M.Jalal and S.Bauwens
Journal of applied Animal Nutrition
Summary The present study was conducted to determine the effect of dietary supplementation of organic acids combined with synergistic components, using a commercial product Lumance™ (Innovad NV, Belgium) containing esterified butyrins, propionic acid and sorbic acid, with medium chain fatty acids (capric, caprylic, and lauric acid) and plant extracts, on the productive performance and mortality of growing broiler chickens. A total of 492, one day old broiler chicks (Ross 308) were randomly allocated to four experimental treatments either with an unsupplemented control or 0.05, 0.1 or 0.15% organic acid mixture in a pelleted corn/soyabean meal diet, which were offered ad libitum until 35 days of age. Results showed that birds in the 0.1% supplemented diet group gave significantly higher (P < 0.05) body weights during the first two weeks of age and increased weight gain during the first three weeks of age. The inclusion had no effect on broiler mortality. Keywords: broiler: organic acid: butyrate: performance: mortality: Lumance™ (Received 28 March 2014 – Accepted 11 May 2014)

Differentiation of Avian Pathogenic Escherichia Coli strains from Broiler chickens by Multiplex Polymerase Chain Reaction (PCR) and Random Amplified Polymorphic (RAPD) DNA
Dirgam Ahmad Roussan, Hana Zakaria, Ghaassan Khawaldeh, Ibrahim Shaheen
Open Journal of Veterinary Medecine
Abstract We examined 50 Escherichia coli (E. coli) strains isolated from broiler chickens between January 2013 to March 2014 in order to evaluate the epidemiological prevalence of avian pathogenic E. coli (APEC) in Jordan by multiplex PCR and random amplification of polymorphic DNA (RAPD) tests. The multiplex polymerase chain reaction (PCR) which was used as tentative criteria of APEC targets 8 virulence associated genes; enteroaggregative toxin (astA), Type 1 fimbria adhesion (fimH), iron-repressible protein (irp2), P fimbriae (papC), aerobactin (iucD), temperature-sensitive hemagglutinin (tsh), vacuolating autotransporter toxin (vat), and colicin V plasmid operon (cva/cvi) genes. The number of detected genes could be used as a reliable index of their virulence. E. coli strains already typed as an APEC always harbor 5 to 8 genes, but non-APEC strains harbor less than 4 genes. Assuming the criteria of an APEC is possession of 5 or more virulence associated genes; we found that all 50 E. coli strains were classified as APEC strains. The RAPD analysis showed that the E. coli strains could be grouped into 35 of RAPD types by using these two different RAPD primer sets, RAPD analysis primer 4 5'AAGAGCCCGT5', and RAPD analysis primer 6 5'CCCGTCAGCA3'. The current study confirmed the endemic nature of APEC in broiler flocks in Jordan. It is essential that the biosecurity on poultry farms should be improved to prevent the introduction and dissemination of APEC and other agents. Furthermore, farmers need to be educated about the signs, lesions, and the importance of this agent.

Wild water lentils plant(Duckweed, Lemna sp.) in nutrients removal of Jordan's irrigation ponds
Maisa'a W. Shammout, Hana Zakaria
Biomedical Engineering and Environmental Engineering Abstract In Jordan, the obvious availability of water lentils plant (duckweed, Lemna sp.) in the irrigation ponds has raised the attention for the need to assess its efficiency in the removal of nutrients. This paper demonstrates the environment that integrates the existence of water lentils and their effect in ponds filtering. At farm irrigation ponds, the results of the average percentage removal of Ca+2 is 20%, Mg+2 is 33%, K+1 is 21%, Cl-1 is 13%, SO4-3 is 25%, PO4-3 is 35%, Na+1 is 1.5%, and NO3-1 is 40%. Results show, that the growth of the wild water lentils plant in farm irrigation ponds is in fact a reducing agent of the nutrients supply to irrigated crops, and as a purifier to irrigation ponds. The Results of this project are to establish a fundamental phase in Jordan for further studies as to the utilization of these plants as a protein source for broilers.

Water quality and growth trend of aquatic plant duckweed:management and benefits
MW. Shammout and H. zakaria
Environmental Engineering and Computer Application, chapter 17 ABSTRACT: This paper focuses on the irrigation water quality and on growth trend of aquatic plant so called duckweed (Lemna sp.) in farm ponds. It also focuses on duckweed growth management utilizing its benefit at farm level. The results showed that the water quality analysis in mg/l of Ca is between 120-113, Mg 48-40, K 22-18, Cl 349-340, SO4 220-188, PO4 7.6-6.3, Na 212-205, and NO3 38-31. The average protein value in dry matter of duckweed is 26%. At laboratory, duckweed’s growth showed an approximately exponential trend that continues until fronds face scarcity of nutrients. This requires the involvement of local farmers towards plant growth management. In this study, 50% of duckweed growth should be harvested every four days to be utilized as future promising feed source for broilers. Further studies will be conducted on the duckweed’s benefit values.
